pharaoh cuttlefish genus

Reid et al. Created to help individuals around the world identify tropical fish Norman (2000) did not distinguish Iranian S. pharaonis from his S. pharaonis s. s., and a photo in Norman (2000: 71) of a mating pair of S. pharaonis from Dubai (in the southern Persian Gulf) is used to demonstrate the zebra lines on the third arms that are supposedly diagnostic for S. pharaonis s. s. If S. pharaonis s. s. is equivalent to our western Indian Ocean subclade, this photo suggests that the Persian Gulf may be home to members of both our Iranian subclade and our western Indian Ocean subclade. Sepia ramani is so far only known from the Gulf of Mannar in southeastern India (Neethiselvan, 2001). Sepia pharaonis Ehrenberg, 1831 Pharaoh Cuttlefish.

The western Indian Ocean clade revealed by Anderson et al. In contrast, ‘N Gulf of Oman 5’ (the specimen placed in the western Indian Ocean clade in the rhodopsin-only phylogeny) was recovered as a member of the Iranian clade in the three-gene phylogeny. Male and female adults usually die shortly after spawning and brooding, respectively. Collection locality and GenBank accession data for all specimens of Sepia pharaonis complex. Though molecular genetic data are scarce for many invertebrate fisheries in part due to the small, local scale of many such fisheries (Thorpe, Sole-Cava & Watts, 2000), several cephalopods are targets of large-scale fisheries, and population genetic studies have been published for a number of these (e.g. The initial tree topology does not seem to influence model selection, as long as the tree used is not a random topology (Posada & Crandall, 2001); neighbour joining was used only because it is a fast method to generate a ‘better-than-random’ tree. (2007) and Marshall (2010). Customise filters (scroll to see full list) Taxon. We suggest that ‘S. In short, two of our subclades correspond well to the forms described by Norman (2000), but we found that his S. pharaonis II represents at least two genetically distinct groups, and we have also found evidence for a distinct Iranian subclade. The cuttlefish isn’t a fish at all – it is a cephalopod. GenBank accession numbers for all outgroup taxa. Sepia pharaonis has also been proposed as a promising species for mariculture due to its high spawning success, rapid rate of growth, disease resistance and tolerance of crowding and handling (Minton et al., 2002; Barord, Keister & Lee, 2010).

Norman (2000) suggested that S. pharaonis comprises three forms: S. pharaonis (s. s.) (found in the western Indian Ocean from the Red Sea to the Persian Gulf; the eastern limit is unknown); S. ‘pharaonis II’ (Japan to the Gulf of Thailand, Philippines and north Australia) and S. ‘pharaonis III’ (Maldives to Andaman Sea coast of Thailand). We have also added sequence data from two specimens of Sepia ramaniNeethiselvan, 2001, collected in southeastern India. Surprisingly, it does not group with the central Indian S. pharaonis subclade; it groups with the northeastern Australia subclade, although it is quite distinct even from the latter subclade. By comparison, the rhodopsin data showed very low levels of variation. Thermal cycling regimes were as follows: 94° (1 min) – 42° (1 min) – 68° (1:30), repeated for 35 cycles, with a 7-min terminal extension step at 72° (COI); 94° (1 min) – 42° (1 min) – 72° (1:30), repeated for 35 cycles, with a 7-min terminal extension step at 72° (rhodopsin). The pharaoh cuttlefish, Sepia pharaonis (Ehrenberg 1831 1999), is distributed in tropical coastal waters in the Indo-Pacific region (Norman and Reid 2000; Nabhitabhata and Nilaphat 1999). Later, when the researchers were conducting more experiments on cuttlefish hunting, the behavior appeared again. Sign in Sign up for FREE Prices and download plans It was expertly cleaned in Vietnam, so it is all ready to use in recipes without further work, except to dismantle and cut as needed for your recipe. The deepest divergence within the S. pharaonis complex is between the western Indian Ocean clade and the rest of the complex. Data were collected from aquacultured animals using egg masses sampled from around the island and hatched in aquaria during 2010, 2011, … Unfortunately, we lack the samples from the southern or eastern Persian Gulf that would