The funct ion of the shadow response has been examined in some detail in ascidian tadpole larvae (Woodbridge, 1924; Grave, 1944; Young and Chia, 1985; Svane and Young, 1989) where it appears to influence the settlement patterns of larvae, and in the hydrozoan medusa Polyorchis penicillatus where it is involved in vertical diurnal migration (Spencer and Arkett, 1984; Arkett, 1985).
