Snapping Turtle

There are 48 species of turtles in the United
States and Canada. World wide there are 260 species, of
these only seven are marine. Turtles are found in a variety
of habitats such as on land, in the ocean, in freshwater, and in
temperate and tropical climates. They are found on every continent
except Antarctica. The turtle is the oldest living reptile
dating back over 200 million years, well before the dinosaurs.
Turtles are also referred to as tortoises and
terrapins. Tortoises are large terrestrial turtles and
terrapins are aquatic, edible, and hard shelled turtles. All
turtles have dry scaly skin and are cold blooded, which means
their blood is regulated by the environment. This is a main
reason turtles are often seen basking in the sun.
All turtles lay hard-shelled eggs. Sea
turtles will lay more than a hundred and some terrestrial species
will lay as few as two. Females always lay eggs on land.
They dig a hole with their tail, and deposit the eggs, cover the
hole with earth, and leave. The eggs hatch, depending on the
species, anywhere from six weeks to seven months. The baby
turtles must dig their way out of the holes, in addition, aquatic
species then must also find water.
Turtles are characterized by a shell on their
back, called a carapace, which encloses the turtles’ body.
The turtles’ ribs are fused to the carapace, ensuring the
permanence of the shell. The underside of the shell is
called the plastron. From the shell, the head, legs, and
tail can protrude. Turtles do not have teeth, they have
horny beaks. The beaks are shaped differently according to
the diet of the turtle. For example, a carnivorous turtle
will have a beak that is more hooked and curved as opposed to a
turtle that eats more plants or mollusks, their beak will be more
flat and broad.

The Snapping Turtle is a large turtle that grows to be 20-46
cm, and has an average weight of 10-35 pounds. This species
has a large head and a narrow tail that is jagged on top. It
has a small black to light brown colored carapace that usually has
algae growing on it. The upper jaw is hooked and the toes
have long claws on them. Between the months of May to June
the females’ lays between 7-55 eggs in tail dug nests.
This species is generally found in freshwater and sometimes
brackish water with muddy substrate. The snapping turtle
hibernates from around October thru April. To capture food,
this species buries itself in mud and waits for prey which
generally includes frogs, crawfish, young waterfowl, aquatic
vegetation and insects
Snapping
turtles are fascinating animals, and captives are relatively hardy
with proper care. However, the large size, long life, and
aggressive nature of this species deserve serious consideration.
Size: The carapace length of common snappers frequently exceeds
one foot with a record length of 18 ½ inches (Pritchard). The
average adult weight is thirty pounds, but 40-60 pounders are not
uncommon (Dillon). Snappers grow fast! That 2-inch baby you
brought home to a ten-gallon aquarium can be 4 inches in one year
and 8 inches in two. It will eventually require either a pond
setting or a gigantic aquarium (more than a hundred gallons).
Messiness: Snappers are both voracious eaters and highly aquatic.
This combination equals frequent water changes! The best
filtration cannot keep up with smelly snapper wastes. You must be
prepared to do complete water changes at least once a week if not
more often.
Aesthetics: If you want a beautiful tank landscaped with plants,
you do not want a snapper! Your little charge will rearrange the
tank to his or her liking, uprooting plants and pushing everything
including rocks and the filter into new positions. Snapper tanks
must be kept simple. Expense: The initial investment for any
turtle amounts to several hundred dollars for a tank, filter,
heater, UVB lighting, and a basking light. Larger tanks and
equipment for your eventual "behemoth" will cost much
more.

Aggressiveness:
Yes, it's true that snappers are more docile in their aquatic
environment than on land. They sit quietly and give you long
soulful stares - hungry stares!!! Snappers will eat anything
including your fingers! They charge their food, and your digits
can easily be mistaken for worms in a feeding frenzy. You cannot
mix them with other turtles including other snappers. Even small
snappers can cause serious harm to each other. They will also
attempt to eat all the other inhabitants of your prized outdoor
pond, including ducks and ornamental fish.
Longevity: The life span of the common snapper has been estimated
at 30-40 years (Dillon). Are you prepared to commit one third to
one half of your life to your friend? What if you move? If you are
thinking you can just release your turtle in a few years, remember
that most states still permit the harvesting of snappers. You
wouldn't want your buddy to end up in a can of soup! And zoos are
"full up" with unwanted snappers and other reptiles.
Most are no longer accepting ex-pets.
Please think twice and thrice before acquiring a snapper. It is
cruel to take home that cute baby on an impulse if you cannot
provide permanent quarters. Snappers are living, breathing beings
and not playthings. Please award them the compassion they deserve.

