like most nudibranchs this species has no official common name. they can be found in tropical Indo-Western Pacific oceans. they grow up to 50mm in length and their body is black but their external organs are edged in a almost neon green like color. they are poisonous and get their poison from the stinging cells of fallen Cnidarians.
