Yes, in mid-November 2011, for the first time ever in captivity, 62 little hellbenders (salamanders) hatched out in Saint Louis Missouri Zoo. 120 more are expected by early December. Rivers there used to support more than 8000 hellbenders, but they were declared endangered in 2011 when fewer than 600 were estimated left. Polluted waters and illegal capture are blamed for their decline. Fully grown, at 5 or 6 years of age, adult hellbenders can be up to 2 feet long (60 centimeters).