allow us to test this possibility. The pharaoh cuttlefish (Sepia pharaonis) is a large cuttlefish species that may exceed 40 cm in mantle length and 5 kg in weight. COI sequences from this study plus 16S rRNA sequences from Anderson et al., 2007) and two ‘three-gene analyses' (comprising all COI, 16S rRNA and rhodopsin sequences generated here and in Anderson et al., 2007). Cephalopod researcher Dr. James Wood sums it up well; “Octopuses, squids, cuttlefish and the chambered nautilus belong to class Cephalopoda, which means ‘head foot”. There are hints that this complex may consist of more than three species; for example, hectocotylus morphology differs between males collected in Japan and Australia (Reid et al., 2005). While mating, S. pharaonis s. s. males show zebra lines on the third arm pair, while S. pharaonis II males have broken lines and S. pharaonis III males have spots (Norman, 2000). Also known as the Cephalopod. The harmonic mean of likelihood values from the stationary phase of each analysis (calculated using the ‘sump’ command in MrBayes v. 3.1.2) was used as an estimate of the model likelihood, following Nylander et al. Login on the desktop to upload your own pictures! For the combined mtDNA dataset, all sepiids for which both COI and 16S rRNA sequences were available in GenBank were included as outgroups to provide as robust a test as possible for S. pharaonis monophyly (Table 2). This study expands on the results of Anderson et al. Our results show that Sepia ‘pharaonis’ is a complex of at least five subclades (and perhaps six, depending on the status of S. ramani). Partitioning by gene and codon resulted in four data partitions for the combined mtDNA dataset (a 16S rRNA partition and a partition for each COI codon position) and six for the three-gene dataset (16S rRNA, COI positions 1, 2 and 3, rhodopsin positions 1 + 2 and rhodopsin position 3; rhodopsin first and second codon positions were pooled due to low levels of variation). The Pharaoh Cuttlefish is found in the Mediterranean, Indo-West Pacific region growing up to 33cm in length. Ref: https://en.wikipedia.org/wiki/Pharaoh_cuttlefish. In light of this, we suggest that the binomen S. pharaonis be restricted to the western Indian Ocean subclade. The Gulf of Oman ranges from 60 km (at the Strait of Hormuz) to 370 km wide (from Ras Al Hadd, Oman to Gwadar Bay, Pakistan) and the Gulf of Oman basin is about 3,400 m deep (Uchupi, Swift & Ross, 2002). When these different estimates of sample size caused MrDT-ModSel to select different models for a given data partition, we chose the model with fewer parameters. Sepia pharaonis (pharaoh cuttlefish) is a large cuttlefish species, growing to 80 cm in mantle length. Chambered nautiluses and sepioids (Nautilidae, Sepiidae, Sepiolidae, Sepiadariidae, Idiosepiidae and Spirulidae. When the baby cuttlefish are fully developed, they can be seen 'swimming' inside the egg and already able to change colors. The rhodopsin phylogeny was poorly resolved due to the low level of variation found in this gene region among the focal taxa (tree not shown), but a monophyletic S. pharaonis comprising two subclades was recovered – one weakly supported subclade [BPP = 0.903, maximum parsimony bootstrap support (MPBS) = 53%] included all specimens collected in the Red Sea and Gulf of Aden plus one specimen (‘N Gulf of Oman 5’) collected from the Iranian coast of the Gulf of Oman, and a strongly supported subclade (BPP = 0.990, MPBS = 93%) comprising all other S. pharaonis and S. ramani individuals. Species: S. pharaonis. Western Indian Ocean Journal of Marine Science, MrBayes 3: Bayesian phylogenetic inference under mixed models, The monsoon circulation of the Indian Ocean. Widespread Mediterranean, Indo-West Pacific There is generally little evidence of migration of cuttlefish between geographic regions in our data. Ten such analyses were run, with bootstrap support values for each node averaged across all 10 runs. əl‚fish] (invertebrate zoology) An Old World decapod mollusk of the genus Sepia; shells are used to manufacture dentifrices and cosmetics. (2007) noted, the type localities of S. pharaonis are both in the Red Sea (near El-Tor in the Sinai in the northern Red Sea and near Massawa in Eritrea along the west coast of the Red Sea).

