What do salamanders and other animals need to survive?
The teacher will read the book The Salamander Room
by Anne Mazer to the students and discuss it with the students.
The teacher will discuss with students some of the interesting
characteristics of the spotted salamander and have them think
about what they would need to do to ensure a salamander would
survive if they were to keep one as a pet. The students will
then discuss what they would need to do to keep a river otter,
an American alligator or a bottle-nosed dolphin as a pet in
the classroom. The students will create a mural on the wall
to show how they would meet the habitat needs of the animal
they have chosen.

BACKGROUND Key Points Detailed Information Animals need food, water,
air, shelter and space to survive. No matter where an animal lives, it must
be able to attain these things. The world is comprised of many different environments
with many varied climates. Because of this, animals develop specialized adaptations
to allow them to get the things they need to survive from a variety of different
environments. Where they get these things is there habitat. The animals found
in the deep ocean are not the animals found in the tropical rainforest or the
desert or the tundra, yet all these share in common the need for food, water,
air, shelter and space. Animals cannot produce their
own energy like plants can, and so they must eat other organisms to get their
food energy. Some animals, such as deer and elk, are herbivores, and eat only
plants. They make use of the energy the plant has produced through photosynthesis.
Some animals, such as eagles and hawks, are carnivores that eat other animals
and get their energy from the organic compounds stored in their prey. Some animals,
such as humans, are omnivores that can eat both plants and animals. Some animals
are scavengers that live off of dead animals, such as turkey vultures, and get
energy from the organic compounds remaining in the animal's dead carcass. Some
animals, such as blue crabs, are opportunistic feeders, meaning they will eat
just about anything they can get their mouths around. All animals depend on
the food they eat to receive the energy and nutrients they need to carry out
their life functions. All living things depend
on water to survive. Water is a major component of all the fluids in the body
as well as the protoplasm of each individual cell. Water is also important as
a solvent for chemicals and nutrients in the body. Water makes up 60 to 90%
of the composition of all living things. For this reason, all animals must find
a way to intake water on a regular basis. All animals must bring oxygen
into their systems in order to convert food energy into usable energy. For this
reason, all animals must utilize some form of respiration. Terrestrial animals,
such as reptiles and mammals can pull oxygen out of the atmosphere. Aquatic
animal such as fish can pull oxygen out of the water. Amphibians can do both.
Because life processes occur twenty-four hours a day and they all require energy,
an animal would soon die without oxygen. Animals also depend on shelter
to survive. Shelter protects an animal both from the elements and from predators,
and thus increases its survival chances. Shelter can take many forms. The shells
of snails and other mollusks, the nests of birds and the burrows and dens of
mammals are just some examples of shelter. Space is necessary too.
If too many animals are competing for the same space, than they are also often
competing for food, water and shelter. Being crowded together makes the animals
more prone to diseases and parasites, which are spread more quickly and easily.
Because an environment can only support a certain number of organisms, removing
predators from an ecosystem can sometimes have negative effects on the animals
the predator preys on. Without the limiting factor of predators, the prey animals
can multiply rapidly causing a loss of space for these animals and leading to
diseased and malnourished animals.
Key Points will give you the main information you should know to teach the
activity.
Detailed Information gives more in-depth background to increase your own
knowledge, in case you want to expand upon the activity or you are asked detailed
questions by students.
An animal's habitat is the place where it can get air, food, water, space and shelter. The animal's adaptations determine where its habitat will be. Because an animal has specific habitat requirements, if you take the animal away from its habitat, or if you bulldoze the habitat away from the animal, the animal will not survive. This is why a habitat that is suitable for one animal, such as a house for a human, may not be suitable for another animal, such as a house for a salamander. The house cannot meet the salamander's habitat needs.
Featured
Species
Spotted Salamander (Ambystoma maculatum)
The spotted salamander is the state amphibian of South Carolina. This 6 to
10 inch salamander is found near shallow pools in deciduous forests in eastern
North America from Louisiana to Canada as well as throughout South Carolina.
