Do u see how the mountain dwellers treat me

[somewhereincairparavel]

'i hate jason grace because he thought he was worthy enough to compete with percy' I'm sorry have y'all SEEN jason. this man defeated a TITAN without weapons and his bare hands to the point the titan wanted to rise from the UNDERWORLD with the help of a GODDESS to seek vengeance over him. I think we can cut him slack for having some well deserved self respect bc I'd brag too wtf

Humans are often inclined to build seawalls to protect coastal communities from encroaching oceans, but those require constant, expensive maintenance. And in fact, the way we’re changing land, rivers, and climate—and even the seawalls themselves—are undermining natural protections, such as tidal marshes, barrier islands, coral reefs, seagrass beds, dunes, gravel beaches, and kelp and mangrove forests. If left intact, these natural communities can slow fresh and tidal water, acting as a buffer, providing flexible and resilient protection for human communities. They provide multiple co-benefits, and even have the ability to sustain themselves. With these abilities, they can reduce by half the number of lives and properties at risk from storm surges and sea-level rise, according to a study in Nature Climate Change. Unlike seawalls, tidal marshes have a superpower against sea-level rise. It’s not just that they are a buffer between the water and human infrastructure, sapping energy from storm surges and blocking the highest tides. Marshes can actually grow vertically, keeping pace with sea-level rise by trapping sediment in their vegetation, which decomposes and then regrows. To perform this trick, they need three ingredients: sediment, space, and time.

[...]

Broadly speaking, human development has erased many of water’s slow phases—floodplains, meadows, forests, and wetlands, such as tidal marshes. For example, humans have eradicated 87 percent of the world’s wetlands. What water wants, say the detectives, is a return of these slow phases, an approach I think of as the “Slow Water Movement.” Slow water approaches are unique to each place, work with local systems, are distributed rather than centralized, are socially just, and empower and engage the local community. They also provide multiple benefits beyond buffering us from flood and drought, including carbon storage and homes for threatened plants and animals.

An old voracity lives here, in the far reaches of the zee. The priests are long gone, but sacrifices are still made. Perhaps you have come here to make a sacrifice. Perhaps the sacrifice is you.

Round 3 - Chondrichthyes - Myliobatiformes

(Sources - 1, 2, 3, 4)

Our first order of rays are the Myliobatiformes, or “Stingrays.” This order includes the families Zanobatidae (“panrays”), Hexatrygonidae (“Sixgill Stingray”), Dasyatidae (“whiptail stingrays”), Potamotrygonidae (“river stingrays”), Urotrygonidae (“American round rays”), Gymnuridae (“butterfly rays”), Plesiobatidae (“Deepwater Stingray”), Urolophidae (“round rays”), Aetobatidae (“pelagic eagle rays”), Myliobatidae (“eagle rays”), Rhinopteridae (“cownose rays”), and Mobulidae (“devil rays”).

Myliobatiformes are characterized by their enlarged, expanded pectoral fins being completely fused to their head and body, called a “disc”. Their disc shape ranges from diamond to subrhombic to lozenge-shaped. They are also characterized by the presence or absence of a single small dorsal fin, a long whip-like tail, and one or more stinging spines on the upper tail base (some species have secondarily lost this spine). As a defense mechanism, stingrays will flail their pointed or barbed tails and lodge the spine within a potential predator while they escape. The spine eventually grows back. As rays, their eyes and spiracles are on the dorsal side of their body while their gill slits, nostrils, and mouth are on the ventral side. Most myliobatiformes have blunt, pavement-like teeth for crushing hard-shelled prey and bony fish, though Manta Rays are planktonivore filter-feeders. They give birth to live young, usually 1-10 per litter, depending on species. This is a highly diverse group, and the second largest order of batoids (rays).

Myliobatiformes arose in the Early Cretaceous.

Propaganda under the cut:

Most stingrays are not aggressive if left alone, and some are even curious and friendly. The Cownose Rays (Rhinoptera) especially are known for this behavior, and are often the species of choice for touch tanks in public aquariums, as they will actively seek out attention. In my family’s experience, my sisters and mother were swimming in the ocean two Summers ago, and my sister patted what she thought was my mom’s foot after it bumped her on the back. She then realized it was a Cownose Ray (Rhinoptera bonasus) when another one tripped my other sister! A school of them was playing in the shallows and had decided to mess with my family. (I only ever get pinched by crabs and spooked by jellies when I enter the ocean ;_;)

Uniquely for its family, the Porcupine Ray (Urogymnus asperrimus) lacks a venomous tail spine. Instead, it defends itself with the many large, sharp thorns found over its disc and tail. Due to its thorny hide, this now endangered ray has historically been a very valuable source of shagreen.

