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.

Where are toothed whales and baleen whales found?
They are found in all of the world’s oceans, and even in some freshwater rivers. Despite their very different diets and sizes, both baleen whales (Mysticeti) and toothed whales (Odontoceti) share a common (and perhaps surprising) ancestor—land-dwelling mammals related to today’s hippos that lived over 50 million years ago.
