More than 5 billion animals are consumed each year as food
An estimated 17 million animals are use for Biomedical Research each year

Primates – Used to study the immune system. Have immunological similarities to humans and are susceptible to similar diseases. They often react to the same infectious agents as humans.
Mice – Aging. Mice age 30 times more rapidly than humans, with several body systems declining with age in the same manner as humans. Genetic composition and environmental conditions can be precisely and easily duplicated and controlled.
Squid – Nervous system. Movement of nutrients through nerve cells are studied. They have the largest axons and are used to study ALS in humans.
Armadillo – Reproduction & developmental biology. Can give birth up to three years after fertilization. Experience delayed implantation of the fertilized egg and give birth to identical quadruplets. Their low body temperature allows leprosy to grow. Used to study twins, menopause, infertility and leprosy in humans.
Ferrets – Immune system. Both ferrets and humans are affected by closely related bacteria. Used to study gastritis and stomach ulcers.
