Gymnangium [Gymnangium]
Description
Gymnangium is a genus of the Lafoeidae family, notable for its diverse and often complex colony structures. The colonies can range from feather-like to bushy formations, with polyps that are not encased in protective coverings, distinguishing them from some related genera. These polyps feed by capturing planktonic organisms with their tentacles. Gymnangium species are found in oceans around the world, from shallow coastal waters to the deep sea, where they inhabit various substrates and contribute to the marine ecosystem's complexity.
