What is the scientific name and taxonomy of lizards

Lizards are reptiles that fall under the order Squamata and class Reptilia. There are over 6,000 species of lizards that can be found in every continent except Antarctica. Lizards come in all shapes and sizes, and some are even legless. The smallest known species of lizard is the Sphaerodactylus ariasae, or the Jaragua lizard, which was discovered on an island off the coast of Dominican Republic. The measure of the adult lizards ranges between 0.63 to 0.71 inches in length.

On the other end of the spectrum is the Komodo Dragon (Varanus komodoensis), the largest living lizard in the world. The largest verified specimen reached a total body length of 10.3 feet and weighed over 160 kgs. Varanus komodoensis is found on the Indonesian Islands of Flores, Rinca, Gili Motang and Komodo. This lizard is the apex predator of its environment due to its sheer size. Moreover, the saliva of the komodo dragon is supposedly venomous, secreting a toxic cocktail of proteins as well as anticoagulants.

Another group of lizards that superficially resembles snakes are members of the family Pygopodidae. Hence, these animals are sometimes called legless lizards. Pygopodidae are different from snakes because they possess a notched tongue rather than a forked tongue. Furthermore, Pygopodids have an outer ear opening also as eyelids.

1. What is the scientific name of lizards?

The scientific name commonly used for lizards is Lacertilia, though they are taxonomically grouped under the suborder Lacertilia (Sauria) within the order Squamata.

  • Phylum: Chordata
  • Class: Reptilia
  • Order: Squamata
  • Suborder: Lacertilia (Sauria)
The term refers to a large and diverse group of reptiles commonly known as lizards.

2. Is Lacertilia the scientific name of all lizards?

Yes, Lacertilia (also called Sauria) is the scientific suborder that includes all true lizards. It is not a single species name but a higher taxonomic grouping. This suborder includes thousands of species such as geckos, iguanas, chameleons, and monitor lizards, all classified under the order Squamata.

3. What is the scientific name of the common house lizard?

The scientific name of the common house lizard is Hemidactylus frenatus. It belongs to the family Gekkonidae.

  • Common name: Asian house gecko
  • Order: Squamata
  • Suborder: Lacertilia
This species is widely found in tropical and subtropical regions.

4. What is the scientific name of the garden lizard?

The scientific name of the garden lizard is Calotes versicolor. It belongs to the family Agamidae.

  • Common name: Oriental garden lizard
  • Order: Squamata
  • Class: Reptilia
It is commonly found in gardens and forests across South and Southeast Asia.

5. What is the difference between Lacertilia and Squamata?

The main difference is that Squamata is the order, while Lacertilia is a suborder within it that includes lizards.

  • Squamata: Includes lizards, snakes, and amphisbaenians.
  • Lacertilia (Sauria): Includes only lizards.
Therefore, all lizards belong to Squamata, but not all squamates are lizards.

6. What are some examples of lizards with their scientific names?

Some common lizards and their scientific names include well-known species from different families.

  • House gecko – Hemidactylus frenatus
  • Garden lizard – Calotes versicolor
  • Komodo dragon – Varanus komodoensis
  • Green iguana – Iguana iguana
  • Chameleon – Chamaeleo chamaeleon
All belong to the suborder Lacertilia under the order Squamata.

Lizards are classified under Squamata because they possess scaled skin and movable quadrate bones in the skull. Key characteristics of squamates include:

These features distinguish them from other reptiles like turtles and crocodiles.

Lizards are specifically squamate reptiles characterized by scales and usually movable eyelids and external ear openings.

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Reptilia
