New insight into the hunting patterns of ancient cephalopods

The Jurassic cephalopod Vampyronassa rhodanica, thought to be the oldest known ancestor of the modern-day vampire squid (Vampyroteuthis infernalis), was likely an active hunter—a mode of life that is in contrast with its ...

Squid recorded color-matching a substrate for the first time

While octopus and cuttlefish are famous for their use of camouflage to match the color of the substrate, squid have never been reported displaying this ability. Now, in a study published in Scientific Reports, scientists ...

Researchers investigate squid found far from home

As the name implies, California market squid are often sold in stores and typically found between Baja California and Monterey Bay. So, the squid's periodic appearance in the Gulf of Alaska—about 1,200 kilometers (745 miles) ...

Deepest-dwelling squid observed at depth of 6,200 meters

A pair of researchers, one with the University of Western Australia, the other NOAA National Systematics Laboratory, has recorded on video a young bigfin squid swimming just above the seafloor at an approximate depth of 6,200 ...

How animals repurpose genes to develop both limbs, eyes

The last common ancestor of cephalopods and vertebrates existed more than 500 million years ago. In fact, a squid is more closely related to a clam than it is a to a person. Even so, the two lineages independently evolved ...

Squid

†Plesioteuthididae (incertae sedis) Myopsina Oegopsina

Squid are marine cephalopods of the order Teuthida, which comprises around 300 species. Like all other cephalopods, squid have a distinct head, bilateral symmetry, a mantle, and arms. Squid, like cuttlefish, have eight arms and two tentacles arranged in pairs. (The only known exception is the bigfin squid group, which have ten very long, thin arms of equal length.)
