Canidia bizonata Deshayes, 1876 Clea broti[2] is a Southeast Asian species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Buccinidae, the true whelks, most of which are marine.

[3] Clea broti occurs in the Mekong River in the Khong District, Champasak Province in southern Laos and in Kas Lognieu, Sambor, and Sandan in Cambodia.

[4] 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.

When a male and female mate, they lock together for 8–12 hours.
