About Turtles
Turtles are reptiles of
the order Testudines and have bony or
cartilaginous shells that protect their torso. The
shells are actually modified backbones and ribs that
have evolved into interlocking plates. The upper shell
of the turtle is called the carapace. The lower
shell is called the plastron. The sides of the
shells are joined by bony structures called bridges.
The carapace is covered in a rough layer of modified
skin made of keratin and is often patterned in horny
scales called scutes. Keratin is a hard protein
responsible for many animals' mineral-like structures (scales, nails, beaks, talons, feathers and
porcupine quills). Many turtles can retract their legs
and head into the shell for further protection. Several
species, called Box and Semi-box turtles, have hinges on the
sides that allow them to close their shells almost
completely.
Not all turtles have hard
shells, however. Soft-shelled turtles, like the Eastern
Spiny Soft-shell, have a leathery and pliable shell
made mostly of skin and cartilage. These aquatic species
lack the protection that comes with a full bony shell,
but make up for it with a lower profile and better
maneuverability in water.
Turtles come in a variety
of shapes, sizes and colors. We have no native
tortoises (land turtles) in New York, although a
variety of sea turtles can be found off of Long
Island. The turtles in New York are primarily
terrapins, having close ties to fresh or brackish
water, but can and may traverse solid ground.

Turtles in New York |
|
Unfortunately, many of New York's turtle
populations seem to be in decline. Loss of habitat and
pollution have put a lot of stress on native turtle
populations. Invasive and aggressive species, like the
Red-eared Slider, which was most likely released into the
wild from a pet collection, have put additional pressures on
these sensitive animals. We have three species that are
categorized as "Special Concern," and one listed as
"Threatened" by the state. The Bog Turtle, with its stringent
habitat requirements, is Endangered in NY State and on the
list of Federally Threatened animals.
There are some turtles that are well
established in the waters and wetlands of our state. Most
turtle encounters are going to be with either Painted
Turtles or the (much larger and certainly more aggressive)
Snapper. Both species can be found throughout the state. |

|
|
AKA:
Semi-box turtle.
Identifying characteristics: An oblong, dome-shelled
turtle, often identified by its bright yellow throat and
chin; dark grey/black top shell (carapace) with yellow/cream speckles.
The yellow bottom shell (plastron) has a symmetrical
pattern of dark blotches. Adults may have a completely black
plastron. The skin is dark and may have light speckles. They
are similar
in appearance to box turtles, but have a larger tail.
The hinged plastron allows it to close the anterior opening of
its shell for protection, but not the posterior. The Box Turtle can
completely close its shell.
Size: Average shell length of 7-9 inches.
Habitat: Shallow ponds with plenty of vegetation;
marshes; swamps and lake inlets. They prefer shallow water
and muddy bottoms.
Food: Carnivorous. Primarily snails,
insects, crayfish and small vertebrates.
Temperament: Docile.
Other Info.: Tolerant of cold temperatures, but
not heat, which is why they are generally distributed in
northern states. |
|
Distribution

(Distribution zones are estimates based on
reported sightings).
Scattered across the finger lakes
and eastern NY
Status:
Threatened in NY due to
diminishing habitat. Threatened in many other states.

Bog Turtle
Clemmys muhlenbergii

Click images for enlargements and
license information
|
|
AKA:
Muhlenberg turtle
Identifying characteristics: A very small turtle with a
characteristic bright orange or yellow blotch on each side
of its neck. The skin is dark and the top shell (carapace) is
somewhat rectangular (looking top down). Some aged specimens
may have smooth shells from burrowing in the silt. The shell is
domed, but not very high.
Size: Average shell length 3-3.5 inches.
Habitat: Wetland bogs with plenty of moss or silt
substrate, wet fields. Near clean water sources and with
plenty of sunlight for basking. High humidity and abundant
plants, but little tree cover. Since these habitats
are usually successional and eventually develop trees and
shrubs, bog turtles are ever-threatened while these ideal
habitats are both naturally and artificially changed.
Food: Omnivorous. Seeds, berries, insects, slugs,
snails, earthworms, frogs, snakes.
Temperament: Elusive, wary.
Other Info.: Their small (1 inch) young are easy
targets for predators. Very sensitive to environment
quality. Considered the smallest turtles species in the US. |

|
|
AKA:
Northern Map Turtle
Identifying characteristics: A
low-profile, dome-shelled
turtle is named by its distinctive top shell (carapace) that
has a pattern of yellow lines that resemble erratic river
lines on a map. These lines may fade with age. The shell color
ranges from brown to olive to dark grey. The carapace has a
shallow dorsal keel and a moderately serrated back edge. The
bottom shell (plastron) is most often yellow. Its skin is a
dark olive with yellow, cream or orange striping. Small
light spot located behind each eye.
Size: Average male shell length of 4-6 inches.
Females are larger: 6-10 inches.
Habitat: Wetland habitats with plenty of
vegetation, slow current and soft bottoms such as some
rivers and large creeks, reservoirs, large lakes.
Food: Omnivorous. Snails, insects and larvae, clams,
crayfish and aquatic plants.
Temperament: Elusive, wary.
Other Info.: The majority of this turtle's time
is spent under water. Although it may be found basking in groups
on logs early in the morning. They are diurnal, active both day and night.
Females have broader heads and jaws more adapted for
cracking mollusk and crayfish shells. |

