A dainty dancer drifts delicately atop a marvelous mauve medusa. In the wild (and in our exhibit), the larvae of Achelata lobsters drift through the deep sea, riding currents, searching for food, and sometimes even catching a ride on jellies. ♨️

Lobster moth caterpillars, pupa, and adult moth, Stauropus fagi, Notodontidae (Prominent Moths)
This species is named for the crustacean-like appearance of the caterpillar. The arching pose shown in many of the photos above is their threat display. Found throughout Europe and much of Asia.

regular lobsters start out as just little lobsters but spiny lobsters start out as these beautiful weird larvae that also evolved to ride on top of jellyfish. This jellyfish is too small though!!!

Phylum Round 2
Tumblr media
Annelida: Segmented Worms. This group includes earthworms, leeches, and many classes under the umbrella of "polychaete". This diverse phylum encompasses deposit feeders (eating dirt), detritivores, scavengers, deadly ambush predators, filter feeders, parasites, herbivores, and more. They are broadly defined by their repeating body segments and parapodia, which are nubby appendages used for both movement and breathing. Some have curved jaws for catching prey or scraping detritus off of rocks, while others have wide, elaborate feather-like fans for filter feeding. While able to crawl freely, a majority of marine Annelids spend most of their time in self-built tubes or burrows. Among their many important functions, they play a key role in mixing soil/sediment, breaking down decaying organic matter, and providing a key food source to countless other animals.
Cycliophora: An incredibly specialized phylum, the Cycliophorans consist of a single genus. These animals live exclusively on the mouthparts of lobsters. Yes, all Cycliophorans. This is considered a commensal relationship, as the lobster is not harmed by the Cycliophorans' presence. This phylum has an interesting reproductive strategy involving cloned dwarf versions of the male, embryos that drain all nutrients from the mother, and larvae that must be strong swimmers to hopefully re-colonize the host lobster's new exoskeleton whenever it molts.

THE PLANKTONIC DENIZENS OF SIDE ORDER
As a marine biology hobbyist I ADORE the fact that all the spire denizens are planktons. Please enjoy some funky fellows:
crab zoea
Tumblr media Tumblr media
young medusa-stage jellyfish (same life stage as the familiar jellies in Inkopolis and Splatsville, presumably fresh off the ephyra stage of growth)
Tumblr media
amphipod or lobster larva
Tumblr media Tumblr media
ostracod
Tumblr media Tumblr media
a young pteropod, most likely (sea angels are part of this group!)
Tumblr media Tumblr media
I think this weird-horse-looking one is supposed to be an oceanic water flea? I'm the most stumped on this dude
Tumblr media Tumblr media
And of course our lucifer shrimp Cipher!
Tumblr media Tumblr media
Now I can't find any photos online, but throughout various levels of Side Order I also noticed jellyfish ephyra and polyps, and nematodes or perhaps larval flatworms? Even baby cephalopods are considered plankton! (iykyk)
Plankton are often the most basic trophic level in marine environments, providing stability and order to the ecosystem; if there's an imbalance in their population, that causes a butterfly effect among many other types of sealife. They're the perfect choice for Marina's Memverse.

Ethics aside, with how fascinated people are by stupid colored lobsters combined with how lobsters are in no way endangered why haven't people attempted to breed for the coloration?
Lobsters don’t breed well in captivity. They have a larval phase where they have to float around in the open ocean as plankton and that’s sort of hard to replicate properly in captivity.
However, the two baby lobsters that we have (collected last year as larva for a study on molting, now used for education and display purposes) are blue, and we believe it’s because of dietary reasons! Basically, something they eat in the wild would turn them more red/brown and since these two aren’t getting it, they’ve stayed the more blueish green of a larval lobster. So you can’t breed blue lobsters, but apparently you can grow blue lobsters if you get them young enough.
Of course, since they’re only a year old, we have no way of knowing if this dietary issue will hurt them long-term, so I don’t recommend commercializing it just yet.

Bro what is that crab creature with the jellyfish hanging off of it in the deep sea creature post??? It is fantastic!!
Tumblr media
Sorry for the crazy late response on your question, but I believe this is what you’re referring to, and it is a lobster larva holding onto (and probably munching on) 4 Acorn Worms! 🦞 Original Photo by Steven Kovacs

Plankton, a composite image by Roman Vishniac published in LIFE magazine in November 30, 1953.
Caption (note that this was split equally across two pages, and if anyone has a better ID for the critters let me know):
Plankton, the basic food store of the sea, encompasses an immense variety of small floating plants and animals. The more important specimens are shown here without regard to true scale. Most are microscopic, although the largest, the bell-like medusa at bottom of left-hand page, is two inches long. They include: a diatom (straight yellow rod near center of right-hand page); radiolarians and foraminifera (small circular shells to left of diatom); a dinoflagellate (pick-shaped object in lower center of left-hand page); a copepod (above the dinoflagellate); a shrimplike mysid (to right of copepod); a “flying” snail (top, center of left-hand page); sea worms, one with two egg sacs (near upper left-hand corner) and one with tentacles (upper right-hand corner); sea “spiders” (left-hand page, center right and upper right corner); young fishes (right-hand page, left center and top center); larvae of sea urchin (V-shaped object below fish) and of spiny lobster (next to tentacle worm at upper right).

