A. African Elephants

African elephants are the biggest land animals. They are enormous.

A male African elephant can grow up to four meters, and it weighs about six to seven tones.

They eat leaves and bushes.

They have got two tusks and a trunk. They drink 250 liters of water a day.

People hunt them for their tusks, so they are endangered. We should stop hunting them.

B. Pantropical Spotted Dolphin

Pantropical spotted dolphins are smart and friendly animals. They live in warm oceans.

They are big animals. The average size of a pantropical spotted dolphin is 2 .5 meters and about 120 kilograms.

They have a long, thin nose. They eat small fish. They are endangered because people try to hunt them,

and their habitats are getting hotter and dirtier. We should stop global warming and keep the environment clean to save this species.
