Charles Potter came to the Smithsonian National Museum of Natural History in the early 1970s after finishing his undergraduate degree in zoology from the State University of New York and Syracuse University. He is responsible for supervision of collection management activities relating to marine mammals, including accessions, specimen preparation, cataloging, specimen installations, curation, loans, information requests, and assisting visitors. Together with James Mead, Potter helped establish a national marine mammal stranding network that is now administered by the National Marine Fisheries Service. Since Potter and Mead have been at the Smithsonian, the marine mammal collection has become the world’s largest and most comprehensive collection of its kind. Potter’s field work has taken him from the North Pacific to the tropics and the Antarctic. With colleagues at the Fisheries Service, he has been actively working to reduce the incidental take of marine mammals in commercial fisheries. In addition to his duties as the collection manager for marine mammals, he is working on bottlenose dolphin zoogeography and feeding ecology. Most recently he has been working with nations of the lower Caribbean to establish a multinational response to marine mammal events.

About Dolphins, Porpoises, and Whales (Infraorder Cetacea): Body Plan

Cetaceans evolved from land mammals about 50 million years ago, making the transition to water through a variety of adaptations. A modern cetacean is so streamlined for swimming that it looks like a fish, despite its terrestrial origins. Its head is connected smoothly to its body, with no neck or shoulders showing. Nothing sticks out of a cetacean's body other than fins and a tail. External ears have been replaced by holes leading to inner ears. Male reproductive organs and female teats are housed behind slits. Cetaceans have body hair during development, but lose it as adults, even though they live in extremely cold water. Instead of insulating hair, they rely on a suit of body fat (blubber) just under their skin. Cetaceans include the largest mammal ever to have lived on earth (the blue whale), thanks to the support that water provides. Air, less dense than water, could never support a land animal the size of a whale.
