9 Wild Facts About the Bronx Zoo

Even if you’ve never set foot in New York, you almost certainly know of the Bronx Zoo. Opening its doors for the first time in 1899, this sprawling 250-acre wildlife reservation has over 4000 different animals and 650 species. Take a look at a few things you might not have known about one of the world’s most famous zoological retreats.

1. IT WAS CO-CREATED BY A TAXIDERMIST.

William Temple Hornaday was working as a taxidermist for the Smithsonian Institution when he noticed that the nation’s population of bison was shrinking. Eager to promote conservation efforts, Hornaday used his voice with the Smithsonian to spread the word about the threatened species. After a spat with the Institution, he was approached by the New York Zoological Society in 1896 to serve as director of the Bronx Zoo. In doing so, Hornaday helped bring the bison back from the brink of extinction by sending several of the Zoo's bison back out west in 1906. He remained with the zoo for 30 years.

2. IT ONCE HOUSED TASMANIAN TIGERS.

Thylacines, or Tasmanian tigers, were nearing extinction in the early 1900s, but the Bronx Zoo was able to acquire several for exhibition beginning in 1902. The first lived for six years; the next two, arriving in 1912 and 1916, lived only a short time in captivity before perishing. The zoo's last thylacine was secured in 1917. The species was thought to have died out in 1936, but in early 2017, several eyewitness accounts of the distinctive animals were reported in Australia. Zoologists are working to determine if the thylacine might still be alive.

3. THEY EXHIBITED A MAN.

In the most ignoble chapter in the zoo’s history, organizers opened an attraction in 1906 that featured a "Mbuti pygmy” or “bushman”—an African man named Ota Benga. Benga and other tribesmen had been brought to America by anthropologist Samuel Verner at the behest of organizers of the 1904 St. Louis World's Fair so visitors could gawk at them in mock-up villages. When the fair was over, Verner brought Benga and others back to Africa: the two struck up a friendship, and Benga reportedly asked to come back to the States. Verner approached the Bronx Zoo with the prospect of Benga becoming a fixture: Hornaday agreed to let him live on and roam the grounds. Public outrage followed, and Benga was released after just two weeks to the care of an orphanage. He committed suicide in 1916.

4. THE ZOOKEEPERS HAD TO BE TOLD NOT TO MAKE FRIENDS WITH THE BEARS.

Too much children’s literature about cuddly bears may have proven disastrous for early zookeepers at the park. In 1919, Hornaday told the New York Tribune that he had to constantly warn his employees not to try and befriend the mammoth bears housed on the property. Two keepers ignored his advice; both had to be pried from the clutches of the bear and suffered “severe” injuries.

5. IT’S HOME TO A REMNANT OF THE ICE AGE.

Not all of the Zoo’s attractions are feathered or furred. The Rocking Stone sits near the World of Darkness exhibit and packs 30 dense tons into a formation standing 7 feet tall and 10 feet wide. The boulder was carried by glaciers in the last Ice Age. The “rocking” label came from the fact that the stone was so perfectly balanced that it could be moved with slight pressure. The Zoo, fearing someone might one day push it too far, eventually shored up the base to keep it on firmer footing.

6. THEY ONCE SAVED A SPECIES OF TOAD THAT WAS DECLARED EXTINCT.

The kihansi spray toad was in dire circumstances in 2009: A hydroelectric dam in Tanzania had dried up mists showering a five-acre area near Kihansi Gorge, the toad's only known micro-habitat, and the species was officially declared extinct in the wild. Fortunately, Tanzanian authorities had seen the situation coming and allowed the Bronx Zoo to come in and obtain 499 toads to bring back to America. A portion went to the Toledo Zoo; both facilities spent nearly a decade breeding them in a captive assurance population. The Zoos replicated their habitat while Tanzania created a gravity-operated misting system that would restore water. Roughly 100 toads were returned in 2010 as test cases; a full-scale reintroduction followed in 2012.

