Cephalopods (meaning "head foot") are
mollusks with tentacles and a large head.
These soft-bodied invertebrates include animals like
squid, octopuses and cuttlefish.
They are fast-moving carnivores that catch prey with their tentacles and
poison it with a bite from beak-like jaws.
They move by squirting water through a siphon, a type of jet propulsion.
Many also squirt ink to help escape predators.
The octopus is an example of cephalopod
