Reptiles

Reptiles are members of the Class: Reptilia, under the Phylum: Chordata, of the Kingdom: Animalia. Modern reptiles are widely distributed on all continents except Antarctica. The class: Reptilia are also distributed in sub-groups:

  • Testudines (turtles, tortoises and turtles),
  • Sphenodontia (tuataras from New Zealand),
  • Squamata (lizards, snakes and lizards), and
  • Crocodilia (crocodiles, gulls, caimans and alligators).

All reptiles have our members or are descendants of four-member ancestors, e.g., snakes. Reptiles live mainly on the ground, while some may also reside in trees. Most reproduce by laying eggs, however some may retain eggs until hatching and others give birth to live youngsters, such as mammals.

All reptiles are cold-blooded, which means they have trouble keeping their body temperature constant and are often based on external sources of heat, such as sunbathing. The skin of the reptiles is quite thin and is protected by scales or shields. These sometimes have a bony base that forms a shell.

Most modern reptiles are carnivores and survive mainly by eating insects, small and medium mammals and other reptiles. Some have evolved to survive totally or partially of plants, including, several types of agamas and iguanas. Currently, turtles make up the only group of predominantly herbivorous reptiles.

Reptiles vary greatly in size and weight. They range from a tiny gecko, which can grow up to 17 mm (0.7 in) to the saltwater crocodile, which can grow up to 6 m (19.7 ft) in length and weighs more than 2,000 pounds (2,200 lbs).

Lizards

On the other hand, the lizards are part of the Order: Squamata, of the class: Reptilia. Therefore, lizards are a type of reptile. They actually make up the largest order in the reptile class. There are approximately 5,600 different species of lizards. Like all reptiles, lizards are available on all continents except Antarctica.

Most lizards, like most reptiles, are four-membered, cold-blooded and carnivorous. In addition to the feet, they also have outer ears, a feature not shared by all reptiles. Lizards also have a unique feature, called autonomy that allows them to separate their tails to escape predators. Vision, including color vision, is particularly well developed in most lizards. This is because many lizards communicate with body language or bright colors in their bodies.

Finally, lizards can range from a few centimeters like chameleons and geckos, to almost 3 m (9.8 feet) in the case of the Komodo dragon. The Komodo dragon is the largest living varanid lizard to date discovered. Apart from the Komodo dragon, some of the most commonly known lizards are: gecko, chameleon, iguanas, horned lizards … There are also lizards without legs, which look like snakes. They share a common ancestry with lizards.
