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.

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]).
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.
Ophiura ophiura is an active brittle star, moving with a jerky swimming action of its legs and sometimes burrowing. [2] It is a filter feeder, feeding on a wide range of food, [1] but also a bottom-feeding carnivore and detritivore. [7] It can regenerate its arms if they are damaged or torn off. [7] Sexual reproduction takes place during the ...

Ophiothrix is a large genus of brittle stars (Ophiuroidea) found in oceans worldwide from tropics to Arctic and Antarctic regions. At present a total of 93 Ophiothrix species have been recognized. It is considered as one of the most interesting genera because of the presence of its brilliant colors and associations with coral and sponges as well.
