The high levels of heterozygosity found in this study were in accordance with those found for echinoderms and other marine invertebrates using allozyme electrophoresis technique, for example: the sea anemone Anthopleura orientalis Averincev 1967 Hexp = 0.25 (Manchenko et al., 2000); the coral Sinularia flexibilis (Quoy & Gaimard, 1833) [H.sub.EXP] = 0.32 (Bastidas et al., 2001); the mussel Perna canaliculus (Gmelin, 1791) [H.sub.EXP] = 0.21 (Apte & Gardner, 2001); and the crustacean Litopennaeus setiferus (Linnaeus, 1767) [H.sub.EXP] = 0.59 (Ball & Chapman, 2003).
