Amphiuridae (commonly called long-armed burrowing brittle stars [2] or burrowing brittle stars) are a large family of brittle stars of the suborder Gnathophiurina.Some species are used to study echinoderm development (e.g. Amphipholis kochii [3] and Amphioplus abditus [4]) and bioluminescence (the dwarf brittle star, Amphipholis squamata [5] [6]).
Plate of brittle stars from the Kunstformen der Natur from Ernst Haeckel (1904) Second plate of brittle stars from Haeckel. Between 2,064 [11] and 2,122 species of brittle stars are currently known, but the total number of modern species may be over 3,000. [12] This makes brittle stars the most abundant group of current echinoderms (before sea ...
This brittle star has a circum-boreal distribution. In the northern Atlantic Ocean it is common around Iceland, Spitzbergen and Norway southwards to the North Sea.On the eastern coast of North America its range extends from Greenland southwards to Long Island, and in the Pacific Ocean, its range stretches from Japan and the Bering Sea southwards to California.

Ophiothrix suensoni, Suenson's brittle star or the sponge brittle star, is a species of marine invertebrate in the order Ophiurida. It is found in the Caribbean Sea and Gulf of Mexico. It is included in the subgenus Acanthophiothrix making its full scientific name Ophiothrix (Acanthophiothrix) suensoni. [1]
Ophiocomella alexandri, known as Alexander's spiny brittle star or banded brittle star, is a species of marine brittle star. It was first described to science by Theodore Lyman in 1860. [ 1 ] Lyman states in his description that the animal is named for his friend, Alexander E. R. Agassiz , the son of Lyman's mentor, Louis Agassiz .
The banded brittle star utilizes different methods of feeding depending on the size of a given food particle; if the particle is relatively large, the brittle star grasps it with the tip of its arm and coils its arm to bring it to the mouth, whereas if the particle is relatively small it uses its elongate tube feet to transport food to its mouth.

Ophiothrix fragilis is a species of brittle star in the order Ophiurida. It is found around the coasts of western Europe and is known in Britain as the common brittle star. [3] [4] It is also found along the coast of South Africa where it is known as the hairy brittle star. [5] [6]
