Reconstructing trait evolution is critically important for elucidating the processes generating biodiversity. However, this work in its infancy non-model clades which we lack a basic understanding of their ecology and biology. Here, compile information about prey preference, chemical acquisition colour pattern dorid nudibranchs (Nudibranchia: Doridoidei) reconstruct ancestral states using multi-gene phylogeny to investigate these key traits. Our analyses show that most recent common ancestor (MRCA) Doridoidei preferred sponge from they sequestered metabolites, subsequent shifts different types de novo synthesis defensive compounds occurred multiple times independently across phylogeny. Additionally, MRCA likely exhibited complex patterns, including spots or stripes, with uniform morphotypes evolving families. Despite fact many derive both metabolites pigments prey, found no evidence correlated amongst As part work, present representatives 88 genera 18 families, but there remain issues poor support tree. Nonetheless, first time, explore traits contributed diversification nudibranchs, highlighting need more refined data greater phylogenetic resolution future work.

Time calibrated phylogenies are typically reconstructed with fossil information but for soft-bodied marine invertebrates that lack hard parts, a record is lacking. In these cases, biogeographic calibrations or the rates of divergence related taxa often used. Although nudibranch have advanced input molecular data, no study has derived rate this diverse group invertebrates. Here, we use an updated closure date Isthmus Panama (2.8 Ma) to derive first chromodorid nudibranchs using multigene data from geminate pair broad phylogeographic sampling. Examining species
