Although barnacles are commonly found Tucuxis, they are not considered parasitic, as they have no known negative impact on their host. Limited information exists regarding parasites of Tucuxis; however, stomach flukes and two species of nematode (Anisakis typica and Halocercus brasiliensis) are known to infect the gastrointestinal tissues of this species at various stages throughout their complex life cycle.

Commensal/Parasitic Species:

• stomach flukes, (Braunina cordiformis)
• parasitic nematode, (Anisakis typica)
• parasitic nematode, (Halocercus brasiliensis)
• barnacles, (Xenobalanus globicipitis)
