giraffes are one of the world"s tallest mammals. they are well known for their long necks， long legs， and spotted patterns.
giraffes have small "horns" or knobs on top of their heads that grow to be about five inches long.
these knobs are used to protect the head in fights. male giraffes are larger than females.
males weigh between 2，400 and 3，000 pounds and stand up to 19 feet tall! female giraffes weigh between 1，600 and 2，600 pounds and grow to be 16 feet tall.giraffes live in the savannas of africa， where they roam freely among the tall trees， arid land， dense forests and open plains.their long necks help giraffes eat leaves from tall trees， typically acacia trees. if they need to， giraffes can go for several days without water.
instead of drinking， giraffes stay hydrated by the moisture from leaves.
