Very few animals feed on these jellies since they are covered with stinging cells and have toxic venom. Sea turtles (mainly the leatherback turtle, Dermochelys coriacea), are possibly the best known predator of jellyfish and are regularly seen where jellyfish concentrations are high. Other fish, such as ocean sunfish also prey on jellyfish. One of the biggest predators of jellyfish are other jellyfish, mainly of other species.
In some Asian cultures, some fishermen routinely catch jellies to be dried and sold to restaurants. In Asia, jellies are seen as a delicacy.
