amphipods
Small aquatic crustaceans
Amphipods are small crustaceans with laterally compressed bodies, found in marine, freshwater, and moist terrestrial environments.
Most are scavengers or detritivores.
The group includes sand fleas and whale lice.
The sample contained dozens of amphipods.
They serve as important food sources for fish and other aquatic animals.
