Where You Will See It In Cozumel
Reef tops in the current at Tormentos, Yucab, Paso del Cedral and Las Palmas — much of the swaying Cozumel reef top is sea plume.
Reliable sites: Tormentos, Paso del Cedral, Las Palmas.
Behaviour
A colonial soft coral feeding on plankton. The constant motion of a Cozumel reef top in current is mostly this animal, and it shelters juvenile fish and brittle stars.
Commonly Confused With
- Sea fan — A flat mesh in one plane, not a feathery three-dimensional plume.
- Sea rod — Thick, stiff rods rather than fine feathery branches.
Diving Etiquette And Safety
Do not grab a plume to stop yourself in current. It is an animal, and it is the handhold divers reach for most.
