Breviceps fuscus have a round body with short limbs and toes. Its feet are inward facing which allows the frog to burrow much more effectively. They grow to about 40–51 mm (1.6–2.0 in) in snout–vent length.This species can also live anywhere from 4 to 15 years in age. [7]
[33] [34] If rocks are lacking, hellbenders have been known to use holes in stream banks as habitat. [32] On average, their home range is estimated to be 198 square meters as of 2005. [35] The ideal habitat for a hellbender has a large amount of gravel, low pH, cool water temperatures, and low specific conductivity.
From the African tree frog to the tiger salamander, there are thousands of species of amphibians that can be found scattered all over the world. Amazing Amphibians: A 5-Day Unit Plan for Kids Skip ...
The largest living amphibian is the 1.8 m (5 ft 11 in) Chinese giant salamander (Andrias davidianus) [41] but this is a great deal smaller than the largest amphibian that ever existed—the extinct 9 m (30 ft) Prionosuchus, a crocodile-like temnospondyl dating to 270 million years ago from the middle Permian of Brazil.

It is estimated that at least thirty percent of amphibian species are currently at risk of going extinct, [10] though some estimates put this figure closer to forty percent. [11] The threats to amphibian populations are diverse, but predominantly anthropogenic, including over-exploitation, habitat loss, introduction of invasive species, and ...
It is semiaquatic and is often found in streams, near springs, in canals and drainage ditches, and under water troughs. [5] The Colorado River toad is known to breed in artificial water bodies (e.g., flood control impoundments, reservoirs) and as a result, the distributions and breeding habitats of these species may have been recently altered ...
The Texas toad feeds on insects such as beetles, ants and bugs. It digs a burrow in soft soil and can bury itself in mud. It sometimes conceals itself in a gopher burrow, under a log or in a deep crack in the mud to prevent desiccation, spending much of its time dormant in prolonged dry weather.
It is crucial for most amphibians to maintain a high level of genetic variation through large and more diverse environments. Education of local people to protect amphibians is crucial, along with legislation for local protection and limiting the use of toxic chemicals, including some fertilizers and pesticides in sensitive amphibian areas.
