Gene families related to vision in marine sedentarians (spionids and siboglinids). A The anterior end of L. polybranchiata, dorsal view. ca, caruncle; pa, palp. B Diagram showing key transcription factors in eye development. Red crosses indicate gene loss in L. polybranchiata, disrupting Mitf and Otx pathways (dashed lines), essential for pigment cell specification. These interruptions may explain the lack of eyes. C The number of genes encoding eye transcription factors. D The number of genes involved in the vision and biological rhythm
