Sesarmine Crabs
Sesarmine
Family Grapsidae

Order Decapoda


Crabs of this subfamily are the most common crabs in mangroves and muddy areas throughout the world. They are ecologically important, being one of the key consumers of mangrove leaves which usually do not decompose easily.

All sesarmines have a reticulate (net-like) pattern on the sides of the shell (next to the rnouthparts) which help to recirculate the water in the gill chamber so that they can breathe atmospheric oxygen. Two common genera are Episesarma and Chiromantes. (Body widths vary from 1-6cm).
