back to Home Cephalopods, Octopus back to Categories

Cephalopods are often hard to determinate, also because most Cephalopods posses the ability to change color. They do that by their Chromatophores, pigment-containing and light-reflecting cells, also found in amphibians, fish, reptiles, crustaceans. Sometimes the flash of a strobe makes them change color instantly. Next to that, a lot of Cephalopods, especially squid and cuttlefish, also use Bioluminescence produced by bacterial symbionts.

Cephalopods are the highest developed member of the mollusks; related to, for example, shells and nudibranch.

The name Cephalopods comes from the Greek and means head / foot. The main members are octopus, squid en cuttlefish, but also the seldom seen nautilus and argonauts are part of it. There are over 800 different species, all marine; there are no fresh water species.
