Odontodactylus scyllarus, the peacock mantis shrimp, is beautifully colored with the greens, blues and pinks of a peacock. It lives in the warm waters of the Indo-Pacific and builds U-shaped burrows in gravel substrates. Odontodactylus scyllarus belongs to the Order Stomatopoda, which is a large and diverse clade of marine crustaceans. All stomatopods have specialized appendages for spearing or hammering prey.

Odontodactylus scyllarus

Peacock mantis shrimps use the rounded heel of their raptorial appendages to hammer prey, generating extraordinary forces. Recent studies have shown that they can produce forces that are thousands of times their body weight. In addition, their appendage moves through the water so quickly that the water vaporizes in a process called cavitation. The implosive collapse of these cavitation bubbles generates substantial forces that follow each hammer-strike.

About the Species

This specimen, a female, was made available to the University of Texas High-Resolution X-ray CT Facility for scanning by Dr. Adam Summers of the Department of Ecology and Evolutionary Biology, University of California at Irvine. Funding for image processing was provided by a National Science Foundation Digital Libraries Initiative grant to Dr. Timothy Rowe.
