Sea fans are related to soft corals.

They look like small trees, but they are actually colonies of animals (polyps) living together in the shape of a fan.

Each polyp has eight feathery tentacles. 

When the polyps come out to feed they give the “branches” a fuzzy appearance.

Sinuous sea fans are flattened with all the “branches” on the same plane.

Small spider crabs can often be spotted hiding among the branches.
