A “sea-monster” reported by the officers and crew of H.M.S. Osborne in calm waters off northern Sicily, June 2, 1877. These sketches were produced by Lt. Haynes, a witness, for the London Graphic.

A Lt. Osborne told the New York Independent that the row of fins pictured in the first sketch was 30 to 40 feet long. The second sketch, he said, shows the creature “end on,” depicting only the head, which was “bullet-shaped and quite six feet thick,” and flippers. Osborne estimated that the animal was 15 or 20 feet wide across the back, and “from the top of the head to the part of the back where it became immersed I should consider about fifty feet, and that seemed about a third of its whole length.”

“Thus it is certainly much longer than any fish hitherto known to the zooelogists,” concludes the Independent, “and is, at least, as remarkable a creature as most of the old wonder-makers ever alleged.”
