Ragworms may be an ugly looking bug but they make great fishing bait and are often sold along the Atlantic coastline to avid fishermen.
For those who are used to fishing with little fish worms, ragworms are a completely different story. They can get pretty big and need to be handled carefully so that you don't get nipped. You need to make sure you pierce them right behind their head with your hook so they aren't as likely to take a bite out of you. They can even hang on if they get a good grip on you.
Beware of the greenish colored ragworms as they have the nastiest bite and you'll regret touching it for a long while to come.
