FAQ

Frequently Asked Questions

It is related to starfish (both are echinoderms), but more precisely it is a type of brittle star (ophiuroid) with a distinct, highly branched body plan.

Only in large public aquariums with dedicated deep-sea or cold-water exhibits, as they are delicate and require specific conditions.

It is a suspension feeder, using its network of tiny, coiled arm branches to trap plankton and organic particles from the water.

The name describes its appearance: when it extends its numerous, repeatedly branching arms, they form a rounded shape resembling a basket.
