Most people don’t give urine a second thought, but the Leopard gecko is famed for its crystallized pee.
The Leopard gecko’s natural habitats are deserts and arid grasslands. The lizards have had to adapt to a dry environment. As such, they do not urinate, but instead pass powdery urate as a method of conserving water.
This allows the geckos to pass waste, such as uric acid, while enduring minimal water loss. With this method, they are able to stay hydrated in their crispy natural habitat.
