Sand Hopper (Talitrus saltator)

Sand Hopper, scientifically Talitrus saltator, is a common amphipod crustacean of sandy coasts around Europe. Its typical hopping movement, which gives it its common name, is produced by suddenly extending its abdomen from under its body while standing on its legs, letting it leap several inches into the air with no control over direction, and it has been the subject of extensive research into the environmental cues it uses to control its behavior.
