The Bestiary: Scaly-Foot Gastropod

These are diamond-tipped indenter heads. They are used to inflict ludicrous pressure upon various shit in order to measure the hardness of said shit. Recently, one of these was used to measure the hardness of a certain animal’s shell, and, instead of crushing the ever-loving fuck out of it, it found serious resistance.

The aforementioned animal is a snail.

Let me spell this out for ya. There is a snail that can resist the onslaught from an industrial-grade diamond applied with the pressure of several metric fucktonnes. A. Snail. That. Can. Resist. A. Diamond. Indenter.

Just imagine stepping on one of these guys. Instead of breaking their shells like those of usual snails, you’d break your own fucking ankle.

Jesus trilobitic Christ.

Today’s Episode: the Scaly-Foot Gastropod

Just look at this little piece of shit. Look at it and say to my face it doesn’t look like a tank.

What we’ve got here is the rather lamely-named scaly-foot gastropod, also known by the considerably more badass-sounding names of iron snail and  Chrysomallon squamiferum. The SFG hails from the deep-sea thermal vents known as black smokers, deep-sea vents from which water gushes constantly. That water, by the way, originates from below the mantle.

The proximities of black smokers are perfectly lightless, unforgiving badlands, with water rich enough in poisonous sulphuric chemicals to perform the chemical equivalent of curbstomping on any “superior” lifeform that dares stick it’s overspecialized, prissy ass down there, heat up to 450 degrees Celsius (one thirteenth of the temperature of the Sun’s surface) and pressures that could turn any land-dwelling scum into a Flatlander within seconds. If creatures want to survive here, they must either be hyper-effective murder-machines, or damn nigh unkillable.

The SFG’s predators, such as venomous, killer cone snails with bionic harpoon guns evolved from their own “teeth”, and car-wrecking carnivorous crabs that kill snails by pressing down on their shells for days with jagged ultra-hard pincers specifically designed to do this belong in the first category.

The SFG itself belongs in the second.

Hoooly shit does it ever.

The unkillability itself is obtained by using the chemosynthetic bacteria lurking in its glands to absorb and mineralize the poisonous iron-sulphides the water is overabundant with, making them non-poisonous for the snail. It then coats its shell with the minerals, constructing an unique three-layer structure no other gastropods possess. None.

To sum it up, the outer layer, used to block the bulk of the attack, is made up of greigite (Fe3S4), a ridiculously hard mineral. Then comes a middle layer of squishy organic matter purposed to absorb the shock of impacts, dents and blows. Finally, an inner layer of aragonite (CaCO3), designed to prevent asshole crabs from sticking their nasty claws into the shell and picking it apart splinter by splinter.

How effective is it? Well, this armor is so much better than what we puny humans possess that the U.S. Army is actively conducting research about it with the hope of developing new armor using the same build. Yes, this shell is so unbreakable that it caused the a military to lose their heads over a goddamn sea snail. Go figure.

Also, according to biologists researching the SFG, if we covered oil pipes with the stuff, they could easily shrug off damage done by such trivial things as fucking icebergs,

Not bad from a snail, I say.

But that’s not all! Look at it again.

There is a reason it’s called Scaly-foot Gastropod.

Those are scales. Made out of iron minerals.

Iron minerals that are poisonous and magnetic.

The scales are there because of the tooth-harpoon-hurling killer snails. Namely, they serve to deflect the harpoons entirely. Deflective iron scales. On a snail.

Holy crap.

So let’s sum it up, shall we? There exists a snail that forges itself a magnetic armor made out of poisonous iron ore to fend off killer crabs and venomous sniper snails that hunt it in its habitat of a vent leading to the Earth’s mantle.

Oh, and they don’t really eat anything, relying on their chemosynthetic bacteria for sustenance instead. In layman’s terms, that means that the snail keeps itself running by oxidating the sulphides in the water, all of which are lethally poisonous to most lifeforms, including the snail itself. The only reason it survives is that the bacteria chemosynthetize the sulphides, enabling the snail to quite literally live off of poison.

