Amazing Facts

The animal kingdom is full of wonders that encouraged many researchers to spend their life observing different animal lives, habitats, and relations. Scientists divide animals into two primary groups: vertebrates and invertebrates, where the primary distinction between them is the backbones. According to this fact, Mammals, birds, and reptiles all fall into the category of vertebrates.  

Let's go and check out some amazing facts! 


Mammals are vertebrates classified into more than 5400 distinct species; it is categorized into four different types, ones that live on the ground, ones that can fly, ones that live underneath the earth's surface, and mammals that live underwater. Curious to know more?  

  • Do you know that the blue whale, which may grow 110 feet long, is the largest animal alive today, and it's even said to be larger than many known dinosaurs? 

  • The most miniature Bat is the bumblebee Bat, a rare mammal barely 3 cm long and weighs no more than 2 grams; imagine the size of this Bat if it was in your hand.   

  • Do you think that Squirrels are cute? Add to the list clever as Squirrels have been spotted disguising their scents from Snakes by biting on the snakeskin and rubbing it all over their hair; cruel, you might think, but lifesaving.  

  • Heat is no problem to Meerkats as they have sparse hair and black skin on their belly, which aids with regulating body temperature no need for AC!   


Reptiles, including Lizards, Snakes, Crocodiles, and Turtles, are among the most spread animals worldwide; hence you can find humans with excellent knowledge about them. What makes Reptiles different is that their bodies are covered with scales; some species lay eggs and are called (Oviparous), and some give birth (Ovoviviparous). Here are some facts  


  • If you wonder why reptiles are wide speeded worldwide, think about 11690 Reptile species, a big number? Yes, but interestingly Snakes account for approximately 3000 species of all Reptiles.  

  • As different as a Snake scale looks, it's formed of keratin, the same material that makes up human hair and nails.  

  • Slow, steady, and always wins; Turtles are anapsid reptiles, meaning their skulls have no holes.  

  • The Crocodile's hard skin does not have perspiration receptors, so Crocodiles expel excess heat via their mouth to keep cool! 

  • Reptiles require oxygen to survive. They are unable to survive underwater.  

  • Except for a few Reptile species, most reptiles are hatched from eggs.  

  • Most Reptiles, except for Snakes and some Lizards, have four legs! 


When most people think of Birds, they think of flying; most birds can fly, but some can't. Birds are a type of warm-blooded animal distinguished by feathers, beaked mouths, tough eggs, a rapid metabolism, a four-chambered heart, and light bones. There are over 9000 species of bird that have been identified by scientists. Following are some of the interesting facts that you need to know about birds:  

  • The eyesight of a falcon is thought to be at least 2.5 times better than that of a typical human. They have a bilateral vision, which allows them to see their prey from a distance.  

  • Owls are a type of nocturnal bird that do not move their eyes since their pupils are conical in form, and they can move their heads to 270°.  

  • Rather than lips, all birds have a beak.  

  • Birds that can fly have relatively hollow bones to make them incredibly light, and large breasts to move the wings and fly.  

  • Migratory birds move with the seasons, looking for places with more suitable conditions.
