Rare Snails Lay Eggs During Journey to Zoo

Rare glutinous snails, found exclusively in a single lake in Wales, started laying eggs during their journey to a zoo as part of a national effort to save the species. The unexpected event occurred during the six-hour drive to Wingham Wildlife Park near Canterbury, where approximately 12 egg pods were discovered in the transport containers.

This development is seen as a promising start for the nationwide initiative to protect these tiny creatures, which were once widespread across UK waterways but have seen their population drastically decline due to habitat disruption.

Highlights

• Rare glutinous snails began laying eggs while being transported from Wales to Kent.
• This species is found in only one UK lake, Llyn Tegid in Wales.
• Wingham Wildlife Park has initiated a breeding program to eventually reintroduce them into the wild.
• The zoo successfully established a colony, starting with just six adult snails and quickly producing 130 offspring.
• The project is part of a broader national conservation effort for the species.

Details

Glutinous snails are no larger than a fingertip and were once common throughout the UK's aquatic environments. However, habitat degradation and environmental changes have severely reduced their numbers, confining them to Llyn Tegid in Eryri National Park (Snowdonia). Wingham Wildlife Park has taken some of these wild snails to breed them in captivity with the aim of eventually releasing them back into suitable natural habitats.

Zoo officials report that the breeding efforts have started remarkably well. Assistant Curator Samantha Eden stated that she brought 24 snails from Wales in early July, and they began laying eggs during the journey. From an initial pond with just six adult snails, 130 baby snails were recently moved to start a new colony, demonstrating rapid reproduction.

Why it matters

This event is significant for the success of national conservation efforts for an endangered species. Wingham Wildlife Park is collaborating with Askham Bryan Wildlife Park, Longleat, Dudley, and Chester zoos, alongside the Freshwater Habitats Trust, to identify suitable water bodies where these snails can eventually be released. This work represents a critical step in preserving the UK's unique biodiversity.
