Description

These starfish have between six 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

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

gollark: If you can do the same thing with less code and there's not a significant loss, that is a *good* thing.
gollark: Rust *good*, however Python better in this situation.
gollark: Python has more library support for the various useful tasks I need.
