Boa Constrictors Form Hunting Parties and We’re Totally Fine with That

Scientists have observed Cuban boas lining up, suspending themselves from cave ceilings in a “curtain” of bodies, and waiting for their bat prey to fly through. A report on this never-before-seen behavior was published in the journal Animal Behavior and Cognition [PDF].

At 3 to 6 feet long, the Cuban boa (Chilabothrus angulifer) is a hefty customer, the largest in its genus and one of the biggest in the West Indies. It’s a skilled hunter both on the forest floor and the cave ceiling, dangling like a fanged party streamer and snapping passing fruit bats out of the air.

Cooperative hunting is not uncommon in nature. Wolves do it, as do dolphins, apes, some birds, crocodiles, and even a few species of fish. Snakes … not so much. Scientists have seen snakes hunting in the same place, at the same time, but it was sort of an every-snake-for-itself situation. (In that nightmare-inducing scene in Planet Earth 2, for instance, researchers viewed the snakes as coordinating, not cooperating.) Or so we thought.

Yet when researcher Vladimir Dinets of the University of Knoxville settled in near a sinkhole cave in Cuba's Desembarco del Granma National Park to watch the snakes’ nightly bat-feast, he noticed something unusual: The snakes seemed to be making room for one another.

For eight nights between sunset and dawn, an apparently fearless Dinets watched the cave’s nine snake inhabitants position themselves on the roof of the cave. His first thought was that each snake just had its own favorite or assigned spot on the ceiling.

But over time, he realized that they were rotating, each arriving snake filling in gaps in the curtain space to ensure maximum bat-flightpath coverage.

This wasn’t just a bunch of snakes hunting in the same place at the same time. This was a bunch of snakes hunting together. And it was working. The boas stuffed themselves with little furry bodies.

“It is possible that boas are not unique among snakes, and that coordinated hunting is not particularly rare,” Dinets writes in his paper. “This possibility suggests that at least some snakes are not the ‘solitary animals’ they are commonly considered to be, and that they are capable of high behavioral complexity required for such hunting.”

This is fine.

Maine Man Catches a Rare Cotton Candy Lobster—For the Second Time

Just three months after a cotton candy lobster was caught off the coast of Maine, another Maine resident has reeled in one of the rare, colorful creatures.

Kim Hartley told WMTW that her husband caught the cotton candy lobster off Cape Rosier in Penobscot Bay—and it’s not his first time. Four years ago, he caught another one, which he donated to an aquarium in Connecticut. While the Hartleys decide what to do with their pretty new foster pet, it’s relaxing in a crate on land.

Though the chances of finding a cotton candy lobster are supposedly one in 100 million, Maine seems to be crawling with the polychromatic crustaceans. Lucky the lobster gained quite a cult following on social media after being caught near Canada’s Grand Manan Island (close to the Canada-Maine border) last summer, and Portland restaurant Scales came across one during the same season. You can see a video of the discovery in Maine from last August below:

According to National Geographic, these lobsters’ cotton candy-colored shells could be the result of a genetic mutation, or they could be related to what they’re eating. Lobsters get their usual greenish-blue hue when crustacyanin—a protein they produce—combines with astaxanthin, a bright red carotenoid found in their diet. But if the lobsters aren’t eating their usual astaxanthin-rich fare like crabs and shrimp, the lack of pigment could give them a pastel appearance. It’s possible that the cotton candy lobsters have been relying on fishermen’s bait as their main food source, rather than finding their own.

While these vibrant specimens may look more beautiful than their dull-shelled relatives, even regular lobsters are cooler than you think—find out 25 fascinating facts about them here.

What’s Better Than a Dog in a Sweater? A Sweater That Shows an Image of Your Dog in a Sweater

If you think the sight of someone walking their sweater-clad dog is just about the cutest thing in the world, you’re absolutely correct. But what if that person was wearing a sweater that showed an image of their dog wearing a sweater? If you think that sounds even cuter, you’re in for a treat.

According to People, New York-based apparel company Sweater Hound will knit you a sweater that displays an image of your dog in a sweater—all you have to do is submit your favorite photo of your dog. And, because not all dogs love wearing sweaters in real life, your dog doesn’t have to be wearing a sweater in the photo you upload.

Each sweater is made from a combination of acrylic and recycled cotton, and will prove to your pet that you truly do love them more than anyone else (unless you already own sweaters emblazoned with the faces of your friends and family).

The sweaters, which cost $98 each, come in both child and adult sizes, and you can choose between cream, navy, black, and gray. The options don’t stop there—Sweater Hound offers sweaters that show your dog wearing just a bow tie, a bow tie and a sweater, a Santa hat and scarf, reindeer ears and a sweater, or even a “Super Dog” cape and domino mask outfit.

If sweaters aren’t really your style, there are also hoodies and sweatpants decorated with a smaller, logo-sized image of your dog. Or, you could snuggle with your prized pooch underneath a warm blanket bearing a rather giant image of said pooch.

While the company does specialize in creating dog-related products, they’ll do their best to accommodate people who love salamanders in Santa hats, birds in bow ties, and other pets wearing clothes. You can email them at Hello@Sweaterhound.com to discuss your options.

If you’re hoping to get someone a gift from Sweater Hound this holiday season, you should act fast: You have to place your order by December 4 in order to guarantee delivery before Christmas, and that date will likely change as the days go by.

Adorable, customizable clothing is just one of the many perks of being a dog owner—here are 10 more scientifically proven benefits.
