Alligator Snappers Need Your Help !
Macrochelys temminckii or the Alligator Snapping Turtle is not the
huggable creature that most of us find attractive. As Richard
Conniff said it in his March ’99 National Geographic Article
Swamp Thing, “You would not put one in a petting zoo unless
maybe you wanted the children to learn to count without their
fingers”(Conniff 123). It may not be the friendliest of
creatures, but it has made its home in the rivers and streams
that drain into the Gulf of Mexico for millions of years before
man ever stepped foot on this continent. Unfortunately, if
decisive action isn’t taken soon, man will be the reason that it
disappears from the only place on earth that it naturally exists.

Man is the sole reason this creature’s future is threatened.
Overexploitation and habitat loss have both placed a burden
on this species from which it will not recover if we do not do
more to regulate its harvest and preserve its natural habitat.
ALLIGATOR SNAPPER FACTS

Largest fresh water turtle in North America. Lives only in US
rivers, lakes, and streams that empty into the Gulf of Mexico.

Feeds mainly on fish, but will eat almost anything

Spends most of its life in the water leaving only to lay eggs.
Females bury large clutches of white hard-shelled eggs in
riverbanks every other year.

Sex of young is determined by the temperature in the nest

Adults reach sexual maturity between 11-13 years and may live
more than a century

Larger than the common snapping turtle, with a much larger head
and a wormlike fishing lure on the surface of its tongue, with
which it lures fish directly into its mouth
THE HUMAN THREAT
Overexploitation and habitat loss are the primary threats to
this species; however, commercial harvest for the food and pet
industries have taken the most dramatic toll on existing
populations of the turtle across its range.
Humans have harvested the alligator snapping turtle as a food
source for a long time, but the industry increased dramatically
in the 60’s and 70’s when the Campbell’s Soup Company
began producing frozen turtle soup (Reed et al. 5). In fact, the
turtle was such a popular ingredient in soup and picante sauce
that some populations were completely wiped out (Conniff
120).
The problem with the commercial harvest of this species is
that these animals do not reach sexual maturity until they are
11-13 years of age. Research indicates that harvest rates of 2
percent per year of adult females will result in significant

Loosely regulated commercial harvesting in Louisiana poses a
significant threat to future populations.
(Reed et al. 3)
population declines (US F & W 74701). In Georgia, three to
four tons of alligator snapper were taken annually from the
Flint River alone until it could no longer sustain the demand
(Reed et al. 5), and TRAFFIC reported in 2000 that over
23,000 live, adult individuals were exported to Hong Kong and
Japan for both food and for the pet trade (US F & W 74701).
This level of commercial harvest cannot be sustained
indefinitely, and although most states within its range offer
some protection, Louisiana requires only a fishing license for
the unlimited harvest of individuals at least 15 inches in length
(Reed et al. 7).
At this rate of commercial exploitation, our grandchildren will
not know this species unless they read about it.
ENDANGERED HABITAT
The range of the Alligator Snapping Turtle includes the
southeastern coniferous forests and coastal grasslands from
Texas to Florida and is limited to the rivers and streams that
empty into the Gulf of Mexico. Although it extends as far
north as Illinois, very few individuals are still found in the
northern extremes of its range.
Man has increasingly put pressure on this habitat. The World
Wildlife Fund reported in 2001 that over 98% of the
southeastern conifer forest has been converted to agricultural
use or has been modified by urban development (Dinerstein).
Commercial and agricultural development of the turtle’s
native habitat as well as river and bankside modifications that
reduce nesting areas are greatly contributing to the decline of
the species (US F & W 74701).
The human population in this region is booming, and along
with it comes additional pressures on this habitat. “Runoff,
water supply issues, suburban sprawl, unchecked road
construction, unsustainable agricultural and forestry practices,
dams, mining, and pollution threaten the aquatic life that live
beneath regions waters” (Dinerstein). The alligator snapping
turtle is part of that mix.
The combined effect of the pressure that man has placed on
the species through overexploitation and habitat loss is a
recipe for the extinction of the species. We have the ability
and the responsibility to control that threat.
