Atlantic sea nettles are carnivorous. The diet consists of zooplankton, ctenophores, as well as other jellies. Plankton (microscopic plants and animals drifting in the water) predominate the dietary regimen of the jelly. They tend to also prey upon small crustaceans, comb jellies, and fish eggs and larvae. Nettles also consume young minnows, bay anchovy eggs, worms, and mosquito larvae. Due to the large variety of prey, combined with their highly effective hunting style, C. quinquecirrha seldom goes without something to eat.
