Joy S. Reidenberg is an American comparative anatomist specializing in the vocal and breathing apparatus of mammals, particularly cetaceans (whales, including dolphins and porpoises). She is best known as the Comparative Anatomist in the TV science documentary series Inside Nature's Giants. In this series, she performed dissections of the animals to demonstrate anatomy, and explained how these adaptations function in live animals.
Reidenberg became interested in animal science and art as a high school student. She earned a bachelor's degree (B.A.) from Cornell University in 1983, a master's (M.Phil.) from the Mount Sinai School of Medicine Graduate Program in Biological Sciences in 1985, and a doctorate (Ph.D.) in Biomedical Sciences: Anatomy in 1988. Her dissertation advisor was the noted anthropologist Jeffrey Laitman. Reidenberg was a well-respected researcher by 2009, when a British production company approached her about coming to Ireland on a short notice to help dissect a 19.8 m (65 ft) fin whale that had washed up on the south coast. She conducted the dissection, and the company was so happy with her performance that they asked her to become a regular contributor to Inside Nature's Giants, dissecting a variety of animals (18 episodes in total), including: fin whale, sperm whale, lion, tiger, elephant, giraffe, hippo, crocodile, python, great white shark, giant squid, camel, kangaroo, cassowary, baboon, leatherback sea turtle, polar bear, race horse, giant jungle insects. She also starred in the 4 episode series "Sex in the Wild" (on PBS in the USA), also known as "Born in the Wild" (on Channel 4 in the UK), about animal reproduction in elephants, orangutans (and other primates), dolphins (and other whales), and kangaroos (and other marsupials). She was also featured in a 3-day live series called "Big Blue Live" on PBS about marinelife in Monterey Bay, California.
Reidenberg currently works in New York City and is a professor at the Icahn School of Medicine at Mount Sinai's Center for Anatomy and Functional Morphology. where she teaches in the Structures Course (Gross Anatomy, Histology, Embryology, and Imaging). She is also the Course Director for General Anatomy at the New York College of Podiatric Medicine.
