The spectacular Dead Whale Balloon is the longevity of a large baleen whale.

Spectacular dead whale balloon

When the life span of a large baleen whale comes to an end and its carcass is not found and torn up by predators in time, there is a high probability that the carcass will swell and become a "balloon" floating on the sea in the course of decay, and the abdominal cavity is filled with methane and other gases produced by fermentation. Of course, this state of affairs will not last forever. Eventually, the dead whale balloon will rot completely, leak into the sea, or be torn apart by diners such as the great white sharks who come in smelling bad odor.
