Acr-Hox2-5, Hox7 and Post2 expression in mid-trochophore larvae of Acanthochitona crinita. Anterior faces up. Left and middle column: stereomicrographs. Right column: light micrograph. a–c Acr-Hox2 is expressed postero-laterally, next to the stomodaeum, in two ventral, short and parallel longitudinal strands. d–f Transcripts of Acr-Hox3 are present in two distinct ventral parallel longitudinal strands. g–i Acr-Hox4 is expressed prominently in the hyposphere in two distinct domains which are antero-medially interconnected. j–l The expression pattern of Acr-Hox5 is present in two ventral longitudinal strands in the posterior region. m–o Acr-Hox7 transcripts are present in a ring-like arrangement in the posterior hyposphere. p–r The expression pattern of Acr-Post2 is present at the posterior pole of the larva.
