Caribbean Marine Occurrence in Mangroves of a Typically Fresh-water Synbranchiform Fish


The capture of the swamp eel Ophisternon aenigmaticum in the hypersaline waters of a mangrove island 15 km off the coast of Belize, Central America, is the first marine record for any of the New World species of Synbranchiformes, with dispersal from the mainland through sea water sometime in the past 7,000 years the likely explanation for its island occurrence.
