So as many players are probably aware, many boss salmonids are just lesser salmonids with extra Octarian technology.
Smallfry
Fish Stick, Flyfish, Stingers
Chum
Scrapper, Drizzler, Steel Eel, Slammin' Lid, Mudmouth, Griller
Cohock
Steelhead, Big Shot, Cohozuna
Snatcher
Chinook (this could also be chum but I'm counting it here)
However, this leaves some salmonids out of this description:
Goldies seem to be their own unique breed, "1 in every 10,000 hatchlings are a Goldie"...which hatchlings though? I assume its the Chum.
Maws and Flipper Flopper both don't fit the bill of any lesser salmonid, but are the only salmonids able to submerge in ink. I don't think it would be a stretch to say that Horrorboros also falls into this family considering how it emerges from the water and maintains the eel-like body, and like the Flipper Flopper is able to stay in the air for long amounts of time.
Mothership is the only "salmonid" I can't put a definitive answer on, as we don't seem to have any info on who is piloting it.
Thoughts? Is there anything I'm missing?
