The Broadclub Cuttlefish can be frequently found on Indo-Pacific reefs.  They are considered among the most intelligent invertebrates, communicating via rapidly changing color patterns on their bodies.  They can also quickly change the texture of their bodies as well.  They have the best eyesight of all invertebrates, and many scientists believe their eyesight rivals that of humans.
