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

A fully grown 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.

  • Snakes
  • Frogs
  • Turtles
  • Wild boars
  • Wilderbeasts
  • Crabs
  • Sharks
  • Baby elephants

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.
