The species has « a period of pelagic development of over three months. […] A comparison between the duration of larval development and the velocity of the North and tropical Atlantic surface currents shows that transoceanic dispersal […] is possible even without a delay in settlement. » – R. S.

« All of the examined tonnoideans (except family Bursidae) have a pair of jaws in the buccal cavity. These structures constitute organic semicircular leaf-shaped plates with many rows of prismatic rods (Figure 2F). Jaws are species-specific in the shape of both plate and rods. Tonnidae have a curved claw on the outer edge of the jaw. » – Barkalova, Fedorov & Kantor: “Morphology of the anterior digestive system of tonnoideans (Gastropoda: Caenogastropoda) with an emphasis on the foregut glands”, Molluscan Research vol. 36(1), feb. 2016, p.5.
