Tantine

The tantine (English pronunciation: tæntiːn) is a hybrid born from mating a female tuna with a male killer whale. It is not known to Muggles and was only mentioned in the season 3 episode Weirder Fishing.

Diet
The Tantine's diet consists mainly of crabs, lobsters, clams, and fish, such as trout, salmon, cod, and pompano.

Length
The Typolline Tantine (skipjack tuna and orca) is usually about 5 feet long. The Lartight Tantine (bluefin tuna and orca) is commonly around 4 to 4.5 feet long, although there have been reports of some up to 7 feet long. The Vorvtantine (albacore tuna and orca) is rarely more that 3 feet long.

As food
Many wizards use the tantine as food, mainly in the British Isles, the United States, and France. They can be caught by purse seine or gillnets, by weirs and fish traps, or by rods.
