Can you draw the littlest guy... Morbakka virulenta.............

My first in getting jellyfish art requests! Finally, I hope I did Morbakka Virulenta some justice! Didn't have coloured pencils, but was too excited to not do! Thank you so much!

I am back!

sorry for deleting my old stuff, but I didn't think anyone would care nor notice. But here I am, with new motivation!

Hmm.... why *do* we call them sea jellies?

Got any cool jellyfish facts?

Of course!

These are my favorite jellies of the day, the flower hat jelly.

Flower hat jellies have a translucent bell with dark, opaque pinstripes radiating from the top center to the edge. Lustrous, multicolored, fluorescent- tipped tentacles trail from the bell, with others coiled up close to their bodies, making them appear short. They appear to light up like fireworks under a black light.

Fish of the Day

Today's fish of the day is the flower hat jelly!

The flower hat jelly, scientific name Olindias formosus, is a small and rare jelly known for the multicolored tentacles and luminescent display. Belonging to the hydrozoa family, the flower hat jelly is not actually a true jellyfish. The main difference between them being that true jellyfish belong to the Scyphozoa class, and have a life cycle defined by a longer period as a medusa (their adult form) whereas hydrozoans have a lifecycle primarily defined by their polyp or juvenile stages, sometimes even lacking medusa forms, a pattern that can once again be found in the flower hat jelly's life cycle. Their distribution is off the coastline of Japan, Korea, and countries within Oceania. Although some believe that these jelly's can also be found outside of Argentina, and Brazil, it is thought this may be a close relative, Olindias sambaquiensis. With a depth range from sea level down to 55m of depth, these jellyfish tend to live near the ocean floor where they can hide among kelps, sea grasses, and loose rocky bottoms.

Living a nocturnal life, the flower hat jelly spends its days hiding on the ocean floor. But, once dusk arrives this jelly rises from its hiding places to capture small fishes within its tentacles, paralyzing and or killing the fish, before drawing the corpse up into the bell to be consumed. The stings from this jelly are painful, and at least one fatality has been recorded from them in Japan.  These tentacles hold most of the intrigue of the flower hat jelly.  The length of the tentacles may appear to be random, but has been found to be arranged mathematically in an optimization hashing algorithm known as fibonacci hashing. Length aside however, these jelly's, and especially their tentacles contain fluorescent proteins, which are used to attract prey when hunting, and are particularly bright under blacklight. This protein is uniquely interesting due to its use in helping treat some COVID cases, as it can be used as an inhibitor, stopping the replication of the disease, and slowing or halting its spread.

The reproduction and younger stages of the flower hat jellyfish were a mystery for many years, but in 2012 the Monterey Bay Aquarium managed to be the first to breed them in captivity, capturing a full lifecycle from larvae to polyp to medusa. Beginning as polyps attached to a hard surface along the seabed, where they are completely stationary, surviving off of a single active tentacle, which is waved back and forth to gather nutrients, forming a medusae and releasing them only once a size of 1mm was achieved. Then they will mature into juvenile medusa, which are identical to adult medusa in appearance and behavior, only being identifiable by their smaller size and less tentacles. Juvenile medusa only being around 2-20mm, and adults getting only as large as 6inches total throughout their lifespan. Adult flower hat jellies are only observed in the months of December-July with peaks in the months of May and April. However, we understand very little about how these jelly's sexually breed in the wild, but fertilization occurs externally, as gametes are released into the water to create small, non-cooperative colonies along similar areas. These animals live only 4-6 months as adults, and only around a year total before slowly losing their fluorescence and passing away.

That's the flower hat jelly, everybody, have a wonderful Tuesday!

🪼Daily Cnidarian Fact:🪼

Flower Hat Jellyfish: Flower hat jellies are nocturnal and remain on or close to the sea bottom during the day. They are found off of southern Japan, Argentina, and Brazil. Although they look like a jellyfish, they actually belong in the class Hydrozoa, while true jellyfish belong in class Scyphozoa. The adult form of the flower hat jelly only lives a few months and is typically seen from December to July, with peaks in April and May.

Reminder to all my jellyfriends that hydrozoan and cubozoan jellyfish are true jellyfish too :)

The distinction between Scyphozoa, Hydrozoa, and Cubozoa- while morphological and pronounced- are not different enough for them to be disqualified from the term. In any case, they mainly fill the same ecological niche (especially Scyphozoa and Hydrozoa) and have vaguely the same body structure, so you can’t really call the other two “fake jellyfish”

Jellies are trending 🙌🏼⁠

Everyone is familiar with the basic idea of a jellyfish, but what do we mean when we use that term? Jellies in the class Scyphozoa include most of the species that people think of when hearing the word “jellyfish.” Their life cycles typically include a polyp stage, attached to the bottom, that produces baby medusae. When conditions are right, these babies can grow up to form vast blooms of adult jellies. These "true jellies" are commonly studied at the sea surface, but those living deep in the water column are less well known. Some deep-sea jellies defy what we imagine when we think of jellyfish—some with bells that can stretch up to a meter across, others with no tentacles at all. ⁠ ⁠ Many species of swimming jellies are actually in another group called the Hydromedusae. These jellies are often small and transparent, ranging from very few to numerous tentacles. Some Hydromedusans have tentacles that point ahead of them instead of trailing behind them as they swim. These species eat other gelatinous organisms rather than the crustaceans favored by many of their cousins. Even with all this dazzling diversity, we have yet to encounter many of the delicate drifters that live in the deepest waters of our vast ocean. ⁠
