Ocypode rotundata, also known as the rounded ghost crab, is a large-sized species of Ocypode found in the southern coast of theÃÂ Arabian PeninsulaÃÂ to northern India (from OmanÃÂ toÃÂ Bombay), including theÃÂ Persian Gulf. They are very similar toÃÂ O. saratanÃÂ but can be distinguished by having 10 to 15 irregularly spaced elongated tubercles with striae on their stridulating ridges and a thumb-like palp on their gonopods. Their eyestalks possess styles.
