Arius venosus (n= 28) ( Fig. 5 , Supplementary data 5)

The appearance of the otoliths is very similar to that of A. oetik and there are no obvious distinguishable features between the two species others than some of the A. venosus otoliths (n= 3) have deep bent ILb, while the others (n= 25) have shallow ILb.
