(1.25pts) For a long time the image most people had of a gorilla was a dangerous-looking animal with big, bared teeth. But researchers studying gorillas show a very different picture of mountain gorillas. The animals are peaceful, gentle, sociable, and mainly plant-eating creatures. Gorillas live in family groups. A typical group is led by the biggest and strongest grown-up male gorilla. He is called a silverback because the hair on a male's back turns from black to silvery grey as he grows up. A silverback's group usually includes one or two sub-adult males and a few females and their young. Mountain gorillas spend much of their time eating. Their food includes a variety of plants, along with a few kinds of insects and worms. At night the animals make a nest to sleep in. Many lightweight gorillas nest in trees. The heavier ones may nest in grasses on the ground. Babies sleep with their mothers at night. Life for mountain gorillas is not always peaceful. They are endangered and threatened by civil wars in the smaller parts of Africa. Hunters kill them for food. Their forests are cut down for farmland, fuel, and housing. But many scientists, forest rangers and other concerned people are working hard to protect mountain gorillas and their habitats.
