Hiena
Hienas are carnivores from medium to grand size being in a high position in the food chain; except the wolf of land that eats insects. his head is big in comparision with this body, with ears relatively large with a round shape, and powerful shaw muscles. the back legs, stongly muscled, they are shorter than the front legs, which gives an assimetrical look to the animal. Altough they are great hunters, most of his meals is made of carcass that find and steal from other animals. Hienas are not velocity runners, but they are resiliant and they can persute a prey for several miles. They theeth are made of 32 to 34 strong theeth and are adapted to chew bones. They digest system is well trained to the digestion of bones and other hard parts of their preys. this eficient to use all the nutrients of a carcass as advantage is one of the reasons to the group success- 
in which the mere running forms, with adapted dentition to the consumption of soft parts, they had disappeared for the ecological competition with the dogs family. except the land wolf, that he is solitary, hienas have nocturnal habits, although they can promptly be active of day.

The hienas remember a little the dogs, but they are more related to the cats. They societies are dominated by the females, what it is not common between mammals, and the females have very high levels of aggressiveness, generating masculine hormones, what in deed intervenes with the procreation. Even the young are very aggressive and it is common they kill themselves. The hienas are born with the open eyes and teeth entirely formed.

They live in clans until fourty animals. They usually hunt wolfs and rarely attack in ambush as the lions. The force of the jaws of the hiena is fantastic, crashing good part of the bones of the victims.
