Siphonophores are these delightful critters that live beneath the sea.
What's so special about them, you ask? What's special is that a single Siphonophore body is actually made up of a bunch of tiny organisms called
These
They are also generally bioluminescent. They are
2 out of 3 siphonophore types use
Nectophores are zooids which are basically tiny rockets which use jet propulsion to push the siphonophore in the water. How cool is that!
Nectophores are arranged at the "head" of the siphonophore, called the
Let these fine fellows demonstrate
Truly beautiful.
The siphonophores which don't have nectophores have a floatation device called
Siphonophores, or order Siphonophorae, are members of Phylum Cnidaria (the stingy sea creatures like jellyfish).
As I've alluded to above, Siphonophorae is divided into 3 suborders based on the presence of
These have a bunch of nectophores on their nectosome. The fine fellows you saw swimming above? Those were all Physonects!
They are very mobile and usually swim in the open ocean
These have very few nectophores, usually only two, which make them look like rocket jets. They can suck up their
Some of them have an
They don't have swimming bells so they usually float along the surface, drifting along with the wind or the currents.
Arguably the most famous siphonophore, the
Siphonophores are so biologically interesting, both as Cnidarians and as colonial organisms. There is so much to learn about them and we haven't even scratched the surface yet. Siphonophores are very delicate so it's hard to study them so very little information exists on the more niche species.
Thus siphonophores remain a tantalizing look into a lifeform so alien to us, yet they are beautiful critters. You can spend hours being mesmerized by the video of siphonophores swimming (or atleast I have).
This is one of my most favorite videos to look at from time to time:
This is likely the best place to mention that I'm not a marine biologist, or any kind of biologist. I only have a passing interest in biology, but researching about these fascinating creatures have made me learn a lot more about ocean life. Atleast I can throw around big words like
This is the video that first got me into Siphonophores:
Go check it out! It's a far more comprehensive look into Siphonophore biology than I've had the wit to elucidate here.
Also, yes. Siphonophores are the namesake of my website.
Dishonorable mention: Portuguese man o' war. Overrated. Boo. (don't tell her I said this)
I realized I had no Calycophorae on the list. I am currently
But they do genuinely look cool though. Tent lookin' ass.

I mean look at them! They look ethereal, almost angelic. They look like if the Light Dragon from Zelda was a tad more eldritch.
They look so fluffy but those are just their stingers. Don't try to cuddle one(?), please.

They're a cystonect but they don't idly float on the surface. Instead they contract and relaxe their siphosome for movement which is really neat!
Image from the Serpent Project Media ArchiveIn 2020, an individual of genus Apolemia was found, in a spiral position, off the shore of Western Australia (pictured here). Its full body is purportedly
To put that into perspective, that is just a little over 85 metres longer than the longest blue whale ever recorded.
It is commonly known fact that siphonophores are one of the longest creatures alive right now, with the
Also Apolemia uvaria was nicknamed by New Zealand folk as the
My beloved, the closest thing the sea floor has to a pinata. They look so cute what with the bunch of cute little nectophores and tentilla and I just wanna give them a big hug even if they burrow into my skin and kill me badly.
They belong to the Rhodaliidae family, a kind of Physonect siphonophore that are benthic in nature, i.e. they attach themself to the sea floor by the tentilla instead of roaming the open ocean.
I have so much love for this silly goober. Content in its own patch of the sea floor. Moisturized. Unbothered.
Image by MBARIYep. This was inevitable. Here it is:
Of course, it's based on Rhodaliidae, and it's benthic.
I'd love to become a siphonophore. It wouldn't even be me anymore. The egotistical conception of a self would be lost in the sublime collective abstraction.
I would eat fish and bob around nonchalantly.
Jon is a stereotypical Physonect. Martin is a Woolly siphonophore. Can I make it more obvious?
The entire playlist is a delight but the "hunting with tentilla" video is a particularly enlightening on how siphonophore nematocysts are very peculiar even among cnidarians.
