7 Underwater Facts for World Oceans Day

Today is World Oceans Day, a global day of ocean celebration and collaboration for a better future. A healthy world ocean is critical to our survival. Together, let’s honor, help protect, and conserve the world’s oceans!

1. While the Earth’s oceans are known as five separate entities, there is really only one ocean.

2. The ocean contains upwards of 99% of the world’s biosphere, that is, the spaces and places where life exists.

3. Jellyfish are soft because they are 95% water and are mostly made of a translucent gel-like substance called mesoglea. With such delicate bodies, jellyfish rely on thousands of venom-containing stinging cells called cnidocytes for protection and prey capture.

4. Plastics & litter that make their way into our oceans are swiftly carried by currents, ultimately winding up in huge circulating ocean systems called gyres. The earth has five gyres that act as gathering points, but the largest of all is known as the ‘Great Pacific Garbage Patch’ and has grown so immense that the oceanic garbage patch can shift from around the size of Texas, to something the size of the United States.

5. The 200 or so species of octopuses are mollusks belonging to the order Cephalopoda, Greek for ‘head-feet’. Those heads contain impressively large brains, with a brain to body ratio similar to that of other intelligent animals, and a complex nervous system with about as many neurons as that of a dog.

6. Some lucky animals are naturally endowed with bioluminescence, or the ability to create light. The firefly, the anglerfish, and a few more surprising creatures use this ability in many ways, including survival, hunting, and mating.

7. Sea turtles ultimately grow from the size of a dinner plate to that of a dinner table. In the case of the leatherback sea turtle, this can take up to a decade. Happy World Turtle Day!

So like, let’s talk about how Viktor “PDA” Nikiforov is married to Yuuri “I Come From A Culture Where Handshakes Are Not Routine” Katsuki and how that works.

I think the reason we see Viktor’s hand on Yuuri’s shoulder so often is because it’s a safe and established middle ground. It isn’t overt, it’s just a little bit possessive, to satisfy Viktor’s Needs, and there are very few ways that a simple hand on the shoulder can be considered unchaste or overly intimate in a public setting–which Yuuri (Who, again, comes from a culture in which outward displays of emotion are still considered distasteful) would be satisfied with.

I think it also works like this: Viktor is secure in his relationship. He and Yuuri are adults in their mid-to-late twenties. Viktor himself would probably find it distasteful to act like a nineteen-year-old on a couch at a frat party 24/7–that is to say, he’s self-aware and mature enough to understand that he doesn’t have to be connected to Yuuri by various bodyparts at any given time of day.

That’s not to say that Viktor doesn’t Full On Octopus Boy himself around Yuuri at the end of the day. That’s not what I’m saying at all. Viktor bought both a new sofa and a new bed so that he could Become One with Yuuri (in more ways than one) when in the privacy of their own home.

But yeah. I don’t think that Viktor and Yuuri, as a couple, are very PDA-orientated. That’s why I was actually weirdly relieved when I saw the art of them walking side-by-side and not touching, or even looking at each other, because hey. Let me have my conversation and you can look at that weird tree over there–I don’t have to be constantly gazing into your Pale Orbs.

That’s how mature couples work. That’s especially how I imagine a relationship works with someone who’s A: From a chaste culture and B: Is also, just on a personal level, Not About Being Touched All The Time.

They love each other and they don’t have to always be touching in order for that to be expressed. Sometimes, love is in the space that you do give to another person.


Angela, the tiny giant octopus girl.

She used to live in the canals with Meg until one fateful day when everything changed. She’s bitter after having lost all she had. She refuses to speak and she harbors a burning hatred for the Master of the castle. 

Meg misses her, even-though their past relationship was somewhat strained by predator’s rivalry. She’s too small to return to the canals (as Meg would eat her instantly) so she’s kept in a cramped aquarium in the Master’s throne room.

Marble is the only one she seems to tolerate.


This dainty octopus has the well-earned scientific name of Wunderpus photogenicus! Each wunderpus has a unique white spot on its head that makes it possible for biologists to identify and study individual animals.
