A field guide to Alaskan corals

Abstract

This guide presents updated keys to genera and species of corals known from Alaskan waters. The keys rely on macroscopic characters as much as possible. Where microscopic examination is required to identify species, the identification is carried only to genus or group of genera. Keys to the Octocorals (soft corals, gorgonian corals, sea pens and sea whips), Scleracatinia (cup corals), and Antipatharia (black corals) are carried only to genera. The keys to Hydrocorals are to species. Photographs of representatives of each genus are used to assist in identification. Where possible, photographs of fresh specimens are included. A brief glossary defines specialized terms used to describe corals. We present a list of the 105 coral species reported from Alaska. Some of the reported species may be synonyms or misidentifications.
