Sharks can become invisible?!


So this isn't exactly related to what we are learning in class right now, but I had to post. Up to 10% of sharks are "luminous" - they emit light from organs called photophores. This creates an optical illusion making them invisible to predators and prey! It also turns on sharks of the opposite sex. Pretty crazy.

Here's the link to the article:
