New Zealand Mud-Snail

DCIM101MEDIA

The New Zealand Mud Snail is an extremely tolerant species. It is native to New Zealand and came to Britain in drinking water barrels transported from Australia. It is now one of the most common aquatic snails in the country. Its ability to withstand desiccation and thrive in a range of temperatures makes it a successful invasive species which often dominates aquatic gastropod communities. They have been recorded at Dorchester, Stone, Eythrope Lake, Wheatley, and Shabbington in the River Thame catchment.
