The ocean sunfish is a large, flat fish that spends most of its time in deep water feeding mainly on jellyfish. Sunfish often have many species of copepods, small crustaceans that bury their heads into the soft tissue of the sunfish. Sunfish will swim to the surface of the water and lie sideways allowing seabirds to eat the copepods from their skin. Match the organism to the correct description of how each organism is related to the sunfish.
Seabirds
Mutualism
Jellyfish
Predation
Copepods
Parasitism
