Zebra fish and their life cycle by María López Alonso
The female lays eggs in the water, where the male fertilizes them. The stages of embryonic development are fast.
The females lay more than 200 eggs per week. The embryos are protected by a membrane, the chorion. After three days the embryos hatch.
They can be kept in the laborature in culture dishes thanks to their small size.
An adult is approximately 4 incles long. Unlike humans zebra fish continue to grow until death.
