The ancient Nautilus. Probably one of the coolest looking critters to jet around in the sea. I’ve also learned while researching this piece, that the coloration of their shells actually helps in camouflaging them in the open ocean(i.e. Dark on top and light when viewed from below). And when you think about it, it’s a brilliant sort of time-delayed camouflage since it’s always growing?! Nature is so f@#king cool!!!
