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 A muscular hood on the dorsal side helps close the aperture when the animal is withdrawn into the shell.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

Quantifying Morphological Variability Through the Latest Ontogeny Of
QUANTIFYING MORPHOLOGICAL VARIABILITY THROUGH THE LATEST ONTOGENY OF HOPLOSCAPHITES (JELETZKYTES) FROM THE LATE CRETACEOUS WESTERN INTERIOR USING GEOGRAPHIC INFORMATION SYSTEMS AS A MORPHOMETRIC TOOL Mathew J. Knauss A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE August 2013 Committee: Margaret M. Yacobucci, Advisor Enrique Gomezdelcampo Sheila Roberts © 2013 Mathew J. Knauss All Rights Reserved iii ABSTRACT Margaret M. Yacobucci, Advisor Ammonoids are known for their intraspecific and interspecific morphological variation through ontogeny, particularly in shell shape and ornamentation. Many shell features covary and individual shell elements (e.g., tubercles, ribs, etc.) are difficult to homologize, which make qualitative descriptions and widely-used morphometric tools inappropriate for quantifying these complex morphologies. However, spatial analyses such as those applied in geographic information systems (GIS) allow for quantification and visualization of global shell form. Here, I present a GIS-based methodology in which the variability of complex shell features is assessed in order to evaluate evolutionary patterns in a Cretaceous ammonoid clade. I applied GIS-based techniques to sister species from the Late Cretaceous Western Interior Seaway: the ancestral and more variable Hoploscaphites spedeni, and descendant and less variable H. nebrascensis. I created digital models exhibiting the shells’ lateral surfaces using photogrammetric software and imported the reconstructions into a GIS environment. I used the number of discrete aspect patches and the 3D to 2D area ratios of the lateral surface as terrain roughness indices. These 3D analyses exposed the overlapping morphological ranges of H. spedeni and H. -

Original Article Fish Aquat Sci 15(3), 197-202, 2012 Endoprotease and Exopeptidase Activities in the Hepatopancreas of the Cuttlefish Sepia officinalis, the Squid Todarodes pacificus, and the Octopus Octopus vulgaris Cuvier Min Ji Kim1, Hyeon Jeong Kim1, Ki Hyun Kim1, Min Soo Heu2 and Jin-Soo Kim1* 1Department of Seafood Science and Technology/Institute of Marine Industry, Gyeongsang National University, Tongyeong 650-160, Korea 2Department of Food Science and Nutrition/Institute of Marine Industry, Gyeongsang National University, Jinju 660-701, Korea Abstract This study examined and compared the exopeptidase and endoprotease activities of the hepatopancreas (HP) of cuttlefish, squid, and octopus species. The protein concentration in crude extract (CE) from octopus HP was 3,940 mg/100 g, lower than those in CEs from squid HP (4,157 mg/100 g) and cuttlefish HP (5,940 mg/100 g). With azocasein of pH 6 as a substrate, the total activity in HP CE of octopus was 31,000 U, lower than the values for cuttlefish (57,000 U) and squid (69,000 U). Regardless of sample type, the total activities of the CEs with azocasein as the substrate were higher at pH 6 (31,000–69,000 U) than at pH 9 (19,000–34,000 U). With L-leucine-p-nitroanilide (LeuPNA) of pH 6 as the substrate, the total activity of the HP CE from octopus was 138,000 U, higher than values from both cuttlefish HP (72,000 U) and squid HP (63,000 U). Regardless of sample type, the total activities of the CEs with LeuPNA as the substrate were higher at pH 6 (63,000–138,000 U) than at pH 9 (41,000–122,000 U). -

Cephalopod Reproductive Strategies Derived from Embryonic Shell Size
Biol. Rev. (2017), pp. 000–000. 1 doi: 10.1111/brv.12341 Cephalopod embryonic shells as a tool to reconstruct reproductive strategies in extinct taxa Vladimir Laptikhovsky1,∗, Svetlana Nikolaeva2,3,4 and Mikhail Rogov5 1Fisheries Division, Cefas, Lowestoft, NR33 0HT, U.K. 2Department of Earth Sciences Natural History Museum, London, SW7 5BD, U.K. 3Laboratory of Molluscs Borissiak Paleontological Institute, Russian Academy of Sciences, Moscow, 117997, Russia 4Laboratory of Stratigraphy of Oil and Gas Bearing Reservoirs Kazan Federal University, Kazan, 420000, Russia 5Department of Stratigraphy Geological Institute, Russian Academy of Sciences, Moscow, 119017, Russia ABSTRACT An exhaustive study of existing data on the relationship between egg size and maximum size of embryonic shells in 42 species of extant cephalopods demonstrated that these values are approximately equal regardless of taxonomy and shell morphology. Egg size is also approximately equal to mantle length of hatchlings in 45 cephalopod species with rudimentary shells. Paired data on the size of the initial chamber versus embryonic shell in 235 species of Ammonoidea, 46 Bactritida, 13 Nautilida, 22 Orthocerida, 8 Tarphycerida, 4 Oncocerida, 1 Belemnoidea, 4 Sepiida and 1 Spirulida demonstrated that, although there is a positive relationship between these parameters in some taxa, initial chamber size cannot be used to predict egg size in extinct cephalopods; the size of the embryonic shell may be more appropriate for this task. The evolution of reproductive strategies in cephalopods in the geological past was marked by an increasing significance of small-egged taxa, as is also seen in simultaneously evolving fish taxa. Key words: embryonic shell, initial chamber, hatchling, egg size, Cephalopoda, Ammonoidea, reproductive strategy, Nautilida, Coleoidea.
