I noticed this scrawled filefish because it was catching the sunlight, as they sometimes do, and the blue scribbles on its side were beautifully illuminated.
The photo on the left is the first sighting I had of the fish, and as it dove I noticed something trailing it. This can just be seen below the tail. It looked like fishing line. So I followed it and got the top photo where I could clearly see that the fish was trying to dislodge a hook and line from its mouth. Not only that, but it had a good-sized slash in its side.
I had visions of trying to grab the line and remove the hook, but the fish kept going down, away from me and out of my reach. It disappeared from view and I was left only with the photos and the rather sad image of the struggling fish.
