The effect of an evolutionary adaptation to low environmental temperature on the development of lymphoid organs was examined in Harpagifer antarcticus from Signy Island (South Orkney Islands; 60° 43′S, 45° 38′W). Thymus, pronephric kidney and spleen were typical, both in position and structural development, of those observed in warmer-water teleosts. The pronephric kidney was the first organ to be infiltrated by leucocytes, at 1 h post-hatch, though the infiltration of the thymic epithelia and the development of the splenic anlage were not observed until 4 weeks post-hatch. Full development of the lymphoid organs was not achieved until the juvenile stage. Although an increased infiltration of the thymus, by subepithelial connective tissues ...
