    Abstract

    Qualitative and quantitative collecting was undertaken in 1987 to determine the species composition, abundance, and distribution of hydroids in a mangrove system at Twin Cays, Belize. Of 49 species identified, the 5 most frequent were Ventromma halecioides, Nemalecium sp., Clytia hemisphaerica, Dynamena crisioides and Halopteris diaphana. Line-transect census data and qualitative observations showed that the hydroid fauna was sparse in sheltered, still-water areas of the mangal, but relatively abundant and diverse in areas exposed to waves and/or tidal currents. Species composition and relative abundance varied with depth at stations in exposed locations and in tidal creeks and channels. Although Turritopsoides brehmeri is known only from Twin Cays at present, it seems improbable that any of the species is restricted to mangrove ecosystems.
