Underwater acrobatics of world's smallest marine dolphin: watch and listen

University of Auckland scientists have used tracking data to recreate dives by a Hector’s dolphin.Animation shows a deep nighttime dive in real time using tracking information.Triangle = surfacing (you can hear the splash as it breaks the surface and the breath)Circle = moves as the dolphin dives downBlue line = dorsal side upYellow line = upside down as the dolphin barrel rolls (on the shallow dive) or swims just above the seabed (on the deep dive)Red starbursts = when the dolphin chases a fish Credit: University of Auckland
