Last year a paper came out suggesting that bowfin be split into 2 different species. Roughfish.com has accepted these findings and from here on out bowfin are now divided into Eyetail Bowfin and Ruddy Bowfin. Eyetail Bowfin are found in the Mississippi and Great Lakes drainage basins, as well as the east coast north of Chesapeake Bay and can be differentiated by the spot on the tail and that the males change color during the spawning season. Ruddy Bowfin are found in coastal drainages east of the Mississippi River and south of Chesapeake Bay and do not have an eye-like spot on the tail nor do they change color during the spawn. In order to submit both species for a contest the Eyetail Bowfin must have the eye-like spot which is lost on older females.
Because the user base of this website is mostly within the range of the Eyetail Bowfin, that is being treated as the default bowfin that previous entries are treated as. This does go against what would be expected given the scientific names of the 2 species, however this way the majority of lifelist entries will stay accurate without having to be changed. Though if a bowfin is from Mississippi, Alabama, Florida, Georgia, South Carolina or North Carolina it is most likely a Ruddy Bowfin, unless it is from the Mississippi River drainage.
Enjoy your armchair lifer if you have caught both or target if you haven't!
I was waiting for this update!
Is there still talks that there's even more species, but this is the first segregation?
I've heard of possible further splits though I haven't found anything published on the matter
2017: Total species (44), New (12)
2018: Total species (94), New (50)
2019: Total species (115), New (48)
2020: Total species (63), New (9)
2021: Total species (72), New (11)
2022: Total species (150), New (58)
2023: Total species (131), New (46)
25% of the bowfin I caught down in the everglades had the spot.
Ruddy bowfin have an eye spot, it is generally just less well defined. Would be tough to ID a washed eyetail versus a normal Ruddy without dissection
The ruddy I've observed have not had any spot though I have seen pictures of ruddy with a spot on inaturalist. I believe the spot ruling was just so the judges would have something to look at even though it is really more on the honor system that someone caught a bowfin from both of their ranges

Great topic, looking forward to having this more clear, any other traits for the ruddy? I've only caught 1 bowfin in Florida and it did have a spot so I'm not sure what species.
"There's always a bigger fish"
The tooth counts are different but really the best way to tell them apart is range and any bowfin caught in Florida is going to be ruddy

Yeah for a lifelist standpoint just stick with range. The two species don't overlap

If more species get described/redescribed, that might change things but there is a pretty good chance they won't overlap in range either.
