Male turtles and alligators have penises, while most birds and tuataras lack such organs entirely, instead transferring sperm through direct cloacal contact. Snakes and lizards have paired copulatory organs termed hemipenes. In all cases, male reptiles who possess intromittent organs carry them internally.
In the US, you are more likely to be attacked by an alligator than a crocodile, although attacks by either are very rare. The average annual fatality rate for death by alligator in the US is actually only 0.3. That means on average, one person dies every three years.
Nile Crocodile (Crocodylus niloticus)
The species easily claims the title of the most-dangerous crocodilian, since it is widely thought to be responsible for more than 300 attacks on people per year.Crocodiles are often regarded as much more aggressive than alligators. While you should avoid contact with both animals at all costs, alligators in the Everglades tend to be more docile than crocodiles, only attacking if hungry or provoked.
Alligators are aggressive, and they dominate the winding waterways of the Everglades. They feed off other animals in the 'glades and can detect even the slightest movement in the water. So, if you're wondering if it's safe to go swimming in the Everglades – the answer is ABSOLUTELY NOT.
After mating has taken place, the female builds a nest of vegetation. Then, around late June and early July, the female lays 35 to 50 eggs. Some females can lay up to 90 eggs. The eggs are then covered with vegetation and hatch after a 65-day incubation period.
Snout shape: Alligators have wider, U-shaped snouts, while crocodile front ends are more pointed and V-shaped. For alligators, the upper jaw is wider than the lower one, so when they close their mouths, all their teeth are hidden.
How fast can a crocodile run?
Saltwater crocodile: 24 – 29 km/h
Nile crocodile: 30 – 35 km/h
American crocodile: 32 km/h
Florida crocodiles: Man-eating Nile beasts confirmed in swamps. DNA tests have confirmed that three man-eating Nile crocodiles have been found living in Florida's swamps. Unlike local alligators, the species preys on humans and is thought to be responsible for up to 200 deaths a year at home in sub-Saharan Africa.
Alligators are primarily freshwater animals and they do not live in the ocean. Alligators probably aren't one of them. While alligators can tolerate salt water for a few hours or even days, they are primarily freshwater animals, living in swampy areas, rivers, streams, lakes, and ponds.
American crocodiles (Crocodylus acutus) are a shy and reclusive species. They live in coastal areas throughout the Caribbean and occur at the northern end of their range in south Florida. They live in brackish or saltwater areas and can be found in ponds, coves, and creeks in mangrove swamps.
Crocodiles and alligators belong to a group of reptiles called crocodilians, which are the largest of the living reptiles. Of the 23 different species of crocodilians in the world, 2 species are native to the United States, and south Florida is the only place where both of these species coexist.
Distribution and habitat
Today, the Cuban crocodile can only be found in Cuba's Zapata Swamp and the Isle of Youth, and it is highly endangered. It formerly ranged elsewhere in the Caribbean. Fossils of this species have been found in the Cayman Islands, the Bahamas and the Dominican Republic.Mating Cuban crocodiles and American crocodiles are creating hybrid offspring that threaten the survival of the Cuban species, which has dwindled to about 4,000 wild animals in two isolated Cuban swamps. American crocodiles, which are found throughout the Caribbean, are not considered threatened by IUCN.
An estimated 1,000 to 2,000 American crocodiles live in Mexico, Central America and South America, but population data is limited. An additional 500 to 1,200 are believed to live in southern Florida.

THE ANSWER
- Experts say the best way to fight off a crocodile is to poke its eyes in the hope it will let go.
- But the most reliable way to escape its jaws is to stay alert and not get attacked in the first place.
- If you spot a crocodile, it is best to back away slowly.
It's illegal to kill wild alligators
In Florida, however, alligators can only be killed if deemed a nuisance by the Florida Fish and Wildlife Conservation Commission or by applying to the Statewide Alligator Harvest Program, where there are specific timeframes and areas where permit holders can hunt.Black caimans have a broad diet, feeding on fish and other reptiles as well as rodents such as the capybara (which can grow as large as 4 feet [1.25 meters] long). Adult male black caimans often grow longer than 13 feet (about 4 meters); larger specimens have been known to attack people.

Alligators are native to only the United States and China. Southern Florida is the only place where both alligators and crocodiles live side by side. American alligators live in freshwater environments, such as ponds, marshes, wetlands, rivers, lakes, and swamps, as well as in brackish water.
The saltwater crocodile is not a big, fishy friend, like the shark. He is an opportunistic, aggressive, giant beast. Crocodiles attack hundreds to thousands of people every single year. Depending on the species, 1/3 to 1/2 are fatal.
They are occasionally being encountered inland in freshwater areas of the SE Florida coast as a result of the extensive canal system. The American crocodile inhabits brackish or saltwater areas and can be found in ponds, coves, and creeks in mangrove swamps.
That crocodiles attack when it's warmer is thought to be because they are ectothermic (cold blooded) creatures. That is, they depend on the sun's heat for energy. This means they will hunt more when it's warmer.
The diet of the Nile crocodile is mainly fish, but it will attack almost anything unfortunate enough to cross its path, including zebras, small hippos, porcupines, birds, and other crocodiles. It will also scavenge carrion, and can eat up to half its body weight at a feeding.
How does the otter actually kill the gator? It doesn't, not directly. First, that's a pretty hard animal to bite through. The armor on the back is made to deflect bites from other alligators, so it's very tough.
But according to wildlife ecologist James Perran Ross of the University of Florida, officials estimate that crocs kill about 1,000 people per year — 100 times more than the 10 people sharks kill per year. Here's why crocodiles are much deadlier than sharks.
The Nile crocodile is one of the most dangerous species of crocodile and is responsible for hundreds of human deaths every year. It is a rather common species of crocodile and is not endangered despite some regional declines or extinctions.
Description. Since Gustave has not been captured, his exact length and weight is unknown, but in 2002 it was stated that he could be "easily more than 18 feet (5.5 m)" long, and weigh more than 2,000 pounds (910 kg).
Crocodile monitors are found on the island of New Guinea. Crocodile monitors weigh up to 90 kg (nearly 200 pounds). Although the Komodo dragon (V. komodoensis) is larger by weight, fully grown crocodile monitors are longer, reach up to 5 meters (about 16 feet) in length from snout to tail.
