Jeremy the snail was originally found around a compost heap in Rayne’s Park, South West London by a retired scientist from the Natural History Museum, who spotted its unique traits.Having heard about Dr Davison’s interest in snail genetics, he contacted the Nottingham scientist before sending it on in the post.Scientists are calling on gardeners across Britain to scour their plots to see if they can find another snail with an anti-clockwise shell. Snails mate head to head so there sex organs must be on the right hand side “However, they don’t really like doing this,” added Dr Davison. “From our perspective, the genetic data from offspring of two lefty snails would be far richer and more valuable to us.”Earlier this year, in research published in the journal Current Biology, Dr Davison and colleagues at universities in Edinburgh, Germany and the US, revealed they had discovered a gene that determines whether a snail’s shell twists in a clockwise or anti-clockwise direction.The same gene also affects body asymmetry in other animals – including humans – and research using these snails could offer the chance to develop our understanding of how organs are placed in the body and why this process can sometimes go wrong when some or all of the major internal organs are reversed from their normal placement.Garden snails court from 15 minutes to six hours by circling each other, touching with tentacles, and biting on the lip and genitalAnyone who thinks they have found a sinistral snail can email a picture of the snail to [email protected] or tweet it using the hashtag #snaillove. Life is not easy when you’re a sinistral mutant.Jeremy the garden snail was born with a rare genetic mutation which means his shell spirals anti-clockwise. Unless he finds another snail with a similar abnormality, he simply cannot mate.And it’s not just the aesthetics of his eccentric exterior which is putting off suitors. His left-handed make-up means his sex organ is also on the wrong side.Snails mate face-to-face, sliding past each other on the right hand side so that their genitalia can meet. To copulate Jeremy must beat one in million odds to find another snail which also has left-handed sex organs which are compatible with his own.Yet there is hope. The University of Nottingham is keen to study the genetics of left-sidedness, or ‘sinistral mutation’ and so is on the hunt for a partner for Jeremy so they can study his offspring.“This really is an exciting find – I have been studying snails for more than 20 years and I have never seen one of these before,” said Dr Angus Davison, associate professor at the university’s school of life sciences.“We are very keen to study the snail’s genetics to find out whether this is a result of a developmental glitch or whether this is a genuine inherited genetic trait. It is very rare. It might even be one in a million.“They mate in a face-to-face position and the genatalia are on the right had side of the body in a normal ‘righty’ snail and that means when you get two snails of the opposite kind trying to mate the genatalia just don’t match up. They can’t get it together.” Want the best of The Telegraph direct to your email and WhatsApp? Sign up to our free twice-daily Front Page newsletter and new audio briefings.
