| Location of Oʻahu | |
Achatinella casta was a type of air-breathing land snail. It was a land mollusk that belonged to the family Achatinellidae. This snail was special because it was endemic to Oʻahu, meaning it could only be found naturally on that one Hawaiian island. Sadly, this species is now extinct.
What was Achatinella casta?
Achatinella casta was a small snail that lived on land. Like other gastropods, it had a soft body and usually a shell. These snails were known for their beautiful, often colorful shells. They were part of a larger group of snails called Achatinella, which are all native to the Hawaiian Islands.
Where did it live?
This particular snail, Achatinella casta, lived only on the island of Oʻahu in Hawaii. Being "endemic" means it was unique to that place and didn't live anywhere else in the world. The forests of Oʻahu were its natural home.
Why is it extinct?
The "†" symbol next to its name means that Achatinella casta is now extinct. This means there are no more living individuals of this species left on Earth. The exact reasons for its extinction are not detailed here, but many native Hawaiian snails faced threats from habitat loss and new species brought to the islands. The last known sighting of this snail was in November 2017, but it is now officially considered extinct.
