From: Unraveling the origin of Cladocera by identifying heterochrony in the developmental sequences of Branchiopoda

Figure 6

Ancestral developmental sequences ACCTRAN (upper row) and DELTRAN (lower row) developmental sequences for the crown - group nodes of Branchiopoda , Phyllopoda, Diplostraca, Onychocaudata and Cladoceromorpha. The developmental sequence obtained for Penilia avirostris (Cladocera) is additionally depicted for comparison. Red represents embryonic development and blue larval development. Green letters represent the hatching and molting processes. Note the last larval (metamorphosis) molt is transferred from 'AA' in the Onychocaudata to 'Y' in the Cladoceromorpha and to 'O' in the Cladocera.
