Some eliminate others, if you act on them before you finish looking. Even worse, there is a w-wing that can eliminate all of them!

The strong link in c2 forces one of the 35s in r2c4 or r6c5 to be 5. That has some eliminations that solve it all.

Sudoku Cue and JSudoku don't agree on whether some patterns are finned swordfish or sashimi swordfish. To make it a tad worse sashimi patterns can have a fin. <sigh> I will call sashimi/finned swords "sword+" when I am not certain, or when I am lazy.
