Most certainly. All vertebrates have a heart. Most reptiles have a three-chambered heart, but alligators and crocodiles have a four-chambered heart.
Alligators have a 4 chambered heart, just like birds and mammals
Crocodiles and alligators
Yes!! Everything with a heart has skin on it! Alligators just have very rough skin as to a mammal has very soft or lumpy skin.
Most reptiles have a 3-chambered heart. Crocodiles and alligators have a 4-chambered heart.
A four-chambered heart
Crocodiles, alligators, caimans and gharials all have four-chambered hearts.
I'm not exaxtly sure, but I know its quite a while.

No, alligators do not have fur
Adult alligators have few natural predators, but larger alligators or crocodiles, jaguars, and large birds of prey such as eagles may prey on younger alligators. In addition, humans may also consume alligators' eggs or meat.
Pretty much for the same reasons as us - it's simply nature. Dinosaurs also had a four-chambered heart. Unlike mammals, crocodile's right ventricle pumps blood throughout the body. Such a heart perfectly separates blood going to the lungs from that going to the body, which is a requirement for the high blood flow rates and high metabolic rates characteristic of warm-bloodedness. However, living crocodiles are cold-blooded, so it didn't make sense for them to have a warmblooded heart - a mystery!
One year. An alligator can slow its heart beat to as lows as 2 beats per minute.
