Description edit

These starfish have between 6 and 18 long, attenuated arms which they use for suspension feeding.[3] Other characteristics include a single series of marginals, a fused ring of disc plates, the lack of actinal plates, a spool-like ambulacral column, reduced abactinal plates, and crossed pedicellariae.[4] They are 40 times the size of disk radius and have 7–20 flexible spiny arms.[5]

Distribution edit

Brisingida occur in a number of deep-sea locations, particularly in the Caribbean and New Zealand.[6]
