Sneaky's Daily Did You Know....? - Remarkable Reptiles and Amazing Amphibians

The Acolotl Salamander from Mexico is the Peter Pan of the amphibian world - it never grows up. As long as it remains in water (which can be for its entire life), it retains its larval tadpole-like shape. It can even breed in this form.
