Sperm Whales

For centuries, we have been fascinated by the sperm whale—the world’s largest toothed predator. Now you can experience an intimate underwater journey to connect with these majestic and gentle goliaths.

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.

Gaelin Rosenwaks is a marine scientist, explorer, photographer, filmmaker, and founder of Global Ocean Exploration, which conducts expeditions in every ocean to alert the public to the challenges facing our oceans. She has appeared as an expert on the Discovery Channel, the Science Channel, CBS News, and the National Geographic Channel. Her forthcoming documentary, Finding Physty, will release in 2022. Carl Safina’s nonfiction about the living world has won him a MacArthur Foundation “genius grant,” as well as Pew, Guggenheim, and National Science Foundation fellowships. His writing appears in the New York Times, Time, Audubon, and National Geographic, and his PBS series Saving the Ocean can be viewed online.