BASIC
CARE FOR SNAPPING TURTLES
You
have decided to take the plunge! I hope the following care sheet
will get you started:
Tank
Setups
Glass Aquariums: You may temporarily keep your snapper in a
water-filled plastic container, but you will eventually need a
glass aquarium for your indoor accommodations. Some snapping
turtles kept in close confinement develop sores on their bottom
shells from constant abrasion with plastic, rocks, or other rough
surfaces. The affected areas will initially look more orange than
the surrounding color and will progress to pinhead-sized holes in
the shell. Sores that do not heal with corrective husbandry should
be seen by a vet.
In addition, glass enclosures allow your friend to look out. Your
baby snapper that wants to hide will soon turn into an
intelligent, inquisitive juvenile that enjoys "watching the
world go by." If you house other turtles in aquariums, try
placing one end of your snapper's aquarium end-to-end with another
turtle's tank, but provide a place for retreat and privacy at the
other end.
Remember that your snapper is going to grow fast! A one-inch baby
will become a 7-inch juvenile in two years with the proper diet.
Buy the largest tank that you can presently afford. A rule of
thumb is to provide ten gallons of water for each one inch of
snapper shell length. Your ten-inch snapper is going to require a
one hundred gallon tank. The tank should be long and wide rather
than tall to provide more swimming area. Since a snapper will stay
at the bottom of the tank most of the time, a tank with shorter
walls will facilitate rays from your lighting source reaching your
turtle. A 30 gallon "breeder' tank (12" high x 36"
long x 18" wide) makes a good first choice for a small
snapper.
Substrate/Covers: The author and some vets recommend a completely
bare-bottom tank, at least for beginners. Snappers are messy, and
you will have enough work changing all the water once a week
without also doing gravel washes. You will not need gravel to
anchor plants or decorations, because your snapper will uproot,
rearrange, and eat everything in the tank, including the gravel!
Do not place plastic plants, large marbles, or other decorative
items in your snapper's tank if you do not want a snapper with a
life-threatening intestinal impaction! Snappers in the wild bury
themselves in mud at the bottom of marshes and lakes. This
environment may be simulated in an outside pond, but the author
hasn't experimented with soft substrates in indoor setups.
An older snapper may eventually be able to crawl out of the tank.
You may need to buy a hood or screen cover or construct your own.
Hiding/Basking: Your snapper, especially a baby, should be
provided with a hiding place at one end of the aquarium. The
author recommends, however, that you do not build a cave with
rocks or pile up rocks in the tank. Your snapper is powerful and
may bring the whole structure down, pinning your turtle
underneath. A good hiding place can be fashioned from a small,
plastic kitty litter pan. Cut out one end of the pan, turn it
upside down at the end of the tank, and put a very large rock on
top to hold it in place. Another option the author has used in an
18-inch wide tank is a 17-inch wide Rubbermaid kitchen stool
placed widthwise with a rock on top. The snapper feels secure
under the stool but can still see out.
Wild snappers usually stay submerged at the bottom of water
bodies, but some will bask by either floating at the surface or
"hauling out" onto logs. You can experiment with a
basking spot by wedging a smooth piece of wood between the
aquarium walls and angling it up out of the water. Fasten a clamp
light fixture available at hardware stores to the tank rim with a
60 watt bulb (reptile or incandescent) a foot over the basking
spot.
Water Depth/Temperature: WATER DEPTH IS MOST IMPORTANT! Snappers
spend most of their time resting on the bottom and extending their
long necks up to get breaths just above the water surface as
needed. The depth should be at least a bit deeper than the turtle
is wide to allow for swimming and righting the body if turned
over, but shallow enough to allow for breathing from a resting
position. If your snapper is forced to swim to breathe, it may die
from the energy expenditure. A hatchling should be observed to see
whether or not it can lift its head out to breathe and the setup
changed to include a dry slope if it is having trouble.
Snapping turtles need a slightly cooler range of water
temperatures than that prescribed for some other species. They
will feed eagerly at 68 degrees F or above but become
uncomfortable with water temperatures in excess of 77 degrees F (Highfield).
Submersible glass tube heaters or other electrical appliances that
might easily be broken by snappers should not be used in their
enclosures due to the risk of electrocution. The author heats her
snapper's tank with a combination of warm room temperatures and a
basking lamp. Do not leave a thermometer in your snapper's tank!
Filtration: Buy the strongest filtration system you can afford. A
Duetto 100 submersible filter may work for a hatchling in ten to
twenty gallons of water but will not keep up with wastes as your
snapper grows. Reasonable persons may disagree as to what
constitutes effective filtering. The subject is a paper onto
itself. You must experiment with what works for you, knowing that
the bottom line is keeping the water clean. Large external
canister filters provide strong filtration, but the author's
snapper continually dislodged and bit the tubing. You may be more
creative and find a way around this dilemma. The author presently
has great success using a Fluval 4 submersible filter,
hand-siphoning observable solid wastes with a turkey baster,
feeding her snapper in a separate tub, and one-week water changes.
