How do whales die of old age?
Cetaceans can simply die from old age. Their lifespan ranges from a few decades for harbour porpoises to over 200 years in case of bowhead whales. Furthermore, live individuals can die naturally from asphyxiation during individual and mass stranding events.

Why do whales not eat humans?
There are a few theories about why orcas don’t attack humans in the wild, but they generally come down to the idea that orcas are fussy eaters and only tend to sample what their mothers teach them is safe. Since humans would never have qualified as a reliable food source, our species was never sampled.
How do you get rid of whale carcass?
