Are killer whales friendly?

Why do Orcas 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.
Has anyone been swallowed by a whale?
The only whale that would likely be capable of swallowing a human would be a toothed whale, the sperm whale, which eats prey such as giant squid. A sperm whale did ram and sink the whale ship Essex in 1820, but there are no reliable reports of a sperm whale ever eating a human.
Can killer whales eat humans?
They want to eat you – Since you are not part of their very specific diet, killer whales have no reason to attack you. Just as a fish-eating orca won’t attack a seal that swims by, they won’t attack you either. Humans aren’t on the menu.

Health Concerns At least 160 orcas have died in captivity, even more if stillbirths are counted. … When those orcas become ill, they may be resistant to antibiotics due to those regular treatments. Resistant strains of pneumonia and other infections have been the cause of death for numerous captive orcas.

Is it safe to swim with orcas?
It should be noted orcas’ alternate name of “killer whales” is apt, and it’s not necessarily safe to swim with them or get close in small boats. It also should be noted, however, that despite several tragic killings of people by captive orcas, there’s no record of such attacks in the wild.
Can you survive inside a whale?
As you have probably gathered by now, even though it is technically possible to survive being swallowed by a whale, it’s extremely unlikely. But luckily for us, whales are generally not that interested in humans. If you are going to worry about anything eating you in the water, it should probably be sharks.
