CEPHALOPODS 688 Cephalopods
click for previous page CEPHALOPODS 688 Cephalopods Introduction and GeneralINTRODUCTION Remarks AND GENERAL REMARKS by M.C. Dunning, M.D. Norman, and A.L. Reid iving cephalopods include nautiluses, bobtail and bottle squids, pygmy cuttlefishes, cuttlefishes, Lsquids, and octopuses. While they may not be as diverse a group as other molluscs or as the bony fishes in terms of number of species (about 600 cephalopod species described worldwide), they are very abundant and some reach large sizes. Hence they are of considerable ecological and commercial fisheries importance globally and in the Western Central Pacific. Remarks on MajorREMARKS Groups of CommercialON MAJOR Importance GROUPS OF COMMERCIAL IMPORTANCE Nautiluses (Family Nautilidae) Nautiluses are the only living cephalopods with an external shell throughout their life cycle. This shell is divided into chambers by a large number of septae and provides buoyancy to the animal. The animal is housed in the newest chamber. A muscular hood on the dorsal side helps close the aperture when the animal is withdrawn into the shell. Nautiluses have primitive eyes filled with seawater and without lenses. They have arms that are whip-like tentacles arranged in a double crown surrounding the mouth. Although they have no suckers on these arms, mucus associated with them is adherent. Nautiluses are restricted to deeper continental shelf and slope waters of the Indo-West Pacific and are caught by artisanal fishers using baited traps set on the bottom. The flesh is used for food and the shell for the souvenir trade. Specimens are also caught for live export for use in home aquaria and for research purposes. -

BOX; 1408, Lattakia, Syria [email protected] (corresponding author); [email protected]; [email protected]; [email protected]; [email protected] ABSTRACT Syria’s total marine fisheries catches were estimated for the 1950-2010 time period using a reconstruction approach which accounted for all fisheries removals, including unreported commercial landings, discards, and recreational and subsistence catches. All unreported estimates were added to the official data, as reported by the Syrian Arab Republic to the United Nation’s Food and Agriculture Organization (FAO). Total reconstructed catch for 1950-2010 was around 170,000 t, which is 78% more than the amount reported by Syria to the FAO as their national catch. The unreported components added over 74,000 t of unreported catches, of which 38,600 t were artisanal landings, 16,000 t industrial landings, over 4,000 t recreational catches, 3,000 t subsistence catches and around 12,000 t were discards. -

Caribbean Reef Squid)
UWI The Online Guide to the Animals of Trinidad and Tobago Ecology Sepioteuthis sepioidea (Caribbean Reef Squid) Order: Teuthida (Squid) Class: Cephalopoda (Octopuses, Squid and Cuttlefish) Phylum: Mollusca (Molluscs) Fig. 1. Caribbean reef squid, Sepioteuthis sepioidea. [http://www.arkive.org/caribbean-reef-squid/sepioteuthis-sepioidea/image-G76785.html, downloaded 10 March 2016] TRAITS. The mantle (body mass) is wide and relatively flattened, with a length of 114mm in adult males and 120 mm in adult females (Moynihan and Rodaniche, 1982). A skeleton is absent but a cartilaginous layer is normally found beneath the surface of the mantle which enables movement (Mather et al., 2010).Two fins span the length of the lateral mantle margins (Fig. 1). The head is slightly pointed to its anterior end, with eight arms and two tentacles which encircle the mouth (Mather et al., 2010). Suckers are positioned along the inner region of arms and tentacle clubs. The mantle is fleshy when relaxed and the skin is very fragile (Moynihan and Rodaniche, 1982). The colour patterns of the skin can change periodically, due to the existence of light-reflective and iridescence-inducing cells (Mather, 2010). DISTRIBUTION. Distributed throughout the West Indian islands, including Trinidad and Tobago; widespread along the Central and South American coasts adjacent to the Caribbean Sea and also found in Bermuda and Florida (Moynihan and Rodaniche, 1982). UWI The Online Guide to the Animals of Trinidad and Tobago Ecology HABITAT AND ACTIVITY. Found in highly saline, clear waters of marine habitats at varying depths and distances from shoreline (Wood et al., 2008). The depth and habitat they are observed at depends on their growth stage (Mather et al., 2010). -

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. -

Os Nomes Galegos Dos Moluscos
A Chave Os nomes galegos dos moluscos 2017 Citación recomendada / Recommended citation: A Chave (2017): Nomes galegos dos moluscos recomendados pola Chave. http://www.achave.gal/wp-content/uploads/achave_osnomesgalegosdos_moluscos.pdf 1 Notas introdutorias O que contén este documento Neste documento fornécense denominacións para as especies de moluscos galegos (e) ou europeos, e tamén para algunhas das especies exóticas máis coñecidas (xeralmente no ámbito divulgativo, por causa do seu interese científico ou económico, ou por seren moi comúns noutras áreas xeográficas). En total, achéganse nomes galegos para 534 especies de moluscos. A estrutura En primeiro lugar preséntase unha clasificación taxonómica que considera as clases, ordes, superfamilias e familias de moluscos. Aquí apúntase, de maneira xeral, os nomes dos moluscos que hai en cada familia. A seguir vén o corpo do documento, onde se indica, especie por especie, alén do nome científico, os nomes galegos e ingleses de cada molusco (nalgún caso, tamén, o nome xenérico para un grupo deles). Ao final inclúese unha listaxe de referencias bibliográficas que foron utilizadas para a elaboración do presente documento. Nalgunhas desas referencias recolléronse ou propuxéronse nomes galegos para os moluscos, quer xenéricos quer específicos. Outras referencias achegan nomes para os moluscos noutras linguas, que tamén foron tidos en conta. Alén diso, inclúense algunhas fontes básicas a respecto da metodoloxía e dos criterios terminolóxicos empregados. 2 Tratamento terminolóxico De modo moi resumido, traballouse nas seguintes liñas e cos seguintes criterios: En primeiro lugar, aprofundouse no acervo lingüístico galego. A respecto dos nomes dos moluscos, a lingua galega é riquísima e dispomos dunha chea de nomes, tanto específicos (que designan un único animal) como xenéricos (que designan varios animais parecidos). -
Octopus Consciousness: the Role of Perceptual Richness
Review Octopus Consciousness: The Role of Perceptual Richness Jennifer Mather Department of Psychology, University of Lethbridge, Lethbridge, AB T1K 3M4, Canada; [email protected] Abstract: It is always difficult to even advance possible dimensions of consciousness, but Birch et al., 2020 have suggested four possible dimensions and this review discusses the first, perceptual richness, with relation to octopuses. They advance acuity, bandwidth, and categorization power as possible components. It is first necessary to realize that sensory richness does not automatically lead to perceptual richness and this capacity may not be accessed by consciousness. Octopuses do not discriminate light wavelength frequency (color) but rather its plane of polarization, a dimension that we do not understand. Their eyes are laterally placed on the head, leading to monocular vision and head movements that give a sequential rather than simultaneous view of items, possibly consciously planned. Details of control of the rich sensorimotor system of the arms, with 3/5 of the neurons of the nervous system, may normally not be accessed to the brain and thus to consciousness. The chromatophore-based skin appearance system is likely open loop, and not available to the octopus’ vision. Conversely, in a laboratory situation that is not ecologically valid for the octopus, learning about shapes and extents of visual figures was extensive and flexible, likely consciously planned. Similarly, octopuses’ local place in and navigation around space can be guided by light polarization plane and visual landmark location and is learned and monitored. The complex array of chemical cues delivered by water and on surfaces does not fit neatly into the components above and has barely been tested but might easily be described as perceptually rich.
