Pachygrapsus minutus is a species of small shore crabs in the family Grapsidae.[1]
Pachygrapsus minutus has a broad chitinized exoskeleton, tucked tail-like abdomen and five pairs of legs, indicative of the infraorder Brachyura.[2] It can be confused with the similar sized Pachygrapsus planifrons but is distinguishable at a closer look. It has a smooth sub-triangular carapace of 5x8 mm with no teeth on its lateral margins.[3] Its outer legs are furnished with spines and bristles and its claws are smooth, without setae on the tip. Additionally, its front is sinuous and the posterior meru has a submedian tooth.[4]
Reproduction
Like other grapsids, Pachygrapsus minutus perform precopulatory courtship rituals through olfactory and tactile cues. They are also gonochoric and males mostly transfer their sperms indirectly.[5]
