Other Identifying Features: Shells are “D” shaped, and typically have dark and light stripes.
What do quagga mussels do to a lake?

What is the difference between quagga and zebra?
Zebra mussels prefer to attach to a hard surface , while quagga mussels can live on soft bottoms, such as sand or silt. Zebra mussels also prefer warmer water temperatures and do not grow as big as quagga mussels.
What are quagga’s predators?
Quaggas cannot be ordered, fed, or aged like most prehistoric creatures can. As such, they will simply become an adult a short time after being born, like a vanilla animal. They behave like regular Minecraft horses, and run away when attacked. Their predators include Titanis, Phorusrhacos, and Kelenken as well as most other prehistoric predators. Quaggas can wear saddles, horse armor, and chests.
