Topographical distribution of visual cell nuclei in the retina in relation to the habitat of five species of Decapodiformes (Cephalopoda) [PDF]
Journal of Molluscan Studies, 2010 Studies of retinal histology of fish have established that the position of an area of high cell density reflects both the habitat and feeding behaviour. Here, we discuss potential relationships between biology, specifically behaviour and ecology, and visual axes (estimated from density of visual cell nuclei) in five species of Decapodiformes.

AbstractIn molecular phylogenetics, mode of analysis is typically the primary reason cited for obtaining different topologies. However, sequence alignment is as important in determining topology as analytical method or optimality criterion, particularly for length‐variable sequences.

Electron microscopy revealed that glial cells in the posterior sub-esophageal mass of the brain in Sepia officinalis had a well-developed rough endoplasmic reticulum formed by long coverslips with rectilinear or curvilinear arrangements. The coverslips appeared dilated and have a large amount of adhered polysomes.

A new genus and three new species of decapodiform cephalopods (Mollusca: Cephalopoda)
Reviews in Fish Biology and Fisheries, 2007We describe here two new species of oegopsid squids. The first is an Asperoteuthis (Chiroteuthidae), and it is based on 18 specimens. This new species has sucker dentition and a funnel–mantle locking apparatus that are unique within the genus. The second new species is a Promachoteuthis (Promachoteuthidae), and is based on a unique specimen.

Squids, cuttlefish and bobtail squids comprise the molluscan superorder Decapodiformes (Mollusca: Cephalopoda). Although these animals exemplify the morphological and ecological diversity seen in Cephalopoda, no previous study has focused resolving decapodiform relationships, particularly within Oegopsida, a large order comprised of pelagic squid.

We determined the complete mitochondrial (mt) genomes of the deep-sea squid (Bathyteuthis abyssicola; supperfamily Bathyteuthoidea), the bob-tail squid (Semirossia patagonica; order Sepiolida) and four giant cuttlefish (Sepia apama, S. latimanus, S. lycidas and S. pharaonis; order Sepiida).

Brooding and sperm storage by the deep-sea squid Bathyteuthis berryi (Cephalopoda: Decapodiformes)
Journal of the Marine Biological Association of the United Kingdom, 2012Squids of the family Bathyteuthidae have generally been infrequently encountered in their deep-sea habitat. Remotely operated vehicles were used to observe seven individuals in situ in the Monterey Submarine Canyon, CA, USA. One of these was a female Bathyteuthis berryi holding a sheet with approximately 360 embedded embryos. Examination of this female

We report the first complete mitochondrial genome of the pygmy squid, Idiosepius, (Idiosepiidae). The mtDNA genome is 16,183 bp long with an AT content of 75.4%. All conserved metazoan mitochondrial genes are identified with the addition of a 1018 bp non-coding region.

Neocoleoid cephalopods are poorly represented in the fossil record and fossils which can be confidently aligned with extant species are very scarce. The rare Solnhofen genus Palaeololigo is an exception to this, showing marked resemblance to Recent squids. Naef misinterpreted the structure of the fossilized gladius of Palaeololigo and the present study
