Alligators can survive two to three years without eating. Alligators are one of the few reptiles today that care for their young. Alligators have vibration sensors on their skin that are extremely sensitive -- they can detect even the slightest vibration and get out of harm's way long before it arrives.
In the wild, an older, weaker croc is more likely to face starvation or competition, but even in captivity, the animals inevitably die.
You will be surprised to know that crocodiles, as one of the oldest reptiles of the planet can go for a few months without food, and in extreme cases, they can go up to three years without food. They save energy by moving slow and at times by being motionless too.
Crocodiles in captivity have been known to reach 100 years old. What's most interesting about crocodiles is that they don't die of old age. They do not die from biological aging. Instead, they continue to grow and grow until some external factor causes them to die.
Their stomach acids have a pH of less than 2—in the range of lemon juice and vinegar—and most soft-bodied prey is totally digested in two to three days. If you wound up in a gator stomach, however, you'd stick around a bit longer. Bone and other hard parts can take 13 to 100 days to disappear completely.

There are two main reasons crocodiles survived the asteroid that killed the dinosaurs. First, crocodiles can live for a very long time without food. Second, they lived in places that were the least affected when the asteroid hit Earth.
The 'immortal' jellyfish, Turritopsis dohrnii
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
A croc's metabolism is so evolved that its body uses and stores nearly the entirety of the food it consumes. This is one reason why larger crocodiles can go for over a year without eating a meal. In extreme situations, crocodiles appear to be able to shut down and live off their own tissue for a long period of time.
Snails need moisture to survive; so if the weather is not cooperating, they can actually sleep up to three years.
The oldest crocodile on record was Mr. Freshie, a saltwater crocodile that lived to 140 years old.
“Crocodiles once they're stressed build up a lot of lactic acid. That lactic acid can make their body just too acidic and ultimately it can shut down all their organs and kill them.”
However, animal experts pointed out that crocodiles are normally able to dive and surface for air through their lungs. Thus, the rare drowning that occurred in this case was probably caused by illness, which prevented the crocodile from breathing properly.
They found that, on average, male European lobsters live to 31 years old, and females to 54. There were a few exceptions: one female had reached 72 years old. Lobsters certainly do not live forever. It's not entirely clear where this myth originated, but it is a claim that persists online, often in the form of memes.
They react differently when external stimuli are applied while sleeping and while awake. But the bullfrog, Lithobates catesbeianus show the same reaction in both situations. This indicates that bullfrogs do not sleep. Lithobates catesbeianus is an animal that cannot sleep.
It's a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth.
Regenerating flatworms
This apparently limitless regeneration also applies to aging and damaged tissue, allowing the worms to cheat death indefinitely, according to a study at the University of Nottingham.
The finding published in the journal PLOS Biology also suggested that some shark species were in decline before the asteroid hit but began to thrive after it due to their ability to repair DNA damage.
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
After the asteroid struck Earth long ago, all birds with teeth went extinct. But many of the toothless ones kept living. Some scientists think not having teeth is what allowed these birds to survive. Fossils of early toothless birds show they were able to eat more plant-based food – specifically nuts, fruits and seeds.
Altogether, it seems possible to survive without food and drink within a time span of 8 to 21 days. If a person is only deprived of food, the survival time may even go up to about two months, although this is influenced by many factors.
How long can a Lion go without eating? Lions can go without food for more than a week and then tear into prey, eating up to 50kg of meat at a time - that's almost a quarter of the animal's body weight.
According to Florida Fish and Wildlife, alligators are opportunistic feeders. Juvenile alligators eat primarily insects, amphibians, small fish, and other invertebrates, while adult alligators eat rough fish, snakes, turtles, small mammals, and birds. On occasion, an alligator will eat another alligator.
