Giglioli's Whale

Giglioli's Whale, or ''Amphiptera pacifica'', is a purported species of whale observed by
Enrico Hillyer Giglioli
Enrico Hillyer Giglioli (13 June 1845 – 16 December 1909) was an Italians, Italian zoologist and anthropologist.
Giglioli was born in London and first studied there. He obtained a degree in science at the University of Pisa in 1864 and started ...
. It is described to have two dorsal fins, a feature which no known whales have. On September 4, 1867, on board a ship called the ''Magenta'' about off the coast of Chile, the zoologist spotted a species of whale which he could not recognize. It was very close to the ship (too close to shoot with a cannon) and was observed for a quarter of an hour, allowing Giglioli to make very detailed observations. The whale looked overall similar to a rorqual, long with an elongated body, but the most notable difference was the presence of two large dorsal fins about apart. Other unusual features include the presence of two long sickle-shaped flippers and a lack of throat pleats. Another report of a two finned whale of roughly the same size was recorded from the ship ''Lily'' off the coast of Scotland the following year. In 1983 between Corsica and the French mainland, French zoologist Jacques Maigret sighted a similar looking creature. Although it has not been proven to exist, it was given a "classification" by Giglioli. The whale may have been a genetic mutation. Given the species' alleged size and attributes, it is extremely doubtful such a species would not have been taken (and reported) by modern commercial whalers, bringing into doubt its very existence.

. It supposedly possesses two dorsal fins, much like Giglioli's Whale. One is near the head, where the neck would be on terrestrial animals, and the other is farther back than the dorsal fin of any other dolphin. These have a somewhat large size, and are black with large white blotches. Michel Raynal suggested it may have been misobserved somersault behavior (with the first "fin" being a flipper and the second being a fluke), but dismissed it as unlikely.

stuck on its head. Markus Bühler pointed out that one dolphin's deformed jaw curiously resembles the oddly placed fin or "horn" of the rhinoceros dolphin. Supernumerary dorsal fins are apparently a genuine mutation; however, none have turned up a considerable distance from where the dorsal fin should be positioned, let alone on the head. Raynal and Sylvestre (1991) argued that since Quoy and Gaimard observed multiple individuals exhibiting the morphology, a distinct species, ''Cetodipterus rhinoceros'', would be more probable than a pod of disfigured individuals. Another argued hypothesis is that that pod was part of an inbred population, which led to the mutation. Another possibility is that Quoy and Gaimard observed specimens which were neither deformed nor members of an unknown species or population, but rather misidentified a pair of beaked whales that, by perspective, appeared to be one single creature.

sorted the confusion out and determined that there were no high-finned sperm whales and that there was only one species of sperm whale in one genus. Sibbald was at least aware of the existence of killer whales and beluga whales, and he noted that he did not directly witness the whales above so the report of the shape of their heads and some other features is unclear. Furthermore, it has also been pointed out that the high-finned ''Physeter'' species listed by Linnaeus may have seen killer whales, and that his use of the scientific name ''Delphinus orca'' may have been for
