Lookin' for Love

(Image credit: Angus Davison/University of Nottingham)Jeremy is a rare snail, and despite many efforts by his caretakers, he is still looking for love.

Jeremy is a garden snail with left-spiraled shell, a trait that makes him one in a million. Lefty, or sinistral snails, can mate only with other lefties. However, in spite of a social media campaign that found two more "lefty" snails, Jeremy is still lonely. That's because the other two lefty snails hooked up, leaving Jeremy behind.

Luckily, researchers can still study the offspring of the lefty snails (hopefully, with Jeremy's blessing), so the scientists can determine whether this trait is inherited or a developmental glitch. [Read the full story on Jeremy's love saga and what it means for geneticists]

Star-crossed lovers?

(Image credit: Hannah Jackson)Angus Davison, an associate professor and reader in evolutionary genetics at the School of Life Sciences at the University of Nottingham in England, started a social media campaign with the hashtag #SnailLove to find Jeremy a lefty partner.

The campaign produced results. Two other lefty snails oozed forward: Lefty and Tomeu. Here, Davison holds Lefty and Jeremy.

Mating snails

Hatching snails

Lefty, their mother, influenced their shell spiral through a phenomenon known as maternal to zygotic transition (MZT). The mother's egg doesn't contain just DNA, but also cytoplasm, proteins and other components carrying her genetic signature. Early in development, the mother's genetics can influence the baby's growth.

MZT can influence egg color in birds. It can also influence the direction of shell coil in snails, Davison said.

Mom time

Jeremy and baby

This may help scientists understand what genes (if any) influence organ misplacement in humans, Davison said. [Read the full story on Jeremy's love saga and what it means for geneticists]
