Round 2.5 - Cnidaria - Cubozoa

(Sources - 1, 2, 3, 4)

Cubozoa is a class of cnidarians commonly called “box jellyfish.” There are two orders within the class: Carybdeida and Chirodropida. It is the smallest cnidarian class with roughly 50 species known, though it is likely many more remain undescribed. Cubozoans are infamous for some species having extremely painful and even fatal stings, though many species are not dangerous to humans.

The medusa form of a box jellyfish has a squarish, box-like bell, from which its name is derived. From each of the four lower corners of this hangs a short pedalium or stalk which bears one or more long, slender, hollow tentacles. The rim of the bell is folded inwards to form a shelf known as a velarium which restricts the bell's aperture and creates a powerful jet when the bell pulsates. As a result, box jellyfish can move more rapidly than true jellyfish, and speeds of up to 6 metres (20 ft) per minute have been recorded. The Cubozoan nervous system is more developed than other cnidarians with a ring nerve at the base of the bell that coordinates their pulsing movements. Uniquely, Cubozoans are also the only cnidarians to have true eyes, complete with retinas, corneas and lenses. Their eyes are set in clusters at the ends of sensory structures called rhopalia which are connected to their ring nerve. Each rhopalium contains two image-forming lens eyes. The upper lens eye looks straight up out of the water. In species such as Tripedalia cystophora, the upper lens eye is used to navigate to their preferred habitats at the edges of mangrove lagoons by observing the direction of the tree canopy. The lower lens eye is primarily used for object avoidance. Each rhopalium also has two pit eyes on either side of the upper lens eye which likely act as mere light meters, and two slit eyes on either side of the lower lens eye which are likely used to detect vertical movement. In total, the box jellyfish have six eyes on each of their four rhopalia, creating a total of 24 eyes. Due to this complex nervous system and relatively advanced sensory system compared to other cnidarians, box jellyfish display active, visually-guided, fishlike behavior, rather than drifting on the currents like true jellyfish.

The venom of cubozoans is distinct from that of scyphozoans, and is used to catch prey (small fish and invertebrates, including prawns and bait fish) and for defense from predators. They feed by extending their tentacles and accelerating for a short time upwards, then turning upside-down and pausing their pulsating. Then the jellyfish slowly sinks, until prey finds itself entangled by tentacles. Each tentacle has about 500,000 cnidocytes, containing nematocysts, a harpoon-shaped microscopic mechanism that injects venom into the victim upon contact. Many different kinds of nematocysts are found in cubozoans. When prey is tangled in the tentacles and the nematocysts have fired into it and stunned or killed it, the pedalia folds and brings the prey to the oral opening.

Chirodropida reproduces by external fertilization and Carybdeida reproduces by internal fertilization and is ovoviviparous; sperm is transferred by spermatozeugmata, a type of spermatophore. Hours after the fertilization, the female releases an embryo strand that contains its own nematocytes. Cubozoans are the only class of cnidarian that contains species that perform a “wedding dance” to transfer the spermatophores from the male into the female.

Cubozoans have been around since the Middle Cambrian.

Propaganda under the cut:

Often described as “the most lethal jellyfish in the world” the Australian Box Jelly or “Sea Wasp” (Chironex fleckeri) is responsible for 64 known deaths in Australia from 1884 to 2021. Being stung commonly results in excruciating pain, and if the sting area is significant, an untreated victim may die in two to five minutes. The amount of venom in one animal is said to be enough to kill 60 adult humans. It is also the largest Cubozoan, with body sizes reaching up to one foot in diameter and thick, bootlace-like tentacles up to 10 feet long.

Irukandji Jellyfish are any of several similar, extremely venomous species of rare box jellyfish. With very small adult sizes of about a cubic centimetre, they are both the smallest and some of the most venomous jellyfish in the world. There are about 16 species of box jellyfish called Irukandji, of which Carukia barnesi, Malo kingi (image 3), Malo maxima, Malo filipina and Malo bella are the best known. People stung by these may suffer severe physical and psychological symptoms, known as Irukandji Syndrome. Nevertheless, most victims do survive.

