Beautiful Hector’s dolphins are filmed during a boat tour. Listen to their breathing and their communication underwater. This species is endemic to New Zealand and usually they are near the coast, making it very easy to see them. Unfortunately the Maui’s dolphin, a subspecies of the Hector’s dolphin is close to extinction because the pollution, habitat modification and mainly because they get caught in fishing nets, sometimes even not operational nets that are left behind by careless fisherman.
