But people called poachers hunt hippos for their teeth, ivory, and meat. Male hippos weigh about 3,300 to 4,000 pounds, whereas female hippos, (smaller) weigh only about 2,00 to 3,300 pounds. Baby hippos stay in their mothers stomach for 243 days before it is born into the wild or into the zoos. Hippos live in water and land. They live in Africa. Hippos mostly live for 40 to 50 years but the world's oldest hippo was 65 years old. Did you know that, a hippos jaws are so strong, they can bite through a CANOE with ONE BITE. Hippos are strong. They can fend off tigers. The tiger may be able to do some scratches, but that is about all it can do to the hippo.
