Description
Jia-Wei Xu, Jie Wang, and Yun-Wei Dong settle a snail identity case in this 2024 study. A shore snail found north of the Yangtze River mouth looks almost exactly like a wide-ranging relative, and single gene tests gave mixed answers. The team joined three-dimensional shell scans with whole-genome data to decide whether it is truly a separate species.
Shell shapes differed clearly between the two forms. Gene data split them into distinct clusters, and the gap between forms was far larger than gaps seen in known hidden species of snails. Some differing genes touch on reproduction and binding, which fits separate evolution. A third form sat between the two. The authors conclude the northern snail is a hidden species formed by geographic split.
