Dolphin drifting 🐬⁣ ⁣ These dolphins are hunting in waters only a few centimetres deep, using a technique called hydroplaning. As fish move into shallower water, the dolphins usual hunting techniques no longer work. Instead they pump their tails to gain speed and hydroplane, allowing them to catch fish even in the shallowest waters. ⁣ ⁣ Footage by © BBC NHU⁣ | BBC Earth
