Secret lives under the sea

90 different species of whales and dolphins are found throughout the world’s oceans and major river systems. Welcome to their world.

We still know relatively little about many of these species. Some have only been identified from bones and live in the deepest and most remote places in the ocean. Only by finding out more about their lives can we develop meaningful conservation measures that will protect them and their homes.
