Description: A large active brittle star with short straight arms and a large disc. Colour varies from dull grey-brown to sandy-orange. The disc is patterned with obvious plates. There are well-developed arm combs with about 30 fine papillae and 3 arm spines. The proximal ventral arm plates are separated by paired holes or indentations. Disc 30mm., arms 3.5x disc diameter.
Habitat: Lives on the surface of sand or muddy sand, occasionally burrowing shallowly. Moves rapidly on being disturbed, by a swimming action.
Distribution: Found all round the British Isles from low tide mark to 200m at least.
Similar Species: Small specimens could be mistaken for other Ophiura species. Ophiura sarsi is equally large but the outer arm combs have only 9-12 rather broad papillae.
