Interesting facts!

  • The word ‘milk’ in their name refers to the poisonous milky fluid these frogs excrete through their skin when threatened.
  • Amazon milk frogs have special toe-pads on their feet to help them climb plants. These toe-pads can hold up to 14 times a frog’s body weight!
  • Adult milk frogs are light grey with brown or black bands, while young frogs are more deeply coloured. As the frogs age, their skin becomes speckled and develops a bumpy texture.
  • Their blood is blue, which can give their skin a blue or green tint.
