From Seals to Whales: 7 animals that produce thickest milk on earth

Milk serves as one of the most crucial survival tools for infants provided by nature. However, not all milks are the same. For instance, while human milk contains about 4-5 percent fat and cow's milk comprises 3-4 percent fat, other mammals can produce such fat-rich milk that it would be comparable to a cream rather than a regular milk. According to scientists, mammals residing in tough climatic zones require very fat-rich milk in order to allow their offspring to put on weight quickly, keep them warm, and provide them with energy reserves. These are just some of the most fat-rich types of milk produced by different mammals in the world.
