THE FROG THAT NEVER NEEDS AN X-RAY
In the trees of South and Central American jungles, you will find glass frogs of 2-8 cm with transparent skin.
Glass frogs are famous for their thin and partly transparent skin, particularly that of the belly. The skin is believed to provide camouflage, as the frog is hard to see for predators.
Females lay 20-30 eggs which, like the internal organs, can be seen clearly through the skin. Males protect the eggs after their laying, keeping them clear of parasites.
The frog’s organs are covered by a layer of pigment cells (iridophores), which can reflect and protect them against sunlight and heat. The frogs can grow 10+ years old.
