Miocene sepiids (Cephalopoda, Coleoidea) from Australia [PDF]
Fossil Record, 2017 Two sepiid genera, Notosepia Chapman, 1915, andSepia Linnaeus, 1758, are described from the Neogene deposits ofAustralia. A new and unique record of the middle Miocene Sepia sp.is reported from southern Australia.

Development of a DNA Metabarcoding Method for the Identification of Crustaceans (Malacostraca) and Cephalopods (Coleoidea) in Processed Foods [PDF]
FoodsSeafood is a valuable commodity with increasing demand, traded for billions of USD each year. The volatility in supply chains and fluctuating prices contribute to the susceptibility of the seafood market to food fraud.

‘Arm brains’ (axial nerves) of Jurassic coleoids and the evolution of coleoid neuroanatomy [PDF]
Swiss Journal of Palaeontology, 2023 Although patchy, the fossil record of coleoids bears a wealth of information on their soft part anatomy. Here, we describe remains of the axial nerve cord from both decabrachian (Acanthoteuthis, Belemnotheutis, Chondroteuthis) and octobrachian ...

Anatomy and evolution of the first Coleoidea in the Carboniferous [PDF]
Communications Biology, 2019 AbstractColeoidea (squids and octopuses) comprise all crown group cephalopods except the Nautilida. Coleoids are characterized by internal shell (endocochleate), ink sac and arm hooks, while nautilids lack an ink sac, arm hooks, suckers, and have an external conch (ectocochleate).

Pterosaurs ate soft-bodied cephalopods (Coleoidea) [PDF]
Scientific Reports, 2020 AbstractDirect evidence of successful or failed predation is rare in the fossil record but essential for reconstructing extinct food webs. Here, we report the first evidence of a failed predation attempt by a pterosaur on a soft-bodied coleoid cephalopod.

Transcriptomic analysis of oxidative stress mechanisms induced by acute nanoplastic exposure in Sepia esculenta larvae [PDF]
Frontiers in Physiology, 2023 Nanoplastics (NPs), as a new type of pollutant with a size small than 1 μm, are ubiquitous and harmful to organisms. There has been an increasing amount of research concerning the effects of NPs on organisms over recent years, especially on aquatic ...

Distraction sinking and fossilized coleoid predatory behaviour from the German Early Jurassic [PDF]
Swiss Journal of Palaeontology, 2021 Exceptional fossil preservation is required to conserve soft-bodied fossils and even more so to conserve their behaviour. Here, we describe a fossil of a co-occurrence of representatives of two different octobrachian coleoid species. The fossils are from

An Eocene orthocone from Antarctica shows convergent evolution of internally shelled cephalopods. [PDF]
PLoS ONE, 2017 BackgroundThe Subclass Coleoidea (Class Cephalopoda) accommodates the diverse present-day internally shelled cephalopod mollusks (Spirula, Sepia and octopuses, squids, Vampyroteuthis) and also extinct internally shelled cephalopods.

Analysis of catch rates of LED lamps using on the falling-net fishing vessels in South China Sea. [PDF]
PLoS ONEFalling nets are a type of fishing gear that appeared and developed rapidly in the northern of South China Sea in the early 1990s. We have developed Light-emitting diode (LED) fishing lamps to replace metal halide (MH) lamps that reduce fuel consumption ...

Genus-level phylogeny of cephalopods using molecular markers: current status and problematic areas [PDF]
PeerJ, 2018 Comprising more than 800 extant species, the class Cephalopoda (octopuses, squid, cuttlefish, and nautiluses) is a fascinating group of marine conchiferan mollusks.
