Although they have the general shape of a fish, Humpback Whales are mammals. They are warm blooded and breath air. Humpback whales can easily be identified by their stocky bodies with obvious humps and black dorsal coloring. The fluked tail, which it lifts above the surface in some dive sequences, has wavy trailing edges. Humpbacks are powerful swimmers, and they use their massive tail fin, called a fluke, to propel themselves through the water and sometimes completely out of it. These whales, like others, regularly leap from the water, landing with a tremendous splash. Scientists aren't sure if this
They are experts at escaping predators like the wolf, bobcat, or lynx. When a predator chases it, the rabbit will quickly change direction. They are also good swimmers and will jump in the water to make an escape. Polar bear Polar bear is the largest carnivore on land. The polar bear's fur is clear, not white. Light reflects off the fur and makes it look white. Their teeth and claws are very sharp so they can catch their prey easily. They hunt and eat seals, whale and walrus carcasses. In the summer they also eat lemmings, arctic foxes, ducks and some plants. They live for 15 to 20 years and spend most of their time on drifting packs of ice, eating and resting. The bears reach sexual maturity 3 to 5 years after birth. Each year pregnant polar bears dig a den in the snow of southern facing slopes, where they give birth. The females give birth to one or two cubs. Cubs are naked, blind and deaf when they are born
Whale There are 13 species of great whale and several species of smaller whales. Whales are large, intelligent, aquatic mammals. Whales have many features that we- other mammals have. Such as four-chambered heart,hair, they are warm- blooded. They are the only mammals, other than seacows , that live their entire life in the water, and the only mammals that have adapted to life in the open oceans. Whales are not fish, because they have lungs and they breath air with them.What is special about the whales is their size. They are enormous.
The panda uses this bone in same way humans use their thumbs, mainly for grasping food. Sense of Smell · Pandas leave scent marks in their territories. The scent marks serve as a major form of communication. Pandas can determine from the scent if another panda is in the area, including if the other panda is male or female, how recently they left their scent and in the case of female if they are in a reproductive period. · To mark their location, pandas will back up to a tree and rub their scent glands on the tree, then use their tail to spread the scent. Some pandas, particularly males will back up on the tree until they are virtually doing a handstand in order to place their scent higher on the tree. History · The Giant Panda was first made known to the West in 1869 by the French missionary Armand David, who received a skin from a hunter. · The first westerner known to
Characteristics Giant Eland are typically between 220-290 cm (7.3-9.6 ft) in length, stand approximately 150 to 175 cm (4.9 to 5.7 ft) at the shoulder, and weigh 440-900 kg (968- 1,980 lb). Despite its common name, it is of very similar size to the Common Eland. The smooth coat is reddish- brown to chestnut, usually darker in males than females, with several well-defined vertical white stripes on the torso. A crest of short black hair extends down the neck to the middle of the back, and is especially prominent on the shoulders. The slender legs are slightly lighter on their inner surfaces, with black and white markings just above the hooves. There are large black spots on the upper forelegs. The bridge of the nose is charcoal black, and there is a thin, indistinct tan-coloured chevron between the eyes. The lips are white, along with several dots along the jaw-line.

and the surrounding ocean. The total land mass is almost 8,000 sq. km. Highest peak is Wolf Volcano reaching 1707m. The present islands are all younger than 4 million years and were formed separately from other land masses as a result of volcanic eruptions. The Galapagos were discovered in 1535 by Fray Toms de Berlanga, the Bishop of Panama. He was sailing from Panama to Peru when he accidentally discovered the islands. Islands became a favorite hideout for Pirates and the favorite location for whale hunters. After whales were locally cleared the whalers went there for tortoises, an estimated 200 000 or more adults had been removed. The island of Floreana was populated with a group of convicts' in October 1832. Charls Darwin visited the island in 1835, he spent there 5 weeks. Nowadays five of the islands are populated with about 40 000 inhabitants. The name Island of Galapagos means island of tortoises. Every animal or plant had to cross about 1000 km of open ocean to arrive on Galapagos

extended throughout the whole coat, but being restricted to the skin of the extremities and to the eyes (for example in bay horses). This Norwegian Forest Cat was bred by Yve Hamilton Bruce from a silver mackerel tabby female (imported from Denmark) and a classic red tabby and white male. The result was 1 silver tabbies and 2 silver tabbies with white. At just over 3 months old, this silver and white tabby male developed a large patch of bright red hair on his back which continued to spread. Eventually the whole fur will become amber. The effect of amber during the colour-change stage depends on the original colour - solid black or blue, bicolour or tabby. The cat pictured is not a typical amber as it has the silver gene so the amber effect is overlaid on silver. A non-agouti amber Norwegian forest Cat resembles a silver tabby, but has a distinctive black nose and black paw-pads instead of the pink/reddish nose with black outlining found on
