False-colour scanning electron micrograph of a single barb of the hooked fruit of cleavers or goosegrass,Galium aparine,grasping a strand of Shetland wool. Commonly known as a burr,the fruit contains a single seed. It is dispersed by means of the hooks on its surface,which attach to animal fur or human clothing & are thus transported far & wide. The fruit may also pass undamaged through the digestive system of some animals. The synthetic material used in the clothing industry as a fastener,is based on the same principle as the burr.
