The boy has two favorite animals: elephants and sharks. Since I doodled an elephant yesterday, we felt it was only fair to show some shark love today.
According to sharkguardian.org
Shark Fact #92. Most sharks species will drown if they stop moving. Great white, mako and salmon sharks don't have the muscles they need to pump water through their mouth and over their gills. As long as they keep swimming, water keeps moving over their gills, keeping them alive.
It's a hammerhead because those are my favorite, but I checked and they are, in fact, one of the species that buccal - or cheek - muscles and therefore have to continuously swim to avoid drowning.
