Humpback Whales are mammals belonging to the baleen whale suborder and can be found in oceans and seas around the world
Humpbacks are well known for breaching, and their complex songs. The name humpback whale describes the motion it makes as it arches its back out of the water in preparation for a dive. Humpback Whales can be easily identified by their obvious humps and black upper parts. The head and lower jaw are covered with small, round bumps on the front of the head called knobs or tubercles, and are characteristic of the species.
The pectoral fins, which are up to one-third of a Humpback Whale body length, have rough edges are the largest flippers of any whale. They breathe air at the surface of the water through 2 blowholes located near the top of the head. Their blow is a double stream of spray that rises 3.1-4 m above the surface of the water and the flukes can measure up to 3.7 m wide. An adult usually ranges between 12-16 m long and weighs approximately 36 tonnes.
The female Humpback Whale typically breed every two or three years. The gestation period is eleven months. A Humpback Whale calf is about 4–- 4.5 metres long when born and weighs approximately 700 kg. Calves are nursed by their mothers for their first six months, then are sustained through a mixture of nursing and independent feeding for a further six months. Calves leave their mothers at the start of their second year, when they are typically 9 metres long. Both males and females reach sexual maturity around the age of five. A Humpback Whale can live for 45–- 50 years.
