INTRODUCTION Although there are 845 living species of cephalopod described to date (Hoving et al., 2015), including nautiloids, sepioids, squids and octopods, only the latter elicit a vast amount of interest and awe from the general public. Octopuses are often seen as mystical creatures, capable of escapes from captivity that Houdini could only dream of (Wood and Anderson, 2004) and, to some, able to predict the winner of some matches in the FIFA World Cup football competition (as mentioned, for example, by Gleadall et al., 2018). About 300 cephalopod species belong to the eight-armed cephalopods comprising the orders Cirroctopoda and Octopoda (Boletzky, 1999; Nixon and Young, 2003). The Cirroctopoda (which are not part of the octopus fishery) have fins on the body and pairs of slender cirri along the arms. Octopuses of the Order Octopoda lack these features and consist of seven families of pelagic octopuses in addition to the common benthic octopuses, which are a group of around 200 described species comprising the Family Octopodidae (Jereb et al., 2013). Almost all octopuses fished around the world belong to this family. Exceptions are the giant octopuses of genus Enteroctopus (Family Enteroctopodidae); and octopuses with a single column of suckers along each arm, comprising the genus Eledone (Family Eledonidae sensu Strugnell et al., 2014). Adult benthic octopuses (Octopodidae, Eledonidae and Enteroctopodidae), the subject of this review, are muscular animals with one or two columns of suckers along their four pairs of arms. In mature males, one arm (called the hectocotylus) of the third arm pair is modified for transferring spermatophores to the female. Subadult and adult benthic octopuses live and feed on or near the seabed and possess ecological and behavioural features that are quite similar to benthic fishes (ref.? ). For locomotion, octopuses walk using all or some of their arms in contact with the substrate. Like many other cephalopods, they swim using jet propulsion, by contracting their muscular mantle to force water in the mantle cavity out through a tubular funnel. Octopuses have a well-developed brain and nervous system which regulate sophisticated behaviour and learning, and control elaborate, dynamic skin patterns (Hanlon and Messenger, 1996; How et al., 2017). The internal shell is reduced to a pair of small rod-like stylets. These stylets have been used to estimate age by counting their daily growth increments, a technique that has been validated for some coastal species (Doubleday et al., 2006; Hermosilla et al., 2010; Rodríguez-Domínguez et al., 2013). Growth increments in beaks also have been used to estimate age in octopuses (Perales-Raya et al., 2014; Villegas-Bárcenas et al., 2014).

  • Genetic Identification of Octopodidae Species in Southern California Seafood Markets: Species Diversity and Resource Implications
    Genetic Identification of Octopodidae Species in Southern California Seafood Markets: Species Diversity and Resource Implications Chase Martin Center for Marine Biodiversity and Conservation Scripps Institution of Oceanography University of California San Diego Abstract Various species of Octopodidae are commonly found in seafood markets throughout Southern California. Most of the octopus available for purchase is imported, with the majority of imports coming from various Asian nations. Despite the diversity of global octopus species, products are most commonly labeled as simply “octopus,” with some distinctions being made in size, e.g., “baby” or “little octopus.” In efforts to characterize species diversity, this study genetically tested 59 octopus samples from a variety of seafood markets in Los Angeles, Orange, and San Diego Counties. Universal 16S rRNA primers (ref) and CO1 primers developed by Folmer et al. (1994) were used for PCR amplification and sequencing of mtDNA. In all, 105 sequences were acquired. Seven species were identified with some confidence. Amphioctopus aegina was the most prevalent species, while two additional species were undetermined. Little available data exists pertaining to octopus fisheries of the countries of production of the samples. Most available information on octopus fisheries pertains to those of Mediterranean and North African nations, and identifies the Octopus vulgaris as the fished species. Characterizing octopus diversity in Southern California seafood markets and assessing labeling and countries of production provides the necessary first step for assessing the possible management implications of these fisheries and seafood supply chain logistics for this group of cephalopods. Introduction Octopuses are exclusively marine cephalopod mollusks that form the order Octopoda.

