In August 2011 an unidentified animal corpse was discovered by a road in Douglas County, Minnesota. It had five claws on each paw, tufts of black hair and canine characteristics. However its ears were 'humanlike' as described by one onlooker and although a hairless wild dog was suggested, the back legs were entirely to short and bowed. Theories were put forward of it being a mythical chupacabra, to government animal testing, to a domestic dog.
The Shunka Warak'in is an animal mentioned in American folklore that is said to resemble a wolf, a hyena, or both. According to cryptozoologist Loren Coleman, shunka warak'in is an Ioway term meaning "carries off dogs." Coleman suggested that the creature was some animal unknown to modern sources. An animal shot in 1886 by Israel Hutchins on what is now the Sun Ranch in Montana has been suggested by Coleman as an example of this mysterious creature.
The wonders of evolution: Tongue-eating louse (Cymothoa exigua). This parasite enters the fish's mouth (Lutjanus sp.), clings to the tongue's base and extracts all the blood until the tongue atrophies.. Then it replaces the fish's tongue by attaching its own body to the muscles of the tongue stub, and starts to feed on what the host eats; the fish can live normally, and there are even studies around the benefits that he could receive from this parasite. There are no risks to humans.
