The video explains the phenomenon of exploding whales, focusing on the biological processes that occur after death. It discusses how gas buildup, primarily methane, results from bacterial overpopulation in large organisms like whales and elephants. The video also covers the chemical reactions that produce foul-smelling compounds and the conditions leading to explosive pressure release. The phenomenon is unique to large organisms due to their significant biomass, which allows for substantial gas production.
