Flatworms inject sperm into their heads to self-fertilize

When alone, a hermaphroditic flatworm is known to stab itself with its needle-tipped penis and inject sperm to self-impregnate. It's called "hypodermic insemination."

Thousands of worms found in neat piles on road

Texas Floods: Piles of Worms Mysteriously Show Up Along Roads Credit: Eisenhower State Park - Texas Parks and Wildlife/ Facebook Piled neatly by road markings in Eisenhower State Park, Texas, a vast number of gently writhing worms grace the asphalt. At first mistaken for spaghetti by rangers baffled at their regularity, it soon became clear something stranger was afoot.

Seen in photos posted to Facebook by staff from Texas Parks & Wildlife Department, the mystery has baffled biologists, ABC News reports. But two theories are emerging:

Park officials have two theories about the worms’ bizarre behaviour.

The first is that the ground become so wet that the worms were forced to move to the dryer parts. The second is that rain may sound like predators, so the worms moved and clumped together to avoid them.

My hypothesis: escaped gnomes put there there.

Discovery of worm neuron that senses Earth's magnetic field

Worms have a specific antenna-shaped neuron that senses the Earth's magnetic field, enabling the transparent nematode to know up from down when it's in the ground.

"Monster worm" found in Vietnam

Paul held himself apart from the humor, his attention focused on the projection and the question that filled his mind: "Thufir, are there sandworms big enough to swallow that whole?"

Silence settled on the table. The Duke cursed under his breath, then thought: No—they have to face the realities here.

"There’re worms in the deep desert could take this entire factory in one gulp," Thufir said.

Worms a delicacy in Zimbabwe

Are these the remains of ancient worm holes?

Here's a weird, great geological feature I spotted yesterday while out hiking in rural Oklahoma. We were out in a flat, flat plan that was dotted with a few tall, angular sandstone mounds and narrow sandstone canyons carved out by erosion. This rock was sticking out of the side of one of the mounds. It was the only place we saw anything like these vertical, tube-like structures, which stretched from the ground up to probably about my shoulder.

When I posted this image on Twitter yesterday, several people suggested that the tubes might be skolithos — tube-shaped fossils that were probably made by some kind of ancient worm creature and turn up sometimes in sandstones. While the pictures on Wikipedia don't look very similar to what I saw, there are apparently lots of different forms these things (and similar tube fossils) can take.
