Hyenas
Thanks to the film, The Lion King, hyenas have gotten a bad reputation as being low on the list of intelligent animals. However, they are actually very smart. According to scientists, hyena are able to assess the number of attackers around their territory and will react aggressively if they know they outnumber their enemies. Hyenas have shorter hind legs compared to their front legs, which gives them an advantage when it comes to endurance running. They also have a very strong bite which can crush bones easily.
