Rare snail news from Dutch desert island

Narrow-mouthed whorl snail shells

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.