|
|
AKA:
Stinkpot
Identifying characteristics: A generally small turtle
with a highly-domed and smooth oval top shell (carapace), usually black
or brown in color. The carapace may have a distinctive keel, which
wears with age. The skin is dark olive and there are 2
yellow lines that run from the snout to the neck; one line
above the eyes, and the other below the eyes. Their
heads are triangular with a pointed snout and sharp beak.
The legs are short and the neck is long. The tails of males
are usually longer than females. Juveniles may have a
rough shell.
Size: Average shell length of 3.5-4.5 inches.
Habitat: Mostly aquatic, bottom-dweller.
Shallow, well vegetated areas of lakes, ponds,
slow-moving rivers and creeks with soft bottoms.
Food: Carnivorous. Primarily crayfish, mollusks,
insects and small fish.
Temperament: Elusive, wary, but aggressive if
cornered.
Other Info.: Release a foul odor when
threatened.
Will bask on logs and trees over or close to water, offering
them a quick escape. A very common pet species. Rarely seen
out of water. |

Common Snapping Turtle
Chelydra s. serpentina

Click images for enlargements and
license information
|
|
AKA:
Snapper, Snake neck
Identifying characteristics: A large turtle with a
massive head, long and highly mobile neck and powerful
beak-like jaws. The top shell (carapace) comes in various
shades of brown with pronounced ridges (that lessen with
age) and a serrated back edge. Their tails are long and
spiked. Snappers appear like they have outgrown their shell with
their robust body structure. Their skin is rough and
bumpy.
Size: Average shell length of 8-14 inches. 10-35 lbs.
Habitat: Aquatic. Shallow ponds lakes and slow-moving
rivers/canals with muddy bottoms and plenty of vegetation.
They will travel on land, often across roads, to reach a new
habitat or to lay eggs.
Food: Omnivorous. Fish, carrion, invertebrates,
aquatic plants, small birds and mammals.
Temperament: Aggressive and dangerous.
Other Info.: Since they cannot retract their
head and feet fully into the shell, they use aggressive
displays when confronted. Their bite is quick and strong,
often injuring people, sometimes taking off a finger or toe.
Some snappers can reach their neck halfway around their
shell, making them risky to handle. Picking them up by
the tail will most often injure them. It's best to leave
them alone. |

|
|
AKA:
Semi-box turtle.
Identifying characteristics: This high dome-shelled
turtle is often identified by its completely hinged
shell, which can close completely
hiding its soft parts from danger. Its shell is usually brown/olive/black
with brightly-colored patterns of lines, spots and blotches.
Skin color is variable and may share the variable colored
patterns of the shell. Younger turtles tend to have brighter
colors. Their toes are only slightly webbed.
Size: Average shell length of 7-9 inches.
Habitat: Forested areas, damp meadows and fields and
sometimes marshes and bogs. During hot and dry weather,
it will burrow into damp muddy areas. They can often be found
under forest debris.
Food: Omnivorous. Primarily snails, slugs, insects,
fruits, mushrooms (some of which are toxic to humans) and
small amphibians. Their diets are opportunistic.
Temperament: Docile.
Other Info.: Often kept as pets. Like most
turtles, males are often identified by their concave bottom
shell (plastron). They are diurnal, active day and night. |

elongate, oval shell, which comes in brown or black with
some red/orange markings. The bottom shell (plastron) is
red/orange, often with black blotches. The skin is black with
yellow/cream stripes. The eyeballs appear to also have a stripe
running through them, probably as an adaptation to help them hide.
Size: Average shell length of 10-14 inches.
Habitat: Aquatic. Relatively deep water,
rivers, creeks, marshes, ponds or lakes with soft bottoms and
plenty of vegetation.
Food: Omnivorous as juveniles, herbivorous as adults.

Eastern
Spiny Softshell
Apalone s. spinifera

Click images for enlargements and
license information
|
|
AKA: Soft-shell
Identifying characteristics: This turtle is an easy one
to identify. It has a very flat, round and soft skin shell
that gets more bony towards the center.
This turtle looks like a brownish/green pancake with head and legs.
The shell lacks the bony scutes (scales) that other turtles
have and instead is made of tough skin. The shell may have
some small spines in the front. Males have a light
green/olive shell with small black spots. Females have a
dark green shell and large blotches.
The legs and feet have a pattern of dark lines and speckles. The snout is large, pointed and is used as a
snorkel. It may have two lines running down the head from
the snout past the eyes, both on the top and bottom. The
feet are highly webbed.
Size: Average shell length of 14 inches. Some
reaching over 25 inches. Females are generally twice the
size of males.
Habitat: Aquatic. Ponds,
marshes, rivers and lakes with muddy bottoms and minimal
vegetation. They require elevated sandy nesting areas near shore.
Food: Carnivorous. Insects and crayfish. They use both foraging and
ambush techniques to capture prey.
Temperament: Wary, elusive.
Other Info.: Diurnal: active both day and
night. Often found basking on logs close to water. When
disturbed, will dive under and bury themselves in the mud or
sand. Well-adapted for staying under water for a long time,
as they can adsorb oxygen through their skin. Very fast,
agile swimmers. |

