Cephalopod - Cirrus


We just learned about the Cephalopod Eyes.

Another part of the Cephalopod is the Cirrus.

A cirrus is a type of harder tentacle that doesn't bend as well, and doesn't have any suckers or hooks.
More than one cirrus is called cirri.

The nautilus has cirri that it uses to grab it's prey.
Each cirrus has ridges on it, so they use that to try and hold on really strong.
They hold on so strong with their cirri, that if the prey does get away they have probably ripped the cirri right off!