Sepia pharaonis is a commercially harvested species, and it is a significant component of cephalopod fisheries throughout its range (Nesis, 1987; Reid, Jereb & Roper, 2005). The number of parameters, run length (‘length’) in millions of generations, best-fitting models, and AICc and BIC values for different partitioning schemes for the combined mtDNA (16S rRNA + COI) and three-gene (16S rRNA + COI + rhodopsin) datasets. Only 10 of 523 sites for rhodopsin were variable within S. pharaonis (all but one of these sites were at the third codon position) and only seven of these sites were parsimony-informative. The combined mtDNA phylogeny is shown in Figure 2. (2010). Appropriate partitioning schemes for the two multigene datasets were chosen using the AICc (a second-order correction of the Akaike Information Criterion) and the Bayesian Information Criterion (BIC), following McGuire et al. Tissue samples from two additional specimens of S. pharaonis and two specimens of S. ramani were collected in Tuticorin, India, in October 2007. This finding was foreshadowed by Reid et al. Pharaoh Cuttlefish: This is a large species of cuttlefish that inhabits the Pacific region between Japan and Australia and as far west as the Red Sea. Video by Japan Ethological Society & Springer Japan. Fifty per cent majority-rule consensus Bayesian phylogram for the combined three-gene (COI + 16S rRNA + rhodopsin) dataset for the Sepia pharaonis complex. (2005), who noted that hectocotylus morphology differs between S. pharaonis specimens from Japan (presumably members of our western Pacific subclade, though it is possible that Japan is home to yet another S. pharaonis subclade) and Australia. FAO Species Catalogue for Fishery Purposes, Food and Agricultural Organization of the United Nations, Comparative phylogeography and species boundaries in. Have a photo you want identified? Members of the class Cephalopoda are gonochoric. Partition abbreviations are as follows: C, COI; R, rhodopsin; C1, COI position 1; C2, COI position 2; C3, COI position 3; R12, rhodopsin position 1 + position 2; R3, rhodopsin position 3. This specimen could be misidentified, or it could be a hybrid (or backcross) between S. ramani and S. pharaonis that exhibits S. ramani morphology but carries a S. pharaonis mtDNA haplotype. For each dataset or partition, models were evaluated by using all sites or only variable sites as estimates of sample size (Posada & Buckley, 2004). Mong-Fong Lee, Chun-Yen Lin, Chuan-Chin Chiao, and Chung-Cheng Lu (2016) The pharaoh cuttlefish, Sepia pharaonis, is one of the most important cephalopod fishery species in southeastern Asia. (2007) found that S. pharaonis comprises five distinct clades: a western Indian Ocean clade (Gulf of Aden and Red Sea), a northeastern Australia clade, an Iranian clade (northern Gulf of Oman and the Persian Gulf), a central Indian Ocean clade (India and the Andaman Sea coast of Thailand) and a western Pacific clade. Sometimes the boys of these cephalopods will fight each other over a girl they like, but they won't touch each other, they just flash different patterns of colors. To clarify these relationships, we have sequenced an additional mitochondrial gene region (cytochrome oxidase subunit I) and a nuclear gene region (rhodopsin) from over 50 specimens from throughout the range of S. pharaonis. Oxford University Press is a department of the University of Oxford. πία, sēpía, cuttlefish. Reid et al. Males can only produce once and the females die shortly after laying their eggs. For both the combined mtDNA dataset and the three-gene dataset, the AICc and BIC values were lowest for the ‘by gene and codon position’ partitioning scheme, indicating that this was the best-fitting partitioning scheme of those evaluated for these data (Table 3). 5 kg, and for females 50 cm and 2 kg in … Such data could be particularly important for S. pharaonis. Pharaoh Cuttlefish (Sepia pharaonis) is also known as the Large Striped Cuttlefish and Seiche Pharaon. They usually … Upload them now! πία, sēpía, cuttlefish. Customise filters × Customise filters (scroll to see full list) (scroll to see full list) The Pharaoh cuttlefish ranks high among the fish export list from Oman. Codes in parentheses refer to original studies (B, Bellingham, Morris & Hunt, 1998; Murphy, J.M., Hernandez, M.N., Pereles-Raya, C. and Balguerias, E. Furthermore, within the Indian Ocean, archipelagos with extensive reef systems such as Seychelles, Mauritius and the Maldives also seem to have been sampled more frequently than the continental shelves of south Asia and northeastern Africa. From FishBase, you are looking for information on human uses of the species 'Sepia pharaonis'. Found in shallow waters over sand and seagrass beds of coral and rocky reefs. Crandall et al. Though we did not obtain samples from the type localities, we did obtain samples from the Yemeni Red Sea coast (340 km east of Massawa) and found that these specimens were members of our western Indian Ocean subclade. