Tropical sea fans

Distribution : A group found in several seas, including Red Sea and Raja Ampat reefs. Exact distribution depends on species.

Sea fans add a vertical dimension to attached reef life. This group guide presents the colony filmed in the Red Sea; depths vary by taxon and cannot be reduced to one interval.

WHAT DO THEY LOOK LIKE?

The branching colony consists of polyps with eight feathered tentacles, supported by an axis and skeletal elements whose structure varies. Sea fan denotes a colonial form within octocorals here, not a single species.

WHERE DO THEY LIVE?

Colonies occupy hard surfaces under varied water-flow conditions. Depths and ecological requirements depend on the taxon; no uniform numerical range is assigned to this group without species-level identification.

WHAT DO THEY EAT?

Polyp capture of zooplankton and organic particles connects water-column resources to attached animals. Branching forms increase interception area without implying identical feeding in every species.
