Transcriptome profiling of the posterior salivary glands of the cuttlefish Sepia officinalis from the Portuguese West coast

Frontiers in Marine Science
Cephalopods like octopuses and cuttlefishes are known to secrete a ‘toxic saliva’ to inject into their prey, especially crustaceans since the XIX century.

Sentience in cephalopod molluscs: an updated assessment

Biological Reviews, Volume 101, Issue 3, Page 1311-1333, June 2026.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Eocene belemnites from Hungary

Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract The Middle Eocene nummulitic limestone at Dudar, Transdanubian Hungary, has yielded several belemnite rostra during the last 60–70 years. The correct interpretation of these fossils was made possible by the fact that one of these specimens retained the remnants of the conotheca within the alveolus, while others preserved the conical, tapering ...

Microstructural and geochemical evidence offers a solution to the cephalopod cameral deposits riddle

Palaeontology, Volume 68, Issue 6, November/December 2025.
Abstract Orthoceratoid cephalopods are common in the Palaeozoic rock record but went extinct in the Late Triassic. Many orthoceratoids contain cameral deposits, which are enigmatic calcareous structures within their chambered shell that presumably balanced their straight conchs in a horizontal position. Since the mid‐19th century, palaeontologists have

The shell structure and chamber production cycle of the cephalopod Spirula (Coleoidea, Decapodiformes)

, 2022
Abstract The coleoid cephalopod Spirula spirula, the only present-day representative of the coleoid order Spirulida, secretes a coiled shell consisting of a series of chambers divided by septa and connected by a siphuncle. It is the shell closest to those of ectochleate cephalopods: nautiloids, ammonoids.

THE FIRST CENOZOIC OCTOPOD: A LOWER EOCENE RECORD FROM BOLCA, NORTHEASTERN ITALY

Rivista Italiana di Paleontologia e Stratigrafia
To date, soft-tissue remains of extinct incirrate octopods have been described exclusively from Upper Cretaceous deposits. Here, three specimens of an incirrate octopodid with well-preserved soft tissue imprints are described for the first time from ...
