Assessment of the aerial behaviors of humpback whales, Megaptera novaeangliae (Borowski, 1781), in coastal areas in Northeastern Brazil
The aim of this study was to analyze the aerial behaviors of humpback whales (Megaptera novaeangliae) in Northeastern Brazil. From July to October 2013, 113 groups, totaling 272 individuals (x̄ = 2.41; ± 1.52), were observed, including possible double counts. Groups consisting of more than three ind...
