Basket it is stars are a group of brittle stars. They are treated as a suborder Euryalina[1] or order Euryalida[2]. Many of them have characteristic many-branched arms. They generally live in deep sea habitats.The life span in the wild is up to 35 years. They weigh around 11 lbs, or 5 kg. Like other echinoderms, basket stars lack blood and achieve gas exchange via their water vascular system.
The basket stars are the largest ophiuroids with Gorgonocephalus stimpsoni measuring up to 70 cm in arm length with a disk diameter of 14 cm[3].
The fossil record of this group is rather poor and only dates back to Carboniferous[4]. Basket stars are divided into the following families:
