Медуза компасная.
Chrysaora melanaster (лат.) — вид дискомедуз из рода Chrysaora семейства Pelagiidae, водится в водах Японского и Охотского морей и у тихоокеанских берегов Кур��л. В англоязычных странах также извес��на под названиями северная морская крапива (англ. northern sea nettle) и коричневая медуза (англ. brown jellyfish), раньше ещё одним английским названием вида было название японская морская крапива (англ. Japanese sea nettle), теперь оно используется только по отношению к виду Chrysaora pacifica.
Компасная медуза обладательница длиннющих щупалец, которые вырастают до 4,5 метров и их максимальное количество составляет 24 штуки.Максимальный диаметр зонтика достигает 630 мм. Обитает на глубинах до 100 м, где питается веслоногими ракообразными, аппендикуляриями, мелкими лучепёрыми рыбами, крупным зоопланктоном и другими медузами . Это одиночная, свободноплавающая медуза.
Compass jellyfish.
Chrysaora melanaster (lat.) is a species of disc jellyfish from the genus Chrysaora of the family Pelagiidae, found in the waters of the Sea of Japan and the Sea of Okhotsk and off the Pacific coast of the Kuril Islands. In English-speaking countries, it is also known as the northern sea nettle and brown jellyfish. Previously, another English name for the species was the Japanese sea nettle, now it is used only in relation to the species Chrysaora pacifica.
The compass jellyfish has very long tentacles that grow up to 4.5 meters and their maximum number is 24 pieces. The maximum diameter of the umbrella reaches 630 mm. It lives at depths of up to 100 m, where it feeds on copepods, appendicularians, small ray-finned fish, large zooplankton and other jellyfish. It is a solitary, free-swimming jellyfish.

Northern sea nettle (Chrysaora melanaster)
The northern sea nettle is a species of jellyfish native to the northern Pacific Ocean and adjacent parts of the Arctic Ocean.The medusa of the northern sea nettle can reach 60 cm in diameter with tentacles growing up to 3 m. The number of tentacles is up to 24 (8 per octant). It dwells at depths of up to 100 meters, where it feeds on copepods, larvaceans, small fish, large zooplankton, and other jellies. The sting is mild, although can cause serious skin irritation and burning. The lifespan is unknown

I finally had time this week to get my give-away winner’s request of ‘jellyfish’ finished, but it appears that freerangesquids has been deactivated. If they happen to still stalk this blog, here you go. Sorry it took so long.
I’ve never drawn jellyfish before, but enjoy looking at photos of them. There are so many cool ones out there, I had a hard time deciding what to do. These are an attempt at chrysaora melanaster according to the reference photos I pulled months ago. I picked them because of the stripes.

pictures of a japanese sea nettle (chrysaora pacifica) i took at the london sea life aquarium. they are carnivorous jellyfish, with their diet consisting of other jellyfish, anchovy eggs, zooplankton and copepods. their sting causes skin irritation and feels like a burning sensation and is considered mild.
this species of the genus chrysaora is often confused with their larger cousins, the northern sea nettle (chrysaora melanaster). as such, some specimen in public aquariums are often mis-labeled as c. melanaster.

Question: Is your pfp the Chrysaora hycosella??? 👀👀... I always mix them up with the Chrysaora pacifica and the Chrysaora melanaster because they all look so similar 😭😭.... Also, it seems as if the picture for the Chrysaora pacifica English Wiki is a Chrysaora fuscescens instead of a Chrysaora pacifica... though I might just be mistaking it, haha (I have no confidence at all ;w;) (By the way, I wouldn't use scientific names usually but because these jellies in particular have confusing names, I just stuck to the scientific ones for more clarity ;w;)
Hi
I think it is a Chrysaora hysoscella, but honestly I just trusted the website I got it from. I don't know how to spot the difference between most Chrysaora types... I hope the bigger picture is clearer to inspect
I get most of my information from Wikipedia (which can be flawed indeed) and the jellyfish book from Lisa-Ann Gershwin. I love that book but it is not mentioned there.
You seem to know so much about them, where do you get your info from?

