The Dominican Sperm Whale Project was initiated by Dr. Shane Gero and Dr. Hal Whitehead in 2005 to learn more about these mysterious ocean giants. The population of whales in the Caribbean has given us the unique opportunity to live among sperm whales and, for the first time, to come to know them not just as animals, but as individuals within families. Our program is the first to have followed families of whales across years. Now nine years into the program, we have followed many calves from birth through weaning and we now know that some individuals have been using the region since 1984. Having spent thousands of hours with over 20 different sperm whale families, we have uncovered mysteries about the sperm whales’ diet, genetics, social relationships, and dialects.
