For preserving the least toxic and most culturally relevant Tumblr heritage posts.

Image descriptions and plain text captions of written content are expected of all screenshots. Here are some image text extractors (I looked these up quick and will gladly take FOSS recommendations):

-web

-iOS

-android

Please begin copied raw text posts (lacking a screenshot that makes it apparent it is from Tumblr) with:

Yes, fish would be a morphology that includes gills, fins, streamlined body shape for swimming, etc. But there is no good phylogenetic definition because all the animals we call "fish" do not form a monophyletic group. The monophyletic group encompassing all fish would include also mammals, reptiles including birds, and amphibians because these all have fish ancestors

The challenge was to come up with a group "which includes both trout and sharks but not humans". It seems like "gills" satisfies that pretty well.

Animals with gills do not form a monophyletic group.
