The systematics and identification of larval cephalopods
from the northern North Pacific.
group of organisms (squids, cuttlefish, Octopuses) belongs to phylum Mollusca and has cosmopolitan distribution (Norman, 2000).
were identified by examination of beaks (Wolff, 1982, 1984; Clarke, 1986; Xavier and Cherel, 2009).
as Vectors of Cadmium Transfer to Cetaceans
In this study, we first used a computer screen to present different visual stimuli to cuttlefish, representing a potentially new experimental device for the behavioral study of cephalopods
, allowing results to be compared between phylogenetically different animal groups.

All year, I have been seeing reports of greater and greater numbers of all cephalopods
in UK waters, especially octopuses.
"We were drawn by how successful cephalopods
are at changing their skin texture, so we studied and drew inspiration from the muscles that allow cephalopods
to control their texture, and implemented these ideas into a method for controlling the shape of soft, stretchable materials."
This process, called RNA editing, is an extremely rare exception in most animal groups, but among coeloid cephalopods
, this seems to be widespread.
This exciting and extremely rare intertidal encounter has prompted a formal report on the sighting and also an overview of the biology of this species and of cephalopods
