    Abstract

    This report provides a synopsis of fil.'1d studil'S of RiI'll/liS man1l0ralllS from two population surveys of mangro\'C islands adjacent to the Belize barrier fl'Cf and observations made over fifteen years at several sites in South Florida. Florida populations consist ne.uly exclusively of hermaphrodites (> 99%), while the Belize populations containl'<i a significant proportion (10·25%) of males. Our combined observations demonstrate that this species is not "rare" as previously thought, but elusive and highly adapted to microhabitats within mangrove forests. Standard ichthyo· logical collecting techniques are indfl'Ctive in this habitat and have previously failed to reveal the strength of the association of R. mllrm"mllls with the mangral ecosystem.
