Some 20 hammerhead flatworms have been spotted in Westmount. The invasive species from Asia secretes a dangerous paralyzing toxin and is increasingly present in North America.
Lisa Osterland, a retired teacher, discovered about 20 hammerhead flatworms (bipalium) in her garden in Westmount, a municipality on the Island of Montreal.
Earlier this week, while removing slugs that were eating the flowers in her garden, she noticed a type of invertebrate she had never seen before.
[...]
Their proliferation is a cause for concern, not least because this worm secretes a paralyzing toxin, tetrodotoxin.
"It's one of the most powerful molecules in the biological world, the same molecule that is produced by puffer-fish," Normandin said.
"If a young child puts soil in his mouth and ingests a flatworm or two or more, there's a real risk of damage. If ingested, it's a toxin that will first attack the perioral region — the face, the tongue and everything in the esophagus," and "in such a case, the child needs to be hospitalized very quickly," the expert added.
Here's a land planarian! Land planarians are commonly known as hammerhead worms despite not being annelids (segmented worms). While some species are invasive, they're a fascinating family of creatures that come in a stunning variety of colors/ patterns!
Please keep any comments about killing land planarians to yourself. Invasive species aren't invasive everywhere and can be appreciated and valued in their native range.
I love to generate heinous writhing vermin — @crevicedwelling (original post here)
[image ID] a portrait of a family of flatworms consisting of two adults with light brown bodies and dark brown stripes and characteristic shovel shaped heads, with a pile of shiny red eggs between them. above is a quote from Tumblr user crevicedwelling that reads "I love to generate heinous writhing vermin."

oh youre a lesbian? so are you the one who grabs the neurotoxic worm or the one who informs the one who grabbed the neurotoxic worm that it was a neurotoxic worm
You know that thing Wikipedia does where it goes deep into the detailed scientific authorial voice and doesn't clarify something you consider pretty fuckin key that shows up in the first sentence?
So I searched for hammerhead worms. First sentence: "Bipalium is a genus of large predatory land planarians."
Okay. I don't know what the heck a planarian is. (A flatworm, apparently.) I'm getting that it lives on the ground and not in water. I definitely understand the words "large predatory".
i do know that worms make up an astonishing number of the phyla of animals that exist, and some bristle worms can get up to 10 feet long. I know the longest tapeworm ever removed from a human was 82 feet long. I know I don't know anything about the sheer variety of worms on the planet.
At no point in this article do they define "large". Including the lengthy "description" section. What... what is large, for a predatory animal - oh, it's invasive too, that's lovely, and one produces a powerful neurotoxin, how charming - with whom I might share an environment? Large like a giant hummingbird (still little, but larger than all the other hummingbirds)? Large like a reticulated python (too big for one person to safely handle)?
(Three articles later, apparently one "very long" species makes it up to 20cm. Okay. So on the hummingbird end.)
hammerhead flatworms (Bipaliinae) are in my estimation among the most beautiful terrestrial animals, often sporting bright colors and striking patterns that advertise their toxicity.
bipaliines feed on either worms or land gastropods, tracking the slime trails of prey with their highly sensitive spade- or crescent-shaped head plate.
Southeast Asia is a hotspot for bipaliine diversity, and at least six species can be found in Singapore, all of which I managed to encounter this summer!
Making an enamel pin of Bipalium, preorder options include one with a discounted second pin from any pins I have available (or a second flatworm) and an option to add some random rubber bugs!
My Di Roy theory is that he's neither a hammerhead shark, nor an eel, nor a leech, nor all those takes I've seen floating around. He's a Bipalium, aka hammerhead worm. Poisonous, predatorial, cannibalistic flatworms. They also have a ventral foot just like his second head/mask in his Adjuchas form.
Ooooooh, I like this idea. 👀 I've pondered over Di-Roy's potential species inspiration for a veeeery long while now, and yep, the commonly seen interpretations never felt quite right to me either. Theory accepted!!! Thank you, anon!
[ID: Artwork featuring 17 different forms of a bipedal oc. Each form uses the same base, posing simply on a plain or patterned background and facing to the left - each variation has some kind of invertebrate replacing the limbs, and a corresponding color/hairstyle change. The first /default form has giant American Millipedes replacing their legs, with fluffy, striped hair covering their top face, a curly tail, and antennae matching the ones on their limbs, almost resembling a dog / bear. Other forms, from left to right, include a Giraffe Weevil, Mint-Legged Centipede, Stick Bug, Rhino Beetle, Fly, Ladybug, Common Blue Damselfly, Medicinal Leech, Shrimp, Garden Snail, Leopard Slug, Hermit Crab, Hammerhead Flatworm, Velvet Worm, Earth Worm, and Bald-Faced Hornet.

