or beach flea
Hopping terrestrial crustacean (family Talitridae).
The European sand flea ( Talitrus saltator ) is about 0.6 in. (1.5 cm) long. The long-horned sand flea ( T. longicornis ), found on the North American Atlantic coast, has antennae the same length as the waxy white body, up to 1 in. (2.5 cm) long. During the day, sand fleas lie buried near the high-tide mark; at night, they forage for organic debris. The common sand flea ( Orchestia agilis , or platensis ) lives along Atlantic coasts of Europe and the Americas.