Of the bugs that molt, do they have increased motion/running when they're getting ready to molt, similar to some reptiles?
bugs that molt = Ecdysozoa = arthropods, nematodes, velvet worms, tardigrades, some other weird little guys. I don’t really know how any behave firsthand except for the arthropods I’ve kept.
sort of depends on the species but in many cases it’s precisely the opposite. tarantulas actually flip on their backs and remain motionless for hours prior to molting, centipedes get very stiff (and turn yellowish due to the new cuticle separating from the old) in premolt and in my experience tend to fast for a good few weeks before ecdysis. millipedes even more so; they’ll burrow as deep as they can and might not come up for another month, sporting a fresh new exoskeleton. some mantises might not move for a day or more if they find a good spot to hang to molt, and like many insects anchor their feet in place before molting so that they can cling to good solid footing—their own exuvia—as they emerge.
Tumblr media Tumblr media
(Scolopendra hainanum between molts and one in premolt, with the old yellowed exoskeleton separating)
isopods with their weird biphasic molt are different, and besides the actual process of shedding + 10-30 min of drying, they just get on with their lives before and after. they have it easy! same with things like maggots and other soft-bodied larvae, their exoskeletons are basically thin cellophane and are easy to wiggle out of and it doesn’t slow them down much.
for some aquatic arthropods it’s a bit different, Triops molt by thrashing themselves out of their old skins & it only takes a few seconds sometimes! but for other aquatic creatures with more well developed shells, like lobsters and big crabs, molting is quite laborious and lengthy even with the added support of water.
Tumblr media Tumblr media
(Porcellio laevis “Dairy Cow” with his anterior exuvia, Scolopendra hainanum the middle of ecdysis w/ respiratory tract lining “strings” visible)
molting for reptiles literally is shedding some skin, but molting for arthropods is shedding a skeleton and then some! since a soft new exoskeleton is grown beneath the old one, but before it’s shed the animal has to sit inside a now too-small, very rigid suit of armor, I would assume the general pattern is for arthropods to move less before molting. the lining of the respiratory tract and some of the other internal organs that are part of the cuticle also get molted, plus legs/appendages can get stuck in molt, so also best to find somewhere safe and not leave until hardened up!
a good example of this might be cicadas, which emerge from the ground as nymphs, climb to find a perch, and then don’t move at all except for the muscular contractions needed to break free of the exuvia. that’s why cicada shells are often posed in curious ways—they’re a snapshot frozen in time of a cicada’s last moments as a juvenile.

@meme-lorbius I redesigned chis-A yayyyyy ty for suggesting them
Explanation for the design:
I was really searching for a theme to base her on but I thought her og hair looked kinda like what’s called a jellyfish hairstyle and her skirt looked kinda sea like? So I went with that. I fleshed out the sea theme with some seaweed and coral colors, some sea lilies and sea glass gems. I gave her vitiligo to mimic the way coral looks when it turns white. Those little things that kind of look like ears on her hair are based on some squid who have similar looking parts. They also are meant to represent gills. Their color palette is basically her old one but brighter and prettier. She has a pet, based on lobster larvae who ride on jellyfish. I have yet to draw it but i will soon and I will need name suggestions.

110-million-years-old fossil suggests early parasitism in shrimps
Tumblr media
Direct evidence of paleo-parasitism in crustaceans is very scarce. Epicaridean isopods are obligatory parasites of crustaceans, including decapods such as crabs, shrimps, and lobsters. Their interaction with hosts is known from fossils as far back as the Jurassic through deformations of the branchial cuticle on the hosts. Their small size and low fossilization potential, outside of those larvae that have been found in amber, makes understanding the group’s evolution challenging. Here, we report the oldest evidence of paleo-parasitism in marine shrimps and an imprint of a putative adult parasite that appears to be an epicaridean isopod. Our results suggest that the parasite–host interaction between epicaridean isopods and marine shrimps started at least 110 million years ago, and the Tethys Sea was a possible dispersal pathway for this lineage of parasites during the Jurassic and Cretaceous, as known for other marine organisms through most of the Mesozoic and Cenozoic. The oldest fossil records of bopyrid swellings associated with a large number of decapods from the Jurassic in Europe suggest that the Tethys region was a center of epicaridean distribution as a whole. Recent parasitic isopods found on dendrobranchiate shrimps are restricted to the Indo-Pacific and may represent a relict group of a lineage of parasites more widely distributed in the Mesozoic.

Opinions on the new Splatoon character featured in the upcoming Side Order update? (no idea what it is)
Oh my god is that a LUCIFER???!?!!!
......As in an obscure genus of darkness-dwelling planktonic crustaceans!
Tumblr media Tumblr media Tumblr media
There are other transparent marine crustaceans with stalks eyes, like this mantis shrimp larva and spiny lobster larva:
Tumblr media Tumblr media
...But Splatoon friend really emphasizes stalk-eyes as THE standout feature on an otherwise plain skinny body, and if they based a character on a larva I might expect it to be more kid-coded, though you really never know how Splatoon might decide to stylize a given animal. Also I say "darkness dwelling" because not all creatures like this are just "deep sea." Lucifer stay fairly deep during the day but they rise almost to the surface at night, as do lots and lots of other sea creatures. They just go where the dark goes! UPDATE apparently the character outright shares the lucifer shrimp's Japanese name, dream-shrimp!

Gnathostomulida: Jaw Worms. All animals in this phylum are "meiofauna", meaning they live in the spaces between grains of sediment on the seafloor. They are covered in hair-like cilia, which aids in navigating their micro-environment. As the name implies, they have a strong set of jaws, often with tiny teeth for grinding food. They are hermaphroditic, and strangely, each "lays" a single egg that breaks through the parent's body wall and adheres to a nearby grain of sand. Thankfully, the parent is able to quickly heal from this wound. These animals are important for maintaining chemical cycles between the sediment and water above, and they are a rich food source for higher organisms in the bottom-dwelling food chain. They are also very sensitive to pollution, making them important "bio-indicators".
