Will always take the chance to post about penis fencing
![• Turbellaria (free living flatworms) -
Hermaphroditic flatworms reproduce by "penis fencing". Individuals "fence" with penises, attempting to use their penis to pierce the skin of the other and inject sperm. The 'loser' is the flatworm which is inseminated and must bear
the energy costs of reproduction. One study of Pseudoceros bifurcus found "Most inseminations were unilateral. Even when reciprocal penis insertion could be achieved by the second partner, the first to inseminate obtained a longer injection time than the second."[24][25] In another species,
Macrostomum hystrix, the worm may also inject its sperm into its own head if other mates are not available. 26]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:b4z65u3xeqgvghmg4koidrqf/bafkreieigdrk5x4wt6pn6uv5kfgphn7mknnjexendcsjewds43xeomhsim)

it is sooooo yaoiful that some flatworms have mating rituals where they both try to stab each other with their penises and the loser has to become the mommy

This is Linda the Linda's flatworm, a very pretty species that let me try out using pony beads for coloured spots. Her spots glow in the dark, too!

Which animals can regrow lost body parts?
The short answer: many animals can regrow lost body parts, but the ability varies dramatically across species. The champions of regeneration include planarian flatworms, which can rebuild an entire body from a small fragment, and axolotls, which regrow…

Which animals can regrow lost body parts?
The short answer: many animals can regrow lost body parts, but the ability varies dramatically across species. The champions of regeneration include planarian flatworms, which can rebuild an entire body from a small fragment, and axolotls, which regrow complete limbs including bones, muscles, nerves, and skin. Starfish regrow arms, zebrafish regrow heart tissue and fins, and newts can even regenerate their lenses and retinas. The mechanisms behind these abilities are conserved across species, and scientists study them with the hope of one day applying the lessons to human medicine. Regeneration is not a single ability.

“freshwater planarian flatworms bodies are packed with adult pluripotent stem cells called neoblasts. If you cut a planarian into pieces, each piece can regenerate a complete, fully functional organism—including a new brain, eyes, and digestive tract, in about 1 to 2 weeks” 🔪🪱🗡️🪱🪱🪱🤯

There's this philosophical choice I'm making inspired by the genetics of flatworms, of all things. They're committed to an environment where everything is chaos garbage, and have a huge genome mostly committed to error correction. That resilience is the subject of intense research. I relate to that.

There was an episode of the newer age Outer Limits about an experiment to grow hair. It worked wonders for the dude, until he went to cut it. It shrieked at him. The "hair" was a black alien flatworms, and the ends opened upto a mouth with little sharp teeth.

I don't get it. It's everything. That's already a kings capture. Did we just give up on antitrust laws and fighting mass consolidation after the 90's? I was a kid then but I remember the government forcing the largest company in the world and its richest man to split like flatworms?

Bugs don't bother me one bit. Spiders far less than they used to. Other critters people tend to find "icky" don't even register but I cannot separate my disgust from my scientific curiosity when it comes to flatworms and nematodes. Cool find though.

It's the perfect comparison. There are four classes of flatworms, three of which are entirely or almost entirely parasitic:
Turbellaria (free-swimming predators)
Cestoda (tapeworms, no digestive system)
Monogenea (external parasites of fish)
Trematoda (flukes, this is the most apt comparison)

Okay so you know how flatworms and cnidarians have a single digestive orifice? Food goes in the hole, poo goes out the same hole.
Now what if you took two flatworms and glued their holes together. You'd just have an endless poo exchange. That's exactly what this is. Poo flowing back and forth.

I've been trying to figure out the name of these flatworms in my yard, which have a black body but a tan face. Today, I think I have finally found the answer: the species doesn't have a name yet. It's just called Genus Name sp. "red head", and one knows where they came from. Cool.

There are definitely cases of probably not-
- flatworms that swim until they sense darkness
- flies that fly because their feet are off the ground
but the cases of "probably" are a lot more than most people want to consider.
(OTOH animals eating other animals is pretty normal)

I’m curious about where the line is for having a right to exist. I assume it’s OK to kill bacteria, especially if they’re killing you. How about microorganisms? They’re animals. So are corals, flatworms, mollusks, bivalves. Are we still OK? How about worms, insects, sponges, starfish? What’s OK?

Flatworms: what do you mean if you cut it in half the front half grows a new tail and the back half grows a new front and now you have two worms???

Planarian flatworms regrow their brains. New research found genes that tell stem cells which dopamine neurons to make and where they belong.

When we think of worms, we imagine long, soft-bodied, legless animals. But which one exactly? The answer isn't simple: Earthworms and leeches (Annelida), Roundworms (Nematoda), Flatworms (Platyhelminthes), and parasitic worms and insect larvae, such as moth, beetle, fly.