Jellyfish identification reddit my beloved (<- and JellyfishWarehouse my beloved)
#I'm honestly not the best at differentiating between different species but it's ok :)#tbh i'm not 100% sure that the jellyfish was a chrysaora pacifica bc there's usually some reddish pigment in there#but#it's the closest one we've got and the most popular ones kept in aquariums#someone else mentioned the chrysaora quinqincirreha(?) and that seems like a likely option#though usually it is ghostly white and doesn't have the same striking stripes that the image does#it reminds me more of the sea nettles that are found around parts of Africa but I haven't done enough research on them to be 100% sure#chrysaora pseudocelata is such a funny name to me tho#um#anyways I should rly learn how to differentiate octants in a jellyfish#because that's like the number 1 way to differentiate between species#they are radially symmetrical so they have 8 parts#number of tentacles is surprisingly important too#the chrysaora pacifica (japanese sea nettle) has 40 tentacles while the chrysaora melanaster (northern sea nettle) has 24#the difference is also pretty staggering with the closely related chrysaora achlyos and chrysaora colorata (black sea nettle and purple str-#-iped sea nettle respectively). can't remember which one has more but my bet is on the c. achlyos#mun rambles#jellyfish#chrysaora pacifica

For no reason in particular I have a chart full of Jellyfish ephyra and if I have to go by the chart, my best guess is that this is the Chrysaora pacifica (just by virtue of it being a Japanese/American documentary and also the markings lining up, imo. That could be just the lighting tho)
apparently the C. pacifica and the C. melanaster were commonly mixed up too in aquariums so it's possible that the documentary might've also gotten it wrong(?). I don't think I've watched this before so it's all pure conjecture
Unknown, Japanese/ American nature documentary, life in oceans, 1970s
#I'm not 100% sure but this is my best guess hehe#I love ephyras their little nubs are so cute. Heart emoji#Box jellies have an odd lifecycle tho I should probably study that too 😅😅. Don't know too much ab them#I say odd but it's just slightly different from scyphozoan life cycles#reblog#jellyfish#mun rambles#if anyone wants jellyfish baby pictures I'm more than happy to show them off lol#I even got polyps just take your pick

Imágenes insólitas de una medusa capaz de vivir al invierno ártico
Nuevo artículo publicado en https://www.prozesa.com/2017/11/04/imagenes-insolitas-de-una-medusa-capaz-de-vivir-al-invierno-artico/
Imágenes insólitas de una medusa capaz de vivir al invierno ártico
A través de un pequeño robot submarino, un grupo de investigadores de la Universidad de Columbia han capturado una extraña secuencia de medusas árticas deslizándose a lo largo del fondo del mar de Chukchi, cerca de Barrow (Alaska). La filmación fue una completa sorpresa para los investigadores, que no esperaban ver medusas durante el invierno ártico. La investigación, publicada en Marine Ecology, muestra cómo una especie de gran medusa conocida como Chrysaora melanaster es capaz de sobrevivir al invierno ártico en su forma adulta, una etapa de la vida conocida como medusae. Antes de estas observaciones, realizadas entre el 2011 y 2014, se pensaba que las condiciones bajo el mar eran demasiado duras para las medusas adultas durante los meses de invierno, y que esta especie solo podría sobrevivir bajo el hielo ártico durante su etapa como pólipo, un invertebrado marino que libera pequeñas medusas bebé en la primavera. https://youtu.be/bcACUxJ_DtM Para capturar la secuencia, el biólogo marino Andy Juhl y sus colegas del Instituto Earth de la Universidad de Columbia partieron en motos de nieve desde Barrow, Alaska, a varios lugares a lo largo del mar congelado de Chukchi. Después de perforar agujeros a través del hielo de más de un metro, los investigadores enviaron un pequeño vehículo submarino con una cámara a través de las frías aguas. Para su asombro, el sumergible capturó imágenes cautivadoras de estas enormes medusas, algunas de ellas arrastrando sus tentáculos de medio metro detrás de ellas. Las medusas usan estos tentáculos para arrebatar comida del lecho marino. El trabajo sugiere que la Chrysaora melanaster es capaz de vivir en su forma adulta durante los meses de invierno, y posiblemente incluso vivir durante años. Juhl ahora sospecha que los inviernos fríos en realidad son realmente buenos para las medusas; la gruesa capa de hielo marino puede actuar como un escudo, protegiéndolas de las aguas turbulentas. Mientras tanto, el agua fría va disminuyendo su metabolismo, permitiendo que las medusas subsistan con muy poca comida. “La vida bajo el hielo marino es como vivir en un refrigerador, todo se ralentiza”, dijo Juhl en un comunicado, y agregó que las floraciones de medusas pueden continuar uno o dos años cubiertas de hielo marino porque en su fase adulta sobreviven. De hecho, el área de Alaska investigada está sujeta a cambios drásticos sobre el número de medusas cada año. Algunos años casi no existen, y otros hay tantas que las redes de pesca se inundan de ellas. La nueva investigación podría decirnos algo sobre la dinámica de la población de medusas que impulsa estos ciclos. En un apunte más preocupante, el calentamiento de las aguas causadas por el cambio climático podría ser malo para las medusas del norte, las cuales se benefician de las aguas frías y la capa de hielo (a diferencia de otras medusas que se encuentran entre las mayores beneficiarias del calentamiento global).
