Octopus
(Octopus bimaculoides)

Normally
nocturnal, this highly developed mollusk can occasionally
be seen during daylight hours. Growing up to 3 feet, it has
an uncanny ability to change color and even texture at a moments
notice. The octopus feeds on small fish and invertebrates
such as crabs, shrimp, limpets, mussels, cowries and blennies.
The octopus will bite its prey with its "beak", injecting
a saliva that is laced with a toxin, anesthetizing the prey.
This mollusk seems highly intelligent and has been able to
open a twist top jar to get at food in laboratory experiments.
There is an almost identical species, Octopus bimaculatus,
that lives in shallower water. The two species' ranges overlap
and only an expert can tell them apart. The major predator
of the octopus is the California Moray.