In South Carolina it is most common in the Piedmont and Mountain regions.
These salamanders avoid areas prone to flooding or pools populated with fish.
They spend a good deal of their time in burrows underground or under trees
and so are difficult to find.
Spotted salamanders prey on insects, worms, slugs and other small invertebrates. They can most easily be found on a rainy night on the forest floor looking for food. In the wild, they can live over 30 years.
Though they spend most of their adult life on land, they lay their eggs in water and spend their larval stages in water. Therefore, spotted salamanders tend to stay near aquatic habitats. When it warms in spring, the female will move to a shallow pool, lay 200-250 eggs in a mass on submerged sticks. The eggs will hatch within two months. The larval salamanders will remain in the pool for another two months, maturing and developing until they look like adult salamanders. They then move on land to begin the terrestrial life of an adult spotted salamander.
River Otter (Lutra canadensis)
The
largest mammal predator in the mountain stream, river otters are found throughout
North America except for the extreme northern portion of Alaska and the Southwest
desert and arid Plains states. Locally common in South Carolina, it ranges across
the state in virtually all freshwater and estuarine aquatic habitats. A member
of the weasel family, the otter has short legs with webbed toes, a broad tail,
and an elongated body. An adult otter will grow from three-and-half to four feet
in length and weigh from ten to twenty-five pounds. Social animals, otters travel
within a home range of 15 square miles in family units of four to five individuals.
Uniquely adapted to its aquatic environment, the otter has webbed toes, a water-repellant coat, and the ability to close its ears and nostrils while diving. The otter also has long whiskers that help it to detect prey underwater. These adaptations allow the animal to exist chiefly on a diet of fish, which they catch with their superior underwater swimming skills. Otters are also known to eat frogs, turtles, snakes, crayfish, and an occasional bird.
Beavers are very important to otters. If beavers frequent a particular area, there is a good chance that otters will also be found there. The ponds created by beaver dams are prime habitat for the otter. Otters often use the abandoned dens of beavers as sleeping quarters. If a beaver den is not available, they also may be found in hollow trees or between rocks or roots, building nests out of sticks, leaves and grass.
Otters are active and curious. They spend much of their time playing with each other and exploring their environment. While other animals may play to practice hunting and survival skills, otters often play for pure enjoyment, a rare trait in animals and usually a sign of higher intelligence.
Mating takes place in the fall after rival males battle for a mate. After a gestation period of up to 270 days, the female otter gives birth to one to three young, called kits, in a den with an underwater entrance constructed beneath the bank of a stream, river or lake. The mother otter defends her kits fiercely and they remain with her as a family unit for over a year.
The otter has few natural enemies other than man, who trap it for its rich, thick pelt, and who also have lowered populations through habitat destruction and roadkill. Look for otters in larger streams or rivers where food is abundant and the water is unpolluted and quiet. The best time to look is early morning or evening.
American Alligator
(Alligator mississippiensis)
American
alligators, the largest land reptile in the United States, are found throughout
the Coastal Plain of South Carolina. These crocodilians grow from 8 to 12 feet
in length, though individuals up to 18 feet in length have been found. Despite
their size and their reputation, they are generally not a threat to people.
In a quarter century, there have been only six documented alligator attacks
on people in South Carolina and none were fatal. An alligator's diet consists
of invertebrates, fish, birds and small mammals. Generally if a person is attacked,
it is because the alligator was protecting itself or its young and not because
it was seeking a meal. Like any wild animal, though, it is a good idea to keep
a respectful distance from an alligator, and not to engage in any activity the
animal finds threatening such as approaching it.
Alligators are found in freshwater swamps, marshes, impoundments, lakes, ponds and the backwaters of large rivers. Alligators are cold-blooded aquatic animals that depend on the sun for warmth and freshwater aquatic habitats for food. For this reason, they are found only in the Southeastern United States, where the climate is warm and water is plentiful.
