If you're a sea snail, finding a date amid the leaves and twisting branches of Hong Kong's mangrove forests is a tricky affair. Fortunately, males of the species Littoraria ardouiniana (shown) and L. melanostoma have hit upon a good solution. During breeding season, the gastropods seem to be able to sniff out the mucus trails left behind by traveling females , researchers report online this month in Animal Behaviour. In the lab, males traced female trails more often than trails lain by other males or females of another species. These slow-moving bloodhounds (the video depicts snails moving at four times their normal speed) may be picking up on as-of-yet undiscovered pheromones in the females' mucus, the team says, hinting at a possible new Chanel fragrance: Eau du Ooze.
