| | Hesionidae |
 | | Grube (1850) chose to base the family group name on Hesione, after the princess of Troy who was rescued by Hercules. |
 | | Accordingly, all juveniles hitherto studied (members of Gyptis, Hesiospina, Micropodarke, Nereimyra, Ophiodromus, Podarkeopsis, and Psamathe; unpublished observations, but see also Haaland and Schram, 1982, 1983; Schram and Haaland, 1984) have a median antenna, situated medio-dorsally on the prostomium. |
 | | In some taxa the median antenna remains dorsal during ontogeny, in some it migrates forward to the anterior margin of the prostomium (see Ophiodromus title illustration), and in others it becomes reduced (Figure 6 left). |
