Hagfish Take Weeks to Recover from Sliming Someone

If you see a hagfish don’t anger it. Under attack, these bottom scavengers and hunters releases thick, clear slime in astonishing quantities. Potential predators back off quickly when presented with the slime, because it clogs their gills. The hagfish itself escape their own mucus that they tie their bodies into a knot and scrape it off (A highway in Oregon was harder to clean up after a truck full of hagfish crashed there last year.)

However, it turns out that this mucus is a precious resource for a hagfish. After sliming a predator, the fish can take nearly a month to refill its slime glands. So leave the poor slime monsters alone.

Wildlife is adjusting life in the big city

And I for one am wondering how the hell they do it! I just moved to a bigger city and I love it, but I’m finding my time a little stretched thin.

And I have opposable thumbs, and grocery stores. I can’t imagine how wildlife are doing it. Are they better at adulting than I am?

Read about how mountain lions are handling it here.

What Eats What: A Landlubber’s Guide to Deep Sea Dining

You’ll never go to dinner in the deep sea. It’s dark, vast and weird down there. If the pressure alone didn’t destroy your land-bound body, some hungry sea creature would probably try to eat you.

Fortunately for you, something else has spent a lot of time down there, helping to prepare this guide to deep sea dining.

For nearly three decades, robots with cameras deployed by the Monterey Bay Aquarium Research Institute have glided through the ocean off the coast of central California at depths as deep as two and half miles below.

The Crabbiest of Crabs

There’s a theory that giant crabs overwhelmed Amelia Earhart, dismembered her and carried her bones underground.

Speculative, at best. Sounds crazy, we know.

But so has almost every other horrifying rumor about the so-called coconut crabs — until science inevitably proves them true.

They grow to the size of dogs. They climb trees, and tear through solid matter with claws nearly as strong as a lion’s jaws.

And now we know what they eat (spoiler alert: basically anything they want).

Here. And watch the video…

 

When This Sea Slug Eats, It Prefers the Turducken of the Sea

I’ve been trying to figure out how to write about this for a few weeks. There is a new type of predation, practiced by sea slugs called “kleptopredation”.

These psychedelic slugs eat hyrdroids, and will pop polyps off the hydroid as one might pick flowers off a stalk. But a new paper suggests that sea slugs prefer to eat hydroids that have just caught plankton.

Think of it like a bear. You (a human) just caught some salmon while fishing in Alaska (I hear it’s the thing to do there). And said bear sees this and waits for you to eat your fish before swooping in to eat you both. It’s two meals for the price of one. A little human-salmon combo meal.

These sea slugs are doing the same thing. So as you head home for Thanksgiving, potentially to eat a turducken, think about how you might be practicing some kleptopredation your self. And if you want to know more, read about it here.

Birds Beware: Of the Praying Mantis?

“Tom Vaughan, a photographer then living in Colorado’s Mancos Valley, kept a hummingbird feeder outside his house. One morning, he stepped through the portico door and noticed a black-chinned hummingbird dangling from the side of the red plastic feeder like a stray Christmas ornament.

At first, Mr. Vaughan thought he knew what was going on. “I’d previously seen a hummingbird in a state of torpor,” he said, “when it was hanging straight down by its feet, regenerating its batteries, before dropping down and flying off.”

On closer inspection, Mr. Vaughan saw that the hummingbird was hanging not by its feet but by its head. And forget about jumping its batteries: the bird was in the grip of a three-inch-long green praying mantis.

The mantis was clinging with its back legs to the rim of the feeder, holding its feathered catch in its powerful, seemingly reverent front legs, and methodically chewing through the hummingbird’s skull to get at the nutritious brain tissue within.

“It was staring at me as it fed,” Mr. Vaughan said. “Of course, I took a picture of it.” Startled by the clicking shutter, the mantis dropped its partially decapitated meal, crawled under the feeder — and began menacing two hummingbirds on the other side.”

Tree-Eating Beetles March Northward, Lured by Milder Winters

For lovers of the stately pine forests of the Northeast, sightings of a destructive tree-eating beetle in recent years have been nothing short of alarming.

Now, new research from climatologists at Columbia University confirms what ecologists feared: Warmer winters mean the southern pine beetle is here to stay, and is set to march ever northward as temperatures rise.

Historically, the tiny beetles, which starve evergreens to death, were largely unheard-of north of Delaware. The Northeast’s cold winters killed off any intruders.

The winters are no longer cold enough.
