Xantho

Xantho is a genus of xanthid crabs, a family of marine crustaceans. These crabs are known for their generally broad, flattened bodies and often vibrant coloration, though some species can be more subdued in appearance. Xanthid crabs are found in marine environments worldwide, inhabiting a variety of habitats including coral reefs, rocky shores, and sandy bottoms. They are typically benthic, meaning they live on the seafloor.

The diet of xanthid crabs varies depending on the species, but many are scavengers or omnivores. They may consume algae, detritus, small invertebrates, and carrion. Some species are known to have venomous claws, which they use for defense and to subdue prey. However, it is important to note that not all xanthid crabs are venomous, and the level of toxicity can differ significantly.

Reproduction in xanthid crabs follows the typical pattern for decapod crustaceans, involving external fertilization and larval development. The larvae are planktonic, drifting in the ocean currents before settling to the seafloor to metamorphose into juvenile crabs. The size of xanthid crabs ranges from small to moderately large, with some species reaching several inches across their carapace. Their ecological role often involves predation on smaller organisms and scavenging, contributing to the overall health of marine ecosystems.
