What happens to a dead whale?

When whales die and sink, the whale carcasses, or whale falls, provide a sudden, concentrated food source and a bonanza for organisms in the deep sea. Different stages in the decomposition of a whale carcass support a succession of marine biological communities. Scavengers consume the soft tissue in a matter of months.

Why do they sink dead whales?

“It gives us insight, a speeded up movie of how organic carbon is processed,” Orphan says. “You have this additional advantage of knowing a 'time zero,' at least for the whales you put down there.” Researchers can observe the communities return to their baseline populations once all of the carbon has been extracted.

How do whales not drown when they eat?

Researchers found that lunge-feeding whales have an 'oral plug', a fleshy bulb in their mouths that moves backwards to seal off the upper airways during feeding, while their larynx closes to block the lower airways.

Why do dead whales fill up with gas?

Gas builds up inside the whale as its stomach contents decompose -- but due to its thick, tough blubber and skin, it can't be released. A combination of heat and the whale's own body weight can cause orifices to close up, intensifying the problem.

Do whales die fast?

Whales are huge, long-lived mammals. The blue whale is the largest animal that's ever lived on earth – it is bigger than the dinosaurs. It can live an estimated 80 to 90 years! The bowhead whale, a somewhat smaller species, may live more than 200 years.

Do whales go to shore to die?
