During the final stages of transformation when the tadpoles have four limbs and a tail, they stop feeding for a short time while their mouths widen and their digestive systems adjust from herbivorous to carnivorous. Pacific tree frogs mature quickly, and usually mate the season after metamorphosis. They can live up to eight years in captivity.
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.
Frogs have no tail, except as larvae, and most have long hind legs, elongated ankle bones, webbed toes, no claws, large eyes, and a smooth or warty skin. They have short vertebral columns, with no more than 10 free vertebrae and fused tailbones (urostyle or coccyx). [ 47 ]
A few species deposit eggs on land or bypass the tadpole stage. Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on plant matter. Frog skin has a rich microbiome which is important to their health. Frogs are extremely efficient at converting what they eat into body mass.

The mating period of these frogs is during the fall and winter seasons. These frogs call usually during the morning and mid-afternoon hours. [15] Males of this species do not attract females with croaks, instead producing a sharp clicking sound by snapping the hyoid bone in their throats. [16] The clicking sound resembles metallic noises.
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 ...
They call during the rainy season. [4] Glass frogs have similarities to tree frogs. They look very close to the naked eye except glass frog's eyes point forward and are golden. During the day, these frogs camouflage themselves under leaves but above water. Male glass frogs are 19–28 mm long, while females measure from 23–32 mm long.
