Whales' baleen plates disclose their dietary habits
Scientists have discovered that the baleen plates of toothless whales can reveal how these mammals adapt to environmental changes over time. By examining the baleen plates, which held a chemical record of their feeding patterns, scientists could find out how changes in the whales’ feeding habits corresponded with the changing climate cycles.
After a study involving humpback and right whales in the Pacific and Indian Ocean, they published their findings in the Frontiers in Marine Science journal.
