11 Amazing Facts About Alligators

Alligators are pretty terrifying as they are, but scientists are making discoveries about the reptilian ambush predators that only add to that reputation.

1. Alligators have an extremely powerful bite.

You really, really don’t want to be bitten by an alligator. A 2004 study of wild and captive alligators found that large individuals bite down with 13,172 Newtons—or 2960 pounds—of force, one of the most powerful bites ever recorded for a living animal [PDF].

2. Alligators can consume almost a quarter of their body weight in one meal.

Alligators don’t have a problem with their eyes being bigger than their stomachs. Thanks to a special blood vessel—the second aorta—they’re able to shunt blood away from their lungs and towards their stomachs, stimulating the production of strong stomach acids to break down their meals faster. Juvenile alligators are capable of eating about 23 percent of their body weight in a sitting, which is equivalent to a 180-pound person eating more than 41 pounds of steak au poivre at a meal.

3. Alligators eat their young.

One of the biggest threats to an American alligator? Other alligators. When alligators are born they’re small enough to be light snacks for their older neighbors, and a 2011 study estimated that, in one Florida lake, bigger alligators ate 6 to 7 percent of the juvenile population every year.

4. An alligator's stomach can dissolve bones.

An alligator stomach is a hostile environment. 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.

5. Alligators have antibiotic blood.

Alligators are tough—and not just because of the bony armor in their skins. Serum in American alligator blood is incredibly effective at combating bacteria and viruses, meaning that even alligators that lose limbs in mucky swamps often avoid infection.

6. Prehistoric ancestors of today's alligators lived 70 million years ago.

Alligator forerunners and relatives have been around for a very long time. The largest was Deinosuchus, a 40-foot alligatoroid that lurked in coastal habitats all over North America around 70 million years ago. Damaged bones suggest that unwary dinosaurs were a regular part of the “terrible crocodile's” diet. Fortunately, modern American alligators don’t come anywhere close to measuring up.

7. Alligator pairs often stick together.

A decade-long genetic study of Louisiana alligators found that some females paired with the same males multiple times, with one in particular choosing the same mate in 1997, 2002, and 2005. Even some females that mated with multiple partners still showed long-term fidelity to particular males.

8. Alligators love fruit.

Alligators aren’t strict carnivores. They also eat fruit when they get the chance, and might be important seed-dispersers. That might not sound so scary at first, but just watch this video of an alligator mashing a watermelon.

9. Despite their short legs, alligators can climb trees.

While on the lookout for alligators, you should remember to occasionally look up. American alligators, as well as several other species of crocodilian, are surprisingly accomplished climbers [PDF]. As long as there’s enough of an incline for them to haul themselves up, gators can climb trees to get to a better basking spot, or get the drop on you, as the case may be.

10. Alligators use tools to lure their prey.

Alligators might be reptilian innovators. Scientists have observed Indian and American species of alligator luring waterbirds by placing sticks and twigs across their snouts while they remain submerged. When the birds go to pick up the twigs for nesting material, the gators chomp. 

11. Alligators have no vocal cords, but they still make sounds.

Alligators are among the most vocal reptiles, despite not having vocal cords. By sucking in and then expelling air from their lungs, they can make different sounds to defend their territory, call to mates or their young, or fight off competitors—such as a guttural hiss or a frankly terrifying bellow.

Turn Your LEGO Bricks Into a Drone With the Flybrix Drone Kit

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

A Prehistoric Great White Shark Nursery Has Been Discovered in Chile

Great white sharks (Carcharodon carcharias) may be one of the most formidable and frightening apex predators on the planet today, but life for them isn’t as easy as horror movies would suggest. Due to a slow growth rate and the fact that they produce few offspring, the species is listed as vulnerable to extinction.

There is a way these sharks ensure survival, and that is by creating nurseries—a designated place where great white shark babies (called pups) are protected from other predators. Now, researchers at the University of Vienna and colleagues have discovered these nurseries occurred in prehistoric times.

In a study published in the journal Scientific Reports, Jamie A. Villafaña from the university’s Institute of Palaeontology describes a fossilized nursery found in Coquimbo, Chile. Researchers were examining a collection of fossilized great white shark teeth between 5 and 2 million years old along the Pacific coast of Chile and Peru when they noticed a disproportionate number of young shark teeth in Coquimbo. There was also a total lack of sexually mature animals' teeth, which suggests the site was used primarily by pups and juveniles as a nursery.

Though modern great whites are known to guard their young in designated areas, the researchers say this is the first example of a paleo-nursery. Because the climate was much warmer when the paleo-nursery was in use, the researchers think these protective environments can deepen our understanding of how great white sharks can survive global warming trends.
