Water boatman on stone at the bottom of a pool.
Water boatmen are aquatic bugs that have the hindlegs adapted as paddles for swimming.
They are flattened and swim the right side up whereas the similar looking backswimmers
(Notonectidae) are deep-bodied, have a keel-shaped back, and swim on their backs. Water
boatmen are mainly predaceous on small insect larvae but some species can also feed on
algae and on minute organisms such as rotifers and diatoms. They have wings and can leap
out of the water and take flight.
