Peptide corresponding to the calculated mass of the T. stephensoni venom SA8 peptide is abundant in acontia, gastrodermis and epidermis. A Haematoxylin and eosin stain of T. stephensoni section. B Putative peptide observed at 5409 m/z with the highest abundance in internal structures adjacent to the mesenterial filaments (m) and pedal disc (pd), which corresponds to the location of acontial filaments
