Imagine a snail that's big enough to fit in your hand! Powelliphanta superba is a very special type of large land snail. It's a carnivore, meaning it eats other small creatures.
This amazing snail lives only in one place: the South Island of New Zealand. This makes it an endemic species, found nowhere else in the world. It belongs to the Rhytididae family of snails.

Meet the Giant Snail: Powelliphanta Superba
Powelliphanta superba is one of the largest land snails you can find. These snails are known for their beautiful, shiny shells. They are also unique because they are hunters!
What is a Powelliphanta Snail?
Powelliphanta snails are a group of large, air-breathing land snails. They are part of the Gastropoda class, which includes all snails and slugs. Unlike many snails, they don't eat plants.
Instead, they use a special rasping tongue to hunt. They mostly eat earthworms and other small invertebrates. This makes them important predators in their forest homes.
Where Do They Live?
These snails live in the damp, cool forests of New Zealand's South Island. They prefer places with lots of leaf litter and moss. This helps them stay moist and find their prey.
They often hide during the day and come out at night to hunt. Their habitat is very important for their survival.
Different Kinds of Superba Snails
Scientists have found five different types, or subspecies, of Powelliphanta superba. Each subspecies might look slightly different or live in a specific area. They are all very rare.
Here are the five recognized subspecies:
- Powelliphanta superba harveyi
- Powelliphanta superba mouatae
- Powelliphanta superba prouseorum
- Powelliphanta superba richardsoni
- Powelliphanta superba superba
About Their Eggs
The eggs of Powelliphanta superba are oval-shaped. They are quite large for a snail egg. Each egg is usually about 14 millimeters long and 12 millimeters wide.
The snails lay these eggs in damp, hidden spots in the forest. This helps protect the developing snails inside.
Why Are They Endangered?
All five subspecies of Powelliphanta superba are in danger. The New Zealand Department of Conservation lists them as Nationally Endangered. This means they are at high risk of disappearing forever.
Their main threats include habitat loss and predators. Introduced animals like rats and possums can eat these slow-moving snails. It's important to protect their homes to help them survive.
