Types of Reptiles: Names, Biological Traits, Key Characteristics and Adaptation Techniques

From lizards to snakes there are around 12,162 species of different types of reptiles in the world. Each of these crawling, slithering and walking fascinating creatures have different characteristics and live in different habitats ranging from terrestrial to aquatic environments.

What are Reptiles

Reptiles are cold blooded vertebrate animals that have scaly skin. It is one of the largest animal groups on earth with around twelve thousand unique species present in different parts of the world. Some of the common characteristics of all reptiles include their short limbs, scaly skin and ectothermic bodies that need heat for metabolism and energy. They are oviparous which means they reproduce by laying eggs.

Types of Reptiles 

The word retile is derived from the Latin word ‘reptar’ which means to crawl or slither. Based on unique characteristics the reptiles can be categorized into following four primary categories:

  • Crocodilia: This species of reptiles include semi-aquatic predatory reptiles such as crocodiles, alligators and caimans that are characterised by their thick scaly skin and elongated snouts. 
  • Sphenodontia: This species of reptiles arose in the mesozoic era and includes only one living genus called tuatara. They belong to an ancient, distinct lineage that is characterised by their unique skulls and a well-developed third eye. 
  • Squamata: This diverse group of reptiles includes snakes and lizards. There are around 9,200 species of squamata reptiles that are characterised by flexible jaws, movable eyelids and overlapping scales. 
  • Testudines: This shelled group of reptiles includes some fascinating creatures such as turtles, tortoises and terrapins. All the reptiles belonging to this species are characterised by their bony and cartilaginous shell that acts as their protective shield. 

Names of Common Reptiles

Here are some of the names of commonly found reptiles along with their unique features:

  • Snake: These crawling reptiles do not have limbs or legs and are found in different land and water habitats with more than 3,000 different species.
  • Crocodile: These semi-aquatic predatory reptiles have a v-shaped snout and live in water bodies such as rivers, lakes and oceans.
  • Turtle: With a protective shell covering, turtles are among the longest living reptiles on earth. These aquatic reptiles lay their eggs on dry land.
  • Lizards: With short limbs and long tails, these crawling reptiles are mostly carnivores and live in different habitats. 
  • Alligators: These are semi-aquatic reptiles that look similar to crocodiles but have many different characteristics like a U-shaped snout.
  • Iguanas: It is a large tree-dwelling lizard that is herbivorous and is known for its sharp claws and whip-like tail.

Unique Adaptation Techniques of Different Reptiles

Reptiles are amazingly adaptive species that can be found in every continent of the world except Antarctica. They exhibit many physical and behavioural adaptive traits such as molting, hibernation or estivation that help them survive in different environments. From camouflaging chameleons to flying dracos, reptiles are masters in adaptation and thriving in different kinds of habitats.
