How can you tell if a brittle star is dying?

Brittle stars are sea star cousins that bury themselves for protection, leaving an arm or two free to catch bits of food. Sometimes this attracts a hungry fish but fortunately, a star can’t be tugged out by the arm. The arm snaps off, and a new one grows from the stump.

Can brittle stars regenerate?

Brittle stars (class: Ophiuroidea) are the most diverse group of echinoderms comprising over 2000 species with a global distribution [28, 29]. Adult brittle stars are able to regenerate their entire arms, making them an appealing system for studying regeneration of adult structures.
