Where are both pairs of limbs in mammals?

Both pairs of limbs are located on the body in different parts of it. They perform the function of movement, protection, grabbing objects and so on. Monkeys can move on their hind limbs, and the forelimbs – hands, are used as an aid for locomotion and for grabbing food. But you also need to remember that not all mammals have two pairs of limbs. Dolphins are mammals. Also, some other marine life are mammals, but instead of limbs, they have fins.
