The Colorado River toad is sympatric with the spadefoot toad (Scaphiopus spp.), Great Plains toad (Anaxyrus cognatus), red-spotted toad (Anaxyrus punctatus), and Woodhouse's toad (Anaxyrus woodhousei). Like many other toads, they are active foragers and feed on invertebrates, lizards, small mammals, and amphibians.
Also, Fowler's toads are very fast hoppers (bursts of 5–10 fast hops) in comparison to Eastern toads lethargic, casual hopping and walking locomotion. In the eastern American toad these crests almost never touch the parotoid glands, which secrete bufotoxin, a poisonous substance meant to make the toad unpalatable to potential predators.
The yellow bellied toad also displays aposematism in its ventral body with varying shades of yellow displayed as a warning signal to predators of its poisonous skin. [6] Different individuals in the yellow-bellied toad species display variations of the darker dorsal and yellow ventral body, depending on their specific location.

They occur in the parotoid glands, skin, and poison of many toads (Bufonidae family) and other amphibians, and in some plants and mushrooms. [ 1 ] [ 2 ] [ 3 ] The exact composition varies greatly with the specific source of the toxin.
All true toads are toothless and generally warty in appearance. They have a pair of parotoid glands on the back of their heads. These glands contain an alkaloid poison which the toads excrete when stressed. The poison in the glands contains a number of toxins causing different effects. Bufotoxin is a general term. Different animals contain ...