Swirlipede!
A weird little shapeshifter with the tendency to poke their nose in everyone's business. Dedicated question-asker and party-crasher, fe acts out their many personas via various forms to address situations in fun and dramatic ways. On a journey to discover themself and try out almost every role he can stick himself into.
As Swirli's introduced to more invertebrates to take inspiration from, more forms are bound to develop, so the list remains ever-shifting.
Also known as "Hancock's Flatworm," it has a distinct black coloring and is part of a genus known for engaging in "penis fencing" for reproduction, which I like to imagine is something Izzy does too. Obviously I would still love him; I don't think there's anything that could make me stop loving him.
Stede: Sabellastarte spectabilis
Also known as the "feather duster worm." It's popular in squariums because of its flamboyant plume of tentacles, which are almost as ridiculous as Stede's hair. If anything I think I'd love him more as a worm.
Ed: Eunice aphroditois
Also known as the "sand striker" or "bobbit worm." This thing is a horrifying monster that feeds on fish unfortunate enough to come near it with its sharp mandibles. The rainbow iridescence is pretty though. Sorry Ed but I've read too many horror stories about these; I would not love you if you were a worm.
Calico Jack: Trichuris trichiura
Also known as the "whipworm," which is the only reason I chose it. Unlike Calico Jack, I wouldn't want one of these in my large intestine because they're the cause of trichuriasis, a parasitic infection. I'm not that into parasites so I'm unfortunately going to have to pass on loving Jack as a worm.
Roach: Hirudo medicinalis
One of a few species of "medicinal leeches." Leeches are still used for medical purposes to this day because of the beneficial secretions in their saliva, and they're also cool as fuck. They're like vampires except they're worms, so obviously I'd still love Roach as a worm.
Frenchie: Lagis koreni
Frenchie is a "trumpet worm" because that was the only worm I could find with a name related to music. Also the tubes they build for themselves to live in are super cool and I wanted to include them somewhere. I would for sure love him if we was a worm.
Wee John: Megascolides australis
Also known as the "giant Gippsland earthworm." Because he's big, get it? 10/10, would still love him as a worm.
Lucius: Spirobranchus giganteus
Commonly known as the "christmas tree worm." The two spiral things on either side of its body function both as gills and to capture food, and they're also gay as fuck. Love that for him, and I'd absolutely love him as a worm.
Jim: Bipalium kewense
Jim is a "hammerhead flatworm," mostly because it kind of looks like it's wearing a hat but also because it produces a deadly paralyzing neurotoxin. Obviously I love that, and I'd love them if they were a worm.
Oluwande: Maritigrella crozierae
Commonly known as the "tiger flatworm." I chose this for Oluwande because they apparently often live together in pairs and Jim/Oluwande is the best couple in the show. You already know I'd still love him if he was a worm.
Buttons: Plagiostomum vittatum
Not much is known about this mysterious species of marine flatworm aside from the fact that it's native to the Atlantic ocean (by which I mean there isn't a Wikipedia article for it and I can't be bothered to do more research). I do like a mystery so yeah, I'd love him if he were a worm.
Fang: Hermodice carunculata
The "bearded fireworm," like Fang, looks soft but is also deadly. It's namesake white bristles are capable of penetrating skin and injecting a powerful neurotoxin. I would love him if he was a worm but I'd keep my distance.
Ivan: Arthurdendyus triangulatus
Known as the "New Zealand flatworm," it fades into the background a bit but it's still cool. Apparently they roll up when they rest which would be really cool if I could find a picture of it. Anyways yeah I'd love him as a worm.
The Swede: Caenorhabditis elegans
C. elegans is a species of nematode notable for being the first multicellular organism to have its entire genome sequenced, because it's so simple. I'd definitely love him as a worm.
Black Pete: Lumbricus terrestris
The common earthworm. It's a bit plain, but it plays a vitally important role in its ecosystem. Of course I'd love him as a worm.
Mary: Riftia pachyptila
Also known as the "giant tubeworm," it's capable of surviving in the extremely hot, toxic environments of deep-sea vents, which is almost as impressive as Mary being able to survive living in a house with Stede. Obviously I'd still love her as a worm, she's an icon.
