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 A muscular hood on the dorsal side helps close the aperture when the animal is withdrawn into the shell.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. -

First Records and Descriptions of Early-Life Stages of Cephalopods from Rapa Nui (Easter Island) and the Nearby Apolo Seamount
First records and descriptions of early-life stages of cephalopods from Rapa Nui (Easter Island) and the nearby Apolo Seamount By Sergio A. Carrasco*, Erika Meerhoff, Beatriz Yannicelly, and Christian M. Ibáñez Abstract New records of early-life stages of cephalopods are presented based on planktonic collections carried out around Easter Island (Rapa Nui; 27°7′S; 109°21′W) and at the nearby Apolo Seamount (located at ∼7 nautical miles southwest from Easter Island) during March and September 2015 and March 2016. A total of thirteen individuals were collected, comprising four families (Octopodidae, Ommastrephidae, Chtenopterygidae, and Enoploteuthidae) and five potential genera/types (Octopus sp., Chtenopteryx sp., rhynchoteuthion paralarvae, and two undetermined Enoploteuthid paralarvae). Cephalopod mantle lengths (ML) ranged from 0.8 to 4.5 mm, with 65% of them (mainly Octopodidae) corresponding to newly hatched paralarvae of ~1 mm ML, and 35% to rhynchoteuthion and early stages of oceanic squids of around 1.5 - 4.5 mm ML. These results provide the first records on composition and presence of early stages of cephalopods around a remote Chilean Pacific Island, while also providing a morphological and molecular basis to validate the identity of Octopus rapanui (but not Callistoctopus, as currently recorded), Ommastrephes bartramii and Chtenopteryx sp. around Rapa Nui waters. Despite adult Octopodidae and Ommastrephidae have been previously recorded at these latitudes, the current findings provide evidence to suggest that the northwest side of Easter Island, and one of the nearby seamounts, may provide a suitable spawning ground for benthic and pelagic species of cephalopods inhabiting these areas. For Chtenopterygidae and Enoploteuthidae, this is the first record for the Rapa Nui ecoregion. -

This group includes experimental analysis from the first cell division through to the many species that can potentially be used as models in the fields of formation of embryonic germ layers and organogenesis (Boletzky biomedicine, developmental biology, evolution, neuroscience and et al., 2006). Finally, small embryos allow reasonable sample sizes even for robotics research. The purpose of this work is to first to be tested together using multi-well plates to provide multiple present a simple method for maintaining Octopus insularis embryos experimental replicates at the same time, making them cost- under a laboratory setup. Second, we show that these embryos are effective animal models (Hill et al., 2005). suitable for detailed analyses of specific traits that appear during Coleoid cephalopods (octopus, squid and cuttlefish) exhibit the developmental stages, including the eyes, hearts, arms, suckers, largest nervous systems found among invertebrates (Young, 1971) chromatophores and Kölliker’s organs.

Conids are well known for being active predators on worms, fishes, and even other snails. Cones are venomous gastropods, meaning that they use a sophisticated cocktail of hundreds of toxins, named conotoxins, to subdue their prey. Although this venom has been studied for decades, most of the effort has been focused on Indo-Pacific species. Thus far, Atlantic species have received little attention despite recent radiations have led to a hotspot of diversity in West Africa, with high levels of endemic species. In fact, the Atlantic Chelyconus ermineus is thought to represent an adaptation to piscivory independent from the Indo-Pacific species and is, therefore, key to understanding the basis of this diet specialization. We studied the transcriptomes of the venom gland of three individuals of C. ermineus. The venom repertoire of this species included more than 300 conotoxin precursors, which could be ascribed to 33 known and 22 new (unassigned) protein superfamilies, respectively. Most abundant superfamilies were T, W, O1, M, O2, and Z, accounting for 57% of all detected diversity. -
