Have you ever wondered what planaria look like?

Planaria are a common freshwater aquarium pest and mine came into my tank hiding in some plants from a new LFS. They don’t pose much of a risk to fish but they will eat shrimp, fish eggs, and—surprisingly— snail eggs. They’ve been keeping my red ramshorn snail population under control, but they’re also taking their toll on my zebra shrimp.

Luckily, they’re pretty easy to get rid of. Believe it or not, I used a dog dewormer called Panacur to treat my tank. Panacur contains fenbendazole, which is fish and shrimp-safe but will kill these guys! My Indian zebra shrimp population has already doubled since treating the tank about 3 weeks ago.

planaria i just caught! honestly i think they're cool, if they weren't harmful to livestock (they're a predatory leech that goes after baby snails, vulnerable shrimp, and fish larvae) I'd just let them vibe.

#a lot of treatments are harmful to other invertebrates so i wanna be careful #first thing I'm doing is evacuating the breeder box of baby mysteries #idk if the planaria could even get in there but just in case #m2a #fish tag #fishblr #planaria #leech #bug #worm #including those tags for cws

I'm gonna post Eclair again

Just easing back into posting character stuff a little bit.

Another introduction:

Eclair's a planarian "vampire" of sorts, guards a hidden library filled with information they cannot read.

Eclair has extremely foggy memory, often misplaces things, and is quite enamored with wearing gaudy patterns. Rather passive and uncaring.

Can split into two, and then four, small versions of themself at will. The more they split, the less scatterbrained they are. Can also just be a big planarian.

If cut physically, the offshoot is a zombie-like planarian that can be manipulated to Eclair's will, often for weapons or surveillance.

for that ask game: your opinion on worms? any kind is fine

OH MAN. worms are one of my special interests (hence the worm themed usernames on my blogs lol) and i have A Lot to say. worm rambling below the cut. ive included some images, so if anyone here is grossed out by worms i would recommend not clicking the keep reading button

OK SO. i love all worms but my specific interest is in flatworms (platyhelminthes) so im going to talk abt them here! im especially into terrestrial flatworms (geoplanidae) but marine flatworms and smaller planarians are also very cool!

one of my favourite things abt flatworms is the variation among them. obv there's a lot of difference at higher taxonomic levels, for example you get

polycladida, the numerous and varied marine flatworms that are free swimming and often have two short tentacles on their heads, and many small ocelli! they are quite large compared to other flatworms in general too!

freshwater triclads, which are small and brown and live in freshwater, and usually (although not always) have two eyes!

and geoplanidae, the terrestrial flatworms, who inhabit gardens everywhere and usually (although, once again, not always) have many small ocelli!

there are more taxonomic classifications, and this isn't rlly a particularly scientific or accurate way to define them, but it's how i tend to split them up in my head lol.

geoplanidae are my favourites bc they're very easy to find where i live, and they're very beautiful and there's so much variation within the family. all of them are carnivorous, and although they will scavenge, they're often active predators and hunt other worms and also gastropods. their many ocelli (eyes) are usually pretty small and they can't see much at all, with the exception of species like the new guinea flatworm (platydemus manokwari), which is invasive in the US and has two large-ish prominent eyes on either side of its snout, and has better visual acuity than most flatworms iirc.

(see its beady wee eyes!!)

the majority of geoplanidae use chemical senses to track down their prey! because snails/slugs and other worms leave trails of slime, which are often imbued with pheromones to attract mates etc, predatory flatworms can track down their prey by following the chemicals in these trails.

once they've found their prey, they will wrap themselves around it and excrete a mucus which they use to slow down their prey. they're very strong as well so will often overpower prey using physical force! after this, they use their eversible pharynx (a kind of muscular tube) to penetrate or grasp their prey. the pharynx produces digestive chemicals through special glands. the prey is effectively digested externally, after which the flatworm will eat it.

it's a little bit horrific, but also very cool imo. flatworms can have mixed impacts on their environments, in native areas they can help control pests and keep the soil healthy, but if they become invasive they can decimate native worms and snails/slugs, which can decrease soil health. it really depends on if they're native or not.

terrestrial flatworms come in a wide variety of shapes and sizes! many of them are pretty small and long with some kind of a stripe going down the middle, as you can see in this personal photo of mine of a newzealandia graffi flatworm:

although there are many brownish flatworms, there are many others that come in lots of different colours, like this creamy-orangey one in another photo of mine (australoplana sp.):

or the blue garden flatworm (not my photo, caenoplana coerulea):

or even beautifully patterned ones like this unidentified flatworm!

within geoplanidae, there are also hammerhead flatworms (subfamily bipaliinae), named so because of their hammer-shaped head, usually lined with ocelli around the edges:

this species is bipalium choristosperma, and is native to borneo iirc! some other species of hammerhead flatworm, i.e. the brownish bipalium kewense (im running out of pics for this post rip so no image for this one but you can google it if you're curious!) are invasive in certain areas of the united states.

other geoplanarians are invasive in some areas, like the aforementioned platydemus manokwari which is also invasive in the US, or the new zealand flatworm (arthurdendyus triangulatus), which is invasive in the UK (despite it being called the new zealand flatworm, i have yet to actually see one irl and i live in its native, non-invasive range lmao 🤷‍♂️). like many other invasive animals, they're very good at getting into places undetected (esp plants/soil being transported, which is how they usually make it into new countries), and are just very efficient little predators. which is unfortunately bad news for gastropods and other worms lol

geoplanarians can also get quite large! check out this Obama eudoximariae specimen (not named after the president lol)

however most are usually a lot smaller than this. the flatworms where i live are usually no longer or wider than my pinky finger.

another cool fact abt flatworms is that many species can survive being cut in half, in fact each half will go on to form a new flatworm! some species will intentionally split themselves in half, or reproduce through "budding" where another flatworm just starts growing on them and eventually splits off. this is all asexual reproduction, but as well as asexual reproduction many species also reproduce sexually and lay eggs. they're such cool little beasts and have so many tricks up their nonexistent sleeves!

many species also glow in the dark under uv light. ive run out of images to add but it's cool as hell, my profile pic on my creature side blog is a photo i took of one of a newzealandia graffi worm glowing under uv light/blacklight. very cool of them to do that

ANYWAYS this post is getting long as hell and i have other stuff to do today so im gonna cut it short here. i hope you enjoyed my worm ramble :-) for anyone who is curious, i post more abt flatworms and other animals i like on my side blog @geoplanidae :-) <3 🪱
