Amphibians - frogs,
toads, and salamanders - on the other hand, have moist skin, which
allows water and air to pass in and out, and no claws on their toes.
The word "amphibian" originates from two Greek words, "amphi" meaning
"both" and "bios" meaning "life". Thus, the term "living a double life"
is used in reference to amphibians. Nearly all amphibians go through a
larval stage, during the first part of their life, which is usually
lived in water, (such as the tadpole of the frog), before they change
into their adult form, and live on land. Among the changes amphibians go
through in the larval stage which results in the young animal taking on
the appearance of an adult includes the replacement of gills by other
respiratory organs, such as the lungs; the formation of eyelids; and in
toads and frogs, the tail disappears.
Wet weather is the best time to spot amphibians.
Reptiles:
Crocodilians
There are two native crocodilians in the U.S. - the American
Alligator and the American Crocodile, neither of which are native to
Kentucky.
Reptiles:
Lizards
Lizards generally have
long slender bodies tapering into a narrow pointed tail, which breaks
off easily under the slightest pressure. Legless, or worm lizards
resemble snakes, but have moveable eyelids and moist skin. Skinks are
lizards and so are iguanas.
Kentucky's climate limits the availability of proper habitats for
most members of the lizard family. Only eight of the Earth's 4300 known
species of lizards, live in
Kentucky, five of which are skinks: Broadhead Skink, Coal Skink,
Five-lined Skink, Ground Skink; and the Southeastern Five-lined Skink.
Kentucky is home to one known type of legless lizard, the Eastern
Slender Glass Lizard; one iguana, the Northern Fence Lizard; and one
teiid lizard, the Six-lined Racerunner.
On the other hand, salamanders, amphibian look-a-likes of the
reptilian lizards, are more abundant in the Bluegrass State with 33
species, of the approximately 380 known on the planet, taking up
residence here. Other amphibians in the state include species of toads
and frogs. (SEE BELOW.)
Reptiles: Snakes
Snakes are a close relative of the lizards, but have no legs or
eyelids. Different species of snakes are adapted to most every habitat
on the planet and live on every continent except Antarctica.
Kentucky has over 30 known
native snake species. Our only poisonous snakes - the copperhead,
the cottonmouth and the rattlesnake - are all pit vipers. Pit vipers are
distinguished by the "pits" on each side of the snake's head between the
eye and nostril. Learn to identify the poisonous snakes in your area and
avoid them whenever possible. A bite from one of these venomous snakes
is rare and seldom fatal. However, the bites can cause a human to become
seriously ill.
The UK College of Agriculture Cooperative Extension Service maintains
a web site containing photographs and information on all species found
in the state. Visit their site, Kentucky Snakes, for help in
identifying native species.
Reptiles: Turtles
Turtles are reptiles with a protective shell. They are slow to mature
and can live to be over a hundred years old. Found on every continent
except Australia, there are over 250 turtle species known on the planet.
In the United States we use the term "tortoise" to refer to land turtles
and you sometimes, (mistakenly), here the Eastern Box Turtle referred to
as a terrapin. Terrapins are web-footed turtles that thrive in
freshwater environments. One common in the U.S. is the diamond-backed
terrapin, which does indeed resemble the Eastern Box Turtle. Box turtles
are dry-land inhabitants with a hinged lower shell that closes tightly
when the turtle is disturbed.
In Kentucky, there are 15 known
species of turtles, including the Eastern Box Turtle, pictured at
the top of this page.
Amphibians: Salamanders
According to the Kentucky Department of
Fish and Wildlife, there are 33 known
species of salamanders in the state. Newts and mudpuppies, (or
waterdogs, as they are called in Kentucky), are salamanders.
Salamanders must have dampness and moisture to survive and are likely
to be found near a water source.
Amphibians: Frogs and Toads
True frogs have smooth skins and long legs for leaping. Their close
relatives, the toads, have warty rough skins and shorter hind legs for
hopping. Both are found on land and in water. Toads, however, can
survive far from a water source.
The Bullfrog, found throughout Kentucky is our largest true frog in
the United States.
Found around ponds in the Southeast, but as of yet not recorded in
Kentucky, the smallest frog in the United States is the Little Grass
Frog, which is commonly mistaken for a young frog of another species. At
maturity, the tiny creature is generally less than one inch long.

Smaller frogs found here in the Bluegrass State include the Spring Peeper, (pictured at left),
which is seldom seen and often heard from a distance in the
springtime, as its name implies. Some folks say a chorus of Spring
Peepers sounds like sleigh bells. The groups will gather near
standing water in covered areas. The species is widespread in the
central and eastern United States.
Other small frogs common in Kentucky are our
treefrogs, which have adhesive pads on their toes for clinging and
climbing and can leap great distances in relation to their body
size. Treefrogs are known to change their colors and patterns to
blend in with their surroundings.
Toads are distinguished from frogs by their rough
skin. You will not get warts from touching a toad. However, their
skin can secrete an irritant if handled which should be washed off
immediately. |

A familiar toad found widely across our state is the American Toad.
This slow hopping creature is found in a multitude of environments and
is much treasured by gardeners for their voracious appetites for insects
and worms.
The Western Kentucky University Center for Biodiversity Studies
maintains an excellent web site, "Frogs and Toads of
Kentucky", which offers photographs, a range map and audio clips of
the calls of Kentucky's frogs and toads.
FUN FACT: A scientist who studies reptiles and amphibians is
called a herpetologist.
