Habitat & Geographic Range
Canadian beaver
Typically found in grasslands, forests, and vegetated habitats.
Widely distributed across Europe (15 countries), North America (United States), and South America (Argentina, Chile).
Nile Crocodile
Typically found in diverse ecosystems where prey species are available.
Distributed across Egypt, Kenya, Madagascar, South Africa, and Tanzania.
Canadian beaver
The largest rodent in North America, Canadian beavers weigh up to 32 kg and are master ecosystem engineers inhabiting rivers, lakes, and wetlands across Canada and the northern United States. By felling trees and constructing dams up to hundreds of meters long, beavers create ponds that provide habitat for hundreds of species. Their lodges and canals transform entire watersheds. Once nearly hunted to extinction for their fur, beaver populations have recovered strongly.
Nile Crocodile
The Nile crocodile is one of the largest reptiles in the world and is found throughout sub-Saharan Africa.
