Useless Fish With Big Eyes

In particular, medaka (Oryzias latipes) embryos and juveniles are widely used to address questions about embryonic development in other species.

Earlier research discussed medaka eyes but this month the fish has helped scientists understand the damaging effects of radiation on the DNA of cells. It has helped them explain why the cells of some individuals are more sensitive to radiation exposure while cells of others are more resistant to those effects, or how low doses of radiation over longer periods of time affect DNA damage and repair.

  1. Hi! I saw the picture of the fish on this page ( ) and I was wondering if you knew something about the study that was at the origin of this picture. I’m working on the fish spinal nerves development and I’m trying to find the best way to visualize them…

    Thank you!
