Blue whale

Blue Whale Classification and Evolution The Blue Whale is an enormous species of whale that is found in subtropical and polar waters worldwide. With some individuals growing to more than 100ft long, the Blue Whale is not only the largest animal species in the world but it is also thought that it could be the biggest creature that has ever existed. There are three recognised sub-species of the Blue Whale which are the Northern Blue Whale, the Southern Blue Whale and the Pygmy Blue Whale that despite its name, still reaches an average length of 24 meters. Although their enormous size and slow-maturing nature has meant that the world's Blue Whale population has never been greatly numerous, they have drastically declined in numbers due to having been hunted by Humans particularly over the past 100 years. Blue Whales are now legally protected and despite one not having been deliberately caught since the 1970s, their numbers are continuing to fall in much of their natural range.

Humpback whale

The humpback whale is one of the bigger species of whale with the average adult humpback whale measuring more than 15m long (thats still about half the size of the blue whale). Humpback whales are found in all of the main oceans worldwide, but the humpback whales tend to stay in three main herds, the Atlantic, the Pacific and the Indian Ocean herds. There were once thought to be less than 15,000 humpback whale individuals left in the wild, with the humpback whale population declining by nearly 90% when whale hunting became popular with humans, meaning that the humpback whale was on the verge of extinction. Since new whaling laws have been put into place the humpback whale population has been allowed to grow again and today there are believed to be roughly 80,000 humpback whale individuals left in the wild.

Hawk

Hawks are a group of medium-sized diurnal birds of prey of the family Accipitridae. Hawks are widely distributed and vary greatly in size.

Hummingbird

A very small, brightly coloured bird with a long, thin beak, whose wings move very fast and make a humming noise.

Iguana

Iguana is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described in 1768 by Austrian naturalist Josephus Nicolaus Laurenti in his book Specimen Medicum, Exhibens Synopsin Reptilium Emendatam cum Experimentis circa Venena. Two species are included in the genus Iguana: the green iguana, which is widespread throughout its range and a popular pet, and the Lesser Antillean iguana, which is native to the Lesser Antilles and endangered due to habitat destruction.

Jackal

The jackal is a medium sized member of the dog family, originally found in Africa, Asia and southeast Europe. There are four main species of jackal with these jackal species being the golden jackal, the side-striped jackal, the black-backed jackal and the Ethiopian wolf jackal. The golden jackal is the most northernly species of jackal and can be found as far east as Burma in Southeast Asia. Jackals are generally found in packs of roughly between 10 and 30 jackal individuals. Jackals use their large group numbers to their advantage and work together in a similar way to a wolf pack to both occasionally hunt for food but more so that the jackals can protect one another.

Indri

Indri Classification and Evolution The Indri is a large species of Lemur found only on the secluded island of Madagascar. The Indri evolved in the same way as every other Lemur, from smaller individuals that came to the island from Africa around 50 million years ago. Due to the fact that there were no other primates to compete with, Lemurs soon adapted to live in a variety of habitats, producing a diverse range of different species. Locally, the Indri is known as the babakoto which means little father or ancestor of man. As the native people believe that the Indri (with its lack of visible tail) resembles their ancestors, their is a certain taboo over consuming it, meaning that the Indri does receive some protection in parts of their native environments.

Cougar

The cougar is native to the Americas, particularly south America and western North America and is often known by other names such as mountain lion, puma and panther. Cougars can be found mainly in the mountain regions of Canada and Mexico, but as the name cougar is often used to describe an un-spotted leopard, cougars are also found in Asia and Africa. The cougar is the fourth biggest feline in the world behind the lion, tiger and jaguar, making the cougar the second largest cat in the Americas. The cougar has longer back than front legs and a long heavy body.

Cottontop tamarin

The Cottontop tamarin is a small species of monkey found in the forests of South America. The Cottontop tamarin was named because of it's elegant white fur that flows over it's head and shoulders. The cottontop tamarin is found in tropical forest edges and secondary forests from Costa Rica to north western Columbia where the cottontop tamarin spends the majority of it's life in the trees. Cottontop tamarins are among the smallest of the primates with a body length of 17 cm and tail length of 25 cm. The forelimbs of the cottontop tamarin are shorter than the hind limbs, and unlike other monkeys the thumb of the cottontop tamarin is not opposable and it does not have a prehensile tail.

Cow

A large animal kept on farms to produce milk or beef. Cow are raised as livestock for meat (beef and veal), as dairy animals for milk and other dairy products, and as draft animals (oxen or bullocks that pull carts, plows and other implements).

Crab eating macaque

The crab-eating macaque is a medium species of monkey, found in the tropical and sub-tropical forests and jungles throughout South-East Asia. The crab-eating macaque differs from other macaque species in the fact that the crab-eating macaque has a long tail which is about the same length as it's body. The crab-eating macaque is widely dispersed across the South-East Asian jungles and are found in a variety of different habitats. The crab-eating macaque generally settles in areas that are close to water over a wide range of habitats including lowland forests, tropical jungles and mangroves.
