Ophiopsammus Maculata
''Ophiopsammus maculatus'' is a species of brittle star (related to starfish) in the family Ophiodermatidae. The species is a small five-limbed seastar with a round central disk and long, black or red limbs. Its range is New Zealand where it inhabits littoral zone The littoral zone, also called litoral or nearshore, is the part of a sea, lake, or river that is close to the shore. In coastal ecology, the littoral zone includes the intertidal zone extending from the high water mark (which is rarely flood ...s in coastal waters. Etymology ''Maculatus'' comes from the Latin for 'spotted'. The genus name comes from the Greek ''ὄφις'', for 'snake', and ''ψάμμος'', for 'sand'. Presumably, the name is meant to refer to the long arms and the habitat of the brittle star. References Ophiacanthida Marine fauna of New Zealand Animals described in 1869 {{Ophiuroidea-stub ...

Brittle Star
Brittle stars, serpent stars, or ophiuroids (; ; referring to the serpent-like arms of the brittle star) are echinoderms in the class Ophiuroidea, closely related to starfish. They 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 in length on the largest specimens. The Ophiuroidea contain two large clades, Ophiurida (brittle stars) and Euryalida (basket stars). Over 2,000 species of brittle stars live today. More than 1,200 of these species are found in deep waters, greater than 200 m deep. Range The ophiuroids diverged in the Early Ordovician. Ophiuroids can be found today in all of the major marine provinces, from the poles to the tropics. Basket stars are usually confined to the deeper parts of this range; Ophiuroids are known even from abyssal (>6,000 m) depths. However, brittle stars are also common members of reef communities, where they hide under rocks and even w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
