Alligators spotted chowing down on marshmallows is a peculiar yet increasingly common sight. But why do these apex predators have such an insatiable sweet tooth? In this comprehensive guide, we’ll unravel the mysteries behind alligators’ marshmallow obsession.
If you’re short on time, here’s a quick answer to your question: Alligators like marshmallows because they contain calories and fat that provide energy, and the soft texture is easy for their toothless mouths to eat. The sugar may also be similar to tastes that appeal to alligators in the wild.
Alligators Have a Strong Sense of Smell
Alligators Can Detect Scents from Far Away
Alligators have an incredibly acute sense of smell, allowing them to detect prey from far distances. Their nostrils, located on the end of their snout, can take in large amounts of scent particles. These particles bind to special receptors in the alligator’s nasal chamber, sending signals to the olfactory lobe in their brain that something tasty might be near (1).
An alligator’s sense of smell is thought to be roughly 10,000 to 100,000 times more sensitive than a human’s.
According to researchers, alligators can detect certain smells located over a mile away (2). Their sensitivity allows them to track prey such as fish, birds, turtles, and mammals from far off locations.
Their sense of smell is useful not just for finding food, but also for finding mates and avoiding predators. This powerful ability aids their survival in aquatic environments where visibility is low. Truly, an alligator’s sense of smell is one of its most incredible assets.
Marshmallows Have a Sweet, Distinct Scent
The characteristic scent of marshmallows comes from their main ingredients like sugar, water, air beaten into egg whites or gelatin. When heated, the Maillard reaction occurs which causes the sugars and amino acids to combine, producing hundreds of volatile aromatic compounds that create their signature sweet smell (3).
The scent is distinctive enough for alligators to detect from remarkable distances.
In addition, some marshmallows are flavored or dusted with cocoa powder or other sweet spices. These extra ingredients add more nuance and depth to the already noticeable aroma. Not many natural foods smell quite like roasted marshmallows.
With an unmatched nose, alligators can easily pick up their sweet scent, intriguing them to find the source.
Alligators Need Calories and Fat for Energy
Alligators are ectothermic reptiles that rely on external sources of heat to regulate their body temperature. This means they are cold-blooded and can’t produce their own body heat like mammals and birds. As a result, alligators have some unique nutritional needs when it comes to food and energy.
Alligators Are Cold-Blooded and Burn Calories Quickly
Because alligators are cold-blooded, their metabolisms work much differently than warm-blooded animals. Their bodies do not automatically maintain a consistent internal temperature. Instead, the surrounding water and air temperatures greatly impact an alligator’s body temperature.
This means that when it is cold outside, an alligator’s body cools down too. Their metabolic processes like digestion and brain function actually slow down. Alligators may become lethargic and inactive during cold weather as their bodies enter a state of torpor.
Their appetite and calorie needs decrease.
However, once the ambient temperature warms up, so does the alligator. Its bodily functions speed up again. Their metabolism revs up, and alligators burn through calories more quickly. Their appetite increases, and they need to eat more food to fuel their newly accelerated metabolism.
Since alligators cannot control their own body heat, they rely heavily on external temperatures for their metabolic rate. Colder environments slow their metabolism, while warmer ones cause it to burn calories faster.
This is very different from mammals like humans who maintain an almost constant core body temperature year-round.
Marshmallows Are a High-Calorie, Fat-Rich Food Source
Marshmallows may seem like an odd food choice for alligators. However, they provide two key macronutrients that cold-blooded alligators need in their diet – calories and fat.
Here’s a nutritional comparison of 1 cup of mini marshmallows versus 1 cup of chicken, a more natural alligator food source:
Food | Calories | Fat (g) |
Mini Marshmallows | 308 | 0 |
Chicken (cooked) | 231 | 15 |
Marshmallows provide significantly more calories than chicken – 308 versus 231 calories per cup. The marshmallows are almost pure carbohydrates, while chicken has more well-rounded nutrition with protein and some fat.
However, alligators can efficiently convert the carbohydrates in marshmallows into energy. The quick calories give them fuel to power their metabolism, especially when becoming active in warm weather.
Alligators also benefit from the fat content in foods. Since they are cold-blooded, fat provides crucial insulation to help keep their body warmer. Chicken has significantly more fat compared to the pure carb marshmallows.
But when alligators indulge in marshmallows occasionally, the sweet treats still offer a calorie and energy boost.
Alligators Enjoy Sugary Flavors
Alligators have evolved over millions of years to enjoy sweet tastes, which makes their affinity for marshmallows easy to understand. Here’s a deep dive into why these ancient reptiles crave sugary treats.
Alligators Evolved to Enjoy Sweet Tastes
Alligators’ ancestors evolved to seek out ripe, sweet fruit as an efficient source of energy. Their taste buds developed to find the natural sugars in berries, melons, and other fruits appealing. This gave them an evolutionary advantage, allowing them to easily identify calorie-dense foods.
Modern alligators retain this innate craving for sweet flavors, even though their diets are more focused on meat. The sugary sensation of marshmallows triggers their instinct to consume high-energy foods. So when given the chance, gators enthusiastically gobble up these puffy sugar blobs!
