Elephant

Elephants are large land mammals in two genera of the family Elephantidae: Elephas and Loxodonta. Three species of elephant are living today: the African bush elephant, the African forest elephant and the Asian elephant.

Elephants are the largest land animals now living. The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 120 kilograms (260 lb). They typically live for 50 to 70 years, but the oldest recorded elephant lived for 82 years.

Ostrich

The Ostrich, (Struthio camelus), is a large flightless bird native to Africa. Ostriches have a long neck and legs and the ability to run at maximum speeds about 97.5 kilometers per hour (60.6 mph), the top land speed of any bird. The Ostrich is the largest living species of bird and lays the largest egg of any living bird. 


The ostrich lays the biggest egg in the world, ostrich eggs are 4.5 x 7 inches (11 x 18 cm) across and weigh 1400 gram. One ostrich egg is equivalent in volume to two dozen chicken eggs.
