Part of the long-arm octopus complex.
Under rock initially, then on surfgrass. Found near sunset.
The octopus was hiding under a rock and popped out. It was as big as the palm of my hand.
This was a small octopus found near the tide pools.
Two octopi seen tonight. The first one I saved from a gull that was carrying it off. It was kind enough to let me photograph it, before slinking away. The second one was not quite as photogenic.
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural κεφαλόποδα (kephalópoda); "head-feet"). These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishermen sometimes call them inkfish, referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology.
