The Page of Humpback Whales
The Humpback Whale is a baleen whale and one of the larger baleen whales. They have very unique body shapes with long fins and a knob head. They are found in oceans and seas all over the world. Because of hunting, the population of humpback whales fell by 90%.
Whales have a common ancestor who are the hippos. They evolved about 54 million years ago. Whales entered the water about 50 million years ago. Whales are warm blooded mammals that breathe air into their lungs and feed their young milk from mammary glands and have little hair.
The estimate of humpback whales is over 10,000- 15,000 humpback whales in the whole world. Humpback whales are an endangered specie that live in North Pacific Ocean, North Atlantic Ocean, and Southern Hemisphere.
The head of a humpack whale rounded and bold. The body is round and the top of the head and lower jaw has oval bumps. Adult males weigh up to 25-40 ft. Adult females measure up to 45-50 ft. Both adult male and females can weigh 25-40 tons.
The whales eat up to 1 and 1/2 tons of food a day. They eat krill,shrimip, plankton, and other small fish.
Females have kids every 2-3 years on average. Within 30 minutes newborn baby whales can swim!!! A newborn is 14 feet long and weighs an estimated 2.5 tons. They drink 100 pounds of milk each day.
They can stay in the water for a very long period of time without coming out. The only reason whales come to the surface is to breathe.
A humpback can swim up to 3-9 mph but goes up to 15-16.5 mph when in danger.
