Fasick et al. (Reference Fasick, Algrain, Serba and Robinson2019) recently reported their analysis on whale shark opsins and claimed, without any firm ground, that our previous study on the whale shark rhodopsin (the product of the RHO gene, sometimes also called an Rh1 gene) (Hara et al., Reference Hara, Y.2018) was not performed on the rhodopsin but on the peropsin (product of RRH gene). We have confirmed that we analyzed the product of the rhodopsin gene (Rhity0007829) that is phylogenetically categorized confidently in the clade of RHO (Supplementary Figure 8a of Hara et al., Reference Hara, Y.2018) as described explicitly in our previous publication.
