| This is a very
large family (possibly >2000 spp.) of mostly marine and brackish species.
Mostly of small size, they tend to be cryptic bottom dwelling carnivores
feeding on small benthic invertebrates. Very common in fresh waters on
oceanic islands (Nelson
1994). Thus, it is not surprising that all four hypogean
species described thus far are from islands: two from Japan, one from the
Philippines and one from Madagascar. The two
species of Luciogobius seem to be valid based on the differences in
their meristic, non-troglomorphic differences and allopatry; both of them
most probably descended from Luciogobius guttatus. The third
species also seems to be valid: the monotypic genus Caecogobius
does not appear to be related to any other extant species. More
information is needed regarding the fourth, Glossogobius ankaranensis,
given the fact that it has been found syntopically with the congeneric
Glossogobius callidus. |
