People Create 3D Hats For Sea Urchins After Finding Out They Use Shells As Hats

When Twitter user, @ok_girlfriend, who also happens to be a biologist, revealed that she just discovered that, "sea urchins naturally use shells as hats to make them feel safer and camouflaged so some aquarist had the genius idea to make them tiny hats." The aquarists 3D printed hats for these little sea creatures and it's indeed genius! We can't get enough of these little sea urchins donning tiny hats! 

Lately, we've been bunnies in hats, snakes in hats, and even hedgehogs in hats -- seems like we have another animal to add to the tiny hat-wearing collection
