1. Invisibility Cloak Sea Sapphires

Who needs Harry Potter's invisibility cloak when you can learn from the masters of disguise themselves - the male sea sapphires? These iridescent critters perform a vanishing act that would put Dynamo to shame: The secret lies in their skin, which is made up of alternating layers of hexagonal crystals filled with cytoplasm. Changes in the depth of the cytoplasm create varying hues, and when light hits these magicians of the sea at a 45-degree angle, they shift the visible colors into the ultraviolet range, becoming invisible to the naked eye!

It's always a party under the sea, even at night: marine species communicate, defend, and lure prey through a rave-like bioluminescence, resulting from a chemical reaction that combines oxygen and luciferin, and dinoflagellates are the little DJs triggering the glow, lighting up beaches and red tides with their illuminating beats.