Res. 12 (3): 3755-3765 (2013) Received January 21, 2013 Accepted August 20, 2013 Published September 19, 2013 DOI http://dx.doi.org/10.4238/2013.September.19.7 ABSTRACT. Octopus in the family Octopodidae (Mollusca: Cephalopoda) has been generally recognized as a “catch-all” genus. The monophyly of octopus species in China’s coastal waters has not yet been studied. In this paper, we inferred the phylogeny of 11 octopus species (family Octopodidae) in China’s coastal waters using nucleotide sequences of two mitochondrial DNA genes: cytochrome c oxidase subunit I (COI) and 16S rRNA. Sequence analysis of both genes revealed that the 11 species of Octopodidae fell into four distinct groups, which were genetically distant from one another and exhibited identical phylogenetic resolution. The phylogenies indicated strongly that the genus Octopus in China’s coastal waters is also not monophyletic, and it is therefore clear that the Octopodidae systematics in this area requires major revision. It is demonstrated that partial sequence information of both the mitochondrial genes 16S rRNA and COI could be used as diagnostic molecular markers in the identification and resolution of the taxonomic ambiguity of Octopodidae species.

  • The Occurrence of Cistopus Taiwanicus in Sri Lankan Waters
    Proceedings of the National Aquatic Resources Research and Development Agency (NARA), Scientific Sessions 2016 The occurrence of Cistopus taiwanicus in Sri Lankan waters D.R. Herath*, D.N.A. Ranmadugala and A.A.D.G.U. Amarakoon Marine Biological Resources Division, National Aquatic Resources Research and Development Agency (NARA), Crow Island, Colombo 15, Sri Lanka Abstract Cephalopods include a diverse collection of more than 650 species of octopus, cuttlefish, squid and nautilus. Several of these species are commercially important in Sri Lanka. As morphological identification is sometimes difficult, molecular techniques were used to confirm the species of cuttlefish, squid and octopus species found in Sri Lankan waters. Cephalopod samples were collected from Chilaw, Negombo, Beruwela and Kalpitiya. The miotochondrial COI region was amplified and sequenced. The sequences were matched with universal databases to identify each species. The cuttlefish species Sepia aculeata, Sepiella inermis, Sepia pharaonis and Sepioteuthis lessoniana, the squid species,' Loligo singhalensis and Loligo (Uroteuthis) duvacelli were identified by this barcoding technique. Two species of octopus,Cistopus taiwanicusaad Octopus vulgaris were also identified. A significant finding in this study was that two separate octopus specimens collected from Negombo and Kalpitiya were identified as Cistopus taiwanicus. Four species of Cistopus, namely, C indicus, C. chinensis, C. taiwanicus and C. platinoidus have been recorded in the world. Out of these four species, only C. indicus has been reported from Sri Lanka. Therefore, the species list for Cephalopod species precent in Sri Lanka could be updated to include the species Cistopus taiwanicus. Further research is needed to confirm whether C. indicus and C.

    Arctic cephalopod distributions and their associated predatorspor_146 209..227 Kathleen Gardiner & Terry A. Dick Biological Sciences, University of Manitoba, Winnipeg, Manitoba R3T 2N2, Canada Keywords Abstract Arctic Ocean; Canada; cephalopods; distributions; oceanography; predators. Cephalopods are key species of the eastern Arctic marine food web, both as prey and predator. Their presence in the diets of Arctic fish, birds and mammals Correspondence illustrates their trophic importance. There has been considerable research on Terry A. Dick, Biological Sciences, University cephalopods (primarily Gonatus fabricii) from the north Atlantic and the west of Manitoba, Winnipeg, Manitoba R3T 2N2, side of Greenland, where they are considered a potential fishery and are taken Canada. E-mail: [email protected] as a by-catch. By contrast, data on the biogeography of Arctic cephalopods are doi:10.1111/j.1751-8369.2010.00146.x still incomplete. This study integrates most known locations of Arctic cepha- lopods in an attempt to locate potential areas of interest for cephalopods, and the predators that feed on them. International and national databases, museum collections, government reports, published articles and personal communica- tions were used to develop distribution maps. Species common to the Canadian Arctic include: G. fabricii, Rossia moelleri, R. palpebrosa and Bathypolypus arcticus. Cirroteuthis muelleri is abundant in the waters off Alaska, Davis Strait and Baffin Bay. Although distribution data are still incomplete, groupings of cephalopods were found in some areas that may be correlated with oceanographic variables. Understanding species distributions and their interactions within the ecosys- tem is important to the study of a warming Arctic Ocean and the selection of marine protected areas.
