Clea nigricans[1] is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Buccinidae, the true whelks, most of which are marine.[2][3]
Distribution
This Southeast Asian species occurs in the Malaysian member states Sabah and Sarawak on Borneo.[4]
Feeding habits
Like all snails in the clade Neogastropoda, this species is carnivorous. It feeds on different types of worms and gastropods, often eating other, larger snails after burying themselves and ambushing their prey.[3]
Reproduction
Clea nigricans consists of defined male and female genders, and is not capable of gender change. It is unknown as to how to sex these animals. Both males and females seem to be the same size and shape. When a male and female mate, they lock together for 8-12 hours.
