Inspired by a life-changing childhood experience, Gaelin Rosenwaks set off on a journey to tell the story of sperm whale families through photography and film. In the waters off Dominica, she observed eye to eye the close bond between mother and child firsthand. What she found is that these animals live in matriarchal family units made up of remarkable females that stay together for generations. Like elephants and humans, they take care of one another. Rosenwaks s years as a marine biologist, diver, and underwater filmmaker and photographer prepared her to tell this beautifully stirring story with never-before-seen photographs of the world s most marvelous ocean species.
