Grandpa Squarepants is a synthetic kitchen sponge. 

Grandma Squarepants is an aplysina fistularis - the yellow tube sponge.

Harry Squarepants, as a result, is a hybrid sponge - but legally considered just an aplysina fistularis.

Margaret Squarepants is a hippospongia communis - the honeycomb bath sponge.

Spongebob, therefore, is mixed aplysina fistularis and hippospongia communis and part synthetic kitchen sponge. Resembles his grandfather most appearance-wise, but with a texture more like Margaret’s.

Spongepink (the bootleg spongebob schoolgirl) is an aplysina archeri - the stovepipe sponge.

(Lovelypants, if you want to see him as separate from Squarepants, could be seen as an aplysina archeri too)

Dylan (the boy spongebob fan power from super brawl 3) would be an aplysina cavernicola 

Bobbi (the girl spongebob fan power from super brawl 3) would be an aplysina aerophoba

Spike & Thistle (the abrasive side fan powers from super brawl 3) would be two aplysina insularis - yellow-green candle sponges

Rachel (from the spongebob beyond fan yt series) is an aphrocallistes vastus - the glass sponge.

👻 for benny? (If u don’t mind that is)

Of course!

👻 for a fear headcanon

Benjaminson is... Both very hard and easy to scare, it's complicated, if he's in a good mood a paper ghost could easily scare him but if he's bored not even the scariest person in NRC can't impress him

If we're talking about serious fears, he absolutely fears failure

oh yeah! started working on my own take on nicktoons unite gang 'glow ups' sea sponges don't change much but i can't leave the guy out so heres this >:D

artist ramble under the cut

-shout out to my lettering work it looks nice >:D

-i asked myself 'what items would spongebob carry on him at all times' and preceded to project 'items i would carry on me at all times if i could'

-decided to go with a pie-cut instead of pupil for the eyes because i'm hoping it'll make him look extra cartoony next to the rest of nicktoons unite gang

-almost gave him gary slippers instead but than i remembered sea bunnies and that idea won

-almost gave him the non binary flag or just the asexual flag for that one tie but the aroace flag reminds me of a beach so it was the winner for that

-i forgor to color the lines in the sleeves on the far left :(

-btw the spongebob wiki has a page for spatulas that legit is just

-there is actually like consistent hole count and placement for spongebob but i decided to ignore that sense 1. I am drawing this as one guy and not for an animation team. 2. because it's not like, significant, idk the word for this but essentially the concept that accuracy doesn't matter as much as believability and clarity, for example, when someone animates an instrument they likely won't have it be animated 'correctly' because it doesn't need to be in order to give the illusion that the instrument is being played. except in this case it's that the exact placement and number of sponge bobs holes isn't significant to the recognizability of the character and the iconography is kept at long as they're present. the same concept is actually also present in the drawing of that silly straw! the actual direction of it doesn't make sense but that doesn't matter because it's identifiable. and lastly 3. because the holes are like placed to fit around his face and I exaggerated the proportions differently and thus they're fitted around differently

-for the outfits i wanted to keep in mind the 'nerdy' aesthetic, and than just saturate the hell out of the colors. that grey is actually purple

-the way i can spell aplysina fistularis but had to fucking triple check how neutron is spelled

Sea sponges launch slow-motion snot rockets to clean their pores

Time-lapse video reveals the surprising way debris-filled mucus moves out of a sponge’s body

The next time you spot a sea sponge, say “gesundheit!” Some sponges regularly “sneeze” to clear debris from their porous bodies.

As filter feeders, sponges draw in water through inlet pores — called ostia — and strain it through an internal canal system for nutrients. But there are also inedible bits in the water, like sediment. 

To prevent the undesirable junk from clogging up their outer pores, a Caribbean tube sponge (Aplysina archeri) uses mucus to trap and sneeze out unwanted particles, Niklas Kornder, a marine biologist at the University of Amsterdam, and colleagues report online August 10 in Current Biology. To the team’s surprise, it found that the sponge expels its snot from the same pores through which it absorbs water...

Sneeze by Sneeze, Sponges Fill the Seas With Their Mucus

Sneeze by Sneeze, Sponges Fill the Seas With Their Mucus

You might be tempted to say “gesundheit,” but the sea creature’s snot helps feed other marine organisms.

Sneezing is far from a uniquely human behavior. Maybe you’ve seen your dog or cat do it, or watched a YouTube video of a giraffe sneezing on an unsuspecting toddler at the zoo. In fact, sneezing doesn’t even require a nervous system, let alone a nose, and dates back to some of the first multicellular animals: sponges.

