The Captain Hanna’s Fish is an odd, eellike fish, reported North Atlantic Ocean ( Gulf of Maine). Serpentine. Length, 25 feet; 10 inches thick at the largest part. Darkish slate color on top, grayish-white below. Flat head that extends over a small mouth with sharp teeth. Prominent gill slits. Two small, rayed pectoral fins and a triangular rayed dorsal fin behind the head. A caudal fin extends around the tail. In August 1880, Capt. S. W. Hanna caught a fish of this description off New Harbor, Maine, but discarded it because it had torn his net.
- Unknown species of elongated shark, perhaps a large form of the Frilled shark (Chlamydoselachus anguineus), suggested by Bernard Heuvelmans. The Frilled shark grows to over 6 feet in length and lives in deep waters near the sea floor, primarily in the eastern Atlantic, though three individuals have been recorded in the western Atlantic. It is the only shark to have a mouth that opens at the tip of the snout. However, sharks do not have rayed fins. Larger varieties may exist. David Stead examined the skull and vertebrae of a 12-foot fish that washed up in the harbor at Sydney, Australia, in August 1907 and identified it as a Frilled shark, though double the length of the largest known specimens.
- Unknown species of bony fish, by Ben Roesch, based on its lack of pelvic fins, and the position of the dorsal fin.
