Zebra animals

The zebra is best known for the black and white striping pattern unique to each of the 3 species of zebra . Within a species, the pattern of the stripes is unique to each individual zebra, like with a human's fingerprint. There is some evidence that zebras recognize herdmates by their patterns. Zebras live together on the African plains in large herds often with or close to other herbivorous mammals such as antelope and wildebeest. Along with the wildebeest , the zebra takes part in the annual great migration following the rains across Africa. Herbivores do this in order to get the best grazing as the grass is at its best after the rain has passed over it. The female zebra usually gives birth to just one zebra foal after a 12 month gestation period. Female zebras have been known to give birth to zebra twins but it is a fairly fair occurrence.

Chimpanzee animals

The chimpanzee has a thickset body with long arms, short legs and no tail. Much of the body is covered with long black hair, but the face, ears, fingers and toes are bare. They have hands that can grip firmly, allowing them to pick up objects. The discovery that they used "tools" for certain purposes surprised the world.Chimps are mainly found in rain forests and wet savannas. While they spend equal time on land and in trees, they do most of their feeding and sleeping in trees.These large groups are made up of smaller, very flexible groups of just a few animals, perhaps all females, all males or a mixed group.

Hermit Crab animals


Hermit crabs are crustaceans that belong to the family Paguroidea. Unlike true crabs, hermit crabs have soft, vulnerable abdomen. In order to protect their soft bodies from predators, hermit crabs use abandoned shells of other marine animals, mostly snails. It is this habit of living in shells of other organisms that hermit crabs have derived their name from. A hermit crab carries its 'house' wherever it goes. Once it has outgrown its shell, it discards it and looks for a new shell. This behavior of the hermit crab gives rise to competition for shells among the members of this species. Over the years, these animals have gained popularity as pets. However, to ensure their good health in captivity, it is important to provide the ideal hermit crab habitat.

Giraff animals


Giraffes are the world's tallest mammals, thanks to their towering legs and long necks. A giraffe's legs alone are taller than many humans—about 6 feet (1.8 meters). These long legs allow giraffes to run as fast as 35 miles (56 kilometers) an hour over short distances and cruise comfortably at 10 miles (16 kilometers) an hour over longer distances.Typically, these fascinating animals roam the open grasslands in small groups of about half a dozen.
Bulls sometimes battle one another by butting their long necks and heads. Such contests aren't usually dangerous and end when one animal submits and walks away.

Kangaroo animals

The Kangaroo is the marsupial that is indigenous to Australia and and the Indonesian island of New Guinea. Although kangaroo are often seen congregating in groups, kangaroos are generally fairly solitary mammals but kangaroos are also known for being sociable animals when with other kangaroos. Kangaroos have a deep pouch on their front in which to carry their young. A baby kangaroo is called a joey.Kangaroos are most well known for their ability to jump a phenomenal distance. The kangaroo is the largest of the marsupials, a group an animals that includes koalas and the common possum. Marsupials are distinguished by the pouch that these animals have on their bellies, in which they carry their young. There are three main species of kangaroo in existence today and these are the red kangaroo, which is the largest and most well-known of all the kangaroo species. The Eastern grey kangaroo is known to be the heaviest species of kangaroo despite the fact that the red kangaroo is taller. The western grey kangaroo can be found in large numbers and can be anywhere in color from grey to brown. The kangaroo is the national animal and emblem of Australia.

Tortoise


The giant tortoise is probably the best known of all Galapagos animals and even gave the archipelago its name; 'Galapago' means tortoise in Spanish and may derive from the word for saddle, referring to the distinctive saddle-like shell of some of the tortoises. Galapagos giant tortoises can weigh up to 250 kg and live for more than 100 years. They are thought to belong to just one species, Geochelone elephant opus, with 14 different races or sub-species, three of which are believed to be extinct. It is likely that all the present races of giant tortoise evolved in Galapagos from a common ancestor that arrived from the mainland, floating on the ocean currents. Although this seems an incredible journey it is known that Galapagos tortoises can float easily in sea water. Only a single pregnant female or one male and one female needed to arrive in this way, and then survive, for Galapagos to be colonised.

Frog water animals

A Frog is a small, tail less animal that has bulging eyes. Almost all frogs have long back legs. The strong hind legs make the frog able to leap farther than the length of its body. Frogs live on every continent except Antarctica, but tropical regions have the greatest number of species. Frogs are classified as amphibians. Most amphibians, including most frogs, spend part of their life as a water animal and part as a land animal. Frogs are related to toads, but are different from them in a few ways. The giant frog of west-central Africa ranks as the largest frog. It measures nearly a foot (30 centimeters) long. The smallest species grow only 1/2 inch (1.3 centimeters) long. Frogs also differ in color. Most kinds are green or brown, but some have colorful markings. Although different species may vary in size or color, almost all frogs have the same basic body structure. They have large hind legs, short front legs, and a flat head and body with no neck. Adult frogs have no tail, though one North American species has a short, tail like structure. Most frogs have a sticky tongue attached to the front part of the mouth. They can rapidly flip out the tongue to capture prey. Frogs have such internal organs as a heart, liver, lungs, and kidneys. Some of the internal organs differ from those of higher animals. A frog's heart has three chambers instead of four. And although adult frogs breathe by means of lungs, they also breathe through their skin. The eggs of different species vary in size, color, and shape. A jelly like substance covers frog eggs, providing a protective coating.