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Alignment of the COI and rhodopsin sequences was performed by eye in Se-Al v. 2.0a11 (Rambaut, 2002). It is possible that Pleistocene glaciations also played a role in the divergence between the central Indian Ocean and western Pacific clades of S. pharaonis, though the current lack of divergence time information for the S. pharaonis complex limits our ability to test hypotheses of causality. However, currents might facilitate rare dispersal events across the Gulf of Oman at certain times of the year. FYI: Shown here only for identification only. To avoid these problems, analyses were performed with the temperature set to 0.05 (which resulted in state-swap frequencies of 60–70%) and the branch-length prior mean was reduced to 0.02 using the command ‘brlens = unconstrained:Exp[50.0]’, following the recommendations of McGuire et al. Sepia pharaonis. (2007): 1, Red Sea; 2, Gulf of Aden; 3, Persian Gulf (Iran); 4, northern Gulf of Oman (Iran); 5, southern Gulf of Oman (Oman); 6, Veraval; 7, Kochi; 8, Tuticorin; 9, Vishakapatanam; 10, Phuket; 11, Prachuap; 12, Chumphon; 13, Taiwan; 14, Gulf of Carpentaria; 15, northeast Queensland. Sequence data for all outgroups were downloaded from GenBank. Neethiselvan (2001) noted that S. ramani is difficult to distinguish from S. pharaonis, although he listed some characters that allow the two species to be identified: S. ramani has 5–6 enlarged club suckers, with 3–4 greatly enlarged, whereas S. pharaonis has 15–24 enlarged suckers, all of approximately equal size; and there are 14–16 transverse rows of normal suckers on the hectocotylus of S. ramani, but only 10–12 such rows in S. pharaonis. Flamboyant Cuttlefish: This species is well-named for the rather bright and exuberant pattern of colors on … Numbers above branches are clade posterior probability (BPP) estimates; numbers below branches are MPBS values. Furthermore, additional specimens from as-yet-unsampled parts of the range of the S. pharaonis complex must be evaluated, as there may be additional subclades (or species) waiting to be discovered; regions of particular interest are Madagascar, the Philippines, the Yellow Sea (Hwang Hai) and Indonesia. This investigation of S. pharaonis phylogeography may shed some light on biogeographic patterns of neritic animals in the Indian Ocean and western Pacific. PCRs were performed using a Perkin-Elmer 9700 thermal cycler. Sperm … Size: 18 inches (45 cm) ... Genus: Sepia. One group of closely related individuals (the central Indian Ocean subclade) is distributed across the central Indian Ocean along the east and west coasts of India and the Andaman Sea coast of Thailand; in contrast, another group seems to be restricted to the Persian Gulf and northern Gulf of Oman (the Iranian subclade). A rate multiplier was used for all partitioned analyses (the rate multiplier associates substitution rates for different partitions with a Dirichlet prior to allow different rates across partitions). Conversely, phylogenetic patterns may be concordant across taxa, but these similarities could be due to pseudocongruence, in which similar phylogenetic patterns arise among two or more taxa of different ages that were affected by different vicariant events (Cunningham & Collins, 1994; Donoghue & Moore, 2003). We generated a total of 46 COI sequences and 43 rhodopsin sequences (Table 1). Tissue samples were collected from Sepia pharaonis individuals from throughout the range of the species (Table 1, Fig. Pharaoh Cuttlefish We just learned about the Humboldt Squid. They have eight short arms and two long tentacles that are usually tucked neatly into their arms. Parts of a sepia. (2007) and using equations listed in Posada & Buckley (2004). Furthermore, the semelparous annual life cycle of many cephalopods (probably including S. pharaonis; Gabr et al., 1998, but see Aoyama & Nguyen, 1989) makes their stocks highly vulnerable to overexploitation (Thorpe et al., 2000). This subclade is sister to a clade comprising all other subclades in the complex (including S. ramani; Fig. One of the S. ramani specimens is nested within the central Indian Ocean clade, but the other is sister to the Australia clade. Estimated Bayesian posterior probabilities (BPPs) of clades on