7. A COBRA ONCE ESCAPED (AND SIGNED ONTO TWITTER).

Animal escapes have been few and far between at the Zoo. One of the most publicized was the the disappearance of a 20-inch venomous Egyptian cobra in 2011. Zoo officials weren’t certain how the reptile broke out of her habitat, but felt confident she would remain in the building. She did, and was found after a week’s search. In the interim, someone on Twitter engaged 203,000 followers with the freed snake’s fictional exploits. It’s still tweeting.

8. IT SET AN ORIGAMI ELEPHANT WORLD RECORD.

In 2016, the Zoo was recognized by Guinness World Records as having the largest displayed collection of origami elephants in the world: 78,564. The display, which was briefly open to the public, was intended to draw attention to the plight of the creatures and their poaching rivals through their 96 Elephants campaign meant to stop the trafficking of ivory. The Zoo is down to just three live elephants, and has vowed not to acquire any more once they pass. On August 3, 2017, Zoo organizers plan to crush two tons of ivory in Central Park as part of the awareness campaign.

9. IT HAS PLANS FOR YOUR POOP.

With thousands of daily visitors, the Bronx Zoo could probably make use of its own sewage system. Instead, the park unveiled an eco-friendly restroom on park grounds in 2006 that captures human waste and diverts it into compost. The system, which uses only six ounces of water per flush, is estimated to save a million gallons of water a year.

8 Tricks to Help Your Cat and Dog to Get Along

When people aren’t debating whether cats or dogs are more intelligent, they’re equating them as mortal foes. That’s a stereotype that both cat expert Jackson Galaxy, host of the Animal Planet show My Cat From Hell, and certified dog trainer Zoe Sandor want to break.

Typically, cats are aloof and easily startled, while dogs are gregarious and territorial. This doesn't mean, however, that they can't share the same space—they're just going to need your help. “If cats and dogs are brought up together in a positive, loving, encouraging environment, they’re going to be friends,” Galaxy tells Mental Floss. “Or at the very least, they’ll tolerate each other.”

The duo has teamed up in a new Animal Planet series, Cat Vs. Dog, which airs on Saturdays at 10 p.m. The show chronicles their efforts to help pet owners establish long-lasting peace—if not perfect harmony—among cats and dogs. (Yes, it’s possible.) Gleaned from both TV and off-camera experiences, here are eight tips Galaxy and Sandor say will help improve household relations between Fido and Fluffy.

1. TAKE PERSONALITY—NOT BREED—INTO ACCOUNT.

Contrary to popular belief, certain breeds of cats and dogs don't typically get along better than others. According to Galaxy and Sandor, it’s more important to take their personalities and energy levels into account. If a dog is aggressive and territorial, it won’t be a good fit in a household with a skittish cat. In contrast, an aging dog would hate sharing his space with a rambunctious kitten.

If two animals don’t end up being a personality match, have a backup plan, or consider setting up a household arrangement that keeps them separated for the long term. And if you’re adopting a pet, do your homework and ask its previous owners or shelter if it’s lived with other animals before, or gets along with them.

2. TRAIN YOUR DOG.

To set your dog up for success with cats, teach it to control its impulses, Sandor says. Does it leap across the kitchen when someone drops a cookie, or go on high alert when it sees a squeaky toy? If so, it probably won’t be great with cats right off the bat, since it will likely jump up whenever it spots a feline.

Hold off Fido's face time with Fluffy until the former is trained to stay put. And even then, keep a leash handy during the first several cat-dog meetings.

3. GIVE A CAT ITS OWN TERRITORY BEFORE IT MEETS A DOG.

Cats need a protected space—a “base camp” of sorts—that’s just theirs, Galaxy says. Make this refuge off-limits to the dog, but create safe spaces around the house, too. This way, the cat can confidently navigate shared territory without trouble from its canine sibling.

Since cats are natural climbers, Galaxy recommends taking advantage of your home’s vertical space. Buy tall cat trees, install shelves, or place a cat bed atop a bookcase. This allows your cat to observe the dog from a safe distance, or cross a room without touching the floor.