Marshmallows Contain Lots of Sugars
The main ingredient in marshmallows is sugar. A single large marshmallow contains about 4 grams of sugar. Since most bags contain dozens of marshmallows, it’s easy for an alligator to get a huge sugar rush by eating them.
Marshmallows are essentially concentrated sugars shaped into a spongy, soft solid. Common types of sugar found in marshmallows include:
- Sucrose – Regular granulated table sugar made from sugar cane.
- Corn syrup – Sweet thick liquid sugar made from corn starch.
- Dextrose – A simple sugar derived from corn that dissolves quickly.
With such a high concentration of sweet sugars, it’s no wonder why alligators go bonkers for marshmallows! Their taste buds light up from the intense sugary sensation.
Marshmallows Have a Soft, Palatable Texture
Alligators Lack Teeth Needed to Chew Hard Foods
Alligators have a unique set of teeth that are designed for grabbing and tearing, not chewing. They have around 80 teeth in their lifetime, with about 64 teeth in their mouth at one time. The teeth are pointed and cone-shaped, optimized for pierced and held prey rather than chewing up food.
When alligators feed, they typically swallow food in large chunks with minimal chewing. This allows them to swallow their prey whole if it is small enough.
While alligators have incredibly powerful bites for grabbing prey, their teeth are not well-suited for chewing up tough or hard foods. Foods that require extensive chewing like nuts, seeds, or hard-shelled animals are difficult for alligators to eat and properly digest.
That’s why alligators tend to prefer soft, palatable foods that can be easily torn into chunks and swallowed.
Marshmallows Are Soft and Easy to Swallow
Marshmallows have an airy, spongy, and soft texture that makes them a perfect food for alligators. Since they are almost entirely made of sweetened gelatin and air, marshmallows have no tough outer shell or hard interior that needs chewing.
When placed in an alligator’s mouth, a marshmallow will instantly begin dissolving into a soft, pliable texture.
The fluffy gelatin flesh of a marshmallow requires no chewing or tearing before swallowing. Alligators can simply allow a marshmallow to rest on their tongue and dissolve into a viscous liquid that can be easily gulped down.
The sweet taste and smooth mouthfeel of liquefied marshmallow is highly palatable for alligators. Once swallowed into the stomach, the gelatin will continue dissolving until it is fully digested.
In tests performed by researchers at the University of Florida, juvenile alligators were offered various common human foods to find which ones they preferred. Marshmallows ranked highly on the list of foods the alligators ate most readily compared to harder foods like crackers, fruits, or nuts.
The consistency and sweetness of marshmallows make them an ideal soft food for alligators of all ages.
Marshmallows May Mimic Natural Alligator Foods
Some Wild Prey Have Sweet, Fatty Tissues
Alligators are opportunistic predators that feed on a variety of prey in the wild. Some of their common foods like fish, turtles, birds, and mammals contain high levels of fat and rich fatty tissues. For example, fish eggs and birds eggs that gators consume are filled with fats and nutrients to help the embryo develop.
So alligators may be instinctually attracted to foods with a similar fatty, sweet quality like marshmallows.
According to wildlife biologists, alligators also scavenge carcasses and eat dead animals when the opportunity arises. The fatty tissues of decaying animals undergoing decomposition can be both sweet and rich in nutrients.
So the sweet sugary texture of gelatinous marshmallows could imitate the taste sensations similar to rotting meat that appeals to an alligator’s palate.
Marshmallow Texture Resembles Eggs and Larvae
Marshmallows have a soft, squishy texture reminiscent of many of an alligator’s choice prey items. For example, alligator food like fish eggs, turtle eggs, bird eggs, and insect larvae have a jiggly, bouncy texture with membrane encasings.
When an alligator bites into a marshmallow, the gelatinous insides may replicate the sensation of rupturing eggs and crunching larvae.
Studies show that alligators locate their prey primarily through touch, vibration, and movement in water rather than vision alone. So an alligator attracted to the white color or sweet scent of a marshmallow may approach and bite it.
Then the sensation of the marshmallow’s soft bouncy texture and sweet taste could mimic natural fatty prey, reinforcing the alligator’s instinct to consume it.
Alligator Prey Items | Texture and Taste |
Fish eggs | Soft, membrane spheres filled with fat and protein |
Turtle eggs | Leathery bouncy spheres high in fats, nutrients |
Bird eggs | Hard outer shell, fatty, rich yolk inside |
Insect larvae | Jiggly, fatty bodies high in nutrients |
So while alligators don’t hunt marshmallows in the wild, they contain some sensory qualities similar to an alligator’s natural diet. This may explain why alligators exhibit such a strange affinity for these puffy sugar cubes!

Conclusion
In the end, alligators’ penchant for marshmallows stems from the treats’ strong scent, high calorie content, sweet flavor, soft texture, and similarity to the eggs and larvae gators eat in the wild. While their love of marshmallows may seem outlandish, it makes perfect sense when you consider alligators’ physiology and evolutionary instincts.
Next time you spot a gator snacking on marshmallows, you’ll understand why they can’t resist these puffy, sugary cubes!
