Nashville Zoo Makes History with First Captive Breeding of Eastern Hellbenders!


Nashville Zoo is pleased to announce the captive breeding of Eastern Hellbenders for the first time as well as the first controlled breeding of any Hellbenders using biotechnology. The two Hellbenders were successfully hatched from eggs produced and artificially fertilized from the Zoo’s long-term captive animals.

“The successful hatching of the two Hellbenders is a result of a long-term collaborative project with a group of international researchers dedicated to saving this species,” said Dale McGinnity, ectotherm curator at Nashville Zoo. “This is an important first step and is in line with the Zoo’s commitment to the conservation and propagation of rare species.”

The two offspring were produced from a group of four Hellbenders living in an off-exhibit facility at the Zoo. 

“It has taken five years to develop assisted reproductive technologies for captive hellbenders,” said McGinnity. “We hope that with further refinement over the next few years, this species can be reliably reproduced using these techniques. This technology may then be used with a gene bank of cryopreserved sperm for Eastern hellbenders housed at the Nashville Zoo, to produce genetically diverse and fit offspring to suit various conservation needs.”
