Jack S. Grove

A marine biologist and professional naturalist, Jack has spent much of the past two decades traveling on, and lecturing about, the world's oceans. Cofounder of Zegrahm Expeditions and research associate in the Section of Fishes at the Los Angeles County Museum of Natural History, Jack is a leading authority on the fishes and marine environments of the eastern tropical Pacific. For seven years he lived in the Galapagos, where he carried out extensive marine biological studies. In 1997 Stanford University Press published his comprehensive volume The Fishes of the Galapagos Islands, and he received his Ph.D. from Pacific Western University. A true adventurer and Fellow of The Explorers Club, Jack has led numerous expeditions to the remote corners of the world, participating in polar expeditions as marine naturalist, photographer, and expedition leader, as well as working with noted scientists and explorers such as Jean-Michel Cousteau. Jack is an avid scuba diver, certified dive master, and dedicated conservationist. In 2002 he was one of 57 scientists invited by the World Conservation Union (IUCN) to participate in a conference in Hanoi to discuss a strategy for the preservation of marine biodiversity. When not traveling, he manages his own photography business in the Florida Keys.

Greg Estes

Greg has served as a licensed naturalist guide in the Galapagos Islands since 1982. After graduating with a degree in biology from the University of London, he led the Cambridge Darwin Centenary Galapagos Expedition of 1982, which studied the feeding ecology of marine iguanas. He has extensively researched Charles Darwin and is currently writing a book on Darwin and the Galapagos. Greg has participated in several other research projects, including studies of sperm whales and the dark-rumped petrel, a seabird endangered due to the presence of introduced animals. Maker of the Galapagos video Timeless & Fearless, Greg has been active in saving the Galapagos marine environment, which is becoming increasingly threatened by the impact of indiscriminate illegal fishing. He recently filmed the evacuation of the giant tortoises that were being threatened by the lava flow from the eruption of Cerro Azul volcano on the island of Isabela. Greg has traveled extensively throughout Europe, North America, Central and South America, and northern Africa.
