The Dusky Dolphin is a small species of dolphin that is found inhabiting the cooler waters along continental shelves throughout the southern hemisphere. This distinctive looking cetacean is closely related to other large marine animals including other dolphins, porpoises and whales but despite their fish-like appearance Dusky Dolphins are true mammals that both breathe air in and out of their lungs and also suckle their young on milk produced by the mother's mammary glands. Dusky Dolphins are widespread throughout the southern hemisphere with three species being recognised that have been grouped by their geographical range, with one found off the coast of South America, one near South Africa
There are 9 different species of howler monkey, found dispersed throughout the tropical jungles of South America. The howler monkey is one of the largest species of monkey found in South America with some howler monkeys growing to nearly a meter long.
Despite their large size, howler monkeys weigh less than 10 kg which allows them to move with more agility through the high trees and lets the howler monkeys hang from branches by their tails when picking fruit.
The howler monkey is thought to have to loudest call of all the primates in the world with some howler monkeys being able to project their howling voices for up to a few miles! Howler monkeys move in troops of around 18 howle

The Arctic Fox is a small white fox native to the Arctic regions of the Northern Hemisphere. The Arctic fox is commonly found in the colder parts of Canada, Alaska, Northern Asia and Europe. The Arctic fox is also commonly known as the Snow fox or the White fox due to the fact that the Arctic fox has white fur and spends a great deal of time in the cold snow.
The Arctic fox has extremely thick winter fur, which is apparently the warmest fur of all the mammals. The thick fur of the Arctic fox is definitely an essential for the Arctic fox to continue dwelling successfully in the harsh Arctic terrain where temperatures regularly fall below minus 40 degrees Celsius.
