We just learned about the Cephalopod Skin.
Another part of a squid's body is the Statocyst.
This is a sac inside the squid's head that has small hairs and a hard ball inside it.
When the squid swims around, the ball rolls around inside and moves the hairs, and the squid can tell which way it is swimming.
It also can use this statocyst to hear low sounds, when the sound is loud and the hairs are vibrating the sac.
