Description
Summary:Correlation between the body length and the diameter of the compound eye of the Antarctic krill Euphausia superba was examined. From the samples collected in the late summer, it shows that there is an apparent exponential relationship between eye diameter and the body length. From the laboratory population, it seems that when the krill shrink, the diameter of the compound eye does not decrease. It is more reliable to use the eye diameter as krill growth index than body length. The ratio of the body length to the diameter of the compound eye offers another method for detecting the effect of shrinking in natural populations of krill.
