Traskorchestia traskiana
(Stimpson, 1857)
Pacific beach hopper
Traskorchestia traskiana, the Pacific beach hopper, is a supralittoral amphipod inhabiting coastal beaches of the Pacific Northwest. Its activity patterns are directly influenced by tidal inundation cycles, with behavioral to periodic flooding in the zone above the high tide . The has been studied for its biology and behavioral responses to environmental conditions in nearshore .

Habitat
Supralittoral zone—the coastal area above the high tide on sandy or pebble beaches. Occupies the upper beach stratum subject to periodic wave wash and tidal flooding but not continuous submersion.
Distribution
Pacific Northwest, U.S.A.; coastal beaches of the eastern Pacific.
Behavior
Activity patterns and are modulated by tidal inundation. Exhibits behavioral responses to periodic tidal flooding, likely involving movement to avoid submersion or desiccation stress. Specific locomotor patterns and shelter-seeking behaviors have been observed in response to changing moisture conditions.
