The Komodo dragon (Varanus komodoensis) is definitively the largest living lizard in the world.

These formidable reptiles are native to a few Indonesian islands and are renowned for their impressive size and predatory prowess. They are a true marvel of the reptile kingdom, embodying strength and adaptability.

Key Characteristics of the Komodo Dragon

Komodo dragons exhibit a range of characteristics that make them unique among lizards. Their size is particularly notable, setting them apart from all other species.

  • Scientific Name: Varanus komodoensis
  • Habitat: Primarily found on the Indonesian islands of Komodo, Rinca, Flores, Gili Motang, and Gili Dasami.
  • Diet: As apex predators, their diet includes a wide variety of prey, from small rodents to large deer, wild boar, and even water buffalo. They are also known to scavenge.
  • Conservation Status: Currently listed as Endangered by the IUCN Red List, facing threats from habitat loss and climate change.

Size and Weight

Komodo dragons display significant sexual dimorphism, with males typically growing larger and heavier than females. Their robust build allows them to tackle large prey and dominate their ecosystem.
