A field guide to Kenyan mangroves
Ocypode ceratophthalmus (Pallas)
Zone: Sand flats in front of mangroves, but can also occur on sandy beaches.
Habitat: Sandy beaches and sand flats in front of mangroves (see also Burggren and McMahon, 1988).
Ecological notes: Much less common than O. ryderi. Just after the tide has gone out, these crabs start to maintan their burrows or dig new ones. They can be seen carrying sand to about 50-100 cm away from their burrow entrance, then throwing it as far as they can.
Attempts to occupy another crabs' burrow are frequently made and usually results in agressive fighting, which lasts only a few seconds (see below).
Distinguishing characteristics: long eyestalks on top of their eyes.
Geographical range: Indo-Pacific (Richmond, 1997)