And while you’re at it, keep dogs away from the litter box. Cats should feel safe while doing their business, plus dogs sometimes (ew) like to snack on cat feces, a bad habit that can cause your pooch to contract intestinal parasites. These worms can cause a slew of health problems, including vomiting, diarrhea, weight loss, and anemia.

Baby gates work in a pinch, but since some dogs are escape artists, prepare for worst-case scenarios by keeping the litter box uncovered and in an open space. That way, the cat won’t be cornered and trapped mid-squat.

4. EXERCISE YOUR DOG'S BODY AND MIND.

“People exercise their dogs probably 20 percent of what they should really be doing,” Sandor says. “It’s really important that their energy is released somewhere else so that they have the ability to slow down their brains and really control themselves when they’re around kitties.”

Dogs also need lots of stimulation. Receiving it in a controlled manner makes them less likely to satisfy it by, say, chasing a cat. For this, Sandor recommends toys, herding-type activities, lure coursing, and high-intensity trick training.

“Instead of just taking a walk, stop and do a sit five times on every block,” she says. “And do direction changes three times on every block, or speed changes two times. It’s about unleashing their herding instincts and prey drive in an appropriate way.”

If you don’t have time for any of these activities, Zoe recommends hiring a dog walker, or enrolling in doggy daycare.

5. LET CATS AND DOGS FOLLOW THEIR NOSES.

In Galaxy's new book, Total Cat Mojo, he says it’s a smart idea to let cats and dogs sniff each other’s bedding and toys before a face-to-face introduction. This way, they can satisfy their curiosity and avoid potential turf battles.

6. PLAN THE FIRST CAT/DOG MEETING CAREFULLY.

Just like humans, cats and dogs have just one good chance to make a great first impression. Luckily, they both love food, which might ultimately help them love each other.

Schedule the first cat-dog meeting during mealtime, but keep the dog on a leash and both animals on opposite sides of a closed door. They won’t see each other, but they will smell each other while chowing down on their respective foods. They’ll begin to associate this smell with food, thus “making it a good thing,” Galaxy says.

Do this every mealtime for several weeks, before slowly introducing visual simulation. Continue feeding the cat and dog separately, but on either side of a dog gate or screen, before finally removing it all together. By this point, “they’re eating side-by-side, pretty much ignoring each other,” Galaxy says. For safety’s sake, continue keeping the dog on a leash until you’re confident it’s safe to take it off (and even then, exercise caution).

7. KEEP THEIR FOOD AND TOYS SEPARATE.

After you've successfully ingratiated the cat and dog using feeding exercises, keep their food bowls separate. “A cat will walk up to the dog bowl—either while the dog’s eating, or in the vicinity—and try to eat out of it,” Galaxy says. “The dog just goes to town on them. You can’t assume that your dog isn’t food-protective or resource-protective.”

To prevent these disastrous mealtime encounters, schedule regular mealtimes for your pets (no free feeding!) and place the bowls in separate areas of the house, or the cat’s dish up on a table or another high spot.

Also, keep a close eye on the cat’s toys—competition over toys can also prompt fighting. “Dogs tend to get really into catnip,” Galaxy says. “My dog loves catnip a whole lot more than my cats do.”

8. CONSIDER RAISING A DOG AND CAT TOGETHER (IF YOU CAN).

Socializing these animals at a young age can be easier than introducing them as adults—pups are easily trainable “sponges” that soak up new information and situations, Sandor says. Plus, dogs are less confident and smaller at this stage in life, allowing the cat to “assume its rightful position at the top of the hierarchy,” she adds.

Remain watchful, though, to ensure everything goes smoothly—especially when the dog hits its rambunctious “teenage” stage before becoming a full-grown dog.

10 Juicy Facts About Sea Apples

They're both gorgeous and grotesque. Sea apples, a type of marine invertebrate, have dazzling purple, yellow, and blue color schemes streaking across their bodies. But some of their habits are rather R-rated. Here’s what you should know about these weird little creatures.

