Common Atlantic sandhopper
Americorchestia longicornis, the common Atlantic sandhopper, is a beach-dwelling amphipod in the family Talitridae. It inhabits sandy coastal environments along the Atlantic seaboard, where it functions as a detritivore and scavenger. The species is distinguished from similar beach hoppers by its elongated antennae, as reflected in its specific epithet.
