Reptile expert Dr Brady Barr's "miraculous" crocodile language has
helped him study all the world's 23 species of crocodilians in the
wild.
He used croc talk when he found a nest of rare baby alligators
in Anhui Province -- he mimicked the babies'
cries to call their protective mother, one of a critically
endangered species. Then he captured her, studied her, took her DNA
and released her.
Last week at Shanghai?Xintiandi's UME International
Cineplex, Dr Barr was eager to share this "expertise" in croc talk
with the audience who had watched a National Geographic TV program
covering his historic achievements in studying the endangered
ancient reptiles worldwide.
Barr has captured specimens of all species in Asia, Australia,
Subsaharan Africa, North Africa, North America, Central America and
the Caribbean, and South America. He took DNA samples, photos,
measurements, studied habitat, diet and collected other
information.
The Chinese alligator, also known as the Yangtze crocodile,
inhabits the lower ranges of the Yangtze River.
It may be the rarest of the world's crocodilians and is one of
the world's two species of alligators -- the other is the American
alligator.
Only about 150 are thought to exist in China.
They are only about two meters long at most, they eat molluscs
and snails, as well as handy ducks. Loss of habitat through
pollution, damming and development is driving them to
extinction.
Barr unexpectedly encountered a nest of 100 baby alligators -- a
gold mine for a biologist. "The babies, just the size of a candy
bar, climbed onto my hand and cried to me, as if I were their
mother. That was an amazing feeling."
The reptiles have their own language and hierarchy, he said.
The Shanghai Discovery Channel will air "Dangerous Encounters,"
four National Geographic documentaries, this month. They chronicle
Dr Barr's capture of crocs, interaction with snakes and his
adventures in the depths of caves to search for all manner of
dangerous serpents, lizards and other reptiles.
Croc talk is not difficult, he says. "It is not hard to
pronounce, just like 'ow'," the 44-year-old US scientist says,
joking. "I hope next time I come to Shanghai, we can say 'hello' to
each other in this special language. Remember, only the right
pronunciation will ensure your cordial reception, otherwise you
will be 'eaten."'
Baby crocodiles always use that sound to call their mothers and
Barr's perfect imitation lured many mother crocodiles for
study.
"Crocodiles are intelligent and complex animals," Dr Barr says.
"They're not cruel 'killing monsters' as many people think. Most
crocodiles take care of their kids even better than humans. We
should respect them and marvel at their unique beauty."
Barr says crocodiles in normal settings do not make unprovoked
attacks on humans and make sounds and movements to warn humans
away.
Poachers catch crocodiles for their valuable hide. But what has
driven Dr Barr for more than 15 years, through 50 countries and
regions is a passion to save crocodilians, including alligators,
caimans and all their variations in the wild.
They face extinction because of shrinking natural habitat and
hunting. Today, nearly one third of all croc species are
endangered.
There are so many "incredibles" about crocodiles. They are among
the oldest animals on Earth, and have lived on the planet for about
200 million years.
They have the strongest bite, about 5,000 pounds of force per
square inch.
Like many of his peers, Dr Barr was interested in dinosaurs
during his childhood. "But crocodiles survived the global
environmental changes that caused the extinction of the dinosaurs,"
he notes. "They have fabulous intelligence and strength."
Dr Barr grew up in Indiana in the United States, calling himself
"a product of America's zoos and museums." Lizards, snakes and
turtles were his boyhood companions.
He was a high school biology teacher in Indianapolis, but then
earned his PhD in biology at the University of Miami in Florida.
There he started looking at the diet of alligators in the
Everglades and realized how little the scientific community knows
about the crocodilian species.
In 1997 he joined National Geographic as a resident
herpetologist and TV host for the channel's reptile documentary
series that was aired worldwide. "What the channel seeks is real
science, real scientists and real adventure. It is not a Hollywood
production."
When he tracks across a jungle or paddles his way up a river,
searching for a unique population of crocodiles, he always works
with a local expert.
However, catching crocodiles is dangerous. Barr uses rope,
fishing nets, a remote-controlled toy car as a lure and even his
bare hands.
He was once tangled in the rope that tied the crocodile to the
bottom of the boat. "The darkness and silence was scary."
Snake encounters have been terrifying because there was no
chance of emergency medical attention. He was once bitten on the
nose by a snake -- fortunately, it was nonpoisonous.
"The snake moves so fast that you're bitten before you know
what's happened," he adds. "With crocs, you can sometimes afford to
make a mistake. But with some snakes, you make one mistake, and
you're history."
Airing of the National Geographic series means Barr will have
300 million students learning about crocodiles.
