Father-of-All-the-Turtles : A giant Turtle, one category of Sea Monster identified by Bernard Heuvelmans.


From a Sumatran legend.

Variant name:

Aspidochelone (Greek, “snake-turtle”).

Physical description:

Tortoiselike head. Large, prominent eyes. Wide mouth. No teeth. Medium-length, slender neck. Rounded carapace with a saw-toothed ridge. Large scales on the back. Two pairs of flippers.


Breathes through its mouth, making a whistling noise.


North Atlantic Ocean and the Caribbean Sea.

Significant sightings:

As his three caravels sailed east along the southern coast of the Dominican Republic in early September 1494, Christopher Columbus and his crew saw a whale-sized turtle that kept its head out of the water. It had a long tail with a fin on either side.

On March 30, 1883, the schooner Annie L. Hall sighted what looked like a capsized ship on the Grand Banks (or off the Azores if you go by the longitude provided) in the North Atlantic Ocean. However, it turned out to be a turtle “40 feet long, 30 feet wide, and 30 feet from the apex of the back to the bottom of the under shell.” The flippers were 20 feet long. This report was apparently confused in contemporary newspapers with a more conventional, 100- foot-long Sea Monstersighting that took place in November 1883 by Capt. W. L. Green and
some fishermen off Long Branch, New Jersey.

On March 8, 1955, L. Alejandro Velasco was stranded on a raft off the Gulf of Urabá, Colombia, when he saw a yellow turtle about 14 feet long.

In June 1956, the cargo steamer Rhapsody reported a 45-foot turtle with a white carapace south of Nova Scotia. It had flippers 15 feet long and could raise its head 8 feet out of the water.

On September 13, 1959, Tex Geddes and James Gavin were fishing off Soay in the Inner Hebrides, Scotland, when they saw the head and back of a huge animal approach them until it was only 20 yards away. Its body was 4–8 feet broad at the waterline, and the back was 2 feet–2 feet 6 inches high. They watched it for five minutes, after which it dived and swam further out to sea.

In August 1971, Nessie-hunter Tim Dinsdale discovered a huge, dead turtle in a storage shed in Mallaig on the coast of Scotland not far from Soay. He estimated its weight at 1,500 pounds.

Possible explanations:

(1) The Atlantic leatherback turtle (Dermochelys coriacea coriacea) ranges throughout the North Atlantic from
Newfoundland to the British Isles and can reach a length of 7–8 feet. It has longitudinal ridges on its back but no jagged ridge. It rarely exceeds 800 pounds.
(2) A surviving Archelon ischyros, the largest known turtle, measured up to 16 feet long and 12 feet wide, and may have weighed as much as 11,000 pounds. It lived some 70 million years ago in marine seas of the Late
Cretaceous. Fossils have been found in South Dakota, Kansas, and Colorado.
