Darwin's Amazing Animals S2019E04 - Shrouded in Mystery -- River Dolphins, The Amazon

The Darwin team heads to Peru hoping to catch a glimpse of the elusive Amazon river dolphin. These freshwater gliders are descended from sea dwellers cut off from their environment by crustal movements eons ago. For the first time ever, the rarely-seen mammal's hunting habits are captured on video. Then, a "group date," some romantic behavior and a baby dolphin. All hearts melt when 10 of these gentle creatures pay a visit to a small dock to feed on fish scraps and play with the local children.
