We recently received a question from a reader about whether or not it is possible to fish with hammerhead worms.

We’ll first provide some basic information about these creatures, and then we’ll move on to the more specific topic of fishing with hammerhead worms.

Hammerhead Worms in the Toilet

“This morning I discovered a worm swimming in my toilet.” So starts a reader’s email that we were sent a few days ago. (The reader originally contacted us through our All About Worms Twitter account.) The reader goes on to say he believes the worm in his toilet is a hammerhead worm, and indeed it looks exactly like a hammerhead worm, but he wasn’t particularly worried about identifying it. Rather, he was curious how the worm got in his toilet. He was wondering if it was possible that the worm navigated its way through his pipes to the toilet, perhaps coming up from the sewer. He also wondered if his “worst nightmare [had] been realized,” which is that the worm somehow came out of his body. So, the question before us is: how did a hammerhead worm end up in a toilet?

Long Brown Worms with Black Stripes – Hammerhead Worms

A reader wrote to us a while back about a long brown worm with black stripes that she found in a decaying stump. Fortunately, she sent us an excellent photo of the brown worm, which we were quickly able to identify as a hammerhead worm (sometimes understandably, but incorrectly, spelled “hammer head worm”). The reader was merely wondering what the long brown worm was, so we’ve technically already answered her question, but if we stopped writing now, we wouldn’t have a very satisfying article to read. So, below we supply some information about hammerhead worms, which includes the reader’s excellent picture.

Hammerhead Worms: Are They Harmful or Dangerous?

A reader from South Africa (Durban, South Africa, more precisely) wrote to us about two hammerhead worms that he found in his home. He was wondering if hammerhead worms are harmful or dangerous to animals or babies, and he was also keen to discover what is causing them to enter his home. So, the question before us is this: are hammerhead worms harmful to humans or animals (like pets), and how do you get rid of hammerhead worms? (Technically, the reader didn’t ask how to get rid of hammerhead worms, but he was wondering how they got into his house, and in answering the latter we also answer the former.)

Hammerhead Worms

A reader wrote to us recently about a hammerhead worm, or what is believed to be a hammerhead worm, that she found on her kitten. The worm was found on the side of the kitten, and before the reader could remove the hammerhead, the kitten licked it. The reader was concerned that this might hurt the kitten, and was wondering if the kitten would become sick from licking the hammerhead worm. Unfortunately, this question falls outside of our purview. We are not veterinarians, so all we can ever say is that if something is questionable about your pet, you should go to the vet’s office. We can, however, take this opportunity to talk a little about hammerhead worms, explaining what hammerhead worms are and what they do.

Types of Flat Worms

Flat worms are native to Indo-China, but they travel around the world by hitching a ride in greenhouse plants. For the most part, flat worms can survive just about anywhere, so no one region is 100 percent safe.
