Immunochemical investigations on toad (Bufo) eggs: comparative studies on three species (B. bufo, B. viridis, B....

Eggs of three Bufo species (B. bufo, B. viridis and B. calamita) were examined for blood group activity. B. bufo showed distinct A activity, whereas in B. viridis and B. calamita a marked H-activity was observed. These results correspond with the zoological systematic classification of the three toad species tested.
