This mollusk is a master of disguise.

Cuttlefish

Posted October 23, 2013

The dwarf cuttlefish (Sepia bandensis) doesn’t need to worry about finding a new Halloween costume each year; it can change its skin color instead! When the cuttlefish encounters a new environment, pigment sacs called chromatophores expand and contract, creating different colors. The chromatophores can also mimic textures, movement and light patterns, making the cuttlefish a master of disguise that can fool both predators and prey.

Cuttlefish are mollusks with an internal shell. They are closely related to octopi, squid and other cephalopods.

See the cuttlefish’s camouflage for yourself and visit hundreds of colorful fish every day at the Aquarium. And this weekend, join us at Zoo Boo 25 to show off your own costume.
