The Canadian Museum of Nature's Mammal Collection contains ca. 85,000 study skins, pelts, mounts, and skeletons, representing approximately 600 species. The museum holds the most comprehensive collection of Canadian mammals, with extensive coverage of Arctic regions. Carnivores, ungulates, rodents, and marine mammals are well-represented. The museum also holds many cetacean tissue samples (both dry and fluid-preserved) that were collected in the North Atlantic during commercial whaling operations in the 1960s and early 1970s.
