Summary of differential opsin expression data from the four different A. planci tissue samples. Counts were normalized for transcripts length and library size using transcripts per kilobase million (TPM) in order to compare opsins for each tissue type. For eyes (red) the highest expressed opsins are r-opsin, peropsin, chaopsin, RGR opsin, and go-opsin, with c-opsin 1.2, c-opsin 1.3, and neuropsin being expressed at low amounts, while no expression is observed in c-opsin 1.1b. RGR opsin and peropsin were the highest expressed amongst the other tissues. The mixed tissue (green) and tube feet (purple) have little to no expression (TPM < 0.5) of c-opsin 1.2, c-opsin 1.3, go-opsin, and chaopsin
