About the ocean sunfish
The ocean sunfish is one of the strangest things you can see from a boat. It is a huge flat disc of a fish that looks like a head with no tail, with tall dorsal and anal fins and a small mouth. It is often seen basking at the surface in open water. Mature fish are usually several hundred pounds, according to British Sea Fishing, and Wikipedia gives adults of 247 to 1,000 kg and about 1.8 m long. It feeds mainly on jellyfish. In Britain it is a summer visitor, according to the Wildlife Trusts, and British Sea Fishing says it is seen more often off southern England as the sea warms. So on a boat trip, a sunfish is a sighting rather than a catch, and the sources give no angling method. It is listed as Vulnerable by the IUCN and is not commercially caught in Europe. If you do see one lying on the surface, leave it alone and enjoy the view. The British boat-caught record stands at 108 lb, from off Saundersfoot in 1976.
