They use their stinging tentacles to get food. The tentacles contain stinging cells called cnidoblasts and inside each cnidoblast there is a coiled thread with a barb at the end called a nematocyst. The nematocysts are discharged into prey such as a fish, they paralyze it and then the contracting tentacles bring the fish up to the mouth.
