Hydra

video


A while back I posted some pictures of Hydra viridis (see http://beyondthehumaneye.blogspot.com/search/label/Hydra) showing its remarkable ability to change shape. The pond that I regularly use for collecting small freshwater protists and invertebrates is currently teeming with these tentacled hunters, so I took the opportunity to shoot this short video sequence of this elastic animal in motion.