Adult alligators feed on fish, turtles, aquatic birds, water snakes and small mammals. Many alligators also feed on carrion. Alligators are carnivores, but they are also opportunistic feeders, and will not turn down an easy meal.
Alligators are often found in the day basking in the sun on the shore of some body of water. Unable to maintain a constant body temperature, alligators depend on external sources to raise or lower their body temperature. Absorbing sunlight warms the alligator and prepares it for evening hunting. If it becomes too warm, it will move to the water to cool off. In the winter when temperatures drop, alligators go into a semi-dormant state, and generally do not become active again until March.
Female alligators are very protective mothers. In June the female builds a mound made of dirt and vegetation about seven feet in diameter and one to two feet in height. In the middle of this mound she digs a hole and lays 15 to 80 eggs. This nest acts as an incubator that keeps temperatures for the eggs in the upper eighties. During this whole time, the mother watches the nest with a protective eye and keeps hungry predators away. When the eggs begin hatching in September, the mother helps the young by digging them out of the nest and even gently carrying some of the young in her jaws to the water. It is amazing that jaws capable of exerting 3,500 pounds of pressure per square inch on a prey item can be used for such delicate actions. For up to a year the mother will stay with the young to protect them from predators. During this time, the young alligators feed on insects, crayfish and frogs.
Atlantic Bottlenose Dolphin ( Tursiops truncatus)
The
Atlantic bottlenose dolphin, commonly misidentified on the South Carolina coast
as a porpoise, occurs from Cape Cod south through the Caribbean and Gulf of Mexico
to northern South America. Common along the entire southeastern coast, it frequently
ventures up tidal creeks and rivers into virtually freshwater. The bottlenose
dolphin grows to twelve feet in length.
Dolphins typically breed in the spring, and after a gestation period of twelve months, one calf is born. At birth the three-foot long dolphin calf weighs approximately 25 pounds. The calf will stay with its mother and nurse for 12 to 18 months before fending for itself. Dolphins live for 25 to 40 years on a diet comprised primarily of fish, squid, and shrimp. The bottlenose dolphin requires about 10% of its body weight in food daily.
Dolphins use echolocation to help them to pinpoint the location of prey. The underwater use of sound to locate food is similar to the terrestrial echolocation used by bats. Dolphins occasionally use complex herding formations to capture fish. In shallow tidal creeks, a pod of dolphins sometimes herds fish towards land. When the fish are cornered, the dolphins rush in and knock the fish onto a sand bar or mud bank with its powerful tail. The dolphin then pulls itself out of the water onto the bank and retrieves its stranded prey.
To prevent sharks from invading their territory, dolphins are known to attack the sharks by ramming the shark in the gills with their rostrum (snout) in an effort to force the shark to leave the area. On occasion dolphins have been observed to surround a shark and take turns either ramming the shark or tossing it into the air. It is unknown if this behavior is a serious attempt to injure the shark or simply a playful game.
Dolphins also display cooperative behavior. Healthy dolphins will come to the aid of another sick or weak dolphin. The two stronger dolphins will flank the sick animal and guide it to the surface by supporting it under a pectoral fin. On rare occasions, the bottlenose dolphin has helped humans in distress in the water. This usually involves a drowning person that the dolphin pushed to the safety of shallow water.
PROCEDURES Materials
Procedure
Follow-up questions
ASSESSMENT Have a variety of books
available to the students that tell about different animals and their habitats.
Have the students look through the books to choose an animal that they would
like to have come live with them. Students should then determine how they would
have to change their room to meet the needs of the animal they have chosen.
They should make a drawing and/or a written description of what they would do.
In their drawings and/or descriptions of how they would alter their rooms to
meet the needs of their chosen animal, students will provide food, water, shelter
and space to their chosen animal. For example, if the student chose a river
otter, their description and/or picture might include: water to swim in and
drink, fish in the water to eat, a hollow log to sleep in and enough space to
move around in. Space will have to be a judgment call. If the student opens
up their rooms to the outside or expands it in some way, this would be acceptable.

