Fun facts

  • It has a windscreen wiper of its own: a fold of skin behind the eyes that it pushes forward with its front legs to sweep off the ants that climb onto its face while it feeds beside a nest.
  • It eats almost exclusively ants, including the invasive fire ants of the south-eastern United States, to whose venom it shows some resistance.
  • Its breeding is explosive: it emerges after heavy summer rain, breeds in ephemeral pools and the tadpoles complete metamorphosis in barely three weeks.
