This is a pleurobranch with a very broad foot and relatively flattened body, which makes it ideal for crawling over soft sand and for burrowing. It has a wide oral veil (that's shaped like a moon, hence its name) with sensory papillae underneath, which it uses for locating food. This species burrows under sand but keeps its rhinophores and pallial siphon unsubmerged.
Spotted this (and another smaller individual) at around 12m depth during a night dive. It measured about 10cm long (the smaller one about 8cm). Both slugs were very active on the sand.
