So on the top is an image of one of the types of molecules that the animals are using to make their glue, and what they are is they're very long molecules, they're called proteins, and these proteins happen to have some fairly unique parts in them that bring about the adhesive properties.
L'image du haut montre un des types de molécules que l'on retrouve dans la colle de ces animaux, ce sont de très longues molécules,  appelées protéines, et ces protéines ont des parties assez uniques qui contiennent des propriétés adhésives.
