Some sort of fish...

Danny, thanks for the fish practise!

You meant r2c78 as the last weak link, right?

Luke, r2c8 is of course also weakly-linked but r2c7 is sufficient to expose the swordfish as c7 but not c8 is in the cover set.

Peter, Congratulations on your solution. As it stands, I'd call it a Kraken Swordfish.

If you add [b1] to the base set and [r2] to the cover set, then you'd have:

Code:
 finned Franken Jellyfish c247b1\r2589 w/fin cells r3c1,r6c3

 |-----------+-----------+-----------|
 |  .  5  .  |  .  5  .  |  .  5  .  |
 | -5  5  .  | *5  .  .  | *5  .  5  |
 |  .  5 #5  |  .  5  .  |  .  5  5  |
 |-----------+-----------+-----------|
 |  .  5  .  |  .  5  .  |  .  5  5  |
