Alligators have existed since the dinosaurs became extinct. Alligators are known for their strength, but they are also among the most attentive parents in the vertebrate world, staying with their young for up to three years. They're both extremely intelligent and well known for their use of tools. Here are ten facts about alligators that you should be aware of!
1 - They have eighty conical-shaped teeth.
1 - They have eighty conical-shaped teeth.
An adult alligator has eighty conical-shaped teeth. Alligators don't have any teeth for chewing or pulverizing food; therefore, they devour it entirely. Moreover, they will replace their lost teeth naturally and should regenerate a lost tooth up to fifty times.
2 - Alligators are ancient.
Alligators and other crocodiles have undergone little organic process modification since the time of the dinosaurs. American alligators first appeared around 84 million years ago, and their ancestors evolved over 200 million years ago. Tortoises and turtles are the only elder species of reptiles. Alligators are usually referred to as archosaur or dinosaur descendants. They don't seem to be, actually; however, they are a lot more closely associated with dinosaurs than with alternative fashionable reptiles.
3 - The eyes of an alligator glow in the dark.
Like cats, alligators have a tapetum lucidum at the rear of every eye. It's a reflective layer behind the tissue layer that will increase the quantity of sunlight for scotopic vision in several nocturnal vertebrates. The color of eyeshine changes from species to species and is red in alligators. Finding the reptiles on a dark night is a good thing.
4 - Alligators eat their young.
One of the largest threats to an American alligator is the alternative alligator. Once alligators are born, they’re sufficiently small to be light-weight snacks for their older neighbors, and a 2011 study calculated that, in one American state lake, larger alligators ate six to seven percent of the juvenile population each year.
5 - They are unable to survive in salt water.
Unlike crocodiles, alligators don't have the glands to expel salt from their bodies, so they cannot swim in saltwater habitats like flowering tree swamps. Now, they'll hunt close to saltwater, particularly in the spring, once there is the best distinction between high and low tide, specialists say. If you see a few eyes peering up from the ocean or a salty lake, it's most likely a croc, not an alligator.

Leading specialists have found that alligators' blood has antibiotic and antiviral properties. Significantly, scientists in the United States discovered that alligator blood can successfully destroy 23 strains of bacteria, including some that are antibiotic-resistant.
7 - Alligators use tools to lure their prey.
Alligators can be reptilian innovators. Scientists have observed Indian and American species of alligator luring water birds by inserting sticks and twigs across their snouts while they continue to be submerged. Once the birds have devoured the twigs for nesting material, the gators chomp.
8 - Temperature determines their sex.
One of the weirder facts concerning alligators is that their gender is set not by polymers but rather by climate. If the temperature within the baby alligator nest is hot, male alligators are born; if the temperature is cool, the babies are female. Eggs are laid by alligators on a dirt pile. Once the eggs are able to hatch, the baby alligators use an "egg tooth" on top of their snouts to interrupt the shell.
9 - Alligators don't have any vocal cords, but they still create sounds.
Alligators are among the foremost vocal reptiles, despite not having vocal cords. By taking in and exhaling activity air from their lungs, they will create completely different sounds to defend their territory, communicate decisions to mates or their young, or fight down competitors—such as a guttural hiss or a candidly terrific bellow.
10 - They look after their young, in contrast to most reptiles.
Female reptiles carry and protect their babies for about two years, ensuring their safety and nourishment. Although they're seen as savage predators, they're famous for being terribly nurturing toward their offspring. Babies grow a few feet per year, so that they are good-sized predators by the time they head off on their own.
