Still Waters Posted March 29, 2020 #1 Share Posted March 29, 2020 Ever wondered how a growing horseshoe crab wriggles its way out of a shell that's grown too small? A new timelapse video lets you watch the fascinating process in action as a young horseshoe crab moults, leaving you wondering how it even fit into the shell it leaves behind. In the wild, this process can take hours. The video - filmed by marine biologist Bailey Steinworth of the University of Florida - has been condensed down to just 16 seconds, so you can watch the little crustacean, just one or two years of age, wriggle out of its old skin. https://www.sciencealert.com/watch-this-amazing-timelapse-of-a-baby-horseshoe-crab-moulting-its-shell 4 3 Link to comment Share on other sites More sharing options...
