The engineers used a muscle from the slug's mouth — known as the buccal muscle - that pulls against the robots internal structure.
Biofilm formation is the precursor to the growth of barnacles and other damaging organisms that must be removed through costly and time-consuming processes. In most species is a swimming veliger larva with a coiled shell which is shed at metamorphosis when the larva transforms into the adult form.
The finding could have implications for the development of new anti-bacterial industrial compounds to prevent the formation of seaslug diet biofilms on marine materials such as ship hulls, fishing traps and nets.
