hynacs are expressed at the base of the tentacles or at the peduncle. Whole mount in situ hybridizations revealed a diverse expression of different HyNaCs. hynac2 to hynac6 and hynac11 are expressed at the base of the tentacles, while hynac7 and hynac10 are expressed at the peduncle. hynac8 and hynac9 are expressed ubiquitously along the whole body column. Note that hynac2 is faintly expressed over the whole body column including the peduncle. Expression of hynac12 could not be detected by in situ hybridization.
