Amphibians appreciate the cool, wet shelter of caves and are sometimes seen along the tour route of the Oregon Caves. Such creatures are vertebrates (having a bony skeleton) that spend part of their lives in water and the remainder on land. Often as younglings they have an intimate link to water but as adults they may be found hiding under logs or resting near a hiking trail.

Amphibians are cold-blooded meaning their body temperature depends on the temperature of their environment. Two common orders are the newts and salamanders or the frog and toad groups.

On the Monument you may see or hear the Pacific Tree Frog. It is one of the smallest but loudest amphibians here. It can change color from green to brown in a few minutes for the protection of camouflage. Here is an adult and a teenager example.
