Animal Update: Chambered Nautiluses in Sensing

Three chambered nautiluses have been added to our Sensing exhibit! 

Published July 24, 2015

Chambered nautilus

A nautilus, along with the cuttlefish, squid, and octopus, are all cephalopods, meaning "head-foot," so named because the feet (tentacles) are attached to the head.

The nautilus is the only cephalopod that has a fully developed shell for protection. Unlike a squid, cuttlefish or an octopus, the nautilus has poor vision and its primitive eyes have no lenses. The nautilus has more than 90 suckerless tentacles.

Grooves and ridges on the tentacles are used to grip prey and deliver food to a crushing, parrot-like beak.

Stay tuned for more behind-the-scenes updates!
