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).
How big is a wolfâs track? The size of a wolfâs track is dependent on the age and size of the wolf, as well as the substrate the track was made in. A good size estimate for a gray wolfâs track size is 4 1/2 inches long by 3 1/2 inches wide. In comparison, a coyoteâs track will be closer to 2 1/2 inches long by 1 1/2 inches wide. Only a few breeds of dogs leave tracks longer than 4 inches (Great Danes, St. Bernards, and some bloodhounds).
