Salps are gelatinous animals that live in the open ocean, but are closely related to the "sea squirts" (tunicates) seen in tidepools. Colonial salps often form long chains, with new animals budding off from others in the chain. They can reach up to 15m long and are one of the fastest-growing animals on the planet. Salps rhythmically contract their bodies to propel themselves through the ocean and pump water through their guts, filtering out microscopic algae and other tiny organisms for food. They play an essential role in mitigating climate change as their fecal pellets are full of carbon and sink rapidly to the sea floor, sequestering that carbon for decades or even centuries to come.
The salp chain you see here is the rarely observed, Helicosalpa virgula. It was captured on camera by our remotely operated vehicle (ROV) Doc Ricketts 282 meters (925 feet) deep.
Look at these guys!! And I thought that the Longnose Lancetfish looked like something out of Subnautica…
They’re little jelly dudes, no bones. Technically they fall more under squishy or gelatinous than they do ‘chunky’, but not having bones gives them a lot of points (Plus I very much want to hold one in my hand). High chunk. Looking at these guys, they’re so very unique and their behavioral patterns are really interesting! High funk. Finally, they are little jelly dudes, of course they have gunk! In addition to that, they also secrete nets made of mucous in order to eat, so they most certainly are gunky. To be honest, I can’t figure out if they’re gunky enough for a maximum gunk rating. They’re definitely slimy and they definitely MAKE mucous, but I feel like a creature should secrete SLIME in order to get a full 10/10 gunk. Then again, I’m just not sure! What do you guys think?
Overall: 10/10
I want to hold one. I think they would feel like peeled grapes.
Oh! Fun fact from my research: these guys are NOT related to jellyfish! They’re actually closely related to people, since they’re in the family of “animals with backbones”.
(I mean, they don’t really HAVE backbones anymore, but nobody’s perfect.)
Oh! Btw! More photos!
vv I made this :) vv
⚠️ Below this are images of salps being held out of water ⚠️
These jelly creatures are actually some of the closest relatives of vertebrates! Descended from sea squirts that became free-swimming again, all of the world's oceans have been invaded by these alien-looking organisms!
They have mastered their cloning ability to an incredible extent, with a single salp being able to reproduce and form chains of hundreds of individuals, floating in the middle of the ocean! Their life cycle is actually pretty unique, alternating solitary, sexually reproducting individuals with giant clone chains!
Phylum Chordata (aka the phylum with VERTEBRATES... disgusting), class Thaliacea, Order Salpida
They can come in a few shapes and sizes but these are colonial creatures (similar to Siphonophores like the Man whore but each individual is actually an individual, not a poorly defined organ/organism zooid)
They filter feed and are very silly. Chains can be longer than a blue whale because of course they are.
Anyways my hatred for them is mostly silly and mean spirited but if I'm going to be known for anything in the jelly community or jellyfish fandom, it's going to be my comical hatred of salps. And maybe comb jellyfish (beroe comb jellies scare me haha)
Btw, these are Pyrosomes (also known as fire bodies):
Same class, just in Order Pyrosomatida
They have a lovely bluish-green light display very characteristic of bioluminescent organisms and are very bright (just like the Periphylla jellyfish!)
Here's the image shown in Lisa Ann Gershwin's book! It's very pretty
When the photographer isn't making an effort to make them look pretty, I think they actually look kind of stupid, haha. But isn't that the appeal of jellyfish? To look stupid?
Salpingectomy is great but I see the word and I can think of is a procedure to keep you from turning into a salp
I don't think a salpingectomy would help a salp, though. It's during their asexual reproductive stage that they produce a whole chain of babies attached to them (the babies then going on to sexually reproduce and get pregnant with their own babies, still attached to the asexual grandparent). Photo of the baby chain with a diver for scale:
Incidentally, they're more closely related to us vertebrates (animals with bones) than any other animal--we're both chordates!
While closed circuits are loops and open circuits are more like unconnected paths, the way components are arranged can change the calculations behind the effectiveness of those components. In series, the components are linked to each other end-to-end with resistance and inductance calculable with simple addition while capacitance requires the sum of reciprocals to find the total’s reciprocal. In parallel, the path is split into different lines to reach different components. Between components of different paths, resistance and inductance must now be summed by their reciprocals to find the total’s reciprocal while capacitance can just be added to find the total.
Bulps [Series Form] (Electric/Fairy): The head Bulp is actually an adult of the species as younger Bulps come to attach themselves to feed off of the adult. Bulps in this form are flexible, but this makes them take longer to coordinate and move together.
Bulps [Parallel Form] (Electric/Fairy): Bulps in this form have to share a split flow of energy from the head Bulp, so each Bulp is a little weaker. While Bulps may be weak on land, they can dominate their natural habitat by utilizing their electrical skills.
Would you guess that these jelly-like organisms are more closely related to humans than they are to jellyfish? Sea salps are tunicates and members of the phylum Chordata, which also encompasses vertebrates and cephalochordates. Jellyfish, on the other hand, are a part of the phylum Cnidaria, which includes the likes of corals and sea anemones. There are more than 45 species of salps that inhabit much of the world’s oceans. As filter feeders, they mainly consume phytoplankton but will also snack on other tiny particles that might float their way. Salps eat by pumping water into their mouths and out of their atrial openings, propelling themselves as they feed.

This little shrimp just hijacked a salp as its personal housing! Jumping inside salps or jellyfish for protection, hyperiid amphipods use their legs to propel the barrel-shaped jelly, becoming the propeller in this unique symbiotic sea vehicle! These interesting creatures even inspired the xenomorph queen in the movie Alien!
