Natural History
There are 2,500 different species of amphibians. The oldest
amphibian fossil was found 360 million years ago. Ecology
is the study of the species and its environment, and I am studying the
spring salamander and its environment.
The spring salamander is an amphibian, not a mammal. One of
the reasons for that is because it's not warm blooded and it lays eggs.
The spring salamander is a consumer, which means that it eats other
organisms for food. The spring salamander evolved from a
lobe-finned fish. A
spring salamander is a lungless salamander. The spring salamander is
one of the species
of concern listed in Maine, and it is on the way to being
on the threatened species
list. There are nine families and over three hundred and fifty
different species
of salamander. Most of these species live in North America.
Reproducing in most families is internal, which means that breeding
usually is within the same species. The spring salamander that lays
eggs is the female. To reproduce, most salamanders have to return to
water, but some of them can lay eggs in moist fertile ground. An
interesting fact about the spring salamander is that the species in
Latin means “fire lizard.” The reason they would call it that is
because a long time ago they would put a wet log on the fire and the
salamander would crawl out.
The stages that the spring salamander has to go through are egg, larva, juvenile, and the adult stage. In the larva stage they have gills, no eyelids, a long tail, and fins.
The size of the prey is determined by the size of the salamander.
The
spring salamander usually lives for five years. The spring salamander
usually lives near water.
Habitat
A habitat is where an animal lives. The ecosystem helps
the salamander a lot. It gives it its food and its habitat .The
spring salamander is usually found somewhere where it is pretty cool
and wet. This is a called endemic which means that it is
native to
one place.
If you were hiking beside a small spring and you were looking
closely, you might find some spring salamanders. If you wanted to find
one you
might do these things: look under rocks, look under logs, and
around
fresh running springs in mountains. Other places where these
salamanders
would live are boggy areas, and in cool dark caves. In order for a
spring
salamander to reproduce, it has to come back to water, unlike some of
the
other species who can lay eggs in the ground. The ground soil
must
be moist for them to reproduce.
Present Status
Its present status is species of concern in
the State of Maine.
Physical Description
The spring salamander is a vertebrate. It is grouped into
the Phylum Chordata. Spring salamanders are salmon pink, or
brownish orange. Most people would think that this animal was a reptile but its
not--it's
an amphibian.
Sometimes
they also have black dots on their back. The adult salamander can grow
up to seven or even eight inches long. The spring salamander is one of
the first amphibians to emerge from water in the spring. The spring
salamander
can lay between forty and one hundred eggs.
The spring salamander looks more like a lizard than a frog or toad.
It
has very smooth skin, with no scales and no claws on its feet. The
spring
salamander has a tail and its legs grow from the side. The spring
salamander
is warm blooded, which means that wherever it goes its body
temperature
stays the same.
Diet and Feeding Habits
What does a spring salamander eat? Well, a spring salamander likes to
eat insects that live near or in water. When the spring salamander
goes to hunt for food it stays very still, then attacks. They like to
eat gross things like earthworms and sometimes they even eat each
other.
If you were to handle a spring salamander you would want to be very
gentle because if an adult salamander is handled roughly, then it will
throw up what he just ate. If you were to put the spring salamander
into one of
these groups, omnivores, herbivores, or carnivores,
this cute little thing would be put in the carnivore group. This is
because the spring salamander likes to eat things like insects. The
size of the salamander's prey is determined by the size of the
salamander. They don't eat
things they can't get into their mouths.

Personal Essay
How does diversity strengthen an ecosystem?
I think it strengthens it in many ways. For example if you didn't have different species then there wouldn't be food for some of the other species and if some died then another would die and so on and so on. Diversity strengthens an ecosystems because the fact that there are different types of food makes it easier to survive if one thing runs out.
Different animals are important because they supply food for other
animals. The spring salamander strengthens the ecosystems in many ways.
For example they are a part of the food chain. They supply food for
many animals. They also eat a lot of bugs so the bug population doesn’t
get out of control. As you can see in my examples the spring
salamander is very important because its a link in the food chain. It
doesn’t only eat bugs so that they get out of control but they also
supply food for other animals.
