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.
Do whales like humans?
But in a new study, researchers compiled a list of the rich behaviours spotted in 90 different species of dolphins, whales and porpoises, and found that the bigger the species’ brain, the more complex – indeed, the more “human-like” – their lives are likely to be.
Can a human survive in the belly of a whale?
While the veracity of the story is in question, it is physically possible for a sperm whale to swallow a human whole, as they are known to swallow giant squid whole.

Can a whale swim?
Whales swim forward by flexing their tails up and down, instead of side to side as with most fish. To change direction, they move their flippers, similar to the way an airplane steers (read How Sharks Work for details). The dorsal fins, if present, serve to stabilize the whale’s body as it swims.
Do whales sleep?

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.
How long do whales sleep a day?
Humpback whales, for example, have been found resting motionless on the surface of the water for about 30 minutes. They can’t stay like that for long though, because they lose too much body temperature when inactive. By contrast, dolphins sleep at night for a couple hours at a time.
Do whales stink?
Then we smell it. The odor is blunt and pungent, almost a taste in the mouth, an unholy mingling of fart and fishiness—hundreds of gallons of air forcefully expelled from its lungs, laced with the fumes of half-digested krill, hundreds of pounds of these slow-dissolving crustaceans fermenting in its stomach.

How long can whales hold their breath?
90 minutes
Do whales drown themselves?

How long can humpbacks hold their breath?
