Class: Amphibia
Order: Anura
Family: Bufonidae
Genus: Bufo
Species: B. americanus

Identifying characteristics:
  • warts on their back are generally more than one wart per black spot
  • there are orange spots around the toes
  • there can be lots of color variation, so is not usually a great way to identify, but generally a shade of brown.
  • Males have black throats, and females have white throats
Adaptations:
  • shed their external skin every couple of weeks as juveniles, adults lose their skin around four times a year.
  • Chose to be nocturnal to decrease chances of predation.
  • Hibernate under rocks, logs or dead leaves. They will actually dig out the dirt in regions of cold winter with their back legs.
  • Noticeable call that attracts females for breeding, but they also use body posture, touch and chemical to communicate.
  • Have a poisonous gland that deters some of their snake predators, but if that isn't effective, they will also urinate, and puff themselves up with air.
