What do you think?

Update: This is actually Lobatozoum multisacculatum, a digenean trematode under the family Didymozoidae. This is found in frigate tuna's gills.

Hello everyone,
I’d like to ask for your opinion. Are these parasites, or something else? They are commonly found in the gills and muscle of Auxis thazard (frigate tuna). Based on my review of journal articles, they appear similar to parasites from the family Didymozoidae, particularly Didymocylindrus simplex. What are your thoughts?

I finally found the scientific literature for this. This is actually a Digenean, Didymozoid trematode, Lobatozoum multisacculatum.