Science
Students will look at pictures
of different animals to determine which look similar and which
look different. For example, they would look at pictures of
an otter, a beaver, a raccoon and a snake and decide which
one does not belong with the others (the snake does not belong
because it is not a mammal and does not have fur like the
others). Other sets: An alligator, a lizard, a snake and a
dolphin (the dolphin does not belong because it does not have
scaly skin like the others). A salamander, a toad, a frog
and an egret (the egret does not belong because it is a bird
and has feathers, unlike the other animals). A pelican, a
woodpecker, a cardinal and an opossum (the opossum does not
belong because it is not a bird). Students will learn about
mammals, reptiles, amphibians and birds.
Have students think about their habitat, the local community.
Have students think about and discuss where they can get air,
food, water, shelter and space in their community.

Animals
Going out in a natural area is not always a guarantee of seeing animals,
but you can always see their habitats. Certain places in South Carolina, though,
are well known for their abundance of birds. Birds are very useful for seeing
an animal in its habitat. Students can observe and discuss differences in body
size and shape, as well as beaks, wings and feet, and consider how they are
used to find food. Below are some sites where birds are plentiful.
This state park, located just south of Myrtle Beach,
is known as one of the best bird watching sites along the
east coast. With its marshes, maritime forest and beach,
the park offers education programs that will foster understanding
of the interdependence of natural communities. For more
information call (843) 838-2011 or click on: www.southcarolinaparks.com/.
Located on the shore of Lake Marion near Summerton,
this refuge contains a diversity of habitats, and songbirds,
wading birds, raptors and migrating waterfowl can all be
seen here. Besides preserving natural habitats, the reserve
also contains historical landmarks such as the Santee Indian
Mound. An interpretive visitor center is open all year round
from Tuesday through Sunday. For information on visiting
call (803) 478-2217 or e-mail r4rwl_sc.snt@mail.fws.gov.
Located south of Charleston on the coast, more than
half of this refuge is salt marsh, and it is a good place
to see the wading birds that are common to this habitat.
At the right time of year, migrating songbirds are also
common here. Though the refuge does not offer any structured
programs, school groups are welcome to visit the refuge
and use it for self-guided exploration. The refuge is open
seven days a week from dawn to dusk. For information on
visiting call (843) 889-3084 or e-mail r4rw_sc.abs@fws.gov.
Located on the southernmost point of South Carolina,
this refuge is used by organisms not found anywhere else
in the state. Almost 300 species of birds can be found here.
The refuge is open to the public seven days a week, and
if arrangements are made in advance, volunteers can lead
school groups on guided tours. For more information call
(912) 652-4415.
One of the best places to actually see animals feeding or searching for
food is in a salt marsh. Many species (wading birds, fiddler crabs, oysters,
periwinkle snails) may be easily observed. Below are listed some of the
sites where salt marshes are accessible to students.
Located near Awendaw, this refuge preserves 64,000 acres
of marshes, open water and barrier island. The Sewee Visitor
and Environmental Education Center is an interpretive center
for the public and school groups that is open Tuesday through
Sunday. A boat tour to undeveloped Bulls Island is also
available that allows a close up view of the marsh. For
more information on Cape Romain National Wildlife Refuge
call (843) 928-3368. For information on the boat trip to
Bulls Island call (843) 881-4582.
Located on Charleston Harbor, this division of the South
Carolina Department of Natural Resources offers interpretive
programs that take students directly into a salt marsh.
For information on making arrangements for a program call
(843) 762-5437.
This reserve, located between Edisto Beach and Hunting
Island, contains 12,000 acres of tidal marshes and estuarine
waters. The area is rich in wildlife: fish, crustaceans,
birds and even mammals can all be found here. Boat tours
are available through this area for high school and college
students. For more information call (843) 762-5032.