Effective filtration will depend upon whether you choose to use a
substrate or not, the size of the turtle and its tank, the size of
the filter, the filter media, how you feed your turtle, and other
factors
Lighting: If your snapper does not have access to natural lighting
in an outdoor (pond) setup, you should provide a reasonable
facsimile for the UVB component. Do not place your tank in a
window for several reasons. The water in your tank may overheat
and kill your snapper. The glass in the window and the tank will
filter out the beneficial UVB component of the sunlight. The
sunlight may cause algae to grow in your aquarium.
You can buy a hood that holds UVB tube lights to place over your
tank or you can make one. If a hood you buy contains glass or
plastic strips that protect the tube lights, you will have to
remove the strips which filter out the UVB light. Other options
include hanging a shoplight fixture with the tube lights over your
tank or setting one or more strip light fixtures with the tube
lights on a screen cover. The consensus recently seems to be that
Reptisun 5.0 tube lights made by Zoomed work well. They lose their
effectiveness over time and need to be replaced every 6 months to
1 year.
Ideally, try to expose your snapper to some summer sunshine
outside in a tub. Don't place the tub in direct sunshine, and do
monitor the water temperature. Overheating can kill! Watch your
snapper. They are excellent escape artists. You may wish to put a
screen with a heavy rock on top of the tub.
DIET
Snapping turtles are omnivorous. In the wild, snappers will eat
small mammals, birds, other reptiles including smaller turtles,
amphibians, fish, crayfish, crabs, clams, snails, earthworms,
leeches, insects, carrion, and many kinds of plants like Elodea,
Polygonum, Nuphar, Nymphaeca, and Typha (Ernst and Barbour). In
captivity, snappers will eat just about anything, but you will
want to give them a varied and healthy diet from the following
list:
Aquatic Turtle Foods - Buy the floating turtle pellets like
Reptomin and not fish foods.Turtle pellets make a good staple and
should be offered regularly.
Live Foods - Night crawlers, meal worms, crayfish, crickets, and
minnows are a few choices. You have to be careful, though. Don't
buy night crawlers grown in animal wastes or bait shop minnows
that have been raised in chemically-treated water. Don't get
worms, slugs, or insects from fertilized lawns or roadside
ditches. Goldfish may carry bacteria and snails may have parasites
like flukes that can kill your snapper.
"People" Meats - Never give your snapper fatty or raw
meats. Always cook chicken which can carry salmonella. Feed only
as an occasional treat.Plant Produce - This is a good way to get
some vitamins into your snapper. The author's snapper loves chunks
of microwaved sweet potato and butternut squash which are loaded
with carotenoids, collards with some calcium, and strawberries
with Vitamin C. Float some red-leafed lettuce in your snapper's
tank and watch it disappear. Wash all produce thoroughly before
giving them to your friend.
Supplements - You won't need to give your snapper vitamins if you
are providing a balanced diet, but offering pieces of cuttlebone
as a calcium supplement is recommended. Chip the soft front of the
cuttlebone into the tank and throw away the hard backing. Discard
any uneaten pieces with each water change or sooner if they start
to smell.
Feed your snapper in a separate tub to keep your tank clean
longer. The water temperature in the tub should be about the same
as in the tank or just a bit warmer. Turtles often defecate within
an hour of being fed, so wait awhile before returning the snapper
to its tank. Feed hatchlings once or twice a day. Small bits of
earthworm have often been successful in enticing them to eat. Wave
the worm piece in front of them with a toothpick. Larger snappers
can be fed three times a week. If your snapper appears to be
bulging out of its shell, cut back on its food. If its skin looks
loose and baggy, feed it more. You will find an even keel through
trial and error.
Care Tips
As hatchlings grow, some persons become alarmed when their babies
begin to look "furry." Do not apply medications to your
hatchlings or juvenile snappers! They do not have fungus or algae
growing on them. They grow initially by shedding many, many small
bits of shell and skin. A hatchling's shell feels extremely soft
at first but gradually hardens with a proper diet.
When the shell has hardened up, clean you snapper's shell, top and
bottom, once or twice a month with a very soft toothbrush to help
prevent any fungal growth. Place your snapper in a small tub of
lukewarm water and brush the top shell GENTLY. Make sure to get
into all the grooves and along the edges. Brushing the bottom
shell can be a bit tricky! While still a size that allows for
grasping with one hand, you may be able to hold the snapper upside
down momentarily and get in a few brush strokes. The author's
snapper will usually freeze for at least 30 seconds when held this
way. Check for any light orange or slightly off-color patches and
gently brush over them. If beginning or actual sores are present,
check your aquarium for rough spots and keep that water clean!
Seek advice from a vet for more than the most superficial sores or
for any sore that won't heal.
