ALLIGATORS
Florida’s
Alligators – Fearsome and Fascinating
Although crocodilians – as alligators and crocodiles are called –
inspire fear and fascination in us, few people know they are an
important part of the ecology of Florida’s wetlands. Two crocodilians
are native to the United States, the American alligator and the
American crocodile. The range of the American alligator, found only
in the southeastern part of the country, is restrained by cold
temperatures and the distribution of wetlands. The American crocodile
is even more sensitive to cold and its range, which includes the
southern tip of Florida, is tropical.
Alligators and crocodiles are protected by state and federal laws; the
alligator is listed as threatened and the crocodile as endangered
under the federal Endangered Species Act.
Crocodilians are relics of the great Age of Reptiles, and today only
21 crocodilian species remain, many of which are in danger of
extinction from conflicts with man. Of all the reptiles, crocodilians
are the largest and have the most complex behavior, including
elaborate courtship displays, nest-building behavior and social
rituals. Males move from pond to pond during breeding season to
mate. Alligator courtship begins as the weather warms in early spring
and features a varied sequence of behaviors including bellowing, head
slapping, snout touching and bubble blowing. The bellowing of
courting alligators is a familiar sound in the swamps in the spring.
Female alligators construct elaborate nests of compacted vegetation.
The eggs are incubated by the heat from rotting vegetation. Twenty to
50 eggs incubate for about two months and the mother may stay nearby
to ward off predators. Shortly before hatching, baby alligators begin
to emit a high-pitched barking sound. The mother responds by opening
the nest and sometimes helping her young to hatch by carefully
cracking the eggshells in her mouth. Young alligators may stay with
their mothers for a few days to several months.
Alligators eat anything they can catch: fish, turtles, raccoons,
birds, dead animals, and even other alligators. Alligators have been
known to injure or kill people or pets. Most attacks occur in the
water, suggesting victims are mistaken for prey. The Florida Game and
Fresh Water Fish Commission receives thousands of nuisance complaints
a year. Many of these alligators must be killed because there are few
places where they can be relocated.
As a very visible member of the wetland community, the alligator is a
barometer of how well wetlands are faring. Now that the alligator has
been saved from extinction, many difficult decisions regarding water
management and land development need to be made concerning their
future and their habitat.
Did you know…….??
·
The largest alligator ever
recorded in Florida was 17 feet 5 inches long.
·
The sex of an alligator is
determined by the temperature at which the egg is incubated.
Hatchlings from eggs incubated at or below 86 degrees are all female
and at or above 93 degrees are all male.
·
Alligators contribute to the
health of wetlands by maintaining ponds that serve as vital dry season
refuges for aquatic life.
This is mating season for alligators. Enjoy the display in our
community, take photos and try not to disturb them. Meet some of our
VGCC alligators on
Critters Corner!
