Horned ghost crab

Ocypode ceratophthalma

The horned ghost crab is the one that digs all the holes that can be found on the beaches of Onetahi.

A pale crab races across the sand, then disappears into a hole. Its raised eyes and quick retreat make it one of the easiest beach residents to notice—and the hardest to approach.

About this species

The horned ghost crab digs many of the burrows seen on Onetahi. It is a true crab, unlike hermit crabs and coconut crabs. Its angular, almost square body often carries an H-shaped marking, while sandy colours hide it when it stops moving. Projections above the eyes give the species its common name.

It can run at about 2.1 metres per second. Deep burrows provide refuge from the heat and drying air; the crab usually emerges at night. Although it moves easily on land, it still needs moisture for respiration.

It gets its name from the horn like eyes that protrude up from its body and its sandy color that makes it blend into the background when it stands still.