1. THEY’RE SEA CUCUMBERS.

The world’s oceans are home to more than 1200 species of sea cucumber. Like sand dollars and starfish, sea cucumbers are echinoderms: brainless, spineless marine animals with skin-covered shells and a complex network of internal hydraulics that enables them to get around. Sea cucumbers can thrive in a range of oceanic habitats, from Arctic depths to tropical reefs. They're a fascinating group with colorful popular names, like the “burnt hot dog sea cucumber” (Holothuria edulis) and the sea pig (Scotoplanes globosa), a scavenger that’s been described as a “living vacuum cleaner.”

2. THEY'RE NATIVE TO THE WESTERN PACIFIC OCEAN.

Sea apples have oval-shaped bodies and belong to the genus Pseudocolochirus and genus Paracacumaria. The animals are indigenous to the western Pacific, where they can be found shuffling across the ocean floor in shallow, coastal waters. Many different types are kept in captivity, but two species, Pseudocolochirus violaceus and Pseudocolochirus axiologus, have proven especially popular with aquarium hobbyists. Both species reside along the coastlines of Australia and Southeast Asia.

3. THEY EAT WITH MUCUS-COVERED TENTACLES.

Sea cucumbers, the ocean's sanitation crew, eat by swallowing plankton, algae, and sandy detritus at one end of their bodies and then expelling clean, fresh sand out their other end. Sea apples use a different technique. A ring of mucus-covered tentacles around a sea apple's mouth snares floating bits of food, popping each bit into its mouth one at a time. In the process, the tentacles are covered with a fresh coat of sticky mucus, and the whole cycle repeats.

4. THEY’RE ACTIVE AT NIGHT.

Sea apples' waving appendages can look delicious to predatory fish, so the echinoderms minimize the risk of attracting unwanted attention by doing most of their feeding at night. When those tentacles aren’t in use, they’re retracted into the body.

5. THE MOVE ON TUBULAR FEET.

The rows of yellow protuberances running along the sides of this specimen are its feet. They allow sea apples to latch onto rocks and other hard surfaces while feeding. And if one of these feet gets severed, it can grow back.

6. SOME FISH HANG OUT IN SEA APPLES' BUTTS.

Sea apples are poisonous, but a few marine freeloaders capitalize on this very quality. Some small fish have evolved to live inside the invertebrates' digestive tracts, mooching off the sea apples' meals and using their bodies for shelter. In a gross twist of evolution, fish gain entry through the back door, an orifice called the cloaca. In addition expelling waste, the cloaca absorbs fresh oxygen, meaning that sea apples/cucumbers essentially breathe through their anuses.

7. WHEN THREATENED, SEA APPLES CAN EXPAND.

Most full-grown adult sea apples are around 3 to 8 inches long, but they can make themselves look twice as big if they need to escape a threat. By pulling extra water into their bodies, some can grow to the size of a volleyball, according to Advanced Aquarist. After puffing up, they can float on the current and away from danger. Some aquarists might mistake the robust display as a sign of optimum health, but it's usually a reaction to stress.

8. THEY CAN EXPEL THEIR OWN GUTS.

Sea apples use their vibrant appearance to broadcast that they’re packing a dangerous toxin. But to really scare off predators, they puke up some of their own innards. When an attacker gets too close, sea apples can expel various organs through their orifices, and some simultaneously unleash a cloud of the poison holothurin. In an aquarium, the holothurin doesn’t disperse as widely as it would in the sea, and it's been known to wipe out entire fish tanks.

9. SEA APPLES LAY TOXIC EGGS.

These invertebrates reproduce sexually; females release eggs that are later fertilized by clouds of sperm emitted by the males. As many saltwater aquarium keepers know all too well, sea apple eggs are not suitable fish snacks—because they’re poisonous. Scientists have observed that, in Pseudocolochirus violaceus at least, the eggs develop into small, barrel-shaped larvae within two weeks of fertilization.

10. THEY'RE NOT EASILY CONFUSED WITH THIS TREE SPECIES.

Syzgium grande is a coastal tree native to Southeast Asia whose informal name is "sea apple." When fully grown, they can stand more than 140 feet tall. Once a year, it produces attractive clusters of fuzzy white flowers and round green fruits, perhaps prompting its comparison to an apple tree.
