Those who've known me for a while know that I typically prefer remembering a jellyfish's scientific name over their common name, but why?
Well... it's mostly for simplicity's sake. Jellyfish have been around a lot longer than humans have, and as a result, many species have accumulated multiple confusing and misleading names.
It's just easier to know them by scientific name, which typically have more of the truth in mind.
Many more don't even have a common name... so it's also sort of a thing I do to keep things consistent.
Also, some scientific names are really cool. Like for this jellyfish:
Would you rather call it the "Black Sea Nettle" or the Chrysaora achlyos?
(I talk about the etymology here if you're interested in knowing the names of the Greek Deities that make up its name. It's very cool and would take way too long for me to explain on this post)
Look at the size of this black sea nettle (Chrysaora achlyos), diver for perspective A jellyfish that can reach lengths of nearly 20 feet (6 m) | source
Can you tell us anything about the Chrysaora achylos?
I'm obsessed with them and as someone living on the east coast, I have no hope of seeing them in person :( 👉👈.
Of course! We don't currently have them at our Aquarium, but we have housed them in the past.
Black sea nettles (Chrysaora achlyos) are very mysterious. Except for periodic appearances in California ocean waters, the distribution of this jelly is largely unknown. It does occur in Baja California, Mexico (Isla San Quentin). Up to May 2015, the most recent appearances were in 2010 and 2012 in San Diego, California, waters and 2013 in south Laguna waters.
The reproductive cycle of this jelly in the in the wild is not known. A collaborative team of researchers from several aquariums and the University of California at Berkeley has been successful in propagating the jellies in laboratory settings. When the jellies swarmed in local waters in 1999, reproductive systems of adult males and females that washed ashore were sampled. Sperm and eggs incubated together for 24 hours produced swimming planulae (larvae). These settled to become polyps that cloned non-motile polyps. Eventually, strobilation took place and ephyrae were released that became mature medusae.
This jelly has symbiotic relationships with both larval and juvenile crabs (Cancer sp.) that travel with the jelly host until the crabs are ready to become bottom dwellers. The crabs have been observed consuming detritus-laden mucus from the oral arms. Larval and juvenile forms of the Pacific butterfish, Peprilus simillimus, have also been observed swimming behind the bell close to the oral arms into which they could swim to escape danger.
Last fun fact, the black sea nettle was the largest invertebrate given a scientific name in the 20th century and that did not occur until 71 years after it was discovered.
Thanks for asking us about the black sea nettle! If you're interested in knowing more, click the photo to read our Online Learning Center entry about this species.
I read Jellyhead last night and desperately needed to draw the mc (made her a chrysaora achlyos and a fem bc my bsf insisted). Second ver. in the works, but I hope you like it. I really love your writing💫
YOOOOOO
She came out so goood! She looks like she's wearing a big, puffy dress and the tentacles are so well blended! And the ruffle detail on the oral arms! Her hair! I love her hair it goes so well with the rest of the design!
She looks so elegant and perfect for floating aimlessly around in an oversized tank while bumping into things like nobody's business.
Here is the first batch of name changes! We've got the childhood friend, Mizutsuki Sui (formerly Mizunami Haruto) and the brooding Irakusa Achlys (Formerly Irakusa Akuros)
I'll put the name etymology under the cut for those who are interested ^-^
Mizutsuki uses the kanji 水(mizu) "water" and 月(tsuki) "moon"
Sui uses the on'yomi reading of the kanji 水(sui) "water"
Additionally, the name for the moon jellyfish in kanji can be written as 水水月.
Irakusa uses the kanji spelling of the stinging nettle 刺草(irakusa), which is the English namesake of the Chrysaora achlyos (Black Sea Nettle)
Achlys (アキリス) is the Greek personification of sorrow as well as the "Mist" blinding mortal eyes upon death, as well as the namesake for the scientific name of the Black Sea Nettle.
Need more ice and fire after last night? We've got an encore with our black sea nettles and purple-striped jellies! No dragons though.
We’re very excited to display these two species together—with overlapping ranges in the wild, this gelatinous song of ice and fire is being sung in our exhibit hall once again! It’s been years of diligent work on the part of our jelly aquarists to raise black sea nettles (Chrysaora achlyos) and purple-striped jellies (Chrysoara colorata) from scratch behind the scenes. Thanks jelly aquarists!

> Quick fact & image I based it off of below
The bell can grow to be up to 1 meter in diameter and the oral arms can grow to be 5-6 meters long.