|
|
Identifying characteristics:
A mid-sized turtle with a relatively low-domed top shell
(carapace) that comes in olive to black with yellow/red
accents. These accents may diminish with age. The bottom
shell (plastron) is a bright orange/red and has a beautiful
symmetrical design that look like it was painted. This pattern may also fade with age. Yellow and red stripes
on the neck.
Size: Average shell length of 7-9 inches.
Habitat: Most aquatic habitats, but prefers shallow,
calm areas of lakes, ponds and marshes with plenty of
vegetation.
Food: Omnivorous. Aquatic and terrestrial plants, slugs,
snails, insects, small fish, carrion, algae.
Temperament: Docile, wary.
Other Info.: One of the most common turtles in
N. America ranging across the entire continent. Will usually bask in
groups on logs and along the shore. |

Red-eared Slider
Trachemys scripta elegans

Click images for enlargements and
license information
|
|
AKA:
Red-eared Terrapin, Elegant Terrapin
Identifying characteristics: Easily identified by the
broad red stripe running from the eye down the head towards the shell,
although this may fade in older specimens. Sometimes they
may also have a red spot on top of their head. The top shell
(carapace) of juveniles starts out as a bright green with
yellow and darker green patterns of wavy lines. As they age,
the carapace becomes more yellow. As time goes on, the shells
take on a more dull and
uniform shade of olive. Elderly specimens may have brown to
black shells with no patterns. They are easily confused with
the Painted Turtle.
Size: Average shell length of 5-6 inches for males
and 8 inches for females.
Habitat: Quiet aquatic habitat with abundant
vegetation. Ponds, lakes, backwaters.
Food: Omnivorous. Aquatic and terrestrial plants,
slugs, snails, insects, small fish, young birds and eggs.
Prefers dragonfly larvae.
Temperament: Docile, wary.
Other Info.: Intolerant of colder temperature,
which limits their range and survival in the north. Often
found basking on rocks, logs, grass and banks. They are very
popular pets and have been introduced as invasive species in
many parts of the world due to the pet trade. |
|
Distribution

(Distribution zones are estimates based on
reported sightings).
Some populations scattered throughout the
state. Populations are the result of artificial introduction.
Status:

Spotted Turtle
Clemmys guttata

Click images for enlargements and
license information
|
|
Identifying characteristics:
Aptly named for its spotted shell, this small turtle has a
dark brown or black top shell (carapace) with a pattern of
scattered round yellow spots. Its bottom shell
(plastron), is either yellow or faint orange with a black
blotch on each bony plate (scute). Shell markings may fade
with age. Its skin is black and has the same yellow spots as
the shell.
Size: Average shell length of 4.5 inches.
Habitat: Aquatic, preferring shallow waters with
muddy bottoms and abundant vegetation. They will travel on
land to bask, nest or search for a new habitat and will
often be found hiding under leaf debris.
Food: Omnivorous. Aquatic and terrestrial plants, slugs,
snails, insects, small fish, crayfish, carrion, algae.
Temperament: Docile.
Other Info.: Tolerant of cold temperatures, but
not heat, which is why they are generally distributed in
northern states. A common pet. |

Wood Turtle
Clemmys insculpta

Click images for enlargements and
license information
|
|
Identifying characteristics:
An oblong, dome-shelled turtle with a brown/grey top shell
(carapace) with a small central keel. The color of the
shell and its fine grain ring pattern looks very similar to wood. The bottom shell (plastron) is
yellow with a black blotch on each bony plate (scute). The
head is generally black, often with small colored spots,
while the limbs may be a lighter color. The neck and
portions of the limbs close to the shell are often a yellow
or orange.
Size: Average shell length of 6-10 inches.
Habitat: Semi-aquatic. Although they prefer moving water,
such as rocky or sandy streams and rivers, they can often be found
away from water in bushy and wooded areas. They need
moist sand for nesting.
Food: Omnivorous. Herbaceous and woody plants, fruits,
fungi, algae, slugs, snails, insects, earthworms, carrion.
Feeds both in and out of water.
Temperament: Docile.
Other Info.: Diurnal (active both day and
night). An odd behavior has been observed in some
populations of wood turtle: by stomping their feet or shell
on the ground, they encourage earthworms to surface, and then
they feast on them. |
|
Distribution

(Distribution zones are estimates based on
reported sightings).
Well distributed across the state and
adjacent states.
Status:
None, but numbers are diminishing due to loss of habitat
and "removal" by humans.
