Amphibians Intro

Amphibians have two distinct phases to their lives: one in the water and one on land. They are born with gills and are confined to their aquatic environments for the beginning of their lives, but they gain lungs and the ability to leave the water after they undergo metamorphosis to adulthood. Even as adults many amphibians, like frogs and salamanders, spend much of their lives in and around aquatic environments. See a comprehensive list of herpetological species that can be found on the Refuge.

  • American Green Tree Frog

    Green Tree Frog

    (Hyla cinerea) True to their name, American green tree frogs can come in many shades of green, from yellowish-olive to lime. Contrary to part of their name, green tree frogs actually prefer the wet environments of ponds and lakes, and have even been known to frequent backyard swimming pools.

  • Eastern Narrow-mouthed Toad

    Eastern Narrow Mouth Toad

    (Gastrophryne carolinensis) This amphibian species is actually a frog. Unlike most frogs, it is terrestrial, meaning it spends more time on land than in the water. The Eastern narrow-mouthed toad's preferred habitat is underground as they are accomplished diggers. A certain level of moisture is necessary for the survival of any amphibian so the ground surrounding swamps, ponds, and streams are where they are most likely to be found. Their breeding season is triggered by the spring rains, and large numbers of them will congregate in certain ponds for breeding.
