description Echinometra mathaei Overview
Echinometra mathaei is a species of sea urchin widely distributed across the Indo-Pacific region, where it primarily inhabits shallow coral reefs. Originally described by Henri Marie Ducrotay de Blainville in 1825, this marine invertebrate is specifically known for its ability to bioerode coral. It uses its sharp teeth and spines to excavate burrows within the hard reef structure, which helps protect it from predators and wave action.
