An underwater pokéball for capturing sea creatures

(Wyss Institute for Biologically Inspired Engineering at Harvard) The ocean is home to millions of soft-bodied creatures — jellyfish, sponges, octopuses, squid, etc. — that are difficult to study using existing equipment, which was developed for the oil and gas industry and frequently destroys the delicate animals they're meant to sample. A new device from researchers at Harvard's Wyss Institute employs a rotating, folding polyhedron to harmlessly capture and release marine life in the wild.
