Why in News

A recent study conducted by Australian universities has found out that the Komodo dragon could become extinct in the next few decades due to climate change.

Key Points

  • Scientific Name: Varanus komodoensis.
  • Komodo dragons are the largest and heaviest lizards on Earth. They have long, flat heads with rounded snouts, scaly skin, bowed legs, and huge, muscular tails.
  • Komodo dragons can eat almost anything, including invertebrates, birds, and mammals like deer, pigs, and even large water buffalo.
  • They have venom glands loaded with toxins which have been shown to secrete anticoagulants.
    • An anticoagulant is a compound which prevents the victim's blood from clotting, causing it to bleed to death.
    • The venom lowers blood pressure, causes massive bleeding, and induces shock.
  • Habitat:
    • Komodo dragons have thrived in the harsh climate of Indonesia's Lesser Sunda Islands for millions of years. They prefer the islands’ tropical forests but can be found across the islands.
    • Komodo National Park, a UNESCO World Heritage site, is situated in the Island of Komodo (eastern Indonesia) and is the only habitat for this lizard species.

  • Threats:
    • Anthropogenic factors.
    • Small size of population, less prey and higher inbreeding factors.
    • Climate change is likely to cause a sharp decline in the availability of habitat, reducing their populations even further.
  • Conservation:
