Toads and frogs are sometimes difficult to tell apart. Both groups of animals are known as anurans, or the tail-less amphibians.
To make things even more confusing, the term "frog" can correctly be used to describe both frogs and toads. And of course
the so-called "horned toad" isn't even an amphibian — it's really a reptile, and properly should be called a "horned lizard."
True toads are those amphibians belonging to the Genus Bufo. Toads have a number of characteristic features:
Little webbing on hind feet
Enlarged parotoid (poison) glands on the shoulders
Prominent tubercles (knoblike projections) on their hind feet for digging in the soil
In Alberta, there are three true toads:
Great Plains toad
Western (Boreal) toad
In addition to Alberta's three true toad species, there is one member of the Spadefoot family, the plains spadefoot.
Spadefoots lack the enlarged parotoid gland and they are less warty than true toads.
