Brittle star crawl across the seafloor using their flexible whip like arms which can reach a length of 60cm in the larger specimens.

Different types of brittle star live in an abyssal depth of deeper than 6,000 metres. They are common in reef communities where they hide under rocks.

They are generally scavengers but may also prey on small crustaceans or worms. Brittle star become fully grown in three to four years and can live up to five years. They, like lizards, can shed their arms to escape predators then regenerate them; it can also regenerate its stomach.
