The Fin Whale or finback whale is a baleen whale and the second largest creature on Earth; second only to the Blue Whale.
This remarkable creature is unique in a number of ways. For one thing they produce the lowest frequency vocalization of any whale. They produce sounds as loud as 188 decibels but the frequency is so low that humans can’t hear it.

The Sei Whale is another baleen whale and it’s the fourth largest of them after the Blue Whale, the Fin Whale, and the Humpback Whale.
