Great Pond Snail - Lymnaea stagnalis
Shell height: 4.5 to 6 cm. Shell width: 2 to 3 cm. The aptly named Great Pond Snail is the largest pond snail in Britain. It has a shiny yellowish brown shell, with a tall, slender and pointed spire.
The great pond snail is found in still or slow-moving waters where there is plenty of aquatic vegetation. As the specific part of the Latin name, stagnalis, suggests, this species prefers stagnant water.
All year round.
It lays large gelatinous egg-masses on weeds and other objects in the pond.
It is common and widespread in England, but is scarce in Scotland and Wales.
Fairly common in Leicestershire and Rutland.
