Very interesting article on polypteridae evolution (warning hard read)

  • We are currently upgrading MFK. thanks! -neo
yeah same, unless I find longfin albino those are pretty cool haha. I wish longfinned varieties of ornates or of palmas polli were common haha

i googled the lake turkana senegalus (that link kept on sending me back to the mfk homepage haha) very impressive, they do have a complete different over look, and it seems they get quite a bit larger then regular ones, wow i would love to have one, how much are they price-wise when theyre around?

isnt it the same thing with teugelsi? they only find them in a certain river or lake? im not sure if thats correct

The price is defiantly not pretty. It's harder to get than the lake Turkana PBBs which are insanely pricy (but worth it). The lake Turkana region is very dangerous so getting these right now is kinda out of question.
 
THIS IS MY JAM. Thanks for passing it along!

I wonder what the original lower jaw bichir was, they found very little variation between congicus and endlcheri, suggesting they are extremely closely related and that other lowers all evolved from the same ancestral pair

Correct me if I'm wrong, but I believe they said that P. e. congicus and P. e. endlicheri should be separate species, and are not as closely related as we previously thought. Same with the P. palmas complex. Or maybe I'm just misinterpreting what you said...

I think what he meant were they're very genetically close. Of course there are obvious physical traits that tell you they are different, but as we most know there isn't a lot (or at least as much as we want) info on polypterus genetics (there is some really detailed good stuff out there, but IMO as time passes more and more will turn up).
 
I think they were saying the opposite. They were always thought to be close (as in subspecies) because of their physical traits, but with this genetic evidence..."Taxonomic changes are clearly needed and we recognize P. e. congicus and P. e. endlicheri as distinct species, P. congicus and P. endlicheri". They found a similar situation with P. palmas.

When they say "Polypterus endlicheri is paraphyletic with respect to both P. bichir and P. ansorgii", that means that one of them is more related to P. bichir and the other is more related to P. ansorgii (as demonstrated in the second cladogram). However, I'm definitely hesitant to believe one study 100%. Especially since they only had ~2 specimens of each species.
 
yeah see what i think would make a good study is getting 5 or so of the species collected at different points like P.e. farana and P.e. tikitso and seeing if the only difference is pattern and looks or if genetics is also affected as well

If anyone has pictures of these Turkana senegals, I would like very much to see them. I haven't been able to find any myself, for some reason.
