Burdur toothcarp [SEP] parent taxon
Aphanius sureyanus
Aphanius sureyanus, the Burdur toothcarp or Sureyan killifish, is a species of freshwater fish in the family Cyprinodontidae.
The species is endemic to Lake Burdur in Turkey. It feeds mainly on an endemic copepod "Arctodiaptomus burduricus". The toothcarp is threatened by the water loss of Lake Burdur due to the feeds into the lake being dammed, excessive water being taken from the lake, and a reduction in rainfall due to climate change. An increase in salinity levels further impacts the species.
Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