The Giant Oceanic Manta Ray (Mobula birostris) is the largest stingray, growing up to 9 m (30 ft) long, 7 m (23 ft) wide, and weighing about 3,000 kg (6,600 lb), though the average size commonly observed is half that.

Around 35 cm (14 in) in width, the Bluespotted Ribbontail Ray (Taeniura lymma) is one of the most venomous species of stingray and is known to have an excruciating sting. Nevertheless, it is popular with home aquarists for its small size and beautiful coloration. Despite this, it is not well suited for captivity, being a very shy species and prone to refusing to feed. Seldom have hobbyists been able to keep one alive for long in home aquariums. Professional, public aquariums have had much better luck with the species, even maintaining breeding programs.

The composition of venom in freshwater stingrays appears to differ from that of marine stingrays.

Stingrays that live in the deep sea, such as the Deepwater Stingray (Plesiobatis daviesi) and the Sixgill Stingray (Hexatrygon bickelli) are flabby and almost goopy, with a skate-like appearance. The deep sea changes folks.

When threatened, the Crossback Stingaree (Urolophus cruciatus) raises its tail over its disc like a scorpion, as a warning.

Spotted Eagle Rays (Aetobatus narinari) sport 2-6 venomous, barbed spines at a time, but the most danger they have presented to humans so far is via their leaping from the water at the wrong place/wrong time! On at least two occasions Spotted Eagle Rays have been reported as having jumped into boats, and in one incident this sadly resulted in the death of a woman in the Florida Keys. Otherwise, these rays appear to be curious about humans and will sometimes slow down to inspect snorkelers if the human is not acting threatening.

The Chilean Devil Ray (Mobula tarapacana) is one of the deepest-diving ocean animals, traveling from the surface to feed at depths of up to 1,896 metres (6,220 ft). A veined structure of blood vessels warms the ray's brain at colder depths. These rays stay near warmer surface water for at least an hour both before and after deep diving, suggesting that they are soaking up heat to prepare for and recover from their descent into colder water.

Manta Rays (genus Mobula) are incredibly smart. They were the first “fish” in the world to pass the “mirror test” (ie show self-awareness by recognizing themselves in a mirror rather than seeing the reflected image as another manta ray). They also have highly-developed long-term memory, form friendships, and play with each other by blowing bubbles and breaching out of the water.

Steve Irwin’s death was a freak accident. He was swimming and passed overtop a 2 m (6.7 ft) long Short-tail Stingray (Bathytoshia brevicaudata), and the animal reacted reflexively to his shadow by stabbing its barbed tail repeatedly into what it perceived as a predator. By an insane stroke of bad luck, the spine from the stingray’s tail pierced right through into Steve’s chest. (And no, the barb did not become lodged and he didn’t pull it out; that’s a rumor. Venom or no, there’s not much you can do about being stabbed in the heart.) Fatal stings are very rare, and only around 20 stingray-related deaths have been recorded in history. Steve loved all animals and would not have wanted people to hold his death against literally all species of stingray, let alone the single one that accidentally took his life. Even as a joke, using Steve Irwin to hate on an animal does a great disservice to his legacy. So if I hear a word of stingray-hate in Steve’s name, I’m calling the guards. >:C

Wouldn't Rung implode from the pressure difference like the blobfish did..?

Oh, all deep sea fishes unlucky to be thrown above absolutely imploded with inverted organs, they couldn't orient fast to release the gas inside their air bladder Deep-sea divers specially lift fish slowly so that their blood wouldn't boil and all the gas would come out But Rung always had in canon some more hidden pockets within him, so I imagined that he had extra bladders that immediately reacted on the changed pressure and was compensating the ones that he couldn't change quickly, plus he might not have fastest reflexes but he knows what to do so he started adapting the moment flooding started getting him up. Other deep sea creatures are either not sentient or not even mers, they were caught off guard

But he still starts feeling worse and worse each day due to blood boiling and gas not getting out fully from sudden change pressure once his body starts understanding what happened, so that Nightbeat and Nautica would need to get him back in the deep, which is impossible because of all the new monsters and the fact that Rung's swimming abilities are weak, or they would need to find a medic who knows deep sea mermaids' anatomy and could operate him to help

SEVEN SEAS ENTERTAINMENT PICKED UP PSOH THIS IS NOT A DRILL!!!!!!!!!!!!!

[chromatophorium]

This is an entirely self-indulgent SOMA/Splatoon crossover, haha. (a reworked au, as those who have seen certain other posts of mine may know)

So, helmet/head is a Octocopter helmet. Arms are the hoses of Octotroopers. Legs are the ones of a Octopod. And the internals of the torso is a Octoling Soldier's inktank.
