Lacrymaria: Vicious Long-Necked Predators

Or maybe Loch Ness is actually a VERY small lake? The Scots are prone to exaggeration, you know?

[@sinait8191]

Imagine if giraffes actually behaved like Lacrymaria. You're visiting the savanna, there are pieces of animal gore everywhere and suddenly a Giraffe whips it's neck between trees, bushes and rocks to eat a hippo or lion alive by swallowing it whole, it's neck stretching like a sock around the animal as it struggles to escape. I'd like to see Junji Ito make a story about that.

Lately, I've been contemplating the idea of a D&D campaign set underwater, with all amphibious player characters. Watching this video, it occurs to me that populating the oceans with giant bacteria - macro-micro-organisms, if you will - would be an interesting way to add variety to the campaign. As well as danger. A Lacrymaria the size of a horse would be a frightening thing to face. Its "neck" extending and coiling around corners up to 100 feet away. Probing coral reefs, sargassum clumps, or the halls of some sunken dungeon. Its attacking poisoning and grappling PCs, and trying to drag them back to be enveloped and digested.

[@Norwyn]

You could also think about shrinking the characters. An adventure in a drip of water with playable water bears and rotifers and "giant" plankton bosses would also be interesting. Or do both ^^

[@SauqinaR]

Omg. This is lit

[@dismae_]

I was having similar thoughts for an underdark encounter, or perhaps a swamp creature of some kind

[@cycoholic]

I seem to remember an old Dragon Magazine article that had stats for a few of the microscopic beauties in a larger form. Can't remember what issue though.

[@druid_zephyrus]

That is a genius idea! Mind if I modify it and borrow permanently?

[@MalcolmCooks]

imagine a macro-sized animal using lacrymaria's hunting method though a long tounge or tentacle that probes the forest floor looking for prey to ensare and drag back to the main nody of the aninal

[@netsch20]

I mean about as close as I can think is an anteater, and to a lesser extent chameleons. And in a way I guess you could say snakes? So I'd say if you take the long tongue hunting method of an anteater but made the tongue a 10 foot long snake that could eat it's prey whole, as lacrymaria and snakes can do, then you'd have it!

[@GLaDTheresCake]

@@netsch20 The first thing I thought about seeing the lacrymaria was a cone snail. They also use a tube shaped protrusion, and use it to inject venom from it after finding a target. Maybe not a vertebrate, but it's definitely a macro sized animal with a very similar method of predation (and defense).

[@ProjectDarkWolf]

I cannot imagine anything more terrifying than the concept at 4:37 - a predatory megafauna with no prey selection, no persistence but high efficiency; where no matter how quickly you move, how little noise you make, you stand just as much chance as any other living thing around you at any given moment of a gigantic neck whipping out from god knows where, taking a bite out of somewhere, anywhere, on your body, and then just leaving you, bleeding and helpless, for scavenger species to finish off. Absolute nightmare fuel. But, probably also driving a healthy ecosystem.

I was watching an amoeba eat a paramecium almost as large as itself in biology class in college when I noticed the paramecium developing cracks in its outer membrane. Shortly thereafter the amoeba stopped moving and began to rupture and release grainy fluids. When I was sure they were both dead I asked the instructor what was going on. He asked how long I'd been looking at the same slisde and I said ten or fifteen minutes. He said "When they do that, it means they're done." As in "The food is done." The slide got so hot under the lamp that it cooked them both.
