i don't care if they aren't fish i'm asking should they be fish

But whales *are* fish. Specifically secondarily aquatic sarcopterygian fish belonging to the mostly terrestrial clade called Mammalia.

Oh look! A post that gives both Moby Dick enthusiasts and evolutionary biologists a chance to trot out their fancy little facts

Anonymous asked:

Yoo i love your fish women art!!! have you drawn any whales yet? maybe smth like a whale shark could be a cool challenge!

gammelgaedda answered:

BOY HAVE I. I'm always drawing my orca Bonnie. But I'm guessing with whale (dolphins/orcas are toothed whales) you're thinking of Baleen whales right? which I've also drawn-- this is my Blue whale lady Botvi. She's from a scrapped setting I shared with someone once. Still want to throw her into the Rustpit setting somehow.... old uggo art incoming

and whale sharks are so pretty you are right I should draw one,,,,,

I still can't fucking get over how cetaceans adapted to spend their entire lives in the water and just never bothered to redevelop water-breathing. there's motherfuckers who spend an hour or more diving and the evolutionary solution is just "breathe a lot on the surface and then lower your heart rate to a near-hibernation level while actively cruising the seafloor for stuff to eat". totally insane solution to one of the oldest solved problems in biology

poondragoon

Well, there are some good reasons for that.

First, foremost, and Steve Alten be damned, one cannot simply "re-evolve" gills. All the bits and bobs that used to be gills in our water-breathing ancestors are jaw and ear bones now. If some kinda mammal wanted to reacquire the ability to breathe water, it'd have to be from scratch. Evolution is a cheap-ass, so as long as there's a perfectly good set of lungs on that fella, it's not gonna bother to make an entirely new lung-alternative.

Secondly - and psych, this is actually more important - compared to air, water fukken sucks as an oxygen carrier! At its highest, water's potential for holding dissolved oxygen maxes out at 14.6mg/L...for fresh water...at 0°C. Saltwater carries about 7-8mg/L of dissolved oxygen. Good ol' air, meanwhile, holds a whopping 21mg/L of oxygen! Compared to water, that's pure jet fuel! It's just more efficient to go up to the surface for a breath of air and hold it.

TL;DR, mammals don't have the tools to evolve the ability to breathe water and no incentive to do so in the first place.

its weird to me that dolphins and great white sharks have like, not totally dissimilar sizes and speeds when they're getting the oxygen for those muscles in a completely different way.

Drag, I guess.

Yeah: Sharks are just so smooth that, even with the more inefficient breathing method, they can still maintain similar speeds and sizes u_u u_u

I want to mention that this one channel recapping PICARD on YT does a up/down for most of the recap, but at the end, they do random Easter eggs/this-is-cool notes under the title "Cetacean Observations." Given that you were the one to think of that, I wanted to share that little homage they do.

dduane answered:

Thank you kindly... but that idea's not original with me at all! When it appears in my work, it's an homage to Rick Sternbach and Mike Okuda, who pushed for the cetaceans (and the Ops section they manage) to be included in the ST:TNG Technical Manual.

(Rick's an old friend of mine, and did some fabulous art of spacegoing dolphins, back in the day.)

...See this link for more info on Cetacean Ops' history.

top tweet: WHALES HAVE MEMES?

quoted tweet: Alder (A99) swims with a dead fish balanced on his head. Back in 1987, a K Pod orca started swimming everywhere with a dead salmon carefully balanced on the top of her head, and it soon became a popular Southern Resident fad as other orcas quickly started mimicking her behavior.

attached is a photo from above of an orca sticking its head above water, a fish laying atop its snout. /end ID]

The entire concept of cetaceans is pretty ridiculous. Dougal-Dixon ridiculous.

‘What if these little tiny ungulates went into the water and, wait for it, became fat torpedoes who scream to navigate.’

Definitive list of whales, ranked.

Right Whale: It has an upside-down head — a bold move that pays off.
Sperm Whale: Has a silly name but really excels in all areas of being a whale: staying underwater, fighting squid, spraying sonar around the sea, looking like an ocean bus. Having teeth rather than baleen means not having to eat krill.
Narwhal: Sea unicorn that has ocean sword fights. Slightly less cool when you realize its horn is actually a big tooth, making it the whale version of this.
Orca: Doesn’t look anything like the other whales and hangs out around the Pacific Northwest, so it’s basically the hipster whale. Eats real food like seals rather than krill. Was in Free Willy, but, then again, was in Free Willy. Kind of an asshole, but you can’t argue with success. Secret shame: actually a dolphin.
Humpback Whale: Basic canonical whale. Has good press. Bit too mainstream, really.
Beluga Whale: Ongoing experiment in whether white privilege applies to cetaceans.
Blue Whale: Coasting on its size; must try harder.
Gray Whale: Blue whale that’s smaller and more boring.
Minke Whale: Kinda puny for a whale.
Fin Whale: Second biggest animal in the world, i.e. the first loser. Described by Roy Chapman Andrews as the “greyhound of the sea,” and we all know what Captain Hank Murphy of Sealab said about greyhounds. (”Too pointy.”)
Beaked whale: You are not a bird, please reconsider your choices.
Pilot Whale: Dolphin with ideas above its station.

I may disagree with some of the particulars of these results but I can’t fault the methodology
