Swim away immediately. That wriggling worm is a deadly trap attached to a hidden metal hook.

If you bite it, you risk getting caught and pulled out of the water.

To stay safe and satisfied, follow these guidelines:

- Inspect carefully: Do not touch anything that isn't floating freely or resting on the bottom without a string attached.

- Spot the signs: The thin "line" is actually fishing line and indicates a trap.

- Look for alternatives: Stick to natural, unattached food sources like free-floating larvae, insects, or smaller fish.
