Abstract
The pygmy seahorse, Hippocampus bargibanti Whitley, 1970 (Osterichthys: Syngnathidae), is an obligate symbiont of gorgonians. The seahorses mimic their host’s colors and shapes and are highly dependent on them. Their hosts are limited to five species of the genus Muricella (Octocorallia: Anthogorgiidae). Symbiosis with other Octocorallia genera has not been reported. However, the host gorgonians are difficult to identify due to limited availability of key taxonomic characteristics. In this study, we describe a pygmy seahorse living symbiotically with a gorgonian in the Kochi Prefecture, Shikoku, Japan. The gorgonian was dissected, morphologically characterized, and identified as a new host species from the genus Anthogorgia (Anthogorgiidae) rather than Muricella, based on differences in sclerite morphology. This is the first study to identify this genus as a host of H. bargibanti. Accurate understanding of host selectivity would be useful in the study of H. bargibanti conservation and ecology.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
