A Genomic arrangement and orientation of SA8 genes in T. stephensoni and A. tenebrosa. The inverted SA8 gene identified in the genome of T. stephensoni is depicted in blue. The first collinear block is depicted in orange while the second collinear block is shown in purple. Numbers in square brackets indicate the scaffold number for A. tenebrosa SA8 genes. B Sequence space of the SA8 family using 102 SA8 sequences from 14 actiniarian species spanning three superfamilies. Sequence space analysis of mature SA8 peptides reveals that they fall into four clusters (yellow, black, pink, red), with the T. stephensoni venom SA8 peptide found in the largest cluster (indicated by blue arrow)
