By Steven woodrich

Know the difference• Spices name- Alligator

• You can't see an alligator's teeth when it's mouth is closed; its lower teeth fit snugly into pits in the upper jaw. In contrast, a crocodile's lower teeth are always visible.

• crocodiles have a thinner snout.

• crocodiles have a light tan appearance.

• Crocodiles can be found all over the world.

• Alligators have a broad snout• Alligators tend to be grayish

black in color• Alligators can only be found in

the southeastern United States and in some parts of China.

Reproduction of Alligators

• Type- Sexual• Sexually active-Both sexes

grow to about 122 cm (4 ft.) by age 5. After this age, female growth begins to slow, presumably channeling energy towards reproduction, while males continue to grow fairly rapidly. Males and females become sexually active when approximately 2.1-2.7 meters (7-9 ft.) in length.

• Have been some cases of reproduction asexual but are vary rare

• Ovary- female reproductive organ in which ova or eggs are produced,

• Infundibulum-and oviduct tube compared with the transition zone and the uterus

• Magnum- narrow tube leading to the isthmus.

• Isthmus-.A narrow organ, passage, or piece of tissue connecting two larger parts.

• Vagina- The passage leading to the vent• Vent- the exit for all waste and eggs

• The male American alligator arches his head and tail and bellows sometimes if the alligators back is submerged the vibrations looked like rain hitting the water

• Alligators mate by the female lifting up her tail and the male lifting up his legs to meet her vet once together sperm is transmitted over to the female to fertilize her eggs,

Mating/cupellation

Gestation of eggs

gestation• The incubation period of

alligator eggs is approximately 65 days. During this time the female alligator stays on the alert to guard.

• Also the temperature of the nest decides the sex of the offspring between 90 and 93 degrees Fahrenheit will produce males and anything below or above that will produce females.

• Also these eggs once laid are not water proof and will die if submerged for to long.

On guard mother

Females• They are on guard 24/7• Sometimes going

without food for mouths

• Protecting against females, males, lizareds,snakes,and any type of dog or bird that will try and get at the eggs

Male• Will eat the eggs if

given the chance but usually leave after mating

Offspring

• The offspring once hatched will stay close to its mother for a year .

• She will guard them by keeping them in her mouth.

• Offspring feed at this time off of bugs and small fish.

Problems?!?!• Alligators don’t have many

genetic problems they do however have people problems the American alligators in the 1940s where nearly wiped out by over hunting and today there numbers are up

• Also flooding has a major impacted during the breeding season many of the eggs could drowned if the female doesn't move the nest far up the bank .

• Last some females are killed during the act of mating which can lead to problems.
