Abstract
Abstract: 1.1. Hemoglobins from 125 species of tropical marine and freshwater fishes were analyzed electrophoretically.2.2. The mean number of hemoglobins per branchial-respiring species was 3.6, whereas aero-branchial respiring species of the Order Batrachoidiformes had a mean of 6.4.3.3. Hemoglobin polymorphism was observed in 9% of the species.4.4. The incidence of species with single hemoglobins was 11%, the highest reported from comparable studies on fish.5.5. The results are discussed with respect to the hypothesis that hemoglobin heterogeneity is adaptive for unstable environments.
