A field guide to Kenyan mangroves
Zone: Tidal flats in front of mangroves.

Ecological notes: Richmond (1997) lists five species of Macrophthalmus in East Africa: M. depressus (all images on this page are of M. depressus), M. grandidieri, M. boscii, M. latreillei and M. milloti with the first two being more associated with mangroves (Richmond, 1997; pers obs).
Notice the burrow just to the right of the crab
Distinguishing characteristics: Carapace broader than long. M. depressus has three lateral teeth on carapace, the last being very small; inner palm covered with thick hair (Richmond, 1997). M. grandidieri can most easily be recognized by its strangely shaped claws.
