The ecology, habits and functional morphology of Galeomma (Paralepida) takii (Kuroda) are described, and comparisons made with other free living and more specialized commensal galeommatids, other Leptonacea and other bivalve phylogenies.
Galeomma takii lives under stones at mid tide level and possesses both primitive and specialized characters which make it successful in such a restricted habitat. One of the most important specializations is numerous pallial tentacles that can autotomize and, it is thought, release a noxious substance to deter would be predators. Such a mechanism is advantageous for an animal living in a well defined ecological niche shared by other species, some of which may be predatory. Post settlement protection of the young also probably occurs.
