The Hook Island Sea Monster, also known as the tadpole creature, is the name given to a 90-foot sea monster sighted off the coast of Hook Island. It resembles a giant tadpole, has a gaping mouth with small teeth and eyes placed on top of it’s head.
The monster was sighted by Robert Le Serrec and his family in 1964 when it moved towards his ship with its mouth open as if to attack. He spotted its tail was injured, probably by a ship’s propeller or by a larger creature. He described that ” It was only when we got to within 20 feet of the serpent that we could see its head clearly. The head was large, about 4 feet from top to bottom, with jaws about 4 feet wide. The lower jaw was flat like that of a sandfish. The skin was smooth but rather dull, brownish-black in color, the eyes seemed pale green, almost white. The skin looked more like that of a shark than an eel. There were no apparent scales. Nor did we see any parasites around. We supposed the flexible tail would have shaken any off. There were no fins or spines, nor were there any apparent breathing openings, although there must have been some. Perhaps we didn’t see them because our attention was focused mainly on the creature’s menacing mouth, the inside of which was whitish. The teeth appeared to be small. A fragment of some dark substance hung from the upper row of teeth, possibly a fish. As the monster was lying on the sandy bottom, we could not see the colour of its belly. The creature was about 90 feet long. Behind the head the body was about 2 feet 4 inches thick and remained that way for about 25 feet, then it gradually tapered into a whip-like tail. The general colour of the body was black with 1 foot-wide brownish rings every 5 feet, the first starting just behind the head. The skin was smooth but dull.” Just as it seemed it would swallow the ship, it swam away. Le Serrec managed to take a few shots before it swam away, never to be seen again.
