Australian saltwater crocodiles, formidable apex predators, evoke images of power and cunning. While their hunting prowess is well-documented, a common question arises: Do Crocodiles Hide Their Food? Let’s delve into the fascinating feeding habits of these reptiles and explore the truth behind this intriguing behavior.
Australian saltwater crocodiles might look terrifying but they can be quite romantic lovers, according to crocodile hunter Steve Irwin.

Crocodile Feeding Habits: More Than Just a Big Bite
Crocodiles are opportunistic predators with a powerful bite and a unique feeding strategy. They are known for their “death roll,” a spinning motion used to tear off manageable pieces of flesh from larger prey. But what happens when they can’t consume their entire kill at once?
The Mystery of the Submerged Stash
One of the popular stories about crocodiles is that they prefer to hide their food under a submerged log until it is rotten.
Crocodiles do tend to store carcasses in mangroves or under the water, Graham Webb and Charlie Manolis suggest this may not be because they prefer rotting flesh. Perhaps, they suggest, rotten food may be better than no food at all – but more to the point, a rotten carcass will attracts scavengers such as turtles and mud crabs – which are of course, fresh food.
Why Crocodiles Cache Their Kills: Unveiling the Reasons
While the image of crocodiles intentionally hiding food to let it rot is pervasive, the reality is more nuanced. There are several reasons why crocodiles might cache their kills:
- Securing the Meal: A large carcass is a valuable resource, and a crocodile needs to protect it from scavengers and other predators. Submerging the kill in water or wedging it under a log can prevent others from stealing it.
- Facilitating Decomposition: While crocodiles don’t necessarily prefer rotten meat, slightly softened flesh is easier to tear and digest. Submerging the carcass can expedite the decomposition process.
- Attracting Further Prey: As the carcass decays, it attracts scavengers like turtles and mud crabs. These creatures, in turn, become a readily available source of fresh food for the crocodile.
From Hatchlings to Adults: A Dietary Progression
The diet of crocodiles evolves as they mature:
- Hatchlings: Young crocodiles feed primarily on crabs, prawns, and shrimps found in mud banks and shallows. Insects also supplement their diet.
- Juveniles: As they grow larger (up to two meters in length), their diet expands to include birds, rodents, water snakes, and fish.
- Adults: Mature crocodiles are opportunistic predators that will eat almost anything that moves near the water, including large mammals. They also scavenge on carrion.
Conservation Success and Ongoing Challenges
Before 1971, when crocodiles were declared a protected species in the Northern Territory, they were hunted close to extinction. But since achieving legal sanctuary crocodile numbers have boomed from about 3000 to 60,000, one of the great conservation success stories in Australia.
However, increasing crocodile populations have led to conflicts with humans. Proposed culling programs and the development of crocodile safari hunting remain controversial issues.

The Truth About Crocodile Food Caching
So, do crocodiles hide their food? The answer is a qualified yes. While they don’t intentionally rot their food, they do cache it for various reasons, including security, facilitated digestion, and attracting new prey. These behaviors highlight the cunning and adaptability of these apex predators. The truth, as always, is more complex and fascinating than the myth.