This molluscoid tank is ridiculously metal in more ways than one.

The tiniest of traveling companions: Here, a small school of fish (and even a tiny shrimp!) hitch a ride through the blue with a jellyfish in Gray’s Reef National Marine Sanctuary.

 Some juvenile fish can live amidst a jelly’s tentacles without being harmed. In doing so, they gain protection from predators and the opportunity to feed on the jelly’s leftovers. Plus, they gain a new buddy to swim with!

“You exorcised it, Reigen,” Dimple said. “I told you before. You’re a real psychic now.”

The spirit was saying something else now, but Reigen couldn’t hear him over the sudden roar of blood in his ears. He looked down at his shaking fingers. The aura remained, rising slowly off of him in slow tendrils of smoke. There had to be some other explanation. Reigen was not a psychic. There was no possible way he had any sort of power, and certainly not enough power to banish a spirit of that caliber.

And then a thought appeared. It was a strange, all consuming thought, one that Reigen recognized as not his. Everything else in his mind became black static.

you are not my host.

hello friends. over christmas break, i wrote a multi-chapter mob psycho 100 au fic called symbiosis.

after fighting Claw’s Seventh Division (the end of the first season of the anime), Mob’s powers leave Reigen, but something is left behind- something undefinable. Reigen realizes something is wrong, but doesn’t know what, until something- that is, ???%- begins talking to him. Meanwhile, someone begins to take notice of the strange psychic activity coming from the Spirits and Such Consultation office.

If you enjoy plot centric AUs involving psychic powers, horror elements, and general twists and turns, check it out! it’s pretty good.

Torterra practically has a whole ecosystem on its back. It grows trees, moss, and bushes; small pokémon build nests and sometimes spend their whole lifetimes on Torterra’s back. According to the pokédex, herds of Torterra are mistaken for “moving forests”, and that’s fairly accurate.

So how, and why, does Torterra do this? A close relationship between species, like the organisms thriving on Torterra’s back, is known as symbiosis. This kind of relationship benefits at least one of the species involved. 

Sloths in our world have a relationship similar to Torterra’s. Sloth fur is long, thick, coarse, and slow-moving, making it an ideal environment for species to live. Algae, fungi, moths, beetles, and cockroaches all commonly make their homes in the fur of a sloth. 

The sloth gains the benefit of camouflage: the green color of the algae and fungus help it hide among the trees that it lives in. The small organisms get shelter, water, and safety. 

The interesting thing is that the type of algae that grows on sloths, Trichophilus welckeri, only grows on sloths. This algae is not found anywhere else in nature besides on sloths’ backs. Biologists theorize that this is because this algae needed that kind of environment to evolve and grow: the sloth and the algae evolved together.

This fits Torterra rather well; the plants on his back grow starting on young Turtwigs. It may very well be that the plants and trees on Torterra’s back are only found on Torterra’s back. They have a co-evolutionary relationship like the sloth and the algae.

The tree benefits by getting nutrients and water from Torterra, and it also no doubt helps transport the tree’s seeds around, particularly to other turtwig. The fact that Torterra moves also might be beneficial to the plants: it doesn’t have to worry about dry seasons or cold seasons, since Torterra would migrate to avoid those, too. 

Torterra, in turn, gains camouflage. It also gains an easy food source: tortoises are herbivores, and so if they can’t find food elsewhere there’s always a supply on their backs.

The small pokémon that live on Torterra gain shelter, protection, and food from the small ecosystem. They might help Torterra by eating pests or parasites, or by helping the natural processes that make the tree grow well.

In any case, it seems to be a good situation for most if not all of the pokémon involved. The giant Torterra hosts a variety of plants and animals on its back.

Torterra has symbiotic relationships with all of the plants and animals that live on its back. Torterra benefits from camouflage and food, and the rest gain shelter and protection.

This is one of the most bizarre wildlife photos I have ever seen! This is a wild macaque riding a sika deer!

