There are fewer things that strike more fear in the hearts of humans than sharks. They’re big, ferocious, powerful killing machines with huge teeth and insatiable thirst for human blood (if Speilberg is to be believed). Now we can add ‘stealthy’ to that list. Turns out that some sharks can change the colour of their bellies, matching it to the colour of the sunlight coming from the surface. This makes them effectively invisible when viewed from below.
Yep, Invisible Sharks. There’s nothing more than needs saying. We’re all doomed.
