Cool killer whale fact: Like all cetaceans, killer whales are voluntary breathers and are “half awake” when they are resting. Their brain has the ability to split activities; half will 'sleep' while the other half controls breathing and mobility (Lyamin et al. 2008 paper abstract)

Cool humpback whale fact: The humpback whale is one of the rorquals, a family that also includes the blue whale, fin whale, Bryde's whale, sei whale, and minke whale. Rorquals take their name from the Norwegian word röyrkval, meaning "furrow whale". All members of the family have a series of longitudinal folds of skin running down their throats.
