Summer is the time to dig for mole crabs (Emerita talpoida) and they become more abundant as season progresses.

They move back and forth with the tides by riding the swash at the shoreline, and feeding on organic debris with their feathery antennae.

Mole crabs are constantly on the move, burrowing and getting uncovered by the waves.

Males are only half the size of females (Which often carry an orange egg mass.).

Both sexes move into deeper water in the winter to avoid temperature extremes.

The crabs in these video clips are feeding on hatched brine shrimp.

They are fed upon by shorebirds like sanderlings, and many other creatures.
