Appearance and lifestyle:
Sea fans (Gorgonia ventalina) are composed of numerous polyps that grow together in a flat, fanlike pattern. In sea fan colonies, each polyp has eight tentacles, and they spread these out to form a net for catching plankton. An internal skeleton, composed of a scleroprotein called gorgonin, supports the branches while the polyps form a layer over the entire surface. Most sea fans grow to roughly 60 cm in height
Habitat:
Found in the shallow waters of all oceans.
Diet:
Sea fans eat plankton and organic particles.
Threats:
Some threats that sea fans face are storm damage, climate change, pollution etc.
In favourable conditions sea fans can regrow damaged parts.
