We just learned about the Joubin's Squid.
Another cephalopod is the Southern Sand Octopus, also called octopus kaurna.
This octopus lives around Australia, and grows up to about 20 inches long, with very thin arms.
This octopus can not change colors like a lot of others can, so it stays hidden by burying itself in the sand.
It goes down by the bottom of the sea, and spits out a big jet of water down into the sand, then use its arms to quickly dive down into the hole it made.
