David G. Barker

David G. Barker (born January 6, 1952) is an American herpetologist specialized in pythons and rattlesnakes.

Barker graduated in biology at the University of Texas at Arlington, where he additionally served as an instructor in the Department of Biology, and as a preparator in the Museum of Herpetology. From 1975 to 1984 he worked at the Dallas Zoo as its public lecturer and as supervisor in the Reptile House and Children’s Zoo. In 1988 he became Curator of Education at the Gladys Porter Zoo. In 1990 he and his wife, biologist Tracy M. Barker, founded Vida Preciosa International, Inc [VPI], an enterprise dedicated to the research necessary to establish self-sustaining captive populations of pythons and boas. This facility became one of the largest and most diverse collection of pythons in the world; in 1997, the Barkers and their work at VPI were featured in a National Geographic Television documentary titled “Passion for Pythons”. They managed to reproduce 32 of the 52 recognized taxa of pythons. Among them, the first ever reproduction of 12 taxa.

Next to extensive studies on reptiles in captivity, Barker did field work in the United States,Mexico,Indonesia and Australia. His main areas of research are systematics, taxonomy, natural history, animal behavior, morphology, reproductive physiology, captive breeding and animal and plant conservation.

In 1998 he co-authored the description of a new species of monitor lizard: Varanus yuwonoi and in 2000 the description of three new species of pythons: Morelia clastolepis, Morelia nauta and Morelia tracyae. The later is named in honor of his wife Tracy.
