The flashy Flamboyant Cuttlefish is among the most famous of the cephalopods (octopus, squid, and cuttlefish)—but it is widely misunderstood by its legions of fans.

An exquisitely well preserved 429-million-year-old eye from a marine creature that went extinct before dinosaurs even existed had vision comparable to modern-day bees and dragonflies, researchers said Thursday.

Men may have a surprising genetic advantage over women, according to new research carried out at the University of St Andrews.

Research of killer whales in the southern Atlantic ocean and Mediterranean have shown that their blubber contains high levels of pollutants called PCBs, whilst killer whales found along the Norwegian coast have been assumed to be healthy and at low risk from pollution. This is because when researchers took samples from nine Norwegian killer whales in 2002, they found lower levels of pollutants than other populations.

A team at the Marine Biological Laboratory (MBL) has achieved the first gene knockout in a cephalopod using the squid Doryteuthis pealeii, an exceptionally important research organism in biology for nearly a century. The milestone study, led by MBL Senior Scientist Joshua Rosenthal and MBL Whitman Scientist Karen Crawford, is reported in the July 30 issue of Current Biology.
