Each color represents a different module where green is the three-linkage module and blue is the remainder of the bones (neurocranium, nasals, pharyngeal jaws, and premaxilla). In the CR test results, wrasses, cheilines, scarines, and julidines are being represented by hypothesis 3 while hypsigenyines represent hypothesis 10. In the distance matrix test, wrasses, julidines, and hypsigenyines represent hypothesis 2, cheilines represent hypothesis 8, and scarines represent hypothesis 1. All these hypotheses were best supported in the corresponding tests.
