Hero Crayfish Cheats Death By Removing Its Own Claw to Escape Pot of Boiling Water

There remains a perpetual debate over the ethical consequences of taking a crustacean and boiling it alive. In early 2018, Switzerland actually made it illegal to give living lobsters a scalding hot bath. (Instead, chefs are expected to stun them electronically before submersion.) Scientists can’t reach a conclusion over whether decapods feel pain—or if we can even define what that means for them.

While humans argue, some clawed sacrifices are taking action. A crayfish filmed by a Facebook user in China is making the internet rounds and being hailed as a hero after taking dramatic measures to escape a boiling pot of water.

In the footage, the crayfish appears to be unable to extricate its left appendage from a bubbling vat of doom. Rather than succumb, the crayfish uses its right claw to sever its compromised claw and scurry off. At 11 seconds, it’s the best summary of a Saw film possible.

“Juike,” the user who originally posted the video to the Weibo social media site, says he has taken the crafty invertebrate home and put him in an aquarium as a pet. The tiny survivalist may even regrow his lost limb, as crawfish are able to do, although it might not reach its former size.

Crayfish are in inherent danger of being turned into soup in China, where specialty restaurants devoted to their preparation are popping up. Some observers believe their popularity is due to diners having to step away from phones and social media in order to use both hands to peel away at their shells.

It 'Rained' Spiders in Brazil Last Week—and You Can Watch It If You Dare

If recent events are anything to go by, you should be less concerned about swallowing spiders in your sleep and more concerned about bird-eating spiders raining down on your head. As The Guardian reports, recent footage from the Brazilian countryside shows thousands of spiders seemingly suspended in mid-air. (Arachnophobes might want to give the video below a miss.)

In reality, they aren’t falling at all. The spiders, which likely belong to a South American species called Parawixia bistriata, are merely crawling on an ultra-fine and nearly invisible web that attaches to two objects, like trees or bushes, to form a canopy.

So why do they do it? To catch prey, naturally. They’re likely to snag a variety of insects and maybe even small birds in their communal web, which can stretch up to 13 feet wide. (And yes, they eat the birds, too.)

Brazilian biology professor Adalberto dos Santos tells The Guardian that P. bistriata are some of the rare “social” spiders that do this. They leave their webs up overnight, hide out in the nearby vegetation, and then return at dawn to feast.

While this natural phenomenon is certainly unsettling, it isn’t exactly rare. Residents of the southeast municipality of Espírito Santo do Dourado, where the video was shot, said these “spider rains” are common when the weather is hot and humid.

Here’s another video from Santo Antônio da Platina in southern Brazil in 2013.

Other species of spider have been known to jump into the wind and "surf" on strands of silk as a means of getting around. They do this to escape threats or get to food or mates in other locations, and cases of "spider flight" have been recorded all over the world. Some especially adventurous spiders have even been known to cross oceans by “ballooning” their way from one land mass to the next.

The FDA has recalled several brands of dry dog food that contain potentially toxic levels of vitamin D, The Atlanta Journal-Constitution reports. While vitamin D is essential for dogs, too much of the nutrient can result in kidney failure and other serious health problems.

The FDA has already received reports of vitamin D toxicity in dogs that consumed certain dry foods. Pet owners are advised to stop using the following products:

Symptoms of vitamin D poisoning usually develop 12 to 36 hours after pets consume a suspect food, according to PetMD. The FDA says those symptoms include vomiting, loss of appetite, increased thirst, increased urination, excessive drooling, and weight loss. "Customers with dogs who have consumed this product and are exhibiting these symptoms should contact their veterinarian as soon as possible," the FDA writes.

The agency says the situation is still developing, and it will update the list of recalled brands as more information becomes available. According to WKRN News, veterinary professionals recommend sticking to dog foods that have an AAFCO label (from the Association of American Feed Control Officials) on them.
