We just learned about the Bigfin Reef Squid.
Another type of cephalopod is the Argonaut Octopus.
These octopuses are sometimes called a "paper nautilus" because the female argonaut will make a hard shell to lay their eggs in, and they will have part of their body in this shell, curled up and looking like a nautilus.
They lay their eggs in the shell, and then sometimes even after the eggs hatch they keep the shell and live in it.
The male argonaut does not have a shell. Both the males and females have eight arms just like all other octopuses.
