Indo-Pacific humpback dolphins eat a variety of fish and are prey to some sharks. They also host some parasites, such as nematodes (Anisakis alexandri), which affect the stomach. In Hong Kong, lungworms (Halocercus pingi) have been observed in their orbits. Barnacles (Halocercus pingi) have also been observed living on the skin of Indo-Pacific humpback dolphins.
