Figure 4From: How Hox genes can shed light on the place of echinoderms among the deuterostomesComparison of Hox expression domains in crinoids and echinoids. Figure showing antero-posterior organization of anatomical elements at postmetamorphic stages. Hox gene assignments in square brackets represent complementary data from other taxa. Vertical purple arrows represent the somatocoelar hox vectors.Back to article page
