Do you have cool velvet worm facts? They're my favourite bug-creatures :3
I love velvet worms! Absolutely bizarre creatures. They don't have an exoskeleton and they move by changing the fluid pressure in their body. ALSO there's a species (Euperipatoides rowelli) that lives in social groups lead by a dominant female.
Let's admire that species.

Phylum #16: Onychophora, the velvet worms!
"Lobopods", unarmored relatives of arthropods, have a long and rich history. While early forms like Hallucigenia remain unclear as to their affinities, another lineage had already split from the first arthropods. Velvet worms still thrive today, having left the seas for rainforests and humid crevices.
Instead of the arthropods' articulated exoskeletons, velvet worms kept a softer, unarticulated cuticle, with tiny round "papillae" covered in bristles and scales providing their velvet-like appearance. They still moult their cuticle regularily, but do not gain new legs doing so - the babies already look like miniature adults!
Adapted to many terrains thanks to their flexible body and clawed legs, velvet worms are true ambush predators. They come with a special weapon: a glue-like slime, immobilizing prey and repelling predators, shot from appendages on each side of their mouth.
Velvet worms are also intelligent, social creatures. At least one species, Euperipatoides rowelli, is known for hunting together, living in groups of up to 15 individuals with complex interactions establishing their social hierarchy. Individuals within a group are often closely related, with most species giving live birth and taking care of their young!

Still a wip, but I anthropomorphised my velvet worm sona... Still thinking of a name for her. She's a cross between a Euperipatoides rowelli and an Ooperipatus silvanus!

Pls tell me about velvet worms <3
A velvet worm is one of the only known cousins of the water bear (if you know what that is). It’s scientific name “onychophora” means hooked feet because like the water bear and its other family ancestor Hallugenia (that weird thing from the Cambrian period)
They only live in tropical areas around the globe because they they moisture to survive. They are predatory animals attack their prey and defend themselves with this glue type substance that is actually like a non Newtonian fluid. It comes out as a fluid but rapidly turns into a sticky mess once it hits something.
Velvet worms come in two main flavors Peripatos and Peripatidae which describe their physiology as well as their distribution.
Some species are known to be social like the Euperipatoides genus. All in all really pretty to stare at, actually hard to rear so they aren’t really in the pet trade fingers crossed 🤞 .
Their biggest threat is habitat loss, but some species manage to survive in urban gardens and areas.
Most of the info is from the top of my head, but here is a website with experts.

We detected a strict female-dominated feeding hierarchy: the first individual to feed was always a female, and she remained the sole feeder for 45–60 min (Fig. 2).
This female fed in bouts of up to 10 min, interrupted by short intervals during which she moved around the Petri dish. During her solitary feeding time, males and young of the group remained distant, often in physical contact with one another.
The other females assumed a ‘waiting’ position close to the prey, circled it, and occasionally tried to feed. If noticed by the first female, they were attacked by her, bitten, kicked and pushed away.
After 45–60 min, the first female tolerated other individuals at the food. Now, the remaining females started feeding in groups, soon followed by the males and young (Fig. 2). The number of feeding males reached its maximum once the females started leaving the food.
All individuals eventually fed, but rarely all simultaneously. After 3 h, feeding was over, and the group reaggregated once the individuals had cleaned their mouthparts and antennae.

Science Fact Friday: These really weird not-worm worms.
I just learned about these little critters this week and HAD to do a Science Fact Friday on them.
Additional fact I couldn’t fit in: Some species of velvet worms lay eggs. Other species birth live young, either by storing eggs inside their bodies that hatch shortly before birth (ovoviviparity) or via actual in-uterus placental development (viviparity).
Evolution pls stop you’re being ridiculous

Cap-IM Rec Week 2021 - Multiverse Monday
Day 1 of the @cap-ironman Rec Week 2021. (Avengers Assemble! Noir! Super Hero Squad! Iron Man: Armoured Adventures! Contest of Champions! Ults! Travel the multiverse with your recommendations.)
... A little late 😅 but here are some of my favourite fics from different universes. (Mostly Ults...)
[Recs below the cut because there's a lot of them]
~
My Heart Would Benefit From a Little Tenderness From Time to Time by SuperstringSymphony
Rating: Teens and Up
Universe: Ultimates
Warnings: Mentions of Cancer
Summery: “Come with me.” Tony licks his lips, blue eyes lifting to meet Steve's. “We've both had a long week, I thought you might like to relax.” Tony's gaze darts from side to side. Steve has noticed since they started this that Tony only ever truly looks nervous when he's talking to him. “The car is around the front, what do you say, weekend getaway?” Tony smiles, stroking a hand down his back with a featherlight touch. Steve just barely represses a shiver, eyeing Tony for a moment. With other people he's always a little shuttered. Here though, with Steve, his expression is unguarded, eyes bright with hope. He looks a little strained though, as if the week has taken its toll on him as well.
Rec Comment: I love the softness of this story. Just Steve and Tony being domestic and sweet together.
~

Rating: Teens and Up
Universe: Ultimates
Warnings: None
Summery: Steve's not used to anyone spoiling him. But he's willing to let Tony try.

