They can swim, but they can also move over a surface. They do so by temporarily clamping themselves to the surface in question by exuding a sticky substance, a sort of protein-based biological cement. The mark left by this cement on a surface is known as a ‘footprint’. This footprint contains chemical substances that attract other larvae. The first footprint on a surface is therefore the first step in the colonization of the surface concerned.
