Wild Animal Information

Wild animals can be found everywhere in the ecosystems, which include; deserts, rainforests, plains and other areas, including a few urban sites. The term wildlife refers to animals that are untouched by human factors. Wild animal information will help us differentiate among animals and get a clear picture of the animals found exclusively in the wild. We will now look at a few wild animals.

  1. Mammals: Mammals are the most developed kind of animals in the animal kingdom. They are almost 200 million years old and had also lived in the age of dinosaurs. Mammals give birth to young ones, feed their young ones with mammary glands and have hair on them, compared to feathers and scales, which other animal class possess. The skeleton structure of mammals is very similar. They have a very striking similarity in reproduction, physiology and anatomy. Elephants, bear, blue whale, tiger, dogs, cats, wolf, lion and otter, are a few examples of mammals

  2. Birds: A large variety of these species move by flying. They are covered with feathers. Birds have a special substance called keratin in them, which help them do extraordinary skills. The first species of birds lived 140 million years ago. At present there are approximately 8600 varieties of birds around the world. Their skeleton is completely bony; suitable for flying. All birds lay eggs. Dove, stork, goose, crow, crane, eagle, sparrow, vulture, penguin, owl, vulture, are a few examples of birds.

  3. Reptiles: Reptiles are crawling beings, which can live in water as well as land. Reptiles are a lot different than amphibians. Even the egg structure is quite different. The egg of reptiles has got three protective membranes, with a shell. This helps them to survive without water. They lay eggs into water and have scales on their body. Snakes, lizard, tortoise, worm, chameleon, are a few examples of reptiles.

  4. Amphibians: Amphibians have been staying on this planet since 300 million years. There is a huge variety of their species, roughly around 3,000. Amphibians go through various stages from being water vertebrates to terrestrial animals. They can survive both on land and water. The larvae stage is when they breathe through gills while they are in water. Mature animals breathe through lungs as well as their skin. Their skeleton is mostly made of bones. They lay eggs in water. Agile Frog, American toad and tree frogs, are a few examples of amphibians.

  5. Fish: The exact number of species of fishes is yet to be discovered. We have around 22,000 species of them and scientists are still sorting them out. Fishes can survive only in water. Water covers about 71% of the earth's surface and thereby their numbers and very large and a bit impossible to get the facts right. They are so abundant that their variety exceeds the number to mammals, birds, reptiles and amphibians put together. Majority of fishes have a skeleton made of bones. They breathe with the help of gills and lay eggs for reproduction.

  6. Insects: Insects are the oldest of animals in the world. From the evolution point of view they are over 400 million years old. They can be found everywhere and often in huge numbers. They can be annoying at times to humans, but they help the ecosystem by removing dead animals, producing honey, etc. Some insects have wings whereas others don't. They lay eggs for reproduction.
