If you're including non-mammals, Phil, then oysters are eaten raw, and a Dutch speciality is fresh raw herring. Inuit (previously Eskimo before MPCD - mad political correctness disease - struck) eat seal meat raw, and there is a fairly ghastly Egyptian practice of eating monkey brains directly from live monkeys. Well, dying monkeys, is probably more correct.
(If I remember an awful film on foul things done to animals, the monkey is led under a table where the top opens into two halves, with a hole in the middle. The two halves of the table close, with the hapless monkey's head poking out of the hole, while its body is left dangling underneath. Some sort of gigantic pincers pinch off the top of the monkey's head, and the diners dig into the skull with spoons, scooping out the brains, bloody, warm, and raw. I don't know who thinks these things up, but I wouldn't mind pincing off the top of their head, too.)
Plenty of indigenous tribes from various countries eat their catch of the day raw, whether it's small deer, monkeys, or whatever. The problem is that in dank jungle/rainforest conditions, it's bloody difficult to light fires, and meat would soon go rotten in such conditions, so it's eyes down, look in, and bon appetit!
Steak Tartare (also Steak Tartar, Tartare Steak, or Tartar Steak) is minced raw beef steak with finely chopped raw onions, seasonings, and a raw egg, all mixed together and served usually as a main dish. I've had it a couple of times - the first time it was excellent, the second time it felt a bit greasy, and I didn't finish it.