Wearing pantyhose, full body lycra suits, dive skins, or wetsuits are an effective protection against box jellyfish stings. The stinging cells on a box jellyfish's tentacles are not triggered by touch, but by chemicals found on skin, which are not present on pantyhose or the outer surface of wetsuits, so the jellyfish's nematocysts do not fire. If a tentacle of a box jellyfish does adhere to skin, it automatically pumps nematocysts with venom into the skin, causing the sting and agonizing pain. There is no scientific evidence that urine, ammonia, meat tenderizer, sodium bicarbonate, boric acid, lemon juice, fresh water, steroid cream, alcohol, cold packs, papaya, or hydrogen peroxide will disable further stinging, and these substances may even hasten the release of venom. However, flushing with vinegar can be used to deactivate undischarged nematocysts and prevent the release of additional venom.

Sea turtles, including the hawksbill sea turtle and flatback sea turtle, are unaffected by box jellyfish stings and specialize in snacking on them.

High school marine biology teacher Lisa Peck won an online competition to name the Bonaire Banded Box Jellyfish Tamoya ohboya (image 2), because, she said "I bet ‘Oh Boy!’ is the first thing said when a biologist or layman encounters the Bonaire Banded Box Jellyfish." It has orange and white striped tentacles. Oh boy!

The tiny (1 cm [0.4 in] wide) Mangrove Box Jelly (Tripedalia cystophora) is harmless to humans and feeds on copepods. They are threatened due to habitat destruction.

They have eyeballs for goodness sakes. Why do they have eyeballs. Who gave them the right.

These are amazing, ancient Cambrian creatures that have existed in the seas long before us and will be here long after we are gone. They are smarter than other jellyfish, smarter than we give them credit for, and they are not out to get us. We are not their prey. We are land animals and they are sea animals. If we’re going to keep entering their hunting grounds then it’s up to us to figure out how to adapt to live alongside them.

The 2nd Character Design Tournament

Please remember to vote for characters solely based on their design, rather than which character you are more familiar with or like more!

*One of the characters in this bracket is considered a spoiler for: One Piece

*Additional warning for spoilered propaganda for: Monkey D. Luffy

Cool Spot | Cool Spot 1993 Console Game & 7Up Logo

“It's so simple it's sort of genius. The 90's were a different time.”

Monkey D. Luffy (Gear 5) | One Piece

“Freedom. That is the design philosophy behind this character.”

“Really good union of Luffy's original classic character design and the new gear 5 elements. His already cartoony personality and fighting style is enhanced by the ability to make himself bigger and make his eyes pop out like wile e coyote.”

*Spoilered propaganda for: Luffy | One Piece

“Luffy, completely shattered from his fight against the oppressive Kaido, finally awakens the power of the Sun God Nika. Most transformations are about power, despair, and rage. But this is about creativity. This is liberation. This is joy. This is why he is the reincarnation of Joy Boy.”

“Luffy's bouncy cloud hair really works to signal Nika/Joyboy's dynamic personality.”

Maybe unpopular opinion? I'm not a big fan of the new logo, and especially how it all looks for the merch

It just feels way too simplified and feels like the equivalent of brands simplifying their logos down to basic stupid shapes because "hur dur graphic design"

リニューアルして生まれ変わった神戸のアイコン、ポートタワーの展望３Fのカフェ、Ready go round （レディーゴーラウンド）と1Fの裏側にあるReady go round miniのロゴデザイン、ワックスペーパー、ソフトクリームラッピングなど、デザインさせていただきました。ネオンに映えるデザインを意識しております。神戸の海と山と都市を一望できる展望カフェは今でも回る。昔は回転レストランとかはいくつかあったはずだけど現存しているものはわずかなはずなので、その観点で見ると面白いかなと思ったり。Ready go round miniの目玉は暗闇で光るブリリアンスパウダーのソフトクリーム！
