Scientific name: Notonecta sp.
(Hemiptera: Notonectidae)

Facts: Backswimmers are other predators that can also inflict a strong bite. They are backswimmers because they do indeed swim upside-down through the water. Their hind legs are very long and modified for use as oars. Because they swim upside-down, their body is shaped similar to a boat with the upper surface of the body keel shaped. Another adaptation for their back swimming behavior is that they are counter-shaded opposite of most creatures. Normal creatures have the upper body surface darker than the lower surface since this makes them less conspicuous. This coloration has been reversed in the backswimmer since it is advantageous while it is upside-down in the water.
