Skins come from calves, foals, sheep, goats, and other small animals (young camels and seals). Hides are the skins of cattle, horses, donkeys, camels, deer, elk, walruses, and whales. Pigskin raw materials are the skins of domestic and wild swine. In addition to these most important types of leather raw materials, the skins of reptiles (crocodiles, lizards, and snakes) and fish (wolf-fish, cod, burbot, sheatfish, dog salmon, giant sturgeon, and shark) are also used.
