The eastern spadefoot is a plump toad with a large head with a flat topped skull, large, protruding eyes and vertical slit-like pupils. It can grow to a length of about 9 centimetres (3.5 in). The skin is smooth with a scattering of small warts. The male has a large gland at the back of his fore legs which becomes enlarged in the breeding season.
This was one of the first amphibians to be listed under the Endangered Species Act in 1970. Will what the Fort Worth Zoo is doing help?
The common toad, European toad, or in Anglophone parts of Europe, simply the toad (Bufo bufo, from Latin bufo "toad"), is a toad found throughout most of Europe (with the exception of Ireland, Iceland, parts of Scandinavia, and some Mediterranean islands), in the western part of North Asia, and in a small portion of Northwest Africa.
The juvenile toad looks similar to the adult, but has more prominent ventral spotting and the undersides of its feet are yellow. The male red-spotted toad has a dusky throat and develops nuptial pads during the breeding season. [4] It may hybridize with the western toad (Anaxyrus boreas) in some locations, possibly with other toad species too. [3]
The toad is commonly found in lowland wet and moist forest zones, and is less frequently found in per-mountain wet forest and lower mountain wet forest zones. Its natural habitats are subtropical or tropical moist lowland forests , rivers , freshwater marshes , rural gardens, urban areas , and heavily degraded former forest.
Before the stubfoot toad laid its 20 eggs, the zoo had three females and one male from the species, Hanna said. The zoo got the group about two or three years ago, he said, when they were froglets.
A year later, he dug up the blocks and found that most of the toads were dead and decayed. A few toads that had been in the porous limestone were still living, but the glass had developed cracks which Buckland believed may have admitted small insects. However, Buckland found them all dead after reburying them in the limestone for another year.
The western toad (Anaxyrus boreas) is a large toad species, between 5.6 and 13 cm (2.2 and 5.1 in) long, native to western North America. [ 1 ] [ 3 ] [ 4 ] A. boreas is frequently encountered during the wet season on roads, or near water at other times.
