this:

is functionally identical to the human experience of not looking both ways, getting clipped by a speeding semi, and being sent flying through the front window of the 7-11 across the street (except that the semi doesn’t turn around and eat you afterwards)

So first of all, the orca weighs the same as between two and three minivans. See? And it can reach speeds of 35 miles per hour. So. Basically anything it does to you at speed is going to completely wreck you or almost any other creature alive on the planet

But then! look at this gif of an orca doing the specific tail yeet that was mentioned

full the force required to launch a seal like that is probably lethal by itself. Right? but then the seal reaches an estimated 80 feet (24 meters) ! at which point the surface of the water itself is often lethal to humans falling from that height, so, idk about seals but i bet the fall itself is basically like getting hit with the same truck a second time.

here you can see the relative size of an adult orca and the seals they hunt this way

this is like if a soccer player kicked a house cat full force.

bonus: here’s a gif showing what the tail slap would look like from underwater, and, idk about you, but this one creeps me out. Like, it’s super cool, but also, goosebumps

may i remind you: weighs the same as three minivans. Moves as fast as suburban traffic. Hyper carnivore all meat diet, develops special unique hunting techniques for murdering many many different kinds of animals in all sizes, lots of them mammals - from bite-sized otters to the biggest whales. Close to same intelligence as a human.