~
rushing head long by Red (S_Hylor)
Rating: Explicit
Universe: Ultimates
Warnings: Sexual Content
Summery: Sometimes things get said accidentally in the heat of the moment.

His Best Suit by ashes0909, FestiveFerret, SirSapling
Rating: Teens and Up

all of these precious things by Red (S_Hylor), SirSapling
Rating: Mature
Universe: Ultimates
Warnings: Temporary Character Death, Presumed Dead, Mpreg, Terminal Illnesses, Mentions of Cancer
Summery: There's Tony, and then there's Anthony. They go together, and Tony wouldn't change it, even if he knows that Anthony is going to kill him one day.
Then there's Steve, and Tony doesn't expect to be loved, never expects that he'll be put in the situation of having someone to leave behind.
But it's not him who disappears.
Rec Comment: Super angsty fic with Tony’s gem son Anthony, so much wonderful hurt. And the ending is delightfully hopeful.
~
Emergency Contact by valdomarx
Rating: Explicit
Universe: Ultimates
Warnings: Dubious Consent, Sex Pollen, Homophobic Language, Consent Issues
Summery: Steve has been exposed to sex pollen, and for some reason Tony is the person who's been called in to assist him.
Tony knows that he can't take advantage of Steve in this desperate state, but it's awfully hard to remember that when Steve is rubbing up against him and describing all of his deepest fantasies in excruciating detail.
Rec Comment: Great sex pollen fic, I always enjoy re-reading it.
~
Over Easy by Sineala
Rating: Explicit
Universe: Ultimates
Warnings: Sexual Content
Summery: After the death of Spider-Man, it's Tony rather than Fury who comes to try to fetch Steve from his self-imposed exile in the desert. And Tony's not above bribery.
Rec Comment: This is probably one of my absolute favourite ults fic. A fantastic re-telling and fix-it of Steve’s self-exile. I love the characterisation.
~
Darling, let me touch you. by captainstars
Rating: Explicit
Universe: Ultimates
Warnings: Alpha/Beta/Omega Dynamics, Sexual Content
Summery: Steve is showering two heads away from the one Tony had occupied earlier. The water darkens his blond hair, cascading down his back in tempting rivulets that travel the dips of his muscles. His skin gleams under the water, slick and wet. And that is enough to stop Tony in his tracks, it is. But what really twists his tongue in his mouth, is the way Steve has his head thrown back, hands on his chest, firmly massaging his pecs.
Rec Comment: Fantastically hot fic!
~
The trick’s a treat. by captainstars
Rating: Explicit
Universe: Ultimates
Warnings: Sexual Content
Summery: Tony is very excited to show Steve his Halloween constume. Steve’s got a little surprise of his own planned.
Rec Comment: Steve definitely won Halloween. Wonderful story in which Steve and Tony wear super sexy costumes.
~
Heart’s desire. by captainstars
Rating: Explicit
Universe: Ultimates
Warnings: Alpha/Beta/Omega Dynamics, Sexual Content
Summery: Neither Steve nor Tony could have reacted in time to the purple blast that exploded out from the stone, bathing both of them in the warmth of its eerie light.
“You will realize it.” The man professed, his gaze startlingly clear for someone who had been rambling until then.
“You will realize your heart’s desire.”
OR
The fuck buddies + ABO AU.
Rec Comment: An absolutely fascinating A/B/O story. I love the idea and everything else really about this story.
~
Got My Both Eyes Out (For Mr. Right) by Electra_XT
Rating: Teens and Up
Universe: Ultimates
Warnings: None
Summery: “Oh, good, you’re here,” Tony said. “I was waiting for you. I have dinner.”
“Tony?” Steve said. “You have ten seconds to tell me why you broke into my home.”
Rec Comment: Wonderful angst and hurt/comfort. Poor boys are lonely and hurting.
~
Come On Mess Me Up by valdomarx
Rating: Explicit
Universe: Ultimates
Warnings: Sexual Content
Summery: Being president isn't easy, especially when you've got a civil war to deal with and your staff keeps sending you to PR events. Steve's had just about enough of the office, the deferential staffers, and the stuffy shirts that Carol makes him wear. What he really wants is for someone to come along and make a mess of him.
Rec Comment: A great story with president Steve. Tony works him over with his green suit goo. Super sexy.
~
Relax, Darling by valdomarx
Rating: Explicit
Universe: Ultimates
Warnings: Sexual Content
Summery: Steve is stressed and tense after a hard mission.
Luckily for him, Tony and his tongue are available to relax him in a variety of delightful ways.
Rec Comment: An absolute favourite of mine, I can’t count how many times I read it.

