Danio rerio (Zebrafish)

Danio rerio, commonly known as zebrafish, is a small freshwater fish widely used in scientific research. They are valued for their transparent embryos, which develop outside the mother, allowing scientists to easily observe growth and genetic processes in real time. Zebrafish share many genetic similarities with humans, making them useful for studying development, genetics, and diseases such as cancer and neurological disorders. Their fast reproduction, ease of care, and well-mapped genome make them an important model organism in biomedical research, contributing to advances in medicine and understanding of biological functions.
