Palaeobiology and evolutionary context of Angulithes mermeti, a streamlined early Late Cretaceous shallow-water nautiloid [PDF]
Cretaceous nautiloids are commonly characterized by inflated shells and prolonged stratigraphic ranges. In the Albian, the species of Angulithes appeared and compressed, short-lived forms with narrow venters emerged during the Cenomanian age.

Hettangian, Early Jurassic coleoids from West Somerset, SW England—filling a gap in the coleoid record of NW Europe [PDF]
The semi-articulated remains of two specimens of the putative diplobelid coleoid species of Clarkeiteuthis and a coleoid of uncertain affinity (possibly a phragmoteuthid) are described from a single bed in the Blue Lias Formation (early Hettangian ...

Behavioural aspects of the spotty bobtail squid Euprymna parva (Cephalopoda: Sepiolidae)
Bobtail squids (Sepiolidae, Cephalopoda) have recently been growing in popularity in scientific studies due to their symbiotic relationship with light producing bacteria and their corresponding light emitting organs. However, the overall knowledge on the

Relationship of Cephalopods Orders Based on Morphological Characters
Biodiversity is vital in our daily life. As a maritime country, Indonesian waters harbor many valuable animals such as Cephalopoda. Indonesian waters are rich in various species of cephalopods. Several previous studies on Indonesian cephalopods have been

Ontogeny, muscle scars, colour pattern and predation marks in a Silurian orthoceratid cephalopod [PDF]
Muscle scars, embryonic shell, colour pattern and intraspecific variation are known together in a very limited numberof straight shelled cephalopods, leading to uncertainty in the classification of the subclass Orthoceratoidea.
