Bioinformatic prediction of arthropod/nematode-like peptides in non-arthropod, non-nematode members of the Ecdysozoa

► Bioinformatics reveals that several arthropod/nematode peptide families are conserved in other Ecdysozoan phyla. ► The predicted peptides are highly similar to their arthropod and/or nematode counterparts. ► The identified transcripts and predicted peptides provide a foundation for future evolutionary and physiological studies in the “minor” ecdysozoan phyla.
