Squash’s killer “nick shot” has a formula. It’s all about height and timing, a new study shows.

Two killer whales are shown rubbing a small piece of brown kelp between their bodies. One whale is to the upper left. The other is to the bottom right. The second whale's nose comes about halfway up the first's body, lining up with its dorsal fin.

Killer whales may use kelp brushes to slough off rough skin
