Introduction
Zebrafish or zebra danio (danio rerio) are seen as the latest "model' for embryological development studies. These embryos have the great advantage that they develop as "see through" embryos, that is, all internal development can be clearly observed from the outside in the living embryo. Much of the early modern work using this embryo model began with the papers of Kimmel.[1][2]
Several large laboratories in the US are now developing large breeding programs to carry out "knockouts" and to find spontaneous mutants of interest.

Journals
Zebrafish "is the only peer-reviewed journal to focus on the zebrafish, which has numerous valuable features as a model organism for the study of vertebrate development. Due to its prolific reproduction and the external development of the transparent embryo, the zebrafish is a prime model for genetic and developmental studies, as well as research in toxicology and genomics. While genetically more distant from humans, the vertebrate zebrafish nevertheless has comparable organs and tissues, such as heart, kidney, pancreas, bones, and cartilage." [jour PubMed listing]
