In the tree of life, flounders are a sub-sub-...-sub-species of bilaterally symmetrical animals: https://www.onezoom.org/life/@Holozoa=5246131?otthome=%40_ozid%3D1&highlight=path%3A%40Apionichthys_finis%3D3640785&highlight=path%3A%40Bilateria%3D117569#x2913,y-2310,w8.2796

Edit: let me preemptively be a pedant to myself and say that "sub-...-species" is wrong because "bilaterally symmetrical animals" is not a species. Flounder is itself a species AFAIK, not a sub-species of anything. It is a descendant of the common ancestor of all bilaterally symmetrical animals. There, now surely no one will find anything to be pedantic about :D

I appreciate that information. However, flounders themselves are not bilaterally symmetrical. I have caught many dozens of them and it's pretty easy to tell that they are not.

[-] austinfloyd@ttrpg.network 7 points 1 day ago

Flounders are born symmetrical; eye migration happens as they transition to the juvenile stage of growth.

[-] BreadOven@lemmy.world 2 points 1 day ago

Isn't it referring to during development? Like as they're forming, they are bilateral? I haven't taken developmental biology in many years, so I'm maybe wrong.

[-] Crashumbc@lemmy.world 2 points 1 day ago

They are born (or hatch too lazy to look up) and their eyes move later once they get larger.

[-] BreadOven@lemmy.world 1 points 26 minutes ago

Yeah. I just wasn't sure at what point things are considered to be bilateral or otherwise.

I thought it may have been during the development process, but can't remember.

Just like starfish!

Forego the illusion of species and families. It's taxa all the way down.
