When dissecting a frog, fat bodies are easy to identify. The fat bodies in frogs are yellowish to orange in color. They have a finger-like or spaghetti-like shape. The fat bodies are needed for hibernating, metamorphosis and for mating. These are areas in the body containing stored energy. They are located near the genitals inside of Amphibians. They are located near the testes in males and near the ovaries in females. Sometimes, they can be quite large and take up much space in the body cavity. Adipose tissue, or fat is necessary for survival, as it is an energy reserve.
