Table 2 Neuropeptide families identified in six species of Actiniaria: Anthopleura elegantissima, Anemonia viridis, Nematostella vectensis, Phymanthus crucifer, Scolanthus callimorphus, and Exaiptasia diaphana. Only those neuropeptides that have multiple identical or similar copies on their preprohormones are listed here and from them only those with the highest copy numbers are given. The isolated and sequenced neuropeptides from A. elegantissima are abbreviated: A-RFamide (=Antho-RFamide); MMA (= Metamorphosin A); RP-1, -2, -3, -4 (= Antho-RPamide-1, -2, -3, -4). If more than one gene codes for the peptides, this is highlighted in blue in the last row in parentheses. The amino acid sequences of the preprohormones are shown in Additional files 1 to Additional files 5
