Deepstar 400 fish

Deepstar 4000 fish

The Deepstar 4000 fish, a cryptid giant of the deep sea, made a singular appearance off the coast of southern California in the Pacific Ocean during a dive in 1966 by the crew of the Deepstar 4000 submersible. It was estimated to measure between 25 and 40 feet (8–12 meters) in length, comparable to some of the largest known living fish and significantly larger than any known bony fish.[1]


In 1967[2], Pilot Joe Thompson (1930 – 2003) and potentially marine biologist Gene LaFond (1909 – 2002) allegedly spotted this fish during a research dive in the San Diego Trough in June 1966, accompanied by instrumentation engineer Dale Good. They had taken the Deepstar 4000 down to approximately 4,000 feet (1,219 meters) to deploy hydrographical instruments on the seabed. While Thompson glanced through the window, he found himself face to face with a massive fish that briefly swam into view. It swiftly passed, stirring up silt from the seabed, before vanishing. The sighting lasted for about 8 seconds.

Thompson and LaFond chose to remain silent for over six months, fearing disbelief. Eventually, they shared their encounter with journalists Paul J. Tzimoulis and Louis Schafer, as well as with cryptozoologist and marine writer Gardner Soule. Thompson also recounted another encounter with a much smaller giant grenadier to Soule. According to Soule, the reactions of the two men were recorded on the submersible's audio log. Thompson claimed that LaFond didn't witness the fish, but LaFond independently stated that he did.

The Deep Star 4000 Submersible

The most striking aspect reported by Thompson and LaFond was the purportedly immense size of the fish, resembling somewhat a sea bass in body shape. It exceeded the size of the 18-foot (5-meter) Deepstar 4000 submersible and was estimated to be between 25 and 40 feet (8–12 meters) long, similar to some whale sharks (Rhincodon typus), but only 5–6 feet (1.5–1.8 meters) wide. In addition to the submersible itself, the pair used the hydrological instruments placed at intervals on the seabed to gauge the fish's length. It featured gill plates, massive 2-foot (60-centimeter) pectoral fins, and a rounded grouper-like tail fin measuring 4–5 feet (1.2–1.5 meters) in height and described as "serrated." Thompson emphasized the unusual tail, likening it to an illustration of a coelacanth's tail. Its eyes, one of which Thompson initially saw, were described as "as big as dinner plates." The skin was dark, mottled with "gray-black" or "brown with grayish white tipping on the fin scales and tail." Thompson was certain it was covered in scales, with those toward the front of the body being the largest, roughly the size of coffee cups.
