What is a reptile ?

Reptiles are air-breathing, cold-blooded vertebrates like lizards, snakes, turtles, alligators and crocodiles. They mostly hatch from eggs. Both birds and mammals evolved out of reptiles. Mammals, birds and so as reptiles are part of the group called Amniota, which have been the dominating land vertebrates for more than 340 million years ago, since the era of the Carboniferous.

315 million years ago, Hylonomous or the forest mouse was the first reptile that lived in what is now called ea6stern Canada. They are about eight to twelve inches in length and feeds on insect. During the Triassic period, approximately 230 million years ago, larger reptiles or the first dinosaurs evolved and dominated the ecosystem for 160 years. Howeever, they were wiped out 65 million years ago, during the Cretaceous-tertiary event of extinction.

During the age of reptile, various records were set, including the largest carnivorous reptile called the Spinosaurous that measures sixty feet and weighs around 9 tonnes. Amphicoelias Fragillimus, approximately 200 ft, was recorded as the longest animal ever existed, while the heaviest one, Bruhathkayosaurous weighed 220 tonnes.

A reptile’s metabolism depends on the temperature of its environment. Being cold-blooded, most lizards and snakes are sunning themselves on trees or rocks. The advantage of being a reptile is that they can go for weeks without food. Most of the reptiles are omnivores or eat anything that they can find, while others feeds on insects alone. Other reptiles, like crocodiles, are commonly carnivorous.

    Woah! I’m really digging the template/theme of this site. It’s simple, yet effective. A lot of times it’s hard to get that “perfect balance” between usability and appearance. I must say that you’ve done a great job with this. In addition, the blog loads extremely fast for me on Firefox. Outstanding Blog!
