Fig. 3From: Hox gene expression during development of the phoronid Phoronopsis harmeriDevelopment of Phoronopsis harmeri. Blastula, 12 hpf (A, A’); gastrula, 24 hpf (B, B’); early larva, 42 hpf (C, C’); pre-tentacle larva, 56 hpf (D, D’); actinotrochae: 3 dpf (E, E’), 5 dpf (F, F’) and 7 dpf (G, G’). For each developmental stage the left panel shows embryo or larvae in dorso-ventral view and right panel (marked as’) in lateral view with ventral to the left; anterior is to the top on all panels.
