also involved in eastern hellbender conservation, and is partnered with Purdue University and Indiana's Department of Natural Resources in their efforts to repopulate this subspecies of salamander. The zoo currently has a public display of tanks holding juvenile hellbenders, which are returned to their habitat once they have reached a certain, less predated size, and an off-display adult stream containing several adult salamanders. In 2020, Mesker Park Zoo was the first facility where eastern hellbender salamanders bred naturally in human care, which the animal curators attribute to adjustments in the water parameters and sex ratio of salamanders in the artificial stream.
