How about rating a sturgeon on your scale? Really fun idea by the way! :)

Thank you very much :D

Today on CHUNK, FUNK, GUNK! We rate

the STURGEON:

5/10 Chunk

9/10 Funk

0/10 Gunk

I have to start by saying that I don’t really know much about Sturgeon. They’re incredibly unique and recognizable fish, so they get a high funk rating. Doesn’t look very pleasant to hug, so low chunk. Do not seem to secrete slime or mucous, no gunk.

After some quick research, I have learned substantially more and uphold my previous ratings. I also wish to mention that sturgeon have existed for thousands of years and are now bordering on extinction due to human interference.

(Edit: 4/10/23 - Changed chunk from 2 to 5/10 after revising my standard)

Daily fish fact #428

It’s my friend’s birthday! She requested an…

Atlantic sturgeon!

It used to inhabit many more areas in the Baltic Sea, but building dams caused it to go extinct in the area in the early 20th century. The Atlantic sturgeon has also declined in North America, but it is being reintroduced into its old habitats!

Hello! May I request a sturgeon, specifically the species Acipenser oxyrinchus?

Day 21 of Fishuary, nearly caught back up!

Prompt: Atlantic Ocean

—

Look, if I have an excuse to draw a sturgeon… I’m gonna draw a sturgeon, okay?? I can’t help it! It’s literally half of my online handle.

Acipenser oxyrinchus oxyrinchus has a long ass name. Good for her.

What about sturgeon haven’t I said before? I feel like I gotta use my facts a bit sparingly haha,, sturgeon are cool, and Atlantic sturgeon are super pretty. Beautiful tan colours, love it.

Bit of a photo dump of Margaret, who got installed along with 24 other gorgeous Sturgeons in downtown Augusta, Maine last Saturday.  I know a lot of folks that follow me here are anything but local, but they will be up for 2 years so if you ever happen by, many feesh await.

This is a sturgeon appreciation post.

I love those little guys.

Beluga, Atlantic, Lake, Gulf, you name it.

I am appreciating them all right now

Time to get your sturge ON!

I made some plushie Atlantic Sturgeons in response to the results of a recent poll, where sturgeons came out on top!!! You can get yourself a plushie sturgeon over here: https://www.palaeoplushies.com/shop/sturgeon

I ship worldwide!!

I'm very tired.

Today I want to talk about the Pacific Northwest Tree Octopus (Octopus paxarbolis).

OK, so for those who don't know, the PNW Tree Octopus was an internet hoax created in 1998 consisting of a website detailing the animal's life history and conservation efforts. It's completely fake - saying that up front. This animal never existed.

But if you look at this from a speculative biology standpoint? It's genius.

There is one, and only one, thing preventing Octopus from colonizing and being hugely successful in terrestrial environments in the PNW, and that's the fact that no cephalopod has ever been able to overcome the osmotic stress of inhabiting freshwater. We don't know why this is; other mollusks evolved freshwater forms just fine. But if you hand-wave away that one, single limiting factor, the PNW is just primed for a terrestrial octopus invasion.

The Pacific coast of North America is an active tectonic boundary, meaning the coast transitions pretty much immediately into the Cascade and Coastal mountain ranges (contrast with the east coast and its broad Atlantic plain). It's also a lush temperate rainforest, with very high precipitation. This means lots and lots of high-gradient mountain streams with lots of waterfalls and rapids and cold, highly oxygenated water, and not as many large, meandering rivers.

This has important consequences on the freshwater fauna. For one, there are not many freshwater fish in the Pacific Northwest - the rapids and waterfalls are extremely hard to traverse, so many mountain streams are fish-free. There also just isn't much fish diversity in the first place - there's sturgeon in the big rivers, salmonids, a few sculpin and cyprinids and... that's pretty much it. These cold northern rivers are positively impoverished compared to the thriving fish communities of the Mississippi or Rio Grande.

Few fish means few predators, and depending on the size of the first freshwater octopus, salmon and trout just wouldn't be much of a threat. And while these rivers don't have much in the way of fish diversity, there's lots of prey available - crayfish, leeches, mosquito larvae, frogs and tadpoles, water striders, and other aquatic insects, just to name a few. So the first Octopus pioneers to invade the rivers would be entering what essentially amounts to a predator-free environment with lots and lots of food and no competition. Great for colonization.

These ideal conditions get even better once you get up past the rapids and waterfalls, since there's no fish whatsoever in those streams. Octopus, with their sucker-lined arms, are perfectly equipped to navigate fast-moving, rocky-bedded streams and climb up cliffs. They'd also be well able to traverse short stretches of dry ground to access even more isolated pools and ponds. In fact, once Octopus overcome the osmoregulation problem there's nothing at all preventing them from colonizing land in earnest, since the PNW rainforests are so wet; there's no danger of drying out.

Finally there's the question of reproduction. Octopus are famously attentive mothers, because they need to keep the water around their eggs moving and well-oxygenated. In a mountain stream, this wouldn't be an issue, because the cold, turbulent water holds lots and lots of oxygen. Breeding in high mountain streams would be ideal, and the mothers might not even need to attend to their eggs, freeing them up to evolve away from semelparity and allowing them to reproduce more than once in their lives; their populations would thus increase rapidly and dramatically.

I think, if octopus managed to invade freshwater ecosystems in the PNW, it would dramatically change the ecology much like an invasive species. They'd be unstoppable predators of frogs, bugs, slugs, maybe even larger animals like snakes, birds, and small mammals. Nothing would eat them except maybe herons, and things like bears and raccoons would give them a wide berth due to their venom. They would rule that landscape.

The tl;dr is that the PNW is primed for invasion by cephalopods, if only they could manage to overcome the osmoregulation problem and live in freshwater. If the Pacific Northwest Tree Octopus really did exist, it wouldn't be a shy and reclusive species on the brink of extinction; it would be a pest, an invasive, overpopulated menace you couldn't get rid of if you wanted to. I can just imagine them crawling up onto people's bird feeders and either stealing the nuts or luring in unsuspecting sparrows and starlings. They would sit in the trees and throw pinecones at hikers for fun. They would be some unholy mixture of snake and slug with the personality of a magpie and I am incensed that they only exist in fiction.

Kind of a broad question, but what's your favorite fish? (If already answered ignore this ig)

I have gotten this question before but I love answering it! My favourite fish species is the Atlantic sturgeon, Acipenser oxyrinchus! I love sturgeons overall, I love their long snouts and their barbels and their scales and their body shape and the way their gills move because it makes them look so ancient and powerful. I find it super cool how big they grow but they're still bottom feeders, they're gentle giants! The Atlantic sturgeon has a slight edge over the other sturgeons because it used to be native in Finland, my home country. It has gone extinct now, (not extinct everywhere thank goodness...), but it wasn't even that long ago that the last sturgeons swam in these waters, in the 1930's! Something about the thought of these powerful, large, ancient animals migrating inland through rivers, the very rivers I've seen and swam in, slowly waving their muscular tail from side to side, traveling kilometer after kilometer through the deep, persevering hardships to go continue their family line is... wow. I wish I could see them in the wild. Magnificent and magical animals is what they are.

#i also like the northern pike! its one of my long-time favourite fishes but currently “only” my second favourite #sturgeon #sturgeon fish #atlantic sturgeon #asks #anonymous #anonymous asks #anon

Uncharismatic Fact of the Day

The sturgeon's name is quite appropriate; it loosely translates to 'stirrer'. These species have poor eyesight, and instead find food by feeling through the mud with their sensitive snouts and whisker-like barbels.
