It seems to us that almost every summer, the flatworm becomes the target of news stations who want to spread mass hysteria and inject fear into the hearts of those who might not know any better than to trust the words of journalists twisting the words of experts. We’re here to set the record straight and clear the name of flatworms. This year, hammerheads are being targeted. They have been targeted in the past, but so has the New Guinea flatworm. In this article we will be responding to a “ CBS article on hammerheads” published by Li Cohen.

“This worm was crawling up my shower window”, writes PG in her submission regarding the beige-colored, worm-like critter pictured below. “I think it resembles the invasive hammerhead flatworm but does not have the crescent moon-shaped head. Do you know what type of worm it was? I’m located in southeast Texas.” From the photo, we cannot determine a specific identification, though we agree with PG that it could be a flatworm, as there are species of flatworms with this coloration. We do not agree that it is a hammerhead, for the very reason that PG gives: it does not have the eponymous hammerhead.

“I keep finding what looks to be small worms,” writes this reader in her submission regarding an array of creatures. “But, while walking through my apartment after a VERY thorough cleaning, I felt like I had stepped on a piece of glass. I couldn’t find anything until I swept the area (after already mopping it three times), and what I saw in my dustpan threw me into a major panic attack. I used my Google Lens to see if I could figure out what I was looking at. Every article I could find said it was hammerhead flatworms that I was looking at. The apartments I live in have had a BAD infestation with bed bugs, and I have recently been cleaning up dead bugs and black spots that keep appearing everywhere around my apartment. I have not seen a live one, although I have woken up with bites.”

“I found two black flatworms”, states this reader about the creature pictured below, which indeed has a glossy black body, with a light gray/white underside. “I already am infested with the hammerhead worms, now what is this worm?”

“My grandson found this worm in our yard in the Sacramento area, and we haven’t been able to find it on your site. Could you please identify it?” is all this reader asks in her submission concerning the beige and brown, long worm with the spade-shaped head in the picture below.

“What the heck is this?” asks this reader about the brown, striped organism pictured below. “It’s easily 10-to-12-inches long, and found in Greenville, South Carolina.”

“Is this a hammerhead flatworm?” asks this reader for her friend in Southeast Texas. She is asking about the long, thin worm below, which is brown, with lighter brown stripes running the length of its body.

“What’s your advice about disposing of dead worms?” asks this reader in her query concerning the discovery of “flatheads” on her enclosed patio. She asks specifically if a “flathead worm” can “come back to life or reproduce” after it has dried out or died “on the cement”.

“I’m seeing these worms daily in my house,” says this reader about the creatures with “flat” bodies of around 2-2.6-inches and “thicker head[s]”. Our reader is growing uncomfortable as she fears the worms may enter her body and she asks for any suggestions we can provide as to how to prevent their entry into her home.

“I found a dead, black hammerhead worm in a shiny, clear substance in my garage. Does this worm secrete this substance?” asks this reader in her query. The photo she sent us displays a long, thin worm lying in a pool of the aforementioned shiny substance.

Two hammerhead worms were found on this reader’s patio in Oak Ridge, Tennessee within the span of two years. The first one is very long and black in color, while the second one is shorter, with a beige-brown body.

The hammerhead worm is a creature that fascinates many, mainly for its bizarre appearance. However, it seems as though little is known about these worms by the general public, and so this article will investigate just exactly what hammerhead worms are and how we should respond to them.