He Followed Me Home (Can I Keep Him?) by antigrav_vector
Rating: Explicit
Universe: Noir
Warnings: Sexual Content
Summery: Tony was hot on the trail of the Xi'an'du daggers with Pepper and Jarvis at his side, when another startling discovery left him feeling like he got slapped in the face with a fish.
Merfolk, it turned out, weren't as mythical as he'd always thought.
Really, in retrospect, he probably should have known better than to think that, after all his experiences with magical creatures and artifacts, but, well, he's not perfect.
Rec Comment: MERMAID STEVE!!!!! A great story, super fun read.

Summery: There is an intruder in Avengers Tower and Tony Stark is determined to find out who brought him in, but the identity of the culprit might surprise him.
Rec Comment: A wonderfully adorable story involving a pouting Steve.

Worthy to be Smooched by Neverever
Rating: Teens and Up
Universe: Avengers Assemble
Warnings: None
Summery: Steve finally finally has landed the date of a lifetime with Tony. Except he knows he's going to blow it big time. And what's worse, no one seems to care that Steve is different from Captain America.
Rec Comment: Super sweet story. I love stories that deal with Steve’s issues with being Captain America.

Velvet Worm Care
Helllo friends! A anon requested a Velvet worm care sheet, and I have researched! SO NOW IT’S TIME.
(source)
First off, what are velvet worms? They are from the order Euonychophora with two family groups. Peripatidae, which live in tropical regions around and above the equator, and Peripatopsidae live south of the Equator. Their true eyes are little teeny dots, and they rely on those front legs to touch things so they can get around and find prey! The ‘velvet’ appearance is a special water proof skin! They are one of the few invertebrates that give birth to live young, and can live around 5 to 7 years if cared for right. Some species, like Euperipatoides, live in a societal structure like a wolf pack, where close family hunt and live together. There can be as much as 15 individuals in a ‘pack’ They are a very old species, and have been around for 500 million years!!!
Velvet worms are adorable, but they are also quite vicious hunters! At night, they emerge and feel around for prey, which are other insects and invertebrates. Once they find suitable prey, they spray them with a sticky glue that prevents the prey from escaping. Once subdued, the velvet worm makes a small slice somewhere on the prey, and pump them full of digestive venom and then slurp up the liquefied insides. NO WORRIES, they can’t hurt humans. They don’t like to waste precious calories and energy going after something that isn’t prey.
Now then! What do they need for proper care?
Humidity and Heat
Velvet worms prefer cooler temperatures around the 60-75°F / 15-23 °C. A basement would be an example of a perfect place to keep these guys. Some owners even keep them in a fridge! They need an extremely high humidity, because unlike other invertebrates, they cannot close their breathing holes, so they dry out super fast. I would say at LEAST 80% humidity at all times. DO NOT USE TAP WATER. Most people use pure rainwater to mist the tank, you could also use river water or spring water. Be careful about spring water, because some of it is just bottled tap water. These are a sensitive species and can die if exposed to chemicals and heavy metals.
Substrate
Velvet worms enjoy mosses, because they retain moisture. So some cocoa fiber/dirt mix with some sphagnum moss covering the dirt should do the trick. They hide during the day, so provide them hiding places, like a little cave or a hollow log to hide in. They may even make their own hiding place in the dirt. The more damp and dark hiding places, the better. The substrate should be moist, but it doesn’t need to be sopping wet. Even though Velvet worms are waterproof, they don’t enjoy sitting around in standing water.
Activity
Velvet worms are nocturnal, so don’t expect to see them out during the day time. They can be seen at night, looking for food. I recommend a red light-bulb so you can watch them without bothering them too much. They mostly just chug along and are an easy going species. They can be handled, but make sure you wash your hands and remove any trace of lotions or toxins. They don’t bite people and think of us as really, really weird branches, so there is nothing to fear from them. For the most part, it’s best to let them be unless you are feeding them or checking up on them. Too much stress is never good for any animal, and constantly disturbing their rest during the day could lead to illness and death. Put your tank in a dark and less trafficked part of your house so they can rest well.
Food
Velvet worms are incredible voracious predators! They will eat just about any kind of invertebrate, so it doesn’t matter too much what you give them. Just make sure they are small enough that the velvet worm doesn’t get injured trying to subdue their prey. Crickets and grubs/worms are an excellent choice, but they will also dine on roaches and locusts. Velvet worms are careful about going after prey, because it takes a lot of energy and calories to produce the glue they use for hunting. To help them out, you could probably gut load your prey items before offering them to your worm. Most invertebrate prey items have less nutritional value compared to wild prey, so gut loading will help them out and give them a little extra nutrients.
So that’s what I have found out about caring for Velvet worms! Remember, there are several different species of velvet worm, so feel free to check them all out! Some come in rather beautiful colors and can be a really cool pet to care for. For example, look how stoked Coyote Peterson was when his camera crew found a red velvet worm. These animals deserve to be admired for their otherworldly beauty and uniqueness.
