How Long Can Crocodiles Go Without Eating: Detailed Facts


One of the toothiest animals on the earth is a crocodile. As if their razor-sharp teeth weren’t scary enough, there’s also a slew of unexpected facts regarding their appetite.

Crocodiles are aggressive predators, but they can go months or even a year without eating. A crocodile’s bodily system is designed in such a way that it can conserve all of the energy it gets from its meal. Crocs can even shut down and survive for a long time on their own tissue in extreme circumstances.

It might also be surprising to learn that in most extreme cases, larger crocodiles cab go without food for as long as three years. 

Surprisingly crocs! We say this because there are several startling facts, which we will discuss in the following post. Our primary focus would be on determining how long a croc can go without eating and the facts surrounding it.

We’ll look at one of the world’s most toothy predators’ feeding habits and behaviors. 

How often do crocodiles need to eat?

Crocodiles fall under the category of larger reptiles. They can measure anywhere between 5.6 feet to 23 feet, weighing up to 2000 lbs

An adult crocodile can consume 50 complete meals per year to maintain their size and weight. Young crocodiles only eat 1-2 times a week. These figures, however, should not be taken at face value. In reality, a crocodile will eat when it is hungry, and its next eating time will be determined by the amount of the meal it consumes and the time it takes to digest it.

A croc’s stomach, however, is extremely acidic and can dissolve anything, including bones, tusks, and hooves. So, we can assume that these reptiles do not take many intervals between meals.

Crocodiles are among the world’s ancient living species. They live for a prolonged lifespan, in which they occasionally encounter food scarcity.

Crocs, however, can go for long periods without eating. They are, after all, cold-blooded reptiles, which means they need less energy and can hoard it for later. They are also slow-moving creatures when not on the hunt, allowing them to save energy and go without food.

However, it’s important to remember that crocs require a hearty meal to go without food for an extended period.

What is crocodiles’ favorite food?

Crocs are among apex predators and active carnivores. However, depending on where they live, their food patterns and preferences can differ substantially.

Crocodiles are promiscuous feeders, meaning they will consume anything edible, that they can ambush and cross their path. They are not fussy eaters and their diets are incredibly versatile, depending on the area they live. These cold-blooded reptiles, on the other hand, have a few favourites.

Some food items crocodiles love to feed on include:

  • Fish
  • Snakes
  • Frogs
  • Turtles
  • Wild boars
  • Wilderbeasts
  • Crabs
  • Sharks
  • Baby elephants
  • Baby rhinos, etc

But the diet of crocs in captivity might vary from those living in wild. Although meat-based, in zoos, crocodiles mostly eat:

  • Fish
  • Beef
  • Rats
  • Mice
  • Chicken, etc.

Crocs, when compared to sharks, are similar to great white sharks in that they are opportunistic feeders. In other words, if these reptiles are hungry, they will devour everything they can capture.

Crocs are robust creatures who may live for days or months without eating. But what makes them so resilient in the face of a lack of food?

Crocs’ cold-bloodedness is one of the main reasons they can survive without nourishment. Crocodiles can adjust their body temperature by absorbing heat from their environment. As a result, these reptiles don’t have to eat as frequently to keep their bodies warm. They can also use their stored energy to keep going if there is a food shortage.

Crocodiles’ bodies are also adapted in such a way that they can collect practically all of the energy from their food and store it for later use. Crocodiles may also lower their heart rate to just two or three beats/minute while they are not moving. As a result, they can conserve energy in order to survive without food.

How much food do crocodiles need to survive?

Considering the large size of crocodiles, it’s always interesting to see how much food they need to eat to survive.

A crocodile’s meal should measure about 5% of its overall weight, according to experts. To put it another way, these reptiles devour about 2-5 lbs per day like a breeze. A croc’s daily food intake, however, is directly proportional to its size, weight, and access to food. As a result, it’s not unusual that a crocodile with plenty of food would eat more than 2-3 lbs every day.

It’s worth noting that crocs are cold-blooded species that can store energy from their meals. As a result, they require less food than animals with warm bodies.

Crocodiles can die out of starvation. Crocs can suffer from old-age difficulties such as tooth loss, impaired eyesight, and so on as they age. Hence, they can’t find the food they need to thrive. Additionally, because crocs grow during their lives, their food requirements grow as well. But, if they do not get the additional food, they may perish from starvation.
