North American Amphibians: Introduction

(Scroll down to see the list)

North America is the world’s third-largest continent. It has polar, temperate and tropical regions, and a wide range of habitats, including temperate and tropical rainforests, grasslands, mountains, rivers and lakes.

Unsurprisingly, North America is home to a large number of amphibians. Species in all three amphibian orders are present on the continent, although there are only 3 caecilians (all of which are found in Mexico).

  • The three amphibian orders are: Anura (frogs and toads); Caudata (salamanders); and Gymnophiona (caecilians).

American Bullfrog

American bullfrog
During the winter months, the American bullfrog is able to hibernate at the bottom of a pond without having to come up to the surface to breathe.

  • Scientific name: Lithobates catesbeianus
  • Conservation status: Least Concern

The American bullfrog is the largest member of the ‘true frog’ family Ranidae found in the US. It is native to the eastern United States and Canada. The species has also been introduced into many other parts of the United States and as well as into Mexico.

The American bullfrog is olive-green in color. Males are smaller than females, and can be identified by their yellow throats.

The bullfrog gets its name from the loud, ‘bull-like’ calls made by the males during the breeding season.

  • Family: Scaphiopodidae

Members of the amphibian family Scaphiopodidae are known as the American spadefoot toads. They are divided between two genera: Scaphiopus, or North American spadefoots; and Spea, otherwise known as the western spadefoot toads.

American spadefoot toads get their name from the hard, spade-like projections on their feet. This adaptation allows them to dig backwards into soft earth. Some species spend as much as 10 months of the year underground.

  • Family: Amphiumidae

Amphiumas are aquatic salamanders in the family Amphiumidae. (Aquatic salamanders spend all of their lives in the water, whereas terrestrial salamanders leave the water after having metamorphosed.)

Amphiumas have elongated, eel-like bodies. Their legs are very small and are vestigial (i.e. they have no function, and are the remnants of the legs of ancestral species).

Amphiumas are also known as ‘Congo eels’ due to their long, slender bodies.

There are three species of amphiuma: the three, two and one-toed amphiuma. All are found in the United States.


The axolotl never undergoes metamorphosis and retains its gills even in adulthood.

  • Scientific name: Ambystoma mexicanum
  • Conservation status: Critically Endangered

The axolotl is an aquatic salamander found in Mexico. Due to habitat loss the species is now critically endangered in the wild. Unlike many amphibians, the axolotl does not undergo metamorphosis. It retains its gills and does not leave the water even as an adult.

Axolotls have the ability to regenerate lost limbs and other body parts.

The cave salamander is frequently found in caves, but is also present in forest habitats. The tail is prehensile (able to grip) and is used when climbing.

Colorado River Toad

Colorado Toad American Amphibian

  • Scientific name: Incilius alvarius
  • Conservation status: Least Concern

The Colorado River toad is also known as the Sonoran Desert toad. It is found in desert habitats in the southeastern United States and in Mexico. It is the largest member of the ‘true toad’ family (Bufonidae) native to the United States.

(The cane toad – an invasive species introduced from South America – is the only toad found in the United States larger than the Colorado River Toad.)

The Colorado River toad grows to around 19 cm (7.5 in.) in length. Its skin is warty and olive-green / brown-green in color. At the back of its head are two large poison glands. Eating a Colorado River toad can be fatal for a pet dog.

Common Mudpuppy
