Damselfish Revised

Those pesky Caribbean damselfish!  They have been confusing even the most experienced REEF surveyors for years! After consulting with the leading damselfish taxonomist experts, Paul Humann and Ned DeLoach revised the descriptions and updated pictures for four species - Cocoa Damselfish (Stegastes variabilis), Beaugregory (Stegastes leucostictus), Longfin Damselfish (Stegastes diencaeus), and Dusky Damselfish (Stegastes adustus).

The revised pages, meant to replace pages 124-129 in the 3rd edition of Reef Fish Identification, are available for download as PDFs below, courtesy of New World Publications. The text and pictures were reviewed by Dr. Ross Robertson with the Smithsonian's Tropical Research Institute in Panama, who is considered the world's authority on Western Tropical Atlantic damselfishes, and Dr. Mark Steele at University of California, Santa Barbara, another damselfish taxonomist.

Long-time REEF Advanced Assessment Team member, Neil Ericsson, has also compiled the key features into a handy matrix. This is available as a PDF here.
