As they might with most endangered animals, scientists consider the whereabouts and activities of right whales extremely important. “It is helpful to know where they go, why they go there and what they do when they’re there,” says Mark F. Baumgartner of the biology department at the Woods Hole Oceanographic Institution (WHOI).
Baumgartner and his colleagues studied the behavior of right whales and sei whales—both endangered species of baleen whales—in the waters of the Gulf of Maine to the east of Nantucket. They found that the location, the length of stay, and perhaps the very abundance of the whales may be dependent on an interesting vertical migration pattern by the copepods on which the whales feed. It seems to be a case, he said, of “how the behavior of the prey influences the behavior of the whales.” (more…)
Listen Up: Ocean Acidification Poses Little Threat to Whales’ Hearing
Contrary to some previous, highly publicized, reports, ocean acidification is not likely to worsen the hearing of whales and other animals, according to a Woods Hole Oceanographic Institution (WHOI) scientist who studies sound propagation in the ocean. (more…)
