(From delawareonline.com)- The 400-pound carcass of a rare deep-water fish washed ashore at 26th Street, apparently killed by the propeller of a large boat.Ocean City lifeguards found the ocean sunfish with four parallel slices to its body, with part of its head also missing from a propeller strike, said Beach Patrol Capt. Butch Arbin. The ocean sunfish, so nicknamed for its common basking near the surface while on its side, can grow up to 11 feet long and 3,000 pounds. It lacks a typical tail and appears to be one enormous fish head. It propels itself through the water with long, thin dorsal fins that extend up and down from its body. When its top fin breaks the surface, it can be mistaken for the dorsal fin of a shark.
