Moha Moha

Moha Moha is a giant turtle/fish reported in Queenland's Great Barrier Reef in Australia.

1890
We have had a visit from a monster turtle fish. I send a sketch of it. It let me stand for half an hour within five feet of it. When tired of my looking at it, it put its large neck and head into the water and swept round seaward, raising its dome-shaped body about five feet out of the water, and put its twelve feet of fish-like tail over the dry shore, elevating it at an angle. Then, giving its tail a half-twist, it shot off like a flash of lightning, and I saw its tail in the air about a quarter of a mile off where the steamers anchor...The jaws are about 18 inches in length; the head and neck greenish-white, with large white spots on the neck, and a band of white round a very black eye... The body was dome-shaped, about 8 feet across and 5 feet high, smooth, and slate-grey in colour. Tail about 2 feet, the fish part wedge-shaped, and fin of chocolate-brown. Then beautiful silver shading to scales size of thumb nail.

This is what the man/woman told after the encounter with it.