inferred trees were interpreted as measures of support. Differences in phylogeographic patterns across studies of Indo-Pacific neritic taxa are not surprising, given the substantial differences in life history, ecology and behaviour among these taxa. There appear to be consistent reproductive differences among these three forms. Prices and download plans . DNA extraction, PCR product purification, automated DNA sequencing and sequence editing were as described in Anderson et al. Sepia ramani is a neritic demersal southeastern Indian species that is morphologically very similar to S. pharaonis, and there has been some controversy regarding the status of S. ramani as a distinct species. In light of this, we believe that specimens from the type localities would probably be members of our western Indian Ocean subclade. *Rerun for 50 million generations. Mating behavior: Males perform various displays to attract potential females for copulation. (2007) based on partial mitochondrial 16S rRNA sequence data collected from S. pharaonis samples from throughout the Indian Ocean and western Pacific Ocean. The cuttlefish's flat body allows it to live and hover near the ocean bottom where it finds its favorite food. (2008) found that phylogeographic patterns can differ substantially between sympatric species, even when those species are congeneric and ecologically similar. (2004). Sepia pharaonis shows considerable morphological and behavioural variation across its range, leading Norman (2000) to suggest that S. pharaonis s. l. consists of three forms: S. pharaonis s. s. (Red Sea to the Gulf of Oman, including the Persian Gulf), Sepia pharaonis II (western Pacific and northern Australia) and S. pharaonis III (Maldives to the Andaman Sea coast of Thailand). McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. Like all cuttlefish, they are incredibly intelligent and Pharaoh Cuttlefish (Sepia pharaonis) - Marine Life - Liveaboard Diving All hope is not lost, however, because sepiids possess a calcified structure that would seemingly be amenable to fossilization – the cuttlebone. Despite this bias, there are several phylogeographic studies whose focal taxa are found in many of the same regions where S. pharaonis is found, and comparisons with these studies may be fruitful. The tentacles are deployed to catch prey. Sepia Temporal range: Miocene – Recent PreꞒ Ꞓ O S D C P T J K Pg N … Finally, it must be noted that representatives of only 14 sepiid species were used as outgroups in this study. (2007), however, in recovering moderate support for monophyly of the Sepia pharaonis complex, including a previously unsampled species (S. ramani), and in clarifying relationships among these five clades. Cuttlefish gather in their hundreds of thousands to spawn. In analyses of the partitioned datasets, all model parameters except topology and branch lengths were unlinked across partitions. Recovery of cuttlebones attributable to the S. pharaonis complex might allow estimation of the age of the complex and divergence times within the complex, allowing phylogeographic comparisons of S. pharaonis with other neritic species in the Indian Ocean. 49, Paris, France, DNA primers for amplification of mitochondrial cytochrome c oxidase subunit I from diverse metazoan invertebrates, Molecular Marine Biology and Biotechnology. pharaonis’ may consist of several species, but morphological work is needed to clarify species-level taxonomy within this complex. In contrast to analyses of the combined mtDNA data alone, the three-gene dataset gives some support for monophyly of the S. pharaonis complex (BPP = 0.70, MPBS = 81%) and a close relationship among the Iranian clade, the western Pacific clade and the central Indian Ocean clade (BPP = 0.96, MPBS = 93%). Upload image Search results from the FishSource database for all stocks and fisheries for this species are available after dismissing this dialog. Genus: Sepia . The three-gene phylogeny is shown in Figure 3. N Gulf of Oman 3* grouped strongly with the western Indian Ocean subclade on all phylogenies, while N Gulf of Oman 5 grouped with the Iranian subclade (as expected) in the mtDNA and three-gene phylogenies (Figs 2, 3), but with the western Indian Ocean subclade on the rhodopsin phylogeny. Another type of cephalopod is the Pharaoh Cuttlefish. However, the main spawning season for S. pharaonis in this region is November and December, between the monsoons (Reid et al., 2005) and after the Ras Al Hadd jet has weakened. When this value reached 0.01, the runs were terminated. genetically, the range of this form extends north and west of the Maldives along the Indian coast).

