Zebrafish adults are small, around 3-5 cm in length, and they like to be housed together in shoals. They are batch spawners capable of laying hundreds to thousands of embryos a week.
Female fish lay eggs into the water around her, where they are fertilized by the males, allowing collection the eggs as soon as they're laid.
They develop from a single cell in a fertilized egg to something that resembles a tiny fish in 24 hours. Once they are around 4-5 day post fertilization the embryos are free swimming larvae and start to catch their own food.
The transparency of zebrafish embryos is one of the leading reasons for using them for scientific research. The ability to see through the embryos allows observation of morphological changes that occur during development.
Mutations can be generated and analyzed to see what happens when a gene’s normal function is altered.
Zebrafish are vertebrates and share many of the same genes as humans.
