Where to see them

Did you know…

  • It is the second heaviest lizard in the world after the Komodo dragon.

    From Common Water Monitor

  • It is very tolerant of people, and common in canals and city parks.

    From Common Water Monitor

  • Its skin is widely traded for the fashion industry.

    From Common Water Monitor

  • Its teeth are blunt and flattened rather than sharp, adapted to crushing the shells of beetles, snails and millipedes instead of tearing flesh, a clear case of specialisation within a group of generalist predators.

    From Savanna Monitor

  • It is one of the most heavily exported reptiles on the planet: hundreds of thousands of animals leave Ghana, Togo and Benin each year for the pet trade, most of them caught in the wild.

    From Savanna Monitor

  • It aestivates through the dry season: it buries itself in a burrow and lowers its metabolism until the rains return, going months without eating.

    From Savanna Monitor

  • It often lays its eggs inside occupied termite mounds, which the termites then repair, providing a natural incubator at steady temperature and humidity.

    From Nile Monitor

  • It eats crabs and insects (50-70% of its diet), supplemented with small vertebrates, eggs and carrion.
