Since the planet exists, what is the largest known animal ?

It is an extraordinary marine mammal that measures between 25 and 30 m. The blue whale still exists today despite the pollution of our oceans.

Join us and meet the blue whale, it plunges to a depth of 200m with times around 15 'apnea.

The man dives in apnea at -129m for a dive time around 4'.

The life expectancy of the blue whale is 80 years old. It moves between 5 and 50km/h.

The blue whale usually lives alone. It does not form large structured groups. It feeds mainly krill substantially 3.6T / day.

The sounds emitted by the blue whale oscillate between 15 Hz to 25 Hz. The man perceives the sounds between 20 and 20 000Hz.

Communications between blue whales in Sri Lanka were recorded as four-note repetitive songs lasting approximately two minutes each, similar to humpback whales.

The songs between the blue whales would serve to maintain an inter-individual distance, to identify themselves, to transmit information on the localization of food points (krill) and also to give the alert in case of danger. This dialogue would also serve to organize the social life between males and females.


Because of its size, power and speed, the blue whale does not really have a natural predator.

Blue whales are experiencing increasing mortality from vessel collisions or fishing net traps.

Increasing noise in the oceans covers sounds made by whales. Communication being made more and more difficult, this would explain the change in the frequency of their sound since a few decades.
