House Centipedes Use Their Legs Like Lassos to Catch Prey

You thought house centipedes were already creepy enough without needing to know the graphic details of how they catch and kill their prey. But in case you were wondering, they sometimes use their legs like lassos to rope in and restrain their victims, London-based paleontologist Greg Edgecombe tells Deep Look, a web series created by KQED San Francisco and presented by PBS Digital Studios. That's not the only way they use their legs, either. “Basically arthropods are Swiss army knives,” Edgecombe says. “They differentiate the legs for different functions.”

In addition to using their flexible legs to put their prey in a triangle choke like an agile MMA fighter, they may even use their long hind legs in mating rituals. Their back legs contain as many sensory hairs as their antennae, and the two parts are often confused because they are similar in both length and appearance. Researchers say centipedes do a kind of ritual courtship dance in which the male and female arthropods raise and lower their back legs and antennae. There’s also some “mutual tapping and probing” involved.

The insects are cannibalistic, venomous, and exceptionally fast runners—but don’t worry, they rarely bite humans. Their long fangs, known as forciples, are actually modified legs. The forciples are not only used to hold their defenseless prey in place and inject venom, but also to clean and lubricate the sensory hairs along their legs.

By the way, despite popular belief, centipedes usually don’t have 100 legs. Most species have fewer than 60, and baby centipedes only have eight. As they grow, they develop more and more legs.

100 Dachshunds Competed in Cincinnati’s Annual ‘Running of the Wieners’

Every year, to kick off Cincinnati’s Oktoberfest Zinzinnati, 100 dachshunds compete in heats to decide who the fastest dachshund in the Midwest is. This year marks the 43rd annual Oktoberfest—one of the biggest Oktoberfest celebrations outside of Germany (more than 500,000 people attend the three-day event).

On the afternoon of Thursday, September 19, 100 wiener dogs (and their owners and handlers) gathered in downtown Cincinnati for the 2019 "Running of the Wieners." The dogs, dressed in hot dog costumes, ran 10 heats, which lasted 75 feet or five seconds each. The winner of each heat advanced to the final round, where the top three finishers were decided.

Maple, a long-haired, one-year-old dachshund, ran his way into first place—and into our hearts.

Maple’s owner, Jake Sander, told WCPO that Maple is one of five dachshunds in the family, and that he learned to run fast by chasing his brother around. Leo and Bucky, two other doxies, placed second and third, respectively.

Besides the Running of the Wieners, Zinzinnati also hosts the World’s Largest Chicken Dance. However, the wiener dogs are more fun to watch.

Photographer Captures Polka-Dotted Zebra Foal in Kenya

Zebras are known for their eye-catching patterns, but this polka-dotted foal recently photographed in Kenya's Masai Mara National Reserve really stands out from the herd. As National Geographic reports, the zebra baby likely has pseudomelanism, a rare pigment condition that's been observed in the wild just a handful of times.

Nature photographer Frank Liu saw the zebra foal while looking for rhinos in the savannah wilderness preserve. After initially confusing the specimen for a different type of animal, he realized upon closer inspection that it was actually a plains zebra born with spots instead of stripes. The newborn foal was named Tira after the Maasai guide Antony Tira who first pointed him out.

A typical zebra pattern is the result of pigment cells called melanocytes, which are responsible for the black base coat, and melanin, which gives the animal its white stripes. (So if you've ever wondered if zebras are white with black stripes or black with white stripes, the answer is the latter). In Tira and other zebras with pseudomelanism, the melanocytes are fully expressed, but a genetic mutation causes the melanin to appear as dots rather than unbroken stripes.

Though rare, this isn't the only time a zebra with pseudomelanism has been documented in nature. Pseudomelanistic zebras have also been spotted in Botswana’s Okavango Delta, but Liu believes this could be the first time one was found in the Masai Mara preserve.

Zebra stripes aren't just for decoration. The distinct pattern may act as camouflage, bug repellant, and a built-in temperature regulation system. Without these evolutionary benefits, Tira has a lower chance of making it to adulthood: Pseudomelanistic zebra adults are rarely observed for this reason. But as Liu's photographs show, the foal has the protection and acceptance of his herd on his side.
