There are over 700 living species that belong to the class Cephalopoda (a name derived from Greek meaning “head-footed”). The general build of these animals includes a head, which contains all of the cephalopod’s organs, and the foot, which can consist of many appendages. At its center, the cephalopod has a sharp beak made of keratin (the same material that makes up our hair/fingernails)!
Cephalopods, including the well-known octopus, cuttlefish, squid and nautilus, inhabit all of the world’s oceans and can be traced back almost 500 million years.
Cephalopods are highly-intelligent creatures. In fact, they have the biggest brains of any invertebrate. Their cunning nature and ability to disguise themselves perfectly against almost any background make them worthy predators!
