I think the even more nuanced answer is that “fish” is not a scientific category so comparing it to mammals makes no sense.

Ichthyology ≠ Science
https://en.m.wikipedia.org/wiki/Fish
In a break from the long tradition of grouping all fish into a single class (‘‘Pisces’’), modern phylogenetics views fish as a paraphyletic group.
Paraphyly is a taxonomic term describing a grouping that consists of the grouping’s last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic with respect to the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and all of its descendants.
This is in contrast to the class
Mammaliawhich is a complete clade.In other words, I could make up a branch of science called
foobarthologythat studies Jurassic raptors, whales, and the Rock Dove, but that doesn’t mean those things are related, or a ‘true’ scientific group of their own. It just means I put them together for some other reason, either cause it’s easier for the requirements of the job, or I wanted to, or many other reasons including historical.“Scientific group” is not the applicable term. “natural group” or “monophyletic group” or “clade”, would be more… scientific
Sure, and not calling them fish is even more scientific. From a grouping perspective, (which is how you refer to it) there is no such group.
So, fish are paraphyletic to whales?

or something, I’m not a biologistContinuing a long proud tradition of “midwit” memes being made exclusively by people who think they’re the 145 IQ guy, but are actually the the 55 IQ guy who found a brown hood.
they’re a berry i think
Yes but only when culinary, this is why it’s okay for vegans to eat whale.
Broke: Whales are fish because they look like other fish
Woke: Whales aren’t fish because they’re in the class Mammalia, not Pisces
Bespoke: Whales are fish because any monophyletic group that encompasses all the fishes must also include the clade Tetrapoda
Artichoke: Whales aren’t fish because fishes are a paraphyletic group that includes the entire clade Vertebrata at the exclusion of the clade Tetrapoda.
Stick and Poke: Whales are fish because they’ve developed the same bodyplan and are in the same ecological niche as the pelagic fishes.
Look all I’m saying is Hank Green agrees with me that whales are fish.
Hank Green is great but good god the adhd runs strong in that one. Watch some of his vlogbrothers videos and count the number of cuts. It’s like watching Liam Neeson jump a fence.
Maybe that’s why I like him so much lol
all are fish i dont care
You can’t fool me. I’ve read Moby Dick and Melville dedicated an entire chapter about how whales are absolutely fish
I know a doctor of marine biology who disagrees with your assessment.
Everyone that doesn’t revel in their fishness is a coward or worse, a creationist.
I don’t know how anyone could read Moby Dick and not come away convinced of their obvious fishness. Surely one’s nature and behavior are more important than one’s reproductive organs.
Cladistically speaking, whales are just a big colony of eukaryotic clones.

Whales are mammals. How is the dude on the right even being pedantic and not just outright dumb?
There isn’t a simple evolutionary definition of “fish”, not the same way there is for, say, mammals. If you found the common ancestor of everything we call a mammal and said “everything descended from this one is also a mammal”, you’d be correct. If you did that for everything we call fish, every animal in the world would be a fish. Also, we decided which animals were fish mostly on vibes, so without a clear definition you can pedantically argue that everything is a fish including mammals.
That’s not quite true. A lot of worms, for example, wouldn’t be fish, but all fish would be worms. Most invertebrates also wouldn’t be fish.
Mammals are fish
Isn’t that only if they are born between February 19th and March 20th? 🤔
Those are fishies.
Generally not but some fish (Whaleshark) can be confused with a whale.
