13. Immune System Adaptations
Sloths’ slow metabolism and specialised way of life have shaped particular qualities in their immune system. Although they move more slowly than other mammals, their immunological responses have evolved to be really highly efficient. This system has evolved specific strategies to handle the several parasites and bacteria that call their fur environment home. Their blood consists of modified white blood cells that, in low energy consumption, can efficiently fight infections. Although their modest metabolic rate, the evolution of antibody synthesis has made them more focused and efficient, thereby enabling good immune protection. This modified immune system shows how evolution may change intricate biological systems to fit certain environmental needs.
