This animal is called Gibberulina tantilla in a some Japanese Shell and Nudhubranchs ID book. If it's correct, is it a snail or an opisthobranch? Its head looks quite like the head shape of Colpodaspis to me.

This animal is a snail of the family Marginellidae. Its head does have the look of Colpodaspis and unlike most snails, the eyes do not seem to be associated with tentacles. But its shell and anatomy are definitely not opisthobranch.
