5 Flashy Facts About Peacock Spiders

They’re fuzzy, they’re flashy, and they’ve got great moves. 

1. They’re small, but they’re scrappy. 

Peacock spiders (genus Maratus) cram a whole lot of swagger into a teeny-tiny package. The biggest Maratus species can reach 0.3 inches—about the size of a pencil eraser.

Like almost all spiders, peacock spiders are venomous. But that doesn’t mean they’re dangerous to humans: Their little jaws are so tiny that they couldn’t even puncture our skin.

 We’re safe, but crickets and other spiders are not. Like all jumping spiders, the peacock spiders don’t build webs. They stalk their prey like lions. When the time comes, they pounce, and can take down prey three or four times their size. 

2. Each species has its own dance—and house mix. 

Female peacock spiders are the Tina Belchers of the animal kingdom. To impress them, you need two things: a terrific butt, and a talent for shaking it.

To fulfill these requirements, male peacock spiders have evolved spectacular iridescent fans on their butts, and fancy dances to show them off. The dance of each species is unique, but most of them involve sensual leg waving and booty shaking.

As if that wasn’t enough, a male also periodically pauses his dance to drum on the ground, and occasionally on the female’s head. Spiders don’t have ears like we do, and instead hear through organs on their legs. The drumbeats’ vibrations travel across the ground and up the legs of the female, which is apparently super-hot. If the male’s little vaudeville routine is satisfactory, the spiders get down to business.

3. It's bad for the male if his dancing isn't up to par.  

Male spiders aren’t just dancing for sex; they’re dancing for their lives. Courtship is risky business for the males, since female peacock spiders will not hesitate to eat their suitors. But here’s the thing: they only seem to eat the bad dancers. How’s that for incentive?  

4. The babies are SO CUTE. 

Unexpected bonus: peacock spider spiderlings are ridiculously adorable.

After mating, Maratus mothers lay about a half-dozen eggs. (I don’t know if you remember Charlotte’s Web, but for spiders, six eggs is nothing.) With touching dedication, a female peacock spider guards her eggs for two weeks without eating, which often means her end. But when those two weeks are up, the little critters emerge, and boy, are they worth it. Look at that face! They’re like Ewoks with extra eyes!  

5. The two newest species are Sparklemuffin and Skeletorus.

Biologist Madeline Girard and her friend Eddie Aloise King were on a collecting mission in Queensland, Australia, scanning the ground for specimens of Maratus volans. Instead, they found two entirely new species.

Male Sparklemuffin (Maratus jactacus) spiders have butts like ski caps made out of jewels and a dance that makes them look very, very drunk.

The black and white Skeletorus (Maratus sceletus) was named after Skeletor from Masters of the Universe, and looks very different from any other peacock spider, which might mean the group is more diverse than scientists suspected. “I’ve always been fascinated by things that go unnoticed,” Girard tells mental_floss.

Watch This Live Stream to See Two Rare Penguin Chicks Hatch From Their Eggs

Bringing an African penguin chick into the world is an involved process, with both penguin parents taking turns incubating the egg. Now, over a month since they were laid, two penguin eggs at the National Aviary in Pittsburgh, Pennsylvania are ready to hatch. As Gizmodo reports, the baby birds will make their grand debut live for the world to see on the zoo's website.

The live stream follows couple Sidney and Bette in their nest, waiting for their young to emerge. The first egg was laid November 7 and is expected to hatch between December 14 and 18. The second, laid November 11, should hatch between December 18 and 22.

"We are thrilled to give the public this inside view of the arrival of these rare chicks," National Aviary executive director Cheryl Tracy said in a statement. "This is an important opportunity to raise awareness of a critically endangered species that is in rapid decline in the wild, and to learn about the work that the National Aviary is doing to care for and propagate African penguins."

African penguins are endangered, with less than 25,000 pairs left in the wild today. The National Aviary, the only independent indoor nonprofit aviary in the U.S., works to conserve threatened populations and raise awareness of them with bird breeding programs and educational campaigns.

After Sidney and Bette's new chicks are born, they will care for them in the nest for their first three weeks of life. The two penguins are parenting pros at this point: The monogamous couple has already hatched and raised three sets of chicks together.

Bleat Along to Classic Holiday Tunes With This Goat Christmas Album

Feeling a little Grinchy this month? The Sweden branch of ActionAid, an international charity dedicated to fighting global poverty, wants to goat—errr ... goad—you into the Christmas spirit with their animal-focused holiday album: All I Want for Christmas is a Goat.

Fittingly, it features the shriek-filled vocal stylings of a group of festive farm animals bleating out classics like “Jingle Bells,” “Rudolph the Red-Nosed Reindeer,” and “O Come All Ye Faithful.” The recording may sound like a silly novelty release, but there's a serious cause behind it: It’s intended to remind listeners how the animals benefit impoverished communities. Goats can live in arid nations that are too dry for farming, and they provide their owners with milk and wool. In fact, the only thing they can't seem to do is, well, sing. 

You can purchase All I Want for Christmas is a Goat on iTunes and Spotify, or listen to a few songs from its eight-track selection below.
