Please stay on topic. Coffee.

I take a look at this video once a year, after doing my taxes. It doesn't ease the pain of paying taxes, but it does make you consider what might happen if we ever got all the government we're paying for.

The initial period begins with "mobile scavengers" such as hagfish and sleeper sharks actively consuming soft tissue from the carcass. Consumption can be at a rate of 4060 kilograms (88132 lb) per day over a two-year period.[5]
Stage 2
The second stage introduces the "enrichment opportunists". These are animals which colonize the bones and surrounding sediments that have been contaminated with organic matter from the carcass and any other tissue left by the scavengers. This process can take up to two years.[5]
Stage 3
Finally "sulfophilic bacteria" anaerobically break down the lipids embedded in the bones. Instead of oxygen, they reduce dissolved sulfate SO2â
4 and excrete hydrogen sulfide. Due to the toxicity of H
2S, only resistant chemosynthetic bacteria survive. The bacterial mats provide nourishment for mussels, clams, limpets and sea snails. As whale bones are rich in lipids, representing 46% of its body weight, the final digestion stage can last between 50 and possibly 100 years.[5]
