Role WHAT DO THEY LOOK LIKE?
Arms radiate around a central disc. Small feet beneath the arms enable movement. Colour, arm count and dimensions vary; silhouette alone cannot identify a species.WHERE DO THEY LIVE?
Some move over rock and coral; others use sediment. The film shows sea stars on the reef but does not measure their depth.WHAT DO THEY EAT?
Diets differ greatly. Some consume biofilms and organic debris; others capture animals. A single diet cannot be assigned to the entire group.GO FURTHER WITH AMIGANSEAU
