Heterochronic changes and ancestral developmental sequences within Decapoda. Phylogeny of Malacostraca as in Figure 11, but showing only Decapoda. Ancestral ontogenetic sequences reconstructed by heterochrony analysis using PGi are shown for the decapod and the pleocyemate LCA, as well as the terminal sequence of S. ingentis (Dendrobranchiata).
