Rabbits are much more than the cute, carrot-munching creatures pop culture makes them out to be. They can dig sophisticated tunnels, grow to weigh more than 20 pounds, and even eat their own poop. Here are some more facts worth knowing about the beloved mammals.

1. They can't live off carrots.

Cartoons suggest that rabbits can happily survive on a diet of carrots alone. But in the wild, rabbits don’t eat root vegetables—they’d much rather munch on greens like weeds, grasses, and clovers. That doesn’t mean you can’t give your pet some carrots as a snack from time to time, but don’t overdo it: Carrots are high in sugar and contribute to tooth decay in 11 percent of pet bunnies.

2. Some rabbits are as big as a toddler.

Not all rabbits are cute and tiny. Some, like the Flemish giant rabbit, grow to be downright monstrous. This rabbit breed is the world's largest, reaching 2.5 feet in length and weighing up to 22 pounds. Fortunately these giants are the gentle kind, which makes them popular pets.

3. Baby rabbits are called kittens.

Nope, not bunnies, technically. Another word for the young is kits. Mature females are known as does while adult males are called bucks. Bunny, meanwhile, falls into the same category of cutesy terms as kitty and doggy—they're not scientific, but everyone will know what you mean.

4. There's some truth to the phrase "breed like rabbits."

Rabbits really are a busy bunch. A rabbit is ready to start breeding at just 3 to 8 months old. Once they reach that point, they can copulate eight months out of the year every year for the rest of their 9- to 12-year lifespan. A doe's reproductive system doesn't follow cycles; instead, ovulation is triggered by intercourse. After a 30-day gestation period she'll give birth to a litter of about four to 12 kits.

5. Rabbits "binky" when they're happy.

If you spend enough time around rabbits, you may be lucky enough to witness one of the cutest behaviors in nature. A bunny will hop when it's happy and do a twist in mid-air. This adorable action has an equally adorable name: It's called a binky.

6. They eat their own poop.

One rabbit behavior that is significantly less adorable: After digesting a meal, rabbits will sometimes eat their own poop and process it a second time. It may seem gross, but droppings are actually an essential part of a rabbit's diet. They even produce a special type of poop called cecotropes that are softer than their normal pellets and meant to be eaten. Rabbits have a fast-moving digestive system, and by redigesting waste, they're able to absorb nutrients their bodies missed the first time around.

7. Rabbits groom themselves like cats do.

Rabbits are remarkably hygienic. Like cats, they keep themselves clean throughout the day by licking their fur and paws. This means rabbits generally don't need to be bathed by their owners like some other pets.

8. They can't vomit.

While a cat can cough up a hairball after a long day of self-grooming, a rabbit cannot. The rabbit digestive system is physically incapable of moving in reverse. Instead of producing hairballs, rabbits deal with swallowed fur by eating plenty of roughage that pushes it through their digestive tract.

9. Their vision covers nearly 360 degrees.

It's hard to sneak up on a rabbit: Their vision covers nearly 360 degrees, which allows them to see what's coming from behind them, above them, and from the sides without turning their heads. The trade-off is that rabbits have a small blind spot directly in front of their faces.

10. They are really good jumpers.

Those impressive back legs aren't just for show. Rabbits are built for evading predators in a hurry, and according to Guinness World Records, the highest rabbit jump reached 3.26 feet off the ground and the farthest reached nearly 10 feet. There are even rabbit jumping competitions where owners can show off their pets' agility.

11. Their teeth never stop growing.

Like human fingernails, a rabbit's teeth will keep growing if given the chance. A rabbit's diet in the wild includes a lot of gritty, tough-to-chew plant food that would eventually wear down a permanent set of teeth. With chompers that grow at a rate of up to 5 inches a year, any damage that's done to their teeth is quickly compensated for. The flip-side is that domestic rabbits who aren't fed abrasive foods can suffer from overgrown teeth that can make it difficult for them to eat.

12. They live in elaborate tunnels called warrens.

Rabbits dig complex tunnel systems, called warrens, that connect special rooms reserved for things like nesting and sleeping. The dens have multiple entrances that allow the animals to escape in a pinch, and some warrens are as large as tennis courts and extend 10 feet below the surface.

13. Their ears help them stay cool.

A rabbit's ears serve two main purposes. The first and most obvious is hearing: Rabbits can rotate their ears 270 degrees, allowing them to detect any threats that might be approaching from close to 2 miles away. The oversized ears also have the added benefit of cooling rabbits down on a hot day. More surface area means more places for body heat to escape from.

14. They're hard to catch.

If their eyes, ears, and powerful legs don't give them enough of a head start when avoiding predators, rabbits have even more tricks to rely on. The cottontail rabbit moves in a zig-zag pattern when running across an open field, making it hard to target. It also reaches a top speed of 18 mph—they really are "wascally wabbits."

What's That Thing That Hangs Off a Turkey’s Face?

