Interesting Topics / Classification of Animals


classification of Animals
Animals classification It is based on where they live(land, water), What They eat, Base on their habitats, body complexity, feeding habits, reproduction, etc.
Animals General Classification based on Based on backbone (Vertebrates, Invertebrates), Nutrition(Herbivores, Carnivores and Omnivores), Place They Live(Terrestrial Animals, Aquatic Animals, Aerial Animals, Arboreal Animals, Amphibians, Parasites), Decomposers.
Species on earth Approximately 1.2 million species
Animals Characteristics Huge Range
Example Birds(Vertebrates, warm Blooded, 2 legs, Lay eggs, some can fly, have feathers,Breathe with lungs, most live in land and water)Examples : Parrot, duck, peacock e.t.c

Reptiles(Vertebrates, Cold Blooded, Lay eggs, skin is dry,Breathe with lungs, most live in land and water)Examples: Snake, lizard , tortoise, lizard, crocodile e.t.c

Fish(Vertebrates, Cold Blooded, Dont have legs, Lay eggs, Breathe with gills, live in water)Example: Swedish, McFish, Puff Daddy, Floater e.t.c

Vertebrates Examples birds, mammals, fishes, lampreys, amphibians, and reptiles. E.T.C




Classification of Animals primarily based on Nutrition
Classification of Animals primarily based on Nutrition are of 3 types.They were
1. Herbivores / Heterotrophs.
2. Carnivores.
3. Omnivores.

Classification Based on Nutrition Animals whose Primary Food Source
Herbivores Definition Animals whose primary food source is plant based are called as Herbivores and they cant prepare the food by their own.
Carnivores Animals whose primary food source is meat / flesh of other animals are called as Carnivores and they cant prepare the food by their own.

Aerial Animals
Aerial Animals Definition The animals which can fly in the air for a numerous time called as Aerial animals.
Aerial Animals Examples Parrot, Butterflies, Wasps, And Fruit Flies, Kingfisher, Pigeon, Albatross E.T.C
Aerial Animals Features capability to fly in the air, have (wings, limbs , feathers).
