	abstract = "The morphology of the burrows of the ghost crab <I>Ocypode ceratophthalmus</I> (Pallas, 1772) was studied at Ao Yon and Cape Panwa on the west coast of Thailand and, previously, at Sai Kaew on Thailand's east coast. Granulometric analysis showed that the sediment grain size and composition differed between sites. Thirty-three of 54 burrows (61%) from the west coast and 50 of 104 (48%) on the east coast were Y-shaped, the most common shape at all sites. Y-shaped burrows had one arm that opened on the surface and one which terminated just below the surface. The angles of descent of the two arms of the Y and the angle of the single descending shaft relative to the vertical, did not differ between: (1) juvenile and young adult crabs at Ao Yon, (2) juvenile crabs from Ao Yon and Cape Panwa, (3) juvenile crabs from both coasts. The precision with which this crab constructs Y-shaped burrows across sites and sediment types, indicates that burrow morphology is functionally important, perhaps for defence against predators.",
