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).
Grizzly bears - can reach top speeds of up to 30 mph (48km/h), but they can't maintain that speed for very long. American Black bears - can reach running speeds of up to 25 mph (40km/h). Bears aren't necessarily built for speed, but are capable of running fast when necessary. j.a.
