The American Crocodile Essay

The American crocodile is a very unique animal. It is mostly found in many parts of the United States, but this
species of crocodile lives in the Florida Everglades. The America crocodile’s scientific name is a very complicated
and confusing name. Its scientific name is Crocodylus acutus.

The American crocodile is a large reptile with a long, cigar-shaped body, short legs, and a powerful tail and deadly
jaws. Its heart has four chambers, preventing an admixture of venous and arterial blood. Their keen senses are very
well developed and exact. Its pointed snout and long, partially exposed sharp teeth help distinguish it from its close
relative, the alligator. The crocodile’s eyes and nostrils are higher than the rest of its head. Even though crocodiles
are aquatic, their arms and legs are of a greater use in walking on the land than in the water. Their tails are very
important to them in many ways. One way is they use their tails for swimming, courtship, and sometimes in
capturing their prey. The crocodile is also very different from its cousin, the alligator. As I said earlier, the crocodile
has as more of a pointed snout and the alligator has a more rounded snout. The American crocodile is dimorphic,
meaning you can tell the difference between the ma!
le and female. The way you can tell is by the size; the male is a bit larger than the female. The crocodile babies are
distinctly greenish with black markings on its body. The young adults are an olive green, while the oldest crocodile
is a very dull gray. The crocodile spends a considerable amount of time in the water, swimming and hunting.
Although the crocodile is not considered a marine or oceanic animal, it has actually been sighted far out at sea and
has traveled many miles to reach isolated volcanic islands.
The crocodile lives in an underground hollow, large burrows, or in sand dunes. If the female crocodile is ready to lay
her eggs but has no place to bury them, she will find an empty one; she will take it over as her own.
The map above shows the areas in which the American Crocodile can be found.

The picture above is a graphic representation of the Florida Everglades, and area where the American Crocodile can
be found.

The American is both a predator and prey. It is a predator because it eats animals smaller than it is and will almost
eat anything. It is prey because humans are hunting them and eating the meat off of them. Their place in the food
chain is:
The crocodile eats many things such as fish, tadpoles, tarpon, and frogs. When it is ready to hunt for food, the
crocodile will usually camouflage itself by swimming very silent in the water, swim under the water silently, or they
sneak up on the prey and snap it into its jaws. Since the crocodile is unable to digest bones and cartilage, it has to
snap to prey onto the water to breaks all its bones. It also must be careful where to bite in case of cartilage or bone.
Something that I think is very unique about the crocodile is that it can swim silently without anyone knowing. When
responding to an attack threat it growls and makes a hissing noise to say that it is prepared to fight. The crocodile
doesn’t migrate; it stays in one place year round. The crocodile have a language all to themselves. It communicates
by making noises to identify each other. The crocodile lives in packs and usually hunt in packs too. Their natural
enemies are humans; we are enemies because we kill them for their skin to make accessories.
When a crocodile is ready to mate, the female tries to a strong male’s attention through visual, tactile, olfactory, and
audible signs. The female initiates the courtship display, but must also let the male know she has entered his territory
for a reason. The female exposes her throat by lifting her head in a peaceful intent. The male and female nuzzle their
heads together and the courtship begins. When the male is ready to mate, he makes the water “dance” which attracts
a female miles away. The female lays a clutch of 40 eggs, of which only a few survive to become adults. The baby’s
measure approximately 24 centimeters. The female stands guard over her nest and sometimes the male will also
help. Gestation usually takes three months. When the babies are ready to emerge, they will cry and yell out to their
mother. She will dig a hole into the burrow and pull the eggs out. When the eggs come out into the air, the babies
hatch themselves. The temperature determines the!
baby’s sex. 90 degrees is a male and 70 degrees is a female. When an enemy is too close to the nest, the female will
growl and hiss at it and drive it away.
Decline in numbers can be credited to demand for the high-quality skin. Continuing hunting, although on a lesser
scale, combined with habitat destruction are the most recent threats. It has been reported that the collecting of large
numbers of mature adults for farm stocks could affect the breeding structures of small populations if not monitored.

Although information on population and behavioral ecology is well documented, little survey data is available.
Current studies will hopefully improve this situation. Presently, it appears that the species is depleted to a significant
extent over most of its range, particularly so over almost a third of the crocodile is completely protected in most
countries where it occurs, but the enforcement of this protection is often inadequate. In addition, it can be difficult to
identify other species, enforcement more difficult. Other measures include farming and ranching in a small number
of countries. This is likely to expand (e.g. Colombia, Jamaica), although the status of wild populations from which
stock would no-doubt be taken must be carefully monitored, once basic survey data has been compiled. A
percentage of farmed stock is incorporated into a reintroduction program (this strategy is necessary in Cuba the
recovery of wild populations, as farming has been successful). In oth!
er areas Venezuela), much crocodile habitat exists, but there are few crocodiles remaining. Restocking program
would help to ensure the continued survival of these populations. The US, the Fish and Wildlife service formulated a
recovery plan in 1984 for this centering around habitat protection and management, regular population surveys,
reduction in mortality (increased education, plus other measures such as road crossing culverts) and the
consideration of captive propagation. Major threats in the US are from habitat removal (e.g. mangrove swamps
outside the Everglades National Park) and direct human disturbance (e.g. shooting, road-kills, gill-net fishing,
vandalism and other disturbance of nests) which, although low, may be higher than the recruitment rate of the
remaining crocodile population. The American Crocodile is indeed endangered. Many people in lower Florida have
tried to save these animals and they are gradually succeeding.

The American Crocodile was proclaimed endangered on December 18, 1979 and is still included on the
“significantly” endangered list.
In conclusion, I have really learned a lot about the American Crocodile and its very different characteristics. I also
learned much about the endangered species movement and their dedication to preserving a wonderful animal, the
American Crocodile.
