Thanks to countless curious individuals who tried poking stranded whales, viral videos of exploding whales are all over the internet. The dead carcasses of spem whales will decompose (very quickly if it is warm and there is a lot of sun) and After that, they need to dispose of the whale, but it is easier said than done. Many whales die when beaching themselves because their inability to return to the water means they either become dehydrated or they drown when high tide covers their blowhole, but they are unable to move. Cetaceans generally live long lives. Toothed whales do not have molars for chewing their food, they swallow it whole or in large chunks. Eventually, without warning – kaboom. Sometimes, the gas cannot escape through the whale’s thick blubber and tough skin. There have been several cases of whale carcasses bursting due to a buildup of gas in the decomposition process. The cause of the phenomenon was initially unknown, since it unexpectedly occurred in the spinal area … They gather much more food from the ocean than they ever could from rivers and estuaries. The Northern Bottlenose Whale – December 2020. Yet, it is not the end, as deep-sea organisms literally go to the bone when it comes to eating a whale carcass. They extract fats and oils from the skeleton and break down the whale’s bones. In fact, blubber-rich species such as right whales and bowheads, were easy whaling-targets because their huge amount of blubber made them float longer. If a whale dies at sea, scavengers such as sharks might relieve the pressure by munching at the skin, but if a whale washes up on shore, the animal’s weight can cause any open orifices to seal up.

If the whale survives the grenade harpoon, the gunner will usually pick up a high-powered rifle to finish the job. Usually whales die in their natural habitat, and generally have a positive impact, speaking in ecological terms. The ones that die at sea play essential roles in feeding deep-sea creatures, while beached whales offer researchers the opportunity to get an up-close look to advance scientific knowledge or go out with a bang (literally) if they explode. The estimated life expectancy of a killer whale is 50-80 years, while larger baleen whales like humpback, fin, or blue whales may live 80-90 years. Subscribe to our print edition here, and our iPad edition here. Whales have a tendency to explode after they die. Locals … Gas builds up in the stomach, whereafter two scenarios can follow.
