Abstract
Lymphomyeloid organs of the Antarctic fish Trematomus bernacchii were studied with the aim of analysing some morphological aspects related t o adaptation to low environmental temperature. The thymus of T. bernac chii was flattened, incompletely lobated and scarcely regionalised. It was filled by lymphoid elements intermingled with stromal elements. T he head kidney appeared highly vascularised and mainly lymphopoietic. The spleen appeared mainly erythropoietic, with scarcely developed are as of white pulp.
