Twitter hashtag helps rare mutant 'lefty' snail find mate
A UK garden snail named Jeremy with one-in-a-million 'left-handed anti-clockwise spiralling shell' mutation has found a mate, named 'Lefty', with the same condition, after a nationwide search with the hashtag '#snaillove' was launched. Jeremy and Lefty's offspring will be used to study the genetics of this rare condition, which may help explain body asymmetry in other animals, including humans.
