Cenocorixa bifida
water boatman
Cenocorixa bifida is a species of water boatman (family Corixidae) first described by Hungerford in 1926. It is found in North America and possesses the characteristic rowing hind legs typical of water boatmen, which it uses for propulsion through synchronous swimming strokes. The species has been studied for its swimming hydrodynamics and Malpighian tubule ultrastructure, revealing specialized adaptations for aquatic life.
