“…Flatfishes (Pleuronectiformes) are a very diverse order placed within a phenotypically varied assemblage of percomorph fishes known as Clade L, Carangimorpha or Carangimorpharia (Betancur‐R., Broughton, et al, ; Campbell, Chen, & López, ; Chen, Bonillo, & Lecointre, ; Dettaï & Lecointre, ; Li et al, ; Near et al, ).
