Great Ramshorn Snail - Planorbarius corneus
Diameter 30 mm. The shell coils in a flat spiral. Their shells are various shades of brown with a reddish tinge caused by the presence of haemoglobin.
Inhabits small, still, weedy ponds and drains.
All year round.
These snails graze on algae by scraping rocks with a special tongue with embedded teeth called a radula. They lay their eggs in a protective mass of jelly on plants or any other underwater structure.
Fairly frequent in much of England, but fewer records from Wales and Scotland.
Common in Leicestershire and Rutland.
