The common raccoon (Procyon lotor) is a mid-size mammal distinguished by its black face mask and ringed tail. It is a member of the Procyonidae, a primarily tropical family of omnivores native to the Americas — and the only one of this family found in Canada. Raccoons are found in every province except Newfoundland and Labrador. A nocturnal species, it is highly adaptable and can survive in urban areas as well as wilderness habitats. Humans often consider raccoons pests due to their skill and persistence in raiding garbage bins, gardens and crops for food.

Rattlesnake is the common name for about 30 species of venomous, viperid snakes in the genera Crotalus and Sistrurus, found from southern Canada to South America. Three species of rattlesnake are found in Canada: the Western rattlesnake (Crotalus oreganous), the prairie rattlesnake (Crotalus viridus) and the Eastern massasauga rattlesnake (Sistrurus catenatus). Another species, the timber rattlesnake (Crotalus horridus) is extirpated, meaning the species no longer exists in the wild in Canada, but lives elsewhere.

Reptiles are a group of vertebrate animals that, like mammals, produce an amniote egg, with extra-embryonic sacs for waste, yolk, and protection, and often possessing a shell, particularly if released by the female before development of the embryo is completed. DNA analysis has allowed comparison of the genes in common for living organisms and new fossils have augmented our knowledge of the sequence of appearance of many features. Combined, these lines of research have produced changes from classical classification in which birds were regarded as most closely related to mammals primarily because they are both endothermic (able to maintain an internal body temperature). Now it is believed that each evolved this feature independently and that birds are derived from dinosaurs. Today's reptiles represent 2 main lines: Parareptilia or Chelonia (turtles) and Eureptilia or Diapsida, which contains the Lepidosauria (Tuatara, lizards and snakes) and Archosuria (crocodilians and birds).
