Smooth-eye ghost crab
Ocypode cordimanus
Family Ocypodidae
updated Sep 11
Where seen? This crab is seldom seen, usually on the higher shore. It was previously also called Ocypode cordimana.

Features: Body width about 5cm. Box-like body with large grooves for the eyes to fold away. Pale greyish blue without dark markings on the back of the body. Pincers large and downward pointing. Legs very long with pointed tips. It lacks ridges on the inner palm of the pincers.

May be mistaken for the Long-eyed ghost crab (Ocypode ceratophthalmus): the Smooth-eyed ghost crab lacks 'horns' and seems a little slower and less skittish. It lacks ridges on the inner palm. But juvenile Long-eyed ghost crabs also lack 'horns' and tend to remain immobile when spotted.

Sentosa, Sep 11
Status and threats: The Smooth-eyed ghost crab is listed as 'Vulnerable' in the Red List of threatened animals of Singapore.

Back without dark marks.

Eyes without 'horns'.

Lacks ridges on inner palm.
