Cephalopods, like the octopus, have specialized arms and suckers, but how these structures evolved from the simple bodies of their mollusk ancestors remains a mystery. Researchers from the University of Tokyo compared gene ...
Octopuses, squid and cuttlefish, collectively known as coleoid cephalopods, have evolved exceptionally large and elaborately structured nervous systems capable of complex behaviors such as problem-solving and rapid camouflage. ...
Plesiosaurs swam into river deltas to vomit up shells and other indigestible elements of their marine meals, suggests new research published by Cambridge University Press. The behavior resembles that of today's fur seals ...
Cephalopods are a group of soft-bodied marine mollusks that include cuttlefish, octopuses, squid and nautiluses. Many of these mollusks have muscular suckers on their arms that allow them to seize prey or grip other surfaces ...
This year's cuttlefish season has been unlike any other. Every winter, more than 100,000 giant Australian cuttlefish can usually be found mating along the rocky coastline of Point Lowly, northeast of Whyalla, South Australia. ...
Extant and ancient cephalopods—including octopuses, squids, extinct ammonites, cuttlefish and nautiluses—have all had to solve the problem of buoyancy, whether they have hard external shells or not.
The octopus is a biological oddity. It can use tools, open jars, and its complex nervous system supports as many neurons as a small primate. Now Harvard biologists have discovered a mysterious distinction in octopuses' core ...
An ongoing research project exploring the effects of rising levels of oceanic CO2 on squid neurology reveals that exposure to future levels of ocean acidification could shrink their brain volume by around 50%. This severe ...
Octopuses, squid and cuttlefish may have evolved large brains because of the challenges posed by their environments rather than the demands of social life, according to a new study published in iScience today.
How does a stripy tree snail hide from hungry birds? The Hypselostyla camelopardalis from the Philippines and Reinia variegata from Japan have both evolved a form of dynamic camouflage to survive. Their light-colored patterns ...
