NC zookeepers work to save endangered Puerto Rican crested toads

ASHEBORO, N.C. -- One of the most important jobs of the North Carolina Zoo is saving endangered species -- that's exactly what they're doing for the Puerto Rican crested toads.

Zookeepers at the NC Zoo started at the beginning of the process and decided to speed up the mating season for the toads.

They simulated toad calls musically, and within one day, thousands of tiny tadpoles hatched.

They are expected to be shipped back to Puerto Rico to repopulate.
