Zebrafish

fish · science · stripes

Tiny striped swimmers. Zebrafish are small freshwater fish with bold black and white stripes that run along their whole body. They got their name from these stripes, which look just like a zebra's pattern.

Super useful for science. Scientists love zebrafish because they're transparent when they're babies, so researchers can watch their organs develop inside their bodies. This has helped doctors learn about how all animals (including people) grow and work.

From Asian rivers. These fish come from slow-moving rivers and streams in South Asia, where they swim in groups looking for food. They're tough little fish that can handle different water conditions.

Popular pets worldwide. Zebrafish are sold in pet stores all around the world as aquarium fish under the name zebra danio. People love them because they're colorful, hardy, and fun to watch.

Big families together. In the wild, zebrafish live in schools with lots of other fish swimming together. They feel safer and happier when they have friends around.
