I once caught a Coddle Fish trolling off of Sekiu. It fought in a very similiar manner. We didn't have any idea what it was. Very strange creature. It hardly fought at all. When we fist saw it, we thought Halibut! but no. We got it up to the boat and it started to climb out of the water up the line with those weird tentacle like things. It then freaked out and screamed off about 40 yards of line and just sat there. We motored up to it and cut the leader to get the flasher back.

That was weird.

Here is a picture of one ... cuttle fish
