its new home. Beck Harlan | NPR

Snot otter. Lasagna lizard. Pick
your favorite nickname for the Eastern
hellbender salamander.
They're the color of mud, and
they can grow up to 2 feet long. People call them snot otters because they're
covered in a layer of slippery mucus. Or lasagna lizards, because the crinkly
flap of skin on their sides that helps them absorb oxygen resembles a lasagna noodle.
Eastern hellbenders live
throughout the Appalachian region in the United States. Their ancestors have
been on earth for around 160 million years, but in the last several decades
their numbers have dropped dangerously in several states, primarily due to
habitat destruction. Eastern hellbenders are endangered in Maryland, Missouri,
Ohio, Illinois and Indiana.
"We started looking at
hellbender populations in the 2000's and what we found is that they were
declining rapidly, about [an] 82 percent decline," between 1998 and 2009,
explains Greg Lipps, the amphibian and reptile conservation coordinator at The
Ohio State University. "We knew if we didn't do anything that hellbenders
were going to be gone in [Ohio].”
Lipps is part of a team that
conducts "hellbender releases" in which baby salamanders are put into
healthy creeks in Ohio.
"We want to remove
hellbenders from the endangered species list here in Ohio. That plan has two
big components. One is, we have to protect the good habitat. The second part of
it is, we want to take these babies and release them back into the wild to
bolster the populations. The two things are kind of useless without each
other," says Lipps.
So, how does a scientist get his
hands on baby hellbenders?
First, Lipps collects hellbender
eggs from nests. Then, he teams up with the Toledo and Columbus
Zoos in Ohio to raise the salamanders from eggs until they are big enough
to stand a chance in the wild.
When the babies are about 3 years
old, a team of zoo staff, members of environmental groups, scientists and local
residents get together to release the hellbenders back into the Ohio creek
system.
In August, at least 20 people
huddled along a creek bank in southeastern Ohio waiting for Lipps to give
instructions. Local kids jostled for position around coolers full of
hellbenders, trying to get a quick look.
Scientists in wet suits and
snorkels made their way up the creek looking for suitable rocks to put the
hellbenders under. When they found a good rock, kids carefully brought over the
hellbenders in small nets.
The mood was hopeful and excited.
Each animal has a tiny
transmitter beneath its skin, similar to a microchip
in a pet. The transmitter allows the team to go back to the creek and
monitor the hellbenders.
Lipps remembers the first time he
did a hellbender release, "I went back and re-captured one of those
animals, and realized 'We put it out here, and a year later I'm catching it and
it has grown, and lived on its own!' I wasn't ready for the impact that would
have.”
"Wow," he remembers
thinking as he looked at the healthy salamander, "this animal is now at
home.”
Lipps and other scientists
caution that, although releases are helpful, there is a lot more to be done to
assure threatened amphibians bounce back. Hellbenders aren't the only
amphibians in trouble. It's estimated that a third
of all amphibian species are in decline. Habitat destruction, pollution and
disease are some of the players to blame.
"What we're doing today [is]
we're buying ourselves time," says Lipps. "These animals are going to
survive about 30 years, which gives us a lot of time to get the creeks
cleaner.”
After the last hellbender was let
go at the August release, the entire group gathered around to eat cake. It had
a picture of a hellbender on it, and said in icing "Welcome To Our Gene
Pool.”
Hopefully the newly released
salamanders will grow up, find mates and expand that gene pool by making lots
of little snot otters and lasagna lizards of their own.
