HONOLULU - Leaping lizards!

Honolulu Zoo welcomed three Japanese giant Salamanders Monday. 

They're a national treasure, an endangered species in Japan and a gift from the Hiroshima Zoo, Honolulu's sister city, in exchange for blue-macaws. 

The salamanders are part of the new Ectotherm Exhibit,  part of the zoo's wide range of reptiles.

"The zoo is about educating folks, conservation and gathering together and celebrating," Honolulu mayor Kirk Caldwell said. 

Japanese giant Salamanders grow to about 5-feet-long.

Honolulu Zoo hopes to be the first facility outside Japan to successfully breed them in captivity.
