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.
Topsail Island, NC, June 26, 2012. I went down to the beach at 9:30am under an overcast sky as the low tide was coming in. I found piles of Coquina clams just above the incoming tide line, lining the beach from one end to the other as far as the eye could see. At first I thought they were dead but then a full wave cycle exposed the Coquina's rabid feeding behavior. As the Coquina sensed the incoming wave, they popped up out of the sand to filter-feed on the small plants and animals that enrich the fresh Atlantic waters. The ritual repeated on each major tidal wave, about once per minute, when thousands and thousands of Coquina, all along the miles of beach stretch, were synchronized in nature's perfect order. We've been to this exact same beach many, many times for years and never witnessed this before and it did not occur again for the following five days that we were there. So we suspect this may have been a breeding activity because of the massive participation and because it is rarely observed.
Nature is cool. It is weird, but it is cool.
