The zebrafish is important in studying develop-mental origins of health and disease. Their embryos are transparent and develop outside the body, allowing simple study of the developing embryo. Zebrafish research provides a unique visual approach to under-standing the developmental defects in adult diseases and age-related abnormalities, such as cardiovascular diseases. Fish are the third most commonly used protected species in research after mice and rats: other types of fish are widely used in safety tests for environmental protection. [all fish: 490,944]
