While the common hippo is not in danger of extinction, the species is threatened by loss of habitat as a result of human encroachment and the continued expansion of the Sahara Desert. Hippos graze on land; they do not eat while in the water and arenât known to graze on aquatic plants. They prefer short, creeping grass and small green shoots and reeds.
8)Grey wolves live an average of 8-10 years, but sometime longer in the wild. Red wolves are usually under 10 years in the wild. 9) Wolves, like all dogs, are coursers and can maintain a speed for a period of time to chase prey (vs. cats which are stalkers and display fast speeds for short distances). Grey wolves can run up to about 50km/h (30mph). 10) The distance they travel depends again on prey availability, but can travel 15-50km a day (10-30miles).
From head to tail, the adult gray wolf measures 36 to 63 inches. This makes the gray wolf a top predator for taking down smaller mammals individually, such as rabbits and beavers, as well as in pack to take down a full-grown deer, elk or moose. The gray wolf has a life span of six to eight years and usually runs in packs of six to 10 animals.
