Like other burrowing toads and frogs, a spadefoot toad
spends most of its life under the ground.
We did not observe or collect either species of spadefoot toad
until day 4 of succession.
Rubin returned to the site the same evening, along with another student, Phil Evers, and found a single spadefoot toad
, Scaphiopus holbrookii, in the flooded meadow.
In earlier research, Marie Simovich of the University of San Diego reported that the plains spadefoot toad
(Spea bombifrons) hybridized with the Mexican spadefoot (Spea multiplicata) when they happened to share shallow pools.

We examined the proximate basis of kin-mediated morphogenesis in spadefoot toad
This spadefoot toad
had better hurry up and snatch that cricket before it leaps away.
A desert-adapted amphibian closer to home is the spadefoot toad
, which spends most of the year buried like a stone, cool and moist.
Consider the spadefoot toad
that uses its namesake appendages to dig a home underground, lies there without breathing for months--even years in severe drought--absorbing oxygen through its skin, then emerges to feed and breed at the first music of raindrops hitting the soil.
Background: The European common spadefoot toad
(Pelobates fuscus) is listed in Annex IV of the EU Habitats Directive (i.
Some species, like the spadefoot toad
, even dig down through the soil.
Diet composition of the Mexican spadefoot toad
has been poorly studied, especially in the southern part of this species' geographic range.
A lawsuit forced revisions in its environmental impact report to address water supply and the Western spadefoot toad
, a state species of concern.
Three species collected in 1977-1978 (marbled salamander, Ambystoma opacum; green frog, Rana clamitans; and eastern spadefoot toad
, Scaphiopus holbrooki) were not represented in our summer subsets of data, but they were taken at other times of year.
In this study we examined, in a controlled laboratory setting, phenotypic plasticity in development time of the western spadefoot toad
Scaphiopus hammondii as influenced by changes in the water volume of the larval habitat.
