Fig. 2From: Metamorphic remodeling of morphology and the body cavity in Phoronopsis harmeri (Lophotrochozoa, Phoronida): the evolution of the phoronid body plan and life cycleA scheme of consecutive stages of metamorphosis of Phoronopsis harmeri. In all panels, the dorsal side is to the top, the ventral side is to the down. a Competent larva. b Start of eversion of the metasomal sac. c The metasomal sac is completely everted. d Stage of eating of the preoral lobe and the postoral ciliated band. e 4-h-old juvenile with completely formed blood system.
