Although it has the ability to climb trees and other surfaces, rarely does it travel more than a couple feet above the ground. Tadpoles and Young Tadpoles aggregate for thermoregulation and to avoid predation.
A full change in the dorsal coloration of a color morph can take from weeks to months, but initial changes can occur in just a few hours. Color and Pattern Dorsal body coloring is variable: Provide them a few inches of water along with dry area beside.
The one below was found closer to the rocks and its skin was camouflaged accordingly. Tadpoles metamorphose in about 2 to 2. The slowest and least maneuverable swimmers are most likely to be eaten. This includes not only male Pacific Treefrogs, but other species of frogs, and even salamanders!
