How humpback whales use marine habitats off the eastern coast of Africa is only partially understood, and that has become a conservation concern as offshore energy exploration expands in the region. However, a new study published in Marine Ecology Progress Series found that humpback whales that were satellite tagged off the coast of Madagascar during peak breeding season are traveling much further in the southwest Indian Ocean than previously thought. This research can help define potentially sensitive areas that should be protected from the disruption of seismic testing or other industrial development that could be destructive to the humpback population and this globally important marine habitat.
