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).
They all actually run at about the same speed. A Greyhound will sprint at speeds of 39 to 43 MPH for a distance of 440 to 660 yards. A European brown hare can sprint at speeds of 45 MPH for about the same distance as a Greyhound. A racehorse can gallop at speeds of 40 to 50 MPH for 440 yards to 2 miles.
