Sea Cucumber (IMAGE) Queen Mary University of London Caption Scientists from Queen Mary University of London (QMUL) have discovered for the first time how marine animals called sea cucumbers can rapidly change the stiffness of their body, which could provide a useful basis for developing novel biomaterials for applications in medicine. The species pictured here is of Parastichopus tremulus, which is not the type the researchers worked on. Credit M.
