Brittle stars occur in all the world's oceans from the deep sea to intertidal zones, and including salt and brackish polar areas, temperate, and tropical waters.

The region with the highest species richness of brittle stars is the Indo-Pacific region with species at all depths. The Arctic has the lowest number of species: Brittle stars (Ophiuroidea) are a group of echinoderms that resemble starfish.

There are about species of brittle stars alive today and most species inhabit marine habitats with depths greater than feet. There are a few species of shallow water brittle stars. These species live in the sand or mud just below the low tide : Laura Klappenbach. Brittle stars or ophiuroids are echinoderms in the class Ophiuroidea closely related to crawl across the sea floor using their flexible arms for locomotion.

The ophiuroids generally have five long, slender, whip-like arms which may reach up to 60 cm (24 in) in length on the largest m: Animalia. "Brittle Stars " was the first of Lichen's "Uncommon Field Guide" series I discovered. They are all uncommonly delightful to poke into.

Habitat. Today, brittle stars are almost omnipresent in the world’s oceans. They are found in virtually all habitats, from the intertidal zone down to depths of more t feet (7, m).
