Acr-Hox2-5, Hox7 and Post2 expression in late trochophore larvae of Acanthochitona crinita. Anterior faces up. Left and middle column: stereomicrographs. Right column: light micrograph. af Acr-Hox2 and Acr-Hox3 are indistinctly expressed along the antero-posterior larval body axis. gi Acr-Hox4 transcripts are ventrally present, posterior to the stomodaeum and around the lateral edges of the ventral foot. jl Two faint Acr-Hox5 strands are expressed in the mid-region of the hyposphere. mo Acr-Hox7 transcripts are indistinctly present in two postero-lateral expression strands. pr Acr-Post2 expressionis present in the posterior pole of the hyposphere. Scale: 50 μm. ao apical organ, ds dorsal shell plates, f foot, pt prototroch
