You know when you are swimming in the ocean and you feel like weird little sea creatures are touching your feet? Not to freak you out, but maybe they are. This video, taken in 2012, has resurfaced and shows hundreds of clams pretty much emerging out of nowhere. It will make you never want to walk on sand again. 

According to the description of the video on YouTube, these clams were actually breeding, so they were making even more scary clams.
