Its pectoral fins are large up to 5m, unlike those of other cetaceans. They serve to steer and brake.
She breathes through two vents and plunges to a depth of 250m with freediving times of 15' to 45'. The man dives in apnea at 130m for a time around 4'.
The humpback whale has a very curious character and easily goes into contact. Each encounter is different : You will observe, for example, a calf learning to emancipate from his mother and to control his pectoral fins. He has to breathe more frequently than adults and makes shuttles between his mother and the surface. A little later, you will see two competing males courting a female, pushing and causing spectacular bubble curtains. In order to interact with the female and delimit their territory, they emit a melodious song.
This impression of rounding is due to his way of diving head first to the side. The humpback whale is a baleen whale. It is about 16 meters long in adulthood and weighs on average 25 tons. His life expectancy is 50 years old.
Its feeding areas are in the cold waters near the poles where it consumes huge quantities of krill that it stores. Then she migrates to the tropics to mate and foal, traveling up to 16,000 km round-trip a year on average. It is driven by the magnetic field at a speed of up to 25km/h.
You will be amazed by this fascinating giant of the seas that can perform spectacular jumps out of the water, fall on the back or hit the water with its fins.
Each individual has a different caudal fin, which allows them to be identified. This fin serves as a propeller.
Do you know that the song of the whale is considered to be the most complex of the animal kingdom ? She can last up to 30 minutes and be heard hundreds of miles away. Depending on the group, the vocalizations may differ, suggesting that there is a real dialect between the groups. Females and calves emit shorter sounds such as grunts or pulsed sounds. The song of sexual parade is different from that of fishing.
This strange and soothing melody has been chosen among other sound samples of our planet by the NASA engineers to transmit a message of peace embedded on the Voyager probe.
