ain't no sea cucumber

one thing I know I'm not, is a sea cucumber.

A small octupus, maybe, because "Octopuses have the most complex brain of the invertebrates" or even a squid because "their strong parrot like beak allows them to tear flesh so they can actually eat creatures much bigger than themselves."

But for sure one of the two as I'm sure I squirt a dark cloud when attempting to escape or confuse a predator and because the "first avenue of defence is camoflage, which they achieve by altering their appearance."

Octopi change colors depending upon their mood.
