Caleb McMahan

Head of Zoological Collections; Collections Manager, Fishes

Gantz Family Collections Center
Evolutionary Biology

Caleb is an integrative tropical biologist interested in the evolution, ecology, and distributions of fishes. While most of his work centers around the systematics, taxonomy, and historical biogeography of fishes, he collaborates with scientists active in areas of study such as paleontology, physiology, genomics, environmental science, and behavior. These interdisciplinary approaches offer the most toward enhancing our understanding of biodiversity. He works primarily with Neotropical freshwater fishes of Mexico, Central and South America.
