Brittle stars or ophiuroids are echinoderms in the class Ophiuroidea closely related to starfish. They crawl across the seafloor using their flexible arms for locomotion. The ophiuroids generally have five long slender, whip-like arms which may reach up to 60 centimetres (24 in) in length on the largest specimens. They are also known as serpent stars.

Ophiuroidea contains two large clades, Ophiurida (brittle stars) and Euryalida (basket stars). Many of the ophiuroids are rarely encountered in the relatively shallow depths normally visited by humans, but they are a diverse group.

There are some 1,500 species of brittle stars living today, and they are largely found in deep waters more than 500 metres (1,650 feet) down.

Famous quotes containing the words brittle and/or star:

    Night’s brittle song, silver-thin
    Shatters into a billion fragments
    Of quiet shadows
    At the blaring jazz
    Of a morning sun.
    Frank Marshall Davis (b. 1905)

    I would that we were, my beloved, white birds on the foam of the sea!
    We tire of the flame of the meteor, before it can fade and flee;
    And the flame of the blue star of twilight, hung low on the rim of the sky,
    Has awaked in our hearts, my beloved, a sadness that may not die.
    William Butler Yeats (1865–1939)
