ON THE KIDNEY AND THE ADRENOCORTICAL TISSUE OF TOOTHED SMELT, OSMERUS MORDAX DENTEX AND SURF SMELT, HYPOMESUS PRETIOSUS JAPONICUS AND THEIR COLD ADAPTATION (Twelfth Symposium on Polar Biology)
The kindneys and the adrenocortical tissues of toothed smelt, Osmerus mordax dentex and surf smelt, Hypornesus pretiosus japonicus were investigated by light microscopy. Their kidneys, which are glomerular, show no changes in the Bowman's capsules and glomeruli between the fishes caught in summ...
