The carapace is generally smooth and may exhibit various patterns and coloration depending on the species and individual. Their chelipeds (claws) are usually robust and asymmetrical, with one claw often larger than the other.

• Habitat: They are primarily marine organisms, favoring habitats with ample shelter, such as crevices, boulders, and coral formations.

• Diet: Etisus crabs are generally considered omnivores, feeding on a variety of organisms including algae, small invertebrates, and detritus.

• Distribution: The genus has a wide distribution across the Indo-Pacific region.

Taxonomy:

Etisus is a well-established genus within the Xanthidae family. The exact number of species within the genus may vary depending on taxonomic revisions.

Ecological Role:

Etisus crabs play a role in the marine ecosystem as both predators and prey, contributing to the overall biodiversity and ecological balance of their respective habitats. They also contribute to nutrient cycling through their feeding activities.
