Genus
Common name: Pizza Anemone
Scientific name: Cryptodendrum
Cryptodendrum, commonly known as the Pizza Anemone or Adhesive Sea Anemone, is a genus of sea anemones that are popular in the reefkeeping hobby for their unique appearance and behavior. These anemones are known for their large, flat, and colorful oral discs that resemble a pizza, which is where they get one of their common names. They have a sticky foot that they use to adhere to surfaces and can often be found attaching themselves to rocks or glass in an aquarium. Cryptodendrum species are symbiotic with clownfish, which can take refuge among their tentacles for protection.
