Etheria elliptica is a special type of oyster that lives in fresh water. It's part of a group of animals called mollusks, which also includes snails and clams. This unique oyster is the only species in its group, called Etheria.
You can find Etheria elliptica oysters across many parts of Africa and the island of Madagascar. They were first officially described by a scientist named Jean-Baptiste Lamarck in 1807. These oysters make their homes in big river systems like the Nile, and in large lakes such as Lake Tanganyika and Lake Victoria. They also live in countries like Chad, Niger, Senegal, and Angola.

What are Freshwater Oysters?
Freshwater oysters are a kind of bivalve. This means they have two shells that are hinged together. Unlike the oysters you might eat from the ocean, these oysters live only in rivers and lakes. They are an important part of the freshwater ecosystems where they live.
How Etheria elliptica is Special
Etheria elliptica is known for its unusual shell. It often grows in irregular shapes, attaching itself firmly to rocks or other hard surfaces in the water. This makes them look quite different from the smooth, round shells of many other oysters. They filter water to get their food, which helps keep the water clean.
Where Etheria elliptica Lives
These freshwater oysters are found in many different parts of Africa. They prefer areas with flowing water, like rivers, but also live in large lakes. Their wide distribution shows how adaptable they are to various freshwater environments.
African River Basins
- Nile River: This famous river is home to Etheria elliptica.
- Lake Tanganyika: One of the deepest and oldest lakes in the world.
- Lake Victoria: The largest lake in Africa by area.
- Other Countries: They are also found in rivers and lakes in Chad, Zaire (now the Democratic Republic of the Congo), Niger, Senegal, and Angola.
A Look into the Past: Etheria Fossils
Scientists have found fossils of Etheria oysters in Africa. These fossils help us learn about Earth's history. Some of the oldest Etheria fossils are about 3 to 5 million years old. They were found near Lake Turkana.
Ancient Discoveries
The very first Etheria fossils appeared during a time called the Miocene epoch. This was millions of years ago. These early fossils were discovered in the northeastern part of what is now the Democratic Republic of the Congo. Studying these fossils helps experts understand how these oysters have changed over millions of years. It also tells us about the ancient environments they lived in.
