The frigate tuna, frigate mackerel or alagaduwa (Auxis thazard)[citation needed] is a species of tuna, in the family Scombridae, found around the world in tropical oceans.
The eastern Pacific population is now regarded as a separate species by some authorities, Auxis brachydorax.
[3] As most fishes, the frigate tuna harbours a number of parasites.
Among these are a series of digeneans, which are parasititic within the intestine.
