Western chorus frogs live in a variety of different habitats, but areas of more permanent water increase the risk of predation on eggs and/or tadpoles. To compensate for this, chorus frogs stick to mostly ephemeral freshwater areas, such as marshes, river swamps, meadows, grassy pools, and other open areas found in mountains and prairies.
In most cases this larval stage is a limbless free-living organism that has a tail and is referred to as a tadpole, although in a few cases (e.g., in the Breviceps and Probreviceps genera of frogs) direct development occurs in which the larval stage is confined within the egg.
This is the stage where frogs have all four limbs and are able to walk on land, but still have their tails. They are not quite juvenile frogs. Metamorphs are roughly 2.6 cm long, but they are nearly as agile as the adult and juvenile when they emerge from the ponds. They are often mistaken for the closely related leopard frog.
Frogs and toads are broadly classified into three suborders: Archaeobatrachia, which includes four families of primitive frogs; Mesobatrachia, which includes five families of more evolutionary intermediate frogs; and Neobatrachia, by far the largest group, which contains the remaining families of modern frogs, including most common species ...
Upland chorus frogs are secretive, freeze-tolerant, [3] nocturnal frogs, and are rarely seen (or heard) except immediately after rains. Their chorus will vary depending on the area they are found within, because they have significantly different pulse patterns in many different locations across their distribution. [ 2 ]
Wood frogs experience very little of the winter because they are frozen solid for the coldest eight months of the year. This is a high-risk strategy! If ice crystals form inside their body, they ...
The main predators of the Cascades frogs are the raccoon, mink, coyote, water bugs (Belostomatidae), garter snakes (Thamnophis sirtalis), and several bird species, such as the sharp shinned hawks, owls, Canada jays, and American robin. The long-toed salamander and adult R. cascadae frogs are predators to the eggs and tadpoles, as well.