That thing is called a snood. And it's there to let the other turkeys know that its owner is kind of a big deal.

When a male turkey—known as a tom—wants to mate, he faces two hurdles. One is his potential mates, the female turkeys (a.k.a. hens). In the realm of turkey mating, the hens wield the power of choice and the toms have to get a hen's attention and win the opportunity to reproduce. Come mating season, a tom will strut around, gobble, puff out his chest, fan his tail, and drag his wings to attract the hens, who then pick which of the toms they’ll mate with.

The second problem for a tom looking for love is the other toms in the area. They’re all competing for the same limited number of hens. Sometimes a good mating display isn’t enough to win a mate, and toms will attack and fight each other to secure a hen.

This is where the snood comes in. That goofy-looking piece of dangling flesh helps a tom both with choosy hens and with competition from rival males. Having a long snood almost always means that a hen will want to mate with him and that another tom will back down from a fight.

Dudes and their snoods

When two toms are trying to establish dominance, they’ll size each other up. Then they'll either fight, or one will flee.

In the late 1990s, Dr. Richard Buchholz, an animal behaviorist who focuses on turkeys, wanted to figure out which, if any, characteristics of a tom turkey could predict how they fare in dominance fights. That is, did bigger turkeys tend to win more scuffles? Did older ones? He also wanted to see if the turkeys used any of these predictive cues when sizing each other up. He looked at various characteristics of dominant toms that fight and win, and compared them to those of subordinate toms that lose fights or run from them. Of all the characteristics he looked at, only “relaxed snood length” seemed to be a reliable predictor of how a tom would do in bird-vs-bird combat. The dominant males, the ones who won fights and got a choice mate, had longer snoods.

With that in mind, Buchholz looked at how toms reacted to other toms with snoods of varying sizes. The birds tended to avoid confrontation with other males with longer snoods, and wouldn’t even feed near them. A big snood, this suggests, says to the other turkeys that this is a tom you don’t want to tangle with. Buchholz noted that snood length correlates with age, body mass, and testosterone, so, to competitors, the snood could be a good indicator of a tom’s aggressiveness, age/experience, size, and overall condition and fighting ability.

In the snood for love

Once the males have established who’s going to have a chance to mate, the final choice goes to the hen. While the mating display is the main draw for getting a hen to check him out, a tom’s snood helps him out again here.

Like it did for the other males, a tom’s snood signals a lot of information to a female assessing potential mates—it indicates how old and how big he is, and even says something about his health. In another study, Buchholz found that longer-snooded toms carried fewer parasites. If a hen wanted to choose a mate with good genes that might help her offspring grow large, live long, and avoid parasites, a tom’s snood is a good advertisement for his genes. In that study, hens showed a clear preference for toms with longer snoods. In another experiment years later, Buchholz found that healthy hens again showed a strong preference for long snoods and that hens with their own parasite problems were less picky about snood length and checked out more potential mates—perhaps, Buchholz thinks, because the hens recognized their own susceptibility to infection and were willing to invest more time searching for a tom with genes for parasite resistance that would complement their own—but still showed some preference for longer ones.

While a snood might look goofy to us, for a turkey, it’s integral to the mating game, signaling to other toms that they should get out of his way and letting hens know that he’s got what they’re looking for.

Journey to the Monarch Mosh Pit

Each fall, millions of migrating monarchs return to Mexico to wait out winter. The gathering makes Woodstock look like a business conference. Here’s how they get there.

Mosh Pit

In the mountains of central Mexico, the butterflies crowd on the branches of oyamel fir trees. The trees provide a perfect microclimate that prevents the butterflies from getting too hot or cold.

Texas Toast

After winter, the butterflies fly north to Texas in search of milkweed, where they lay their eggs. Many adults will die here; northbound monarchs generally live only three to seven weeks.

Juice Cleanse

One of the reasons monarchs love milkweed? Protection. As caterpillars, they absorb the toxins in the plant, which makes them less tasty to birds.

Connecting Flight

Eventually, a new generation of butterflies will make its way north to Canada. It takes multiple generations of butterflies to reach their final, most northerly destination.

Dine and Dash

On the way, butterflies will eat practically anything. Sure, there’s nectar—but they’ll also slurp the salts in mud.

Catching Air

When fall returns, a new generation of monarchs rides the air currents more than 3000 miles back to Mexico. They navigate by calibrating their body clocks with the position of the sun. (An internal magnetic compass helps them navigate on cloudy days.)

Latitude Adjustment

Monarchs “are one of the few creatures on Earth that can orient themselves both in latitude and longitude,” The New York Times reports—a feat sailors wouldn’t accomplish until the 1700s.

Southern Charm

Miraculously, each generation of southbound monarchs lives up to eight months—six times longer than their northbound descendants. Their longevity might have something to do with a process known as reproductive diapause (which is a fancy way of saying that the insects won’t breed until winter ends).
