|Medusafishes are medium to large deepwater fishes often found at the edge of the continental shelf, in submarine canyons and near oceanic islands. They have been found in depths of over 5200 m (17,000 ft). They are a deep-bodied wide fish though somewhat laterally compressed. The larvae and young can be found near floating debris or around jellyfishes, even inside the medusa (bells) of the jellyfishes, thus the name medusafishes. They use the jellyfishes for protection and to scavenge the leftovers from jellyfish meals. They also eat jellyfishes. There is not a directed fishery for the fishes in this family, but they are known to be an excellent food fish.
