Well I do regonize some similar breeding behaviour between T c bauri and T c major
But I do not regonize T c major is more agrassive compeard with T c triunguis its more depending on the individuel animal I think.
Same with beeing more aquatic I don't see a difference in captive they all like whater very much
Think intergrades between T cm and T ct occurs but is one of the most difficult intergrade to regonize.
Spliting the carolina group is a bit drastic on these points and willl not happen.
I believe in the nomenclatuur followed Colllins (1997) and only thinks its maybe possible there is no difference in T n nelsoni and T n klauberi, (one specie) but that is another difficult subject
