As they grow, these reefs provide structural habitats for hundreds to thousands of different vertebrate and invertebrate species. The skeletons of stony corals are secreted by the lower portion of the polyp. This process produces a cup, or calyx, in which the polyp sits. Why Gorgonia is known as sea fan?
The skeleton is composed of calcite and gorgonion, a collagen-like compound. The calyces in which the polyps are embedded are in two rows along the branches. Many of the smaller branches are compressed in the plane of the fan, which distinguishes this species from the Venus sea fan (Gorgonia flabellum).
Do Gorgonians have Zooxanthellae?

What is the other name of Gorgonia?

How do sea fans eat?
Feeding. Sea fans use their polyps to trap small food particles, such as phytoplankton and bacteria. The sea fan usually grows so that it is best oriented for the prevailing water current to flow over the polyps for food to be easily trapped.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
