For the longest time, it was thought that the frogs and the toads were two different kinds of animals. All toad-like species were placed in the family of the toads, Bufonidae. This split was based on the following caracteristics:
*toads have a warty skin, frogs have a smooth skin
*toads have shorter hind legs, frogs longer hindlegs
*toads cannot jump or swim as well as frogs
Since the 80's we know that these caracteristics are spread through all the frogs and toads. There are frogs with a warty skin that cannot jump so well because of their shorter hind legs (Alytes). There are also toads with smooth skin and longer hindlegs (Atelopus). We call this diversity of caracteristics convergent evolution.
Sometimes this change of vison is confusing, because species that were formerly assigned tot the toad-family, are know considered to be a frog, but the name 'toad' is still used in their common name! An example is the famous firebelly toad. This animal is, dispite its name, not a toad, but is considered a toad-like frog.
No the small bumps look like warts and are also called warts but are in fact slime- and poison glands. The urban legend you can get warts if you handle a toad is not true; warts on humans are caused by a virus and not via toads. Although most think warts are caused by toads, this is nothing but a myth. But if you handle one make sure to wash your hands after you have, because they can carry minor infections.
Well we have two things, newly hatched frogs and toads are tadpoles. New frogs and toads who have recently become frogs and toads from tadpoles are called froglets and toadlets,
They are vertebrates.
toads
No. Toads can not give birth to frogs. Toads and Frogs are different species.
Toads have a developed Bidder's organ, frogs have a degenerated organ wich will not be functional.
A frog is a amphibian. toads are amphibians too, but most toads that are called toads are really frogs. only 250 of the species bufo are really toads.
Both toads and frogs have bumpy skin, but toads typically have drier and rougher skin compared to frogs. Frogs generally have smooth and moist skin that helps them absorb water and oxygen.
Frogs are often confused with toads.
