Gnathostomulida is an entire phylum of microscopic worms that live buried beneath the seabed.

They have no circulatory or respiratory systems, but they do have a fearsome set of jaws for scraping bacteria, fungi and protists from grains of sand.

There are lots of worms that would be terrifying if they were a few metres bigger. Some of them would just cut you in half, but it looks like this one would scrape the flesh from your bones.

That’s why biodiversity is important.

Potoo and the descent into madness.

You wouldn’t think it to look at them, but they have a sweetly melancholic, bluesy call for attracting a mate that earns them the name Pour-me-one.

I doubt they’d even be allowed in a bar. They’d probably do something crazy like stab people with a bar stool because they remind him of his mother.

Four new species of carnivorous sponge!

All discovered by MBARI in mean-spirited, deep sea sites like hydrothermal vents, lava flows, cold seeps and atop dead volcanoes.

Most sponges eat bacteria they filter from the water, but these sickos are covered in microscopic hooks that cling onto any crustacean who gets too close.

Cells then migrate to the trapped prey, engulf it and digest it where it stands.

You know what it’s like when you see a thing with a backbone getting eaten by a thing without a backbone? Like a spider eating a bird or a mantis eating a frog. Well, this is the shrimp’s equivalent!

The many colours and patterns of Burton’s Legless Lizard (Lialis burtonis).

It’s the most widespread of all Australia’s reptiles, and is closely related to geckos of all things.

While geckos are the masters of fancy footwear, Burton’s Legless Lizard eschews such frippery and opts for no legs at all.

Also it’s a master predator who feeds on other lizards by ambushing them and suffocating them in its jaws.

In Australia, life is for the legless.

Did you know you can make gloves out of clams?

The clam in question is the Noble Sea Pen from the Mediterranean Sea.

It can reach up to 4 feet tall and keeps itself in place using some 20,000 fine, sticky threads.

The threads can be removed, cleaned up and woven into a fine, golden fabric known as byssus cloth or sea silk.

This stuff has been popular and extremely expensive for over 2,000 years. Very few people remember the craft of its manufacture these days, which is just as well since there aren’t as many Noble Sea Pens around as there used to be.

Still, it’s always nice to have an utterly unexpected source for fabric now that we’re all accustomed to silk coming from a caterpillar.

It’s the Nebulae of Flesh!

They’re corals glowing with incredible, fluorescent colours like interstellar dust clouds. All you have to do is shine the right kind of light on them!

They say we’re all made of star stuff; turns out some of us still look like it, too!

Check out the full gorgeous video by Daniel Stoupin.

I’m so glad to see Daniel’s videos go from strength to strength over the past few years. I first came across his photography in 2011 from an old blog carnival called Circus of the Spineless.

About a month later he put up his first video and I immediately tweeted it to Kevin Zelnio, who posted it on his Scientific American blog. It got a lot of views after that!

In the comments under his first video he said:

"Do I feel proud of making the movie? - I think so
Do I feel rewarded? - no way!
Unfortunately making movies is too time consuming, and I can’t afford another couple of months of unpaid more-than-full-time job; it causes only problems in real life, sorry, but a sequel is unlikely in the nearest future”

I’m so glad he managed to make it work!
