POV: You’re in the middle of the ocean and, for some reason, you need to write something down. To your surprise and delight, you discover that there are about three hundred species of sea pen! Unfortunately for you, none of them can be used for writing.

Named for their resemblance to old-fashioned quills, sea pens are actually not single animals: They are colonies of polyps. All of the polyps work together and each has a role to play. There are feeding polyps that catch plankton, as well as polyps that circulate water to keep the colony balanced and upright.

Today is Wet Beast Wednesday!

Today’s wet beast is: Sea Pen

Olive’s wet beast fact: contrary to its misleading name, this colony of polyps can not, in fact, write anything. Illiterate liar.

Stay tuned for more Wet Beast Wednesdays!

Some details from a mural I did along the side of my bed. Going for the vibe of those old science museum pieces where they scroll through all the different eras of earth history...

At 2994 meters on a never-before-surveyed seamount north of Johnston Atoll, the team made a thrilling discovery — the chance to examine an animal spotted for the very first time in the Pacific Ocean! The sea pen, a colonial cnidarian, had a single large feeding polyp with pinnate (barbed) tentacles stretching over 40 cm from its 2-meter-long stalk.

Solumbellula monocephalus is the only described species in the genus and until this sighting was only known to live in the North and South Atlantic and Indian Oceans. Before this discovery of the colony, the animal had never been seen in the Pacific Ocean. Further review of the footage and this sample will help experts determine if this is the first Pacific S.monocephalus or potentially a new species in this ocean basin.

Enjoy some beautiful close-ups of this coral relative that astounded our team with a detailed view of its stinging feeding tentacles that capture marine snow and food particles drifting by its home on an underwater mountain sedimented saddle. Two individuals were spotted on this dive, confirming a population within the protection of the Johnston Unit of Pacific Remote Islands Marine National Monument. This huge range expansion of Solumbellula in the Pacific Ocean reminds us how important ocean exploration efforts are to understanding this diversity of our planet!

a bit late bc time zones, can i still get a trick or treat about corals?

Yes! Please just hurry and grab some of the sea pens (which are a type of octocoral) down at the bottom before this Tritonia sea slug gets them (sea pens are also their favorite treat)!

Video ID: Fifish ROV footage with labels showing it is a dive on July 8th 2023 at a depth of about 47 feet. There are several tall orange sea pens poking out of the sandy bottom and some long fish. We zoom around to look at a few different ones. Up close to them you can see there's a bit of a bulbous buried part that looks kind of like a carrot and then a big billowy feathery part sticking out thats made up of little tiny zooids.

Anthozoa is a class under Cnidaria which includes marine invertebrates like sea anemones, sea pens, stony coral, and soft corals, it has 10 orders and thousands of species!! Anthozoans completely lack a medusa stage they are only ever polyps throughout their life. They’re one of the most popular Cnidarians due to some being important reef building coral species. There is many subclasses and orders under Anthozoa.

"See you tomorrow"

MDZS Disco Elysium AU part 4 [prev parts]

#better drawn mdzs #MDZS Disco Elysium AU #mdzs au #Lan wangji #wei wuxian #yiling laozu #Happy Belated Halloween!#digital art #Thank you all for your patience as I drove myself into a madness only known by those lost at seas alone.#I put a lot of time into this one! It's not perfect but I am very happy with it + I am so happy to put down the tablet pen.#Digital art has some nice features but I'm sticking with traditional! I need a month to recover from the 2+ weeks of torture.#Okay lets talk about the AU and the comic now #Disco elysium has some of the best existential-horror-dream sequences I have ever seen.#The dialogue here is heavily inspired by The Final Dream - A scene I'd love to talk about more were it not so heavy with spoilers.#My AU is a lot more complex than a simple character swap but I really felt like LWJ + YLLZ fit this scene.#The final dream is about being unable to move on from a lost love. From something You made holy. From something You ruined.#It is about realizing that no matter how smart you are or what you offer or how you try to change -#You will never be able to turn back time. You will never ever be able to fix what is broken. That you also have been broken for a long time #You are a fuck-up who worships the nail covered ground of someone who did not want to be holy. And even though it hurts-#You cannot let this nightmare go. The pain keeps the love close. It is worse to forget. You promised to remember.#WWX died thinking LWJ disliked him. LWJ lost someone he thought was revolted by his love.

love letter to alterna

words adapted from Stephen Dunn’s Love Poem Near the End Of the World

This was made for class, we had to make a comic that had no panel borders. the layout is strange because this is how it looks like when it’s read (not the best picture;;):

The back of it also has a link to a playlist. It has some songs that remind me of the atmosphere of alterna. They’re a little strange and ambient, just like the soundscapes there!
