This dataset pertains to age determination in crustaceans relies on quantification of a fluorescent "age pigment," lipofuscin, that accumulates in eye stalks of krill over time.

The ratio of lipofuscin to protein concentration is the Lipofuscin Index and is calculated for each individual organisms.
