Rare snail news from Dutch desert island

Dutch biologists Sylvia van Leeuwen and Wim Kuijper report today about snails on the Wadden Sea desert island Rottumerplaat.

The rare Red List species the narrow-mouthed whorl snail had been found on the island for the first time in 2006. They then were in a small area, only 15 square meter.

in late 2015, it was found that narrow-mouthed whorl snails still live on Rottumerplaat: on a much bigger area, of at least 1500 meter by 5-10 meter.

In 2006, 18 snail species were found on the island. In 2015, 20. Apart from the narrow-mouthed whorl snail, this includes four other Red List species: mouse ear snail; dun sentinel; Vertigo antivertigo; and crested vertigo.