The sponge has been around for at least 600 million years. “It’s the most successful animal that I know of, because it’s so old, and it’s everywhere,” said Jasper de Goeij, a marine ecologist at the University of Amsterdam. As filter feeders, sponges play a crucial role in their aquatic ecosystems, drawing in water filled with varied organic matter, processing it and releasing it as waste on which organisms like snails, brittle stars and tube worms feed. “A sponge is basically an animal that has a lot of little mouths and one, or several, larger outflow openings,” said Dr. de Goeij. Those “little mouths” are called ostia, and the openings where water flows out are oscula.

For years, scientists have known that sponges can regulate their water flow with a many-minutes-long body contraction — i.e., a “sneeze” — but now, Dr. de Goeij and colleagues have found that sponges appear to sneeze as a form of self-cleaning, releasing waste particles in mucus through their ostia. The work was published in Current Biology on Wednesday.

The researchers came across sponges sneezing snot while working on a project investigating the role played by sponges in moving nutrients through a reef ecosystem. The work required Niklas Kornder, another marine ecologist at Amsterdam, to spend a lot of time with sponges. “I would spend entire days just looking at the surface of them; it was quite boring,” he recalled. (Mr. Kornder was scuba diving in the Caribbean at the time.)

All three of these marine sponge species are probably sneezing right now.Benjamin Müller

Fortunately, things got more interesting when he started seeing opaque stringy material coming from the sponges. “Then I’d come back to it later, and the stringy things would be gone,” he said.

To figure out what those “stringy things” could be, the researchers recorded time-lapse footage of sponges, specifically the Caribbean tube sponge Aplysina archeri. In the lab, they were able to identify the threads as streams of mucus carrying waste. They would come out of the sponge’s ostia, move across the organism’s surface and aggregate into clumps that could be released with a sneeze, and then quickly gobbled up by other ocean critters.

When first reviewing the time-lapse footage, Yuki Esser — a bioinformatics graduate student at Amsterdam at the time and a study co-author — was disappointed, thinking that the movement she was seeing (i.e., the sneeze) was just a camera focusing error. “I thought there must be a drop of water or something on the camera lens causing this,” she said. But she soon realized it wasn’t a mistake. And once Ms. Esser and her colleagues found they had captured nearly identical time-lapse video of A. archeri off the coast of Curaçao, recording footage “became kind of a sport,” she said. “Like, ‘Maybe we caught another sneeze on camera!’”

The researchers believe sneezing out waste-laden mucus is a widespread tactic among sponges all over the world. And the study stirs up more questions, said Sally Leys, an evolutionary biologist at the University of Alberta and a co-author of the study.

“The mucus,” she said. “Is it similar to other animals’ mucus? And what cells are making it?” She also wants to know what triggers the sneeze. “When our nose is dripping, we bring the Kleenex out,” she said. “But how does a sponge know that this is the moment to sneeze?”

Studying this mucus might improve scientists’ understanding of how microbes, and possibly disease, are transmitted in reef ecosystems, said Blake Ushijima, who studies corals at the University of North Carolina Wilmington and was not involved in the new research. He’s also struck by what this study could teach us about our own evolution.

“This could give us hints of how early life evolved from these squishy brainless things into these complex organisms building spaceships,” Dr. Ushijima said.

Happy 22nd anniversary to my favorite Aplysina Fistualis!

Can’t believe it's been so long since 4 year old me witnessed the beautiful and vibrant world of Bikini Bottom for the first time, and never stopped loving it.

Thank you so very much for all the wonderful memories and many laughs. Thank you for getting me through the toughest of times and for my love of marine life and animation.

You are and forever will be so missed, Stephen Hillenburg.

I FINALLY MADE SOMETHING ON TIME FOR MERMAY! I’ve been super into actual irl sea sponges lately so I thought hey wouldn’t it be cool to like, take a bunch of characteristics from different sponge species and mash them together into a mer-sponge??? So thats what I did! Plus a little half-snail half-cat Gary :3

(some sketches and sponge references i used under the cut! and don’t forget to check out my ko-fi!)

the common antler sponge was the first one to give me the idea of the like, antlers (pictured below)

then ofc aplysina fistularis, the yellow tube sponge (and according to the musical, the exact species spongebob himself is!)

aaand finally i mixed a bunch of other species of glass sponges for little details here and there, but mostly the venus flower basket sponge, which was so pretty i had to
