Cybister lateralimarginalis 10-05-2008
Cybister lateralimarginalis

This male specimen just made a rowing stroke with its oar-like hind legs. Notice the sucker discs on the front legs. It keeps these legs retracted under the head while swimming.

This beetle swims at ease, with a slow rowing movement. When it moves close to the bottom it surprisingly makes more use of the smaller middle legs, in stead of using the much more powerful hind legs.
