As animals are heterotrophs, it means they feed on living organism directly or indirectly. Again these are sub divided into herbivores, carnivores, omnivores and parasites. Generally all animals are predators. It means they hunt for food on other living organisms. In general extinction of some animals had taken place since some year due to variations in the earth.
Animals are generally considered to have evolved from a flagellated eukaryote. Animals which are living close to hydrothermal vents and cold seeps on ocean floor will not depend on energy of sunlight. Animals are divided into two broad groups: vertebrates and invertebrates. Vertebrates are animals which have back bone. Invertebrates are animals which do not have backbone. There are different types of animals in the world. Let's see how many we can post with a short description of different types of animals in the world with their photos.
I will start with Squirrels "the cute little highly unstable creatures". The most surprising thing about them was the photograph was allowed to come very close to them. I think we all "Love Watching Them!!!
This is intended to be an ongoing topic so feel free to add as many animals as you would like! Like the squirrels most animals have several different members in the group. Some will surprise us all!
