Etisus
Etisus is a genus of crabs in the family Xanthidae, commonly known as “mud crabs”. They are found in tropical and subtropical waters of the Indo-Pacific region, including the Red Sea, the Indian Ocean, and the western Pacific Ocean.
Common Names
Crabs belonging to the genus Etisus are commonly known as "mud crabs" due to their preference for muddy and sandy substrates. However, specific species may have additional common names based on their geographic location or appearance. For example, Etisus laevimanus is sometimes called the "smooth-handed mud crab".
Characteristics
Etisus crabs typically have a carapace that is oval-shaped and flattened, with a smooth or slightly granular surface. They possess long and slender legs, with the first pair of legs being modified into powerful claws. The color of Etisus crabs can vary depending on the species and their environment, ranging from brown or grey to reddish or orange.
Environments
Etisus crabs are commonly found in intertidal zones, estuaries, and mangrove forests. They prefer muddy or sandy substrates with abundant organic matter, which serves as a food source. They can also be found on coral reefs and seagrass beds. Etisus crabs are often found burrowing in the sediment, which provides them with shelter and protection from predators.