In the words of Primatologist Cédric Sueur: “My favorite behavior is that of a macaque riding on the backs of Sika deer. There is a close cooperation between macaques and deer on Yakushima island. The deer eat seeds dropped by macaques on the ground, as well as their feces. Macaques may groom the deer for parasites such as lice, which are rich in proteins. At times, macaques will climb on the back of a deer for transportation. They don’t travel the kinds of distances humans do on horseback, but the similarity is there.”

I just thought of something: Problematic Mochizuki Meiko and the (Equally) Problematic 02 Ending

I read somewhere that the writers of Tri. don’t plan to change the ending of 02. Meaning that particular ending is going to be as canon as Kataang is to the Zutara supporters Avatar fans. But seeing that Mochizuki is not featured in that ending, I wonder if the writers are going to go down one of the following routes:

1) They’re going to make her tragically die. I don’t mean it in a sinister sense. Sure I find Mochizuki annoying more often than not, but I don’t hate her enough that I want her to die in my favourite nostalgia anime. It is rather drastic to have a character death. I’m saying this because it would seem like something the Tri. writers are capable of doing. What with me bathing in Takeru’s tears and not!Gennai’s tongue action and Ophanimon FD on the Kyousei poster and no HD poster and/or confirmed release date after almost a month. Yeah, I’m pretty sure they feel like God now.

2) They’re going to make her fit somehow. Perhaps by having Mochizuki return to Tottori, thus not remaining in contact with the original Chosen as often and not being well informed of the day these kids decided to pose for the 02 ending shooting day.

3) They’re going to make her fit by remaking the ending scene somehow. Mochizuki could appear along with the Chosen Children in the digital world, along with a child of her own. Heck, the writers could be confirming theories about her being married to one of the boys! And maybe, just maybe, only then we can get an itsy bitsy explanation as to why Takeru the unreliable narrator decided to omit having a visual reference to Hikari being his wife a kindergarten teacher. 

Shit I'd like to see in Symbiosis

–More I sight pertaining to the kind of relationship Gatomon and Kari had before the reboot, and how it differs from the one they’re developing now.

–Situations that his light just how different Gatomon is now that her traumatic past had been erased.

–Character growth for Kari; I’d like to see her act independently and save someone else for a change.


–Wizardmon remembering Gatomon and confronting the fact that she’s forgotten him.

–Kari and Wizardmon talking/reminiscing about the old Gatomon.

–Dark Gennai getting bitch slapped some more.

–Old Reliable Joe Badass

–ANY mention of the 02 kids.


First of all… Yes I am one of those very special people and have acknowledged my own skills in the field of drawing funny lines and circles. So let’s start with what I like to call: WTF is happening in this poster?

There’s been much speculation about the poster already and now I want to get in and hopefully raise some valid questions and not just make a fool of myself! So yeah, it’s more like please tell me what these things are than me actually saying anything smart about the pic

So that tail or whatever​ lined with yellow… What the hell is that thing? First I thought it belonged to either Ophanimon FDM or Meistachemon (could still belong to it) but then I noticed that it looks to have a head (or a larger portion of something) behind Stachey. This one I won’t address so much, because I’m fairly certain my tired brain wants to make it into some dragon Digimon and it actually is part of Meicoomon’s Ultimate form. But just gonna point out that it doesn’t look like a fitting additional part for either of the Digimon’s.

Then the white one!! Yes… I know I should wait for the HQ poster, but when you’re obsessed… Anyway it’s a thing in front of Hikari that’s different shade of blue than Ophanimon​ and I thought it looked peculiar. I can’t really say for sure what it is but this will be my #1 question till we get the damn HQ poster. And at some point I thought maybe Hikari was looking at it (?)

The blue one… Looks like a wishbone, I honestly forgot why I circled it…

But yeah, non marked questions include:
- That weird black shredded cloth looking thingy in the lower mid-section of Ophanimon’s schyte
- What is Meiko holding?
- Hikari, why u sad?
