15 of the Strangest Animals in the World and Where to See Them

9: Echidna
The echidna inhabits some of the same territory as the Tasmanian devil, though its range extends onto mainland Australia as well. Echidnas are one of only two mammals that lay eggs. Though they resemble a porcupine, echidnas are actually a distant relative of the platypus, believed to have evolved 20 to 50 million years ago from an aquatic ancestor. Echidnas forage on the forest floor for ants and termites, using their long snouts to capture prey.
