2-Fin Whale
In the second position in the ranking, the fin whale gains of all when it comes to longevity. She is able to live a hundred years. Another curiosity about it is its power of communication. The low-frequency pulses that issues are so strong that other whale of the same species can pick them up to 850 kilometers away.