During the southwestern (summer) monsoon, the Ras Al Hadd jet (a continuation of the Somali and Oman Coastal Currents that flows eastward from the eastern tip of Oman; Schott & McCreary, 2001) and the cyclonic eddy it produces in the Gulf of Oman could promote occasional dispersal of S. pharaonis juveniles across the Gulf. Colour changes to match surroundings. πία, sēpía, cuttlefish. Found in shallow waters over sand and seagrass beds of coral and rocky reefs. Sepia ramani is a member of the S. pharaonis species complex, though one of our S. ramani samples may represent an additional, previously unsampled subclade within the complex. COI and rhodopsin sequences obtained in this study were combined with all available sepiid 16S rRNA, COI and rhodopsin sequences in GenBank (http://www.ncbi.nlm.nih.gov/) as of 17 February 2009. Sepia. ramani’ weakly supported as sister to this clade), an Iranian clade (northeastern Persian Gulf and northern Gulf of Oman), a western Pacific clade and a broadly distributed central Indian Ocean clade (west and east coasts of India and the Andaman Sea coast of Thailand). Ref: https://en.wikipedia.org/wiki/Pharaoh_cuttlefish, Length: 33cm Depth: 0-130m Found: Mediterranean, Indo-West Pacific Eats: crustaceans, fish Family: Cuttlefishes Scientific Family: Sepiidae. Recovery of a sister pair consisting of the Western Pacific clade and the Central Indian Ocean clade in the S. pharaonis complex, though weakly supported (BPP = 0.94, MPBS < 50%), is consistent with numerous other studies that have found similar sister species or population pairs, with one species (or population) in the Indian Ocean and the other in the Pacific Ocean (Williams et al., 2002 and citations therein; Reid et al., 2006). It is commonly hunted in the Philippines, India, and Persia for food. Although our data do not allow us to determine the precise location of boundaries between phylogeographic units, it is clear that the regions where different clades are found differ substantially in size. A total of 141 out of 684 sites for COI were variable and 109 of these were parsimony-informative within Sepia pharaonis. Only nodes with BPP > 0.90 and/or MPBS > 70% have values associated with them, and support values within geographically delimited clades are not shown. These likelihood scores were used to select a best-fitting substitution model using ‘MrDT-ModSel’, a modification of DT-ModSel (Minin et al., 2003) developed by F.E.A. Human food fish. (2007) and confirmed here corresponds quite well to Norman's S. pharaonis s. s., although we found evidence of a genetic break between the southern and northern Gulf of Oman (see below). The geographic regions in question are adjacent to one another; one member of the western Indian Ocean subclade (S Gulf of Oman 1) was collected from the southern coast of the Gulf of Oman, while the Iranian specimens (N Gulf of Oman 2, 3, 4 and 5) were collected about 230 km to the northeast, on the opposite side of the Gulf of Oman.
