Dolphins are unarguably one of the most beautiful and intellectually gifted creatures on earth. With elusive communicational skills, their language is far more extensive and complex than that of the human race. There are as many as 44 different species of dolphin; 38 oceanic dolphins and 6 types of river dolphin. One special member of this aquatic family is the Irrawaddy River dolphin.
