Triassic coleoid beaks and other structures from the Calcareous Alps revisited [PDF]
Acta Palaeontologica Polonica, 2022 We performed comprehensive study of seven Carnian, Late Triassic specimens of a coleoid cephalopod Phragmoteuthis bisinuata, on which Suess based his hypothesis on “beaks of P. bisinuata”. Using SEM/EDS, we found that “beaks of P.

BMC Biology, 2021 In zoology, species descriptions conventionally rely on invasive morphological techniques, frequently leading to damage of the specimens and thus only a partial understanding of their structural complexity.

Impact of Lidocaine on Pain-Related Grooming in Cuttlefish
Biology, 2022 Nociception is the neural process of encoding noxious stimuli and is typically accompanied by a reflex withdrawal response away from the potentially injurious stimulus.

Non-destructive analysis of pathological belemnite rostra by micro-CT techniques [PDF]
Acta Palaeontologica Polonica, 2020 Previously, palaeopathological features of fossil hardparts were often difficult to interpret because it was impossible to decipher their internal structure without destroying the specimens. We applied high-resolution computedtomo graphy (CT) to document

Pseudogzheloceras—a new genus of Carboniferous nautilids (Cephalopoda) from Europe and North Africa
Geo&Bio, 2021 Analysis of morphology, stratigraphic and geographic distribution of the group of nautilid species, mainly from the Westphalian of Western Europe, and the Bashkirian and Moscovian of the Donets Basin (Eastern Ukraine) made it possible to establish a new ...

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 ...

Çanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries, 2021 This study aimed to determine the spatial and temporal variation of species diversity and CPUE in trawl fisheries in the Central Aegean Sea (Sığacık Bay). The study also aimed to evaluate changes in some biometric parameters (mean and frequency of length)

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 ...

Marine Biology, 2020 The Cephalopoda are not typically considered characteristic of the benthic fauna at hadal depths (depths exceeding 6000 m), yet occasional open-net trawl samples have implied that they might be present to ~ 8000 m deep.
