The two filaments on the side opposite the siphonoglyph (the narrow, flagellated groove of the pharynx) are the longest and thickest, and are often bilobed; the filaments on the other six mesenteries contain digestive gland cells, and produce gonads (Fabricius and Alderslade, 2001).
Other three species of this genus have been inferred to reproduce asexually based upon their aggregation habit and the irregularity of some characters like number of mesenteries and siphonoglyphs.
