In Depth

       Maiabalaena is a genus of whale that lived in waters around North America during the Oligocene period.‭ ‬Maiabalaena is noted for having neither teeth‭ ‬nor baleen,‭ ‬with the genus describers postulating that whales may have lost teeth before developing baleen.‭ ‬Maiabalaena is thought to have been a suction feeder,‭ ‬opening its mouth wide and fast so that the vacuum created sucks in any nearby fish or other aquatic organisms into the mouth.
