Basket stars, sometimes referred to as a Shetland Argus, are a taxon of brittle stars. They are treated as a suborder Euryalina or order Euryalida. Many of them have characteristic repeatedly branched arms. They generally live in deep sea habitats. However, they have been observed near 15m or less in Plettenberg Bay, South Africa. In the wild they may live up to 35 years. They weigh up to 5 kilograms (11 lb). Like other echinoderms, basket stars lack blood and achieve gas exchange via their water vascular system.
