Feeding & growth

Food is likely to consist of small planktonic crustaceans, worms, and various invertebrate photograph of cup coral Balanophyllia elegans egesting unwanted food residue consisting, in this case, possibly of some crustacean bitslarvae. The tentacles are well-endowed with nematocyst batteries (as evidenced by the small white spots in the photo) and these are used to capture the live prey and pass it to the mouth. The food is digested in the gastrovascular cavity and undigested wastes released via the mouth to the outside.
