You slip over the side of your boat, descending deep into the dark realm
of the Earth's largest creature. Then the whale starts to sing, just
feet away from you. Photographer Flip Nicklin brings you face to face
with whales as they communicate, nurse their young, and surface
dramatically for air. Learn of the different kinds of whales, discover
how we can aid their recovery from years of overhunting, and how we can
protect their environment.
