Humpback whale
Swimming, Snorkeling and Diving to See and Observe the Humpback whale
The humpback whale is recognizable by its completely black top and its almost white belly. It has a caudal fin that can reach up to one-third of the body's size, much larger than most cetaceans.
Adults can reach a length of 17 m and a weight of 23 tons. Humpback whales can dive to a depth of 200 m. It can remain at this depth for 10 to 40 minutes. It can live for 40 years. It can swim at speeds of 8km/h. Its skin is often infested with seashells. Heavy metals have been found in their tissue. Its predators are the man and killer whales as well as sharks big enough to attack the calves. Migrations do not occur in the same period in both hemispheres, so the whales from the north and from the south never meet, which explains the morphological differences.
It only sings during the mating period, it emits low tones that vary in frequency and amplitude, and this for hours or even days! It is a great moment of emotion to have the chance to listen to this song of seduction.

Food
Humpback whales have baleens instead of teeth. Baleens look like giant brushes lodged in their jaw. They drain the water and collect the zooplankton. The humpback whale feeds on herring, capelins, mackerels and planktonic crustaceans called krill. It follows the schools of krill in cold waters. It migrates northward in the summer. In winter, it swims southwards to give birth in warm waters favorable to the growth of the calves. They team up and create a bubble net by blowing through their blowhole on the top of their heads. They open their mouth vertically and swim to the surface to catch their prey.
Breeding
At the age of four, it reaches a length of twelve meters and sexual maturity. Mating takes place in tropical warm waters of both hemispheres. The males compete to win the favors of the females, which gives way to violent fights, amazing acrobatics, and beautiful songs. Mating and parturition take place between December and April in the northern hemisphere, and between June and September in the southern hemisphere. The gestation period lasts eleven months. The calf is four meters long at birth and weighs a ton and a half. At the end of the lactation period, it reaches a length of 9 m. Females give birth to only one calf every two years.
