Notes on the early stages of the commensal polynoid Acholoë Astericola (Delle Chiaje)
Little is known about the development of polynoids. A large number of unidentifiable polynoid trochophores and nectochaetes have been described by Nolte (1936) and others. As Thorson (1946) states, Nolte has done little to clear up the confusion that prevails in this group and his 'numerous fig...
