Crustaceans - Living at the sea's edge
Subtidal | Tidal | Semi-terrestrial

The ghost crab (Ocypode) will go into the surf to wet its gills, but can drown if held underwater. Look for their burrows in the dunes. Ocypode means "swift-footed" and they are difficult to see or catch on the beach. Return them to their burrows if you catch one and don't try digging them out since the holes go down almost 4-feet.

(Left) Seaweed and beach hoppers are common just above the tideline. They are scavengers and eat whatever washes ashore with the waves.

 


The grass shrimp (Palaemonetes) is commonly found hiding along vertical objects like bulkheads and marsh grasses.

 Sometimes after storms, hermit crabs (Pagurus) are found
washed up on the beaches. These are not the
semi-terrestrial species from the tropics that
are sold in pet stores, and should be returned to
the water.
