Orcas May Devour Marine Mammals, But They Typically Avoid Harming Humans

Orcas, or killer whales, are fierce apex predators capable of taking down almost any prey. In the wild, though, they aren't known for attacking humans.

In recent years, orca whales have repeatedly made headlines after attacking — and, in several cases, capsizing — ships off the coast of Spain and Portugal.  

Though none of these incidents involved direct harm to any humans, the belligerent behavior caused a stir, prompting many to once again question the threat marine mammals pose to humans. After all, orcas (Orcinus orca), also known as killer whales, sit at the top of the marine food web, and these highly-efficient apex predators are capable of adapting to overcome almost any prey. Still, does that mean that human is on the orca menu? 

Fortunately for us, orcas aren’t known for attacking (or eating) humans: Despite their reputation for devouring other marine mammals, they almost never attack people in the wild.

Much like how great white sharks favor seals' blubber-rich hides, and generally don’t target less-fatty hominids like us, experts also believe that killer whales just aren’t as drawn to human flesh when compared with other fare like, say, nutrient-rich salmon.
