African wild dog packs can have up to 40 members. Canine packs are led by an alpha animal. Sometimes, only the alpha male and female are allowed to mate.
Some scientists believe that meat-eating dinosaurs such as allosaurs hunted in packs, though there is some dispute about this. Though the fossilized bones of these dinosaurs have been found together, these animals may have simply been fighting each other over a kill.
Mules are a bit of a special case for equines because a group of mules is called a pack as opposed to a herd, as is the case for horses, donkeys and zebras. Mules, the result of cross-breeding male donkeys with female horses, have long been used as pack animals. As with many hybrid animals, mules are sterile because the chromosome count of their parents is different. Mules are prized by humans because they can be as strong and fast as horses but are tougher.Learn more about Zoology

Animals that estivate include snails, crocodiles, hedgehogs, tortoises, birds and lungfish. Estivation is the process by which animals enter a state of dormancy during hot times of year to conserve energy. In order to estivate, animals find places that are cooler than the surrounding air, such as underground burrows or holes in tree trunks. Hot and dry conditions, not a lack of food, usually cause animals to estivate.Full Answer >
