Histochemical observations were made on the interrenal gland and liver, using 10 specimens of European spotted dogfish, Scyliorhinus canicula, collected at Plymouth Laboratory, England. Interrenal gland of the dogfish shows similar histological structure to that in the gland of other elasmobranchs. The gland contains abundant lipid droplets, and cholesterol and its esters. On the other hand, the dogfish has a liver of relatively small size (HSI: 6.06±0.54%) among elasmobranchs. But the dogfish liver includes tremendous amount of lipid droplets. Accordingly, in most specimens examined the liver looks like adipose tissue. Furthermore, brown pigment granules are often found in the liver tissue of the dogfish. From the results of the various histochemical tests, these granules were identified as melanins.
