Drawing by Owen Burnham
"Gambo" is the name given to a carcass of an unidentified large marine animal that was reportedly washed up on Bungalow Beach in The Gambia.
The carcass of the Gambo was reported to have been discovered by 15-year-old Owen Burnham and his family on the morning of June 12, 1983. Owen, a wildlife enthusiast, decided to take measurements and then make sketches since he did not have a camera at the time. According to later testimony, he did not think to take a sample until after he realized he could not identify it in any books. According to Owen, local villagers called it a "dolphin", but that was likely only because of the superficial similarity.
The carcass was later decapitated by local villagers, and the head was sold to a tourist. Its body was then buried and attempts to relocate it have failed.
After Owen mentioned the carcass in a newspaper article three years after the event, it caught the attention of cryptozoologist Karl Shuker who requested more information on the carcass. According to Owen, the carcass showed little or no signs of decomposition and measured around 15 feet (4.6 m) in length. The coloration was brown on top and white below, and the skin itself was smooth. The most specific measurements were taken on the head, which was 4.5 feet (1.4 m) in length. It had a beak measuring 2.5 feet (0.76 m) long, 5.5 inches tall, and 5 inches (130 mm) wide with 80 uniform and conical teeth. A small pair of nostrils were present at the tip of the beak. The somewhat domed head measured 10 inches (250 mm) tall and 1-foot (0.30 m) wide, and had small eyes. The front pair of flippers measured 1.5 feet (0.46 m) long by 8 inches (200 mm) wide. One of the rear flippers was badly damaged and nearly torn off, revealing some intestine. The waterlogged and bloated body was around 6 feet (1.8 m) long with a 5-foot (1.5 m) girth. No fin was present on the top of the animal. The tail was long and pointed, and measured around 5 feet (1.5 m) in length.
There has been a great deal of speculation as to what the carcass could have been in life. Some, such as paleontologist Darren Naish, question whether the carcass ever existed in the first place. Naish expresses doubt that the carcass was real, and finds it suspicious that no sample was taken. He did speculate that if real, it could be a marine-adapted monotreme that originated in Zealandia. Cryptozoologist Chris Orrick proposed that it was a severely mangled Shepherd's beaked whale that was twisted so that the dorsal fin and genital slit lined up, giving the appearance of a torn off limb. Loren Coleman and Patrick Huyghe speculated that it may be an unknown form of Beaked Whale.
"Gambo" has been connected to many sporadic reports of crocodile-like sea serpents.
