Ophiuroidea, commonly known as brittle stars or basket stars, are echinoderms with five long, slender, whip-like arms. They have a central disc-shaped body and can range in size from a few millimeters to over 60 cm in diameter. They are typically found in shallow waters, but can also be found in deeper waters. They have a lifespan of up to 10 years and their current population is stable. They have a wide range of colors, including yellow, orange, red, green, and brown. They are usually found on the ocean floor, hiding in crevices or under rocks. They feed on small organisms such as plankton and detritus.
Name Origin: The name Ophiuroidea is derived from the Greek words ophis, meaning "snake," and oura, meaning "tail." This is in reference to the long, slender arms of the organisms in this group, which resemble the tail of a snake.
