Description

The species in this genus differ from the other genera in this family by possessing an elongate foregut and fused oral tentacles.[2]

Distribution

These nudibranchs can be found in the tropical Indo-Pacific region, the eastern Pacific region, in the Red Sea, in the Caribbean Sea and a few in the Northwest Atlantic Ocean. About half of the described species can be found in deep waters. Among these deep-water sea slugs, there is a group of white species, lacking all contrasting colors.[3][4]
