Figure 4 in Evolution of spermatophore transfer mechanisms in cephalopods

Figure 4. Spermatophore-related characters parsimonious optimization using different hypothesis for the internal relationships of Decapodiformes. Character states are traced and indicated by shape and colour codes; coloured branches (and coloured boxes to the left of taxon names) refer to the spermatophore attachment type, and coloured symbols to the remaining characters. Presence of more than one colour in branches or rectangles, and the presence of a question mark both indicate equivocal character states. (A) Tree according to the maximum likelihood analysis of Lindgren (2008); (B) tree according to the Bayesian analysis of Lindgren (2010).
