How You Can Help Animals Affected by Hurricane Florence

If you've ever considered rescuing a pet, now's the time to take the plunge: You could save an animal's life if you choose to adopt from a shelter in the path of Hurricane Florence.

With the Category 1 storm making landfall over the Carolinas this week, government officials have urged as many as 1.7 million residents to evacuate their homes. As a result, local animal shelters are scrambling to find homes for abandoned pets before the worst of the storm hits, and if they aren't able to place them in time, some animals will have to be euthanized.

That makes now the perfect time to adopt a pet if you're in the position to do so. Some shelters, like the Pender County Animal Shelter in Burgaw, North Carolina, have even waived their adoption fees in an effort to encourage more people to take pets home.

If you can't make a commitment to owning a pet at this time, fostering is also an option. Most shelters in the storm path will gladly place pets with someone who can give a dog or cat shelter until it's safe for them to return to the area. And if that's still not a possibility for you, you can help shelters by making a monetary donation. Transporting pets and making sure they're spayed, neutered, and vaccinated costs money, and shelters can use donations to help more pets get out the door and into safe homes.

The Charleston Animal Society, the Greenville Humane Society, the Humane Society of Charlotte, and the Pender County Animal Shelter are just a handful of animal shelters in need of assistance. You can also look at specific requests for support local shelters have made through this website.

Some Fish Eggs Can Hatch After Being Pooped Out by Swans

A question that’s often baffled scientists is how certain species of fish can sometimes appear—and even proliferate—in isolated bodies of water not previously known to harbor them. A new study has demonstrated that the most unlikely explanation might actually be correct: It’s possible they fell from the sky.

Specifically, from the rear end of a swan.

A study in the journal Ecology by researchers at the Unisinos University in Brazil found that killifish eggs can, in rare cases, survive being swallowed by swans, enduring a journey through their digestive tracts before being excreted out. This kind of fecal public transportation system explains how killifish can pop up in ponds, flood waters, and other water bodies that would seem an unlikely place for species to suddenly appear.

After discovering that some plants could survive being ingested and then flourish in swan poop, researchers took notice of a killifish egg present in a frozen fecal sample. They set about mixing two species of killifish eggs into the food supply of coscoroba swans living in a zoo. After waiting a day, they collected the poop and dug in looking for the eggs.

Of the 650 eggs they estimated to have been ingested by the swans, about five were left intact. Of those, three continued to develop. Two died of a fungal infection, but one survived, enduring 30 hours in the gut and hatching 49 days after being excreted.

Because killifish eggs have a thick outer membrane, or chorion, they stand a chance of coming through the digestive tract of an animal intact. Not all of what a swan ingests will be absorbed; their stomachs are built to extract nutrients quickly and get rid of the whatever's left so the birds can eat again. In rare cases, that can mean an egg that can go on to prosper.

Not all fish eggs are so durable, and not all fish are quite like the killifish. Dubbed the "most extreme" fish on Earth by the BBC, killifish have adapted to popping up in strange environments where water may eventually dry up. They typically live for a year and deposit eggs that can survive in soil, delaying their development until conditions—say, not being inside a swan—are optimal. One species, the mangrove killifish, can even breathe through its skin. When water recedes, they can survive on land for over two months, waddling on their bellies or using their tails to "jump" and eat insects. A fish that can survive on dry land probably doesn't sweat having to live in poop.

The researchers plan to study carp eggs next to see if they, too, can go through a lot of crap to get to where they’re going.

Sharks are some of the world's most intimidating creatures, right down to their species names. There’s the hammerhead shark, the great white shark, the bull shark—but did you know there’s also a cookiecutter shark? Don’t be fooled by its name, though: Mental Floss editor-in-chief Erin McCarthy says that the cookiecutter shark often preys on animals many times its size, and isn’t afraid to take a chunk out of a human. (And how they take a bite out of something is even more terrifying/fascinating.)

In this week’s edition of The List Show, Erin gives the lowdown on 31 amazing shark-related facts, including details on some Icelandic delicacies that even Anthony Bourdain found disgusting to trivia about Peter Benchley's Jaws.
