Professional Photographer Captures Magical Photos Of Orcas Basking In A Sunset

In the oceans' inky depths lurk one of the largest animals on Earth. What animals, you might ask? Well, more than 40 species of whale spend their lives beneath the waves, surfacing only to breathe.

Interestingly enough, the more we learn about whales, the more complex they appear to be. Scientists at the University of the Witwatersrand in South Africa have discovered, for example, that their huge brains have a built-in heating system to ensure they function properly in cold seas. We also know that whales have a large repertoire of sounds, which can vary according to geographical location.
