Conellae, enigmatic structures on cephalopod shells—shapes, distribution, and formation [PDF]
Acta Palaeontologica Polonica, 2019 Conellae, enigmatic cone-shaped structures which can be found on the surface of internal moulds of cephalopod shells (predominantly of ammonoids), are regarded herein as the product of remote (biologically induced) biomineralization formed in closed-off ...

Mapping molluscan endocrinology: a systematic and critical appraisal. [PDF]
Biol Rev Camb Philos SocABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Fatty Acids and Stomach Contents Reveal Dietary Overlaps of Two Prospering Squid Species in the North Sea. [PDF]
Ecol EvolDistribution ranges of cephalopods are expanding worldwide and their abundances are increasing due to ocean warming. Recently, the broadtail shortfin squid Illex coindetii (Ommastrephidae) expanded into the North Sea where it established a successful spawning stock beside the resident veined squid Loligo forbesii (Loliginidae).
