Crescent Octopus

Last weekend I found this unusual little octopus in a cavern at Honaunau. I was photographing a Sculptured Slipper Lobster when I noticed the "background" moving. It turned out to be a seldom-seen Crescent Octopus (Octopus hawaiiensis) and a first sighting for me.

This is a small octopus with a body smaller than a ping-pong ball and the tips of the tentacles all appear to be curled. Its movements appeared somewhat jerky compared to those of the common Day Octopus (Octopus cyanea).

It was a nice discovery in a little nook in the reef that was packed with invertebrates. In addition to this octo and the slipper lobster, there was also a large Flameback Shrimp just outside these frames.
