D.R. Calder, ROMIZ B3978. Remarks . Although often reported from hard bottoms, Aglaophenia latecarinata Allman, 1877 is also a conspicuous epibiont of the pelagic gulfweed species Sargassum fluitans (Calder 1995). As such it is ubiquitous in the Caribbean Sea (e.g., Leloup 1935; Van Gemerden-Hoogeveen 1965), Gulf of Mexico (e.g., Fraser 1944; Defenbaugh & Hopkins 1973), Florida Current (e.g., Nutting 1895, as Aglaophenia minuta Bogle 1975), Gulf Stream (e.g., Burkenroad, in Parr 1939, as A. minuta Rackley 1974), and Sargasso Sea (e.g., Broch 1913; Leloup 1937). Colonies on gulfweed are stunted, as with certain other Sargassum associates (Adams 1960), and they typically reach only about a centimeter in height on that substrate. While the species tends to be a dominant hydroid on S. fluitans , it is much less frequent on S. natans , the other holopelagic species of gulfweed in the North Atlantic (Calder 1995). Hydroids of A. latecarinata are known to occur as well on flotsam such as plastics (Calder 1997). The troubled nomenclature and extensive synonymy of this species have been reviewed elsewhere (Bogle 1975; Calder 1997; Ansín Agís et al . 2001). The last group of authors also provided detailed distribution records. Reported distribution. Atlantic coast of Florida. Hollywood, near Miami (Leloup 1935; Fraser 1944). Western Atlantic.
