description Echinodiscus auritus Overview
Echinodiscus auritus is a species of sand dollar, a type of flat, burrowing sea urchin. Found in the shallow coastal waters of the Indo-Pacific region, this marine animal inhabits sandy sea floors where it buries itself to feed on organic detritus. It is recognized by its distinctive rigid skeleton, or test, which features characteristic paired slots called lunules that aid in feeding and stability in soft sediment. First described in the 18th century, the species is of interest to marine biologists studying echinoderm morphology and coastal benthic ecosystems.
