Mutant Fish
When fish are no longer restricted to rows and columns, strange varieties emerge. When either the defining set or the secondary set contains a mixture of rows, columns and/or boxes, these fish are classified as mutant fish.
There are no mutant X-Wings, because the interaction between a single box and line is fully covered by the Locked Candidates technique.
Here is a fish diagram of a Mutant Swordfish, with the defining set consisting of 2 rows and 1 column, and the secondary set containing 1 column and 2 boxes.
Mutant fish can also be found in finned variations.
