Scientists are hoping to study the genetics of an ultra-rare garden snail are asking the public for its help in finding the lonely mollusc a mate. The snail’s unique qualities make it a one in a million find - but also impossible for it to mate with its more common counterparts. At first glance, the brown garden snail may look like any other but closer inspection of the snail’s shell reveals exactly why this creature is so special. While the shells of this common species spiral in a right-handed, clockwise direction – known as dextral – this snail is a sinistral, with a left-handed anti-clockwise spiralling shell. In essence, the ‘lefty’ snail is a mirror image of its other shell-dwelling friends.
