The Earth's freshwater is even rarer. For humanity to thrive, or even exist, we need to sprinkle that teeny bit of fresh water in the right places, at the right times and in just the right amounts, Gallo said. Here's how Earth's freshwater is spread around the globe: 1  70 percent of freshwater is locked in ice caps.
Believe it or not these are not the first lines of terrible jokes, but real scientific questions with real living answers. Hybrid animals are the offspring produced when two animals of closely related â but different â species breed.The young produced will usually not be fertile, and so hybrid species are not normally seen in the wild. In order for more of these hybrid animals to exist the original two species must be cross-bred again.elieve it or not these are not the first lines of terrible jokes, but real scientific questions with real living answers.

Meerkats, Mongoose & Otters. These are some of the most charismatic animals that you will see at the zoo. Otters can be cute and playful, but in wild they're known as the 'river wolf' because of their razor sharp teeth and muscular body that helps them hunt and eat fish. Mongooses are also small carnivorous mammals. Despite not being closely related, they look quite similar to weasels, live in similar climates and both burrow underground. We have two species of otter and four species of mongooses, including the dwarf mongoose and the fascinating meerkats.
