Predatory behaviour and taphonomy of a Jurassic belemnoid coleoid (Diplobelida, Cephalopoda)

open access: yesScientific Reports, 2019
We describe four complete specimens of the early squid-like cephalopod Clarkeiteuthis conocauda from the Toarcian Posidonienschiefer (Jurassic) each preserved with the bony fish Leptolepis bronni in its arms. Based on the arrangement of prey and predator,

Description of a new sepioline species, Sepiola bursadhaesa n. sp. (Cephalopoda: Sepiolidae), from the Catalan Sea, with remarks and identification key for the Sepiola atlantica group

open access: yesScientia Marina, 2013
Diversity among members of the genus Sepiola (Cephalopoda: Sepiolidae) in the NE Atlantic-Mediterranean area is fairly high; 10 species have been recorded. In this paper, a new species, Sepiola bursadhaesa n. sp., is described based on ten specimens from

The first global deep-sea stable isotope assessment reveals the unique trophic ecology of Vampire Squid Vampyroteuthis infernalis (Cephalopoda)

open access: yesScientific Reports, 2019
Vampyroteuthis infernalis Chun, 1903, is a widely distributed deepwater cephalopod with unique morphology and phylogenetic position. We assessed its habitat and trophic ecology on a global scale via stable isotope analyses of a unique collection of beaks

Reproductive biology and ecology of the boreoatlantic armhook squid Gonatus fabricii (Cephalopoda: Gonatidae)

open access: yesJournal of molluscan studies, 2019
The squid Gonatus fabricii (Lichtenstein, 1818) is the most abundant pelagic cephalopod in the Arctic and the only squid to spend all of its life cycle in this region.

In Vivo Recording of Neural and Behavioral Correlates of Anesthesia Induction, Reversal, and Euthanasia in Cephalopod Molluscs

open access: yesFrontiers in Physiology, 2018
Cephalopod molluscs are among the most behaviorally and neurologically complex invertebrates. As they are now included in research animal welfare regulations in many countries, humane and effective anesthesia is required during invasive procedures ...

Techniques for Estimating the Age and Growth of Molluscs: Cephalopoda

open access: yesJournal of Shellfish Research, 2018
Global abundances and commercial fisheries of cephalopods have increased over recent decades, creating a need for effective fishery management. This management is often focused on the ability to ascertain the age structure of key populations.

Fecundity of the common cuttlefish, Sepia officinalis L. (Cephalopoda, Sepiida): a new look at the old problem

open access: yesScientia Marina, 2003
The potential fecundity (PF) of advanced maturing and mature pre-spawning cuttlefish S. officinalis in the Aegean Sea varies from 3,700 to 8,000 (mean 5,871) oocytes, whereas the number of large yolk oocytes increases with mantle length from 130 to 839 ...
