Bristle Worm

Dear Curious Salemites,
We have an image in our archives also from Oregon that we previously tentatively identified as a Marine Worm in the genus
Glycera, and this image from APhotoMarine supports that identification.

Update:  November 11, 2018
Thanks to a comment from Rusty, we were informed of the common name Bristle Worm.  We searched that and found The Chesapeake Bay Program site that indicates Bristle Worms are in the class  Polychaeta
and this information is provided:  “Bristle worms are soft, segmented worms found along shorelines, mud flats and shallow waters throughout the Chesapeake Bay and its rivers. … Bristle worms have soft, segmented bodies with tiny, hair-like bristles along each side. The bristles are attached to appendages called parapodia. Each body segment has one pair of parapodia, which vary in shape depending on the species. Most worms have a head with eyes, antennae and sensory palps.”   According to Scenic Oregon:  “Polychaete worms, of the group Polychaeta, are annelids (segmented worms) that have “legs”– called parapodia– with bristles at the ends.  Some polychaetes, especially types of tubeworms, resemble palm trees, with a plume of frond-like appendages at the head.  Of all the species of annelids, the vast majority are polychaetes, with around 10,000 known species.  Some common names for different types of polychaetes are bristleworms, clam worms, featherduster worms, fire worms, lugworms, palolo worms, Pompeii worms, sea mice,  tubeworms, and many others.  They live underwater in almost every ocean environment, from cold water to undersea volcanic vents, with some burrowing into the sand at the shoreline.”

Horsehair Worm

Dear Texas Master Naturalist,
Thank you for sending in your awesome image.  We are quite fond of both descriptive common names for this parasite.  Horsehair Worm is the name we are using to describe the image you submitted because the creature is stretched out and really does resemble a hair from a horse’s tail or mane, and we suspect the illusion might even be more startling given the opportunity to view the worm submerged in water.  The other common name, Gordian Worm, refers to the Gordian Knot of mythology that could not be untangled, and it is a perfect visual metaphor for a Horsetail Worm when it is contracted into a ball.  How long was your Horsehair Worm?

It was about 15 inches or maybe more if it had been straight. The stick to the right of it is my walking stick, which is about 1 in diameter.

We were walking the beach on Anna Maria Island in Florida when we came upon this fellow. It was right on the wet sand where the waves come up. Couldn’t tell where he came from or where he was going. Any ideas?

Bristle Worm

Dear Nan,
This Bristle Worm is actually an Annelid marine worm.  We found this matching image on Matthew Meier Photo and another on Florida Sportsman.

Hello! I’m hoping you can help me and see what this parasite is. It is white when exposed to air and dries. It is hard, almost like a twig, sometimes with a whip tail on the back and almost looks segmented but doesn’t appear to be the same as a tapeworm. Some sections of it splinters off, possibly male and female sexual productive pieces within the same worm. I’m not sure. It was found in human feces by the dozens. It can be roughly half inch long or longer. It does seem to break apart somewhat easily. I lived in Egypt for a year coming back about 7 months ago to the USA. It could have been caught at either location. Also, spent a night in Germany while traveling between. Thank you so much!

We do not have the necessary credentials to diagnose human parasites nor diseases, and we would urge you to see a professional for a diagnosis.  We cannot tell is this is an organism or if it is roughage.

Subject: Unknown Slug from Mount Santubong, Sarawak, Borneo
Location: Santubong NP, Sarawak, Borneo

Hi. Recently i went hiking at Mount Santubong National Park at Sarawak, Borneo, using the Summit Trail. I encounter this pretty blue black with white strip/bands worm on a tree trunk. It has a split in the middle too. As I’m a zoology student, I’ve ask around (lecturers etc) and they could only ensure me that it was not a platyhelmintes but some slug. I’m not sure about the elevation, but it was found after some 2280 m along the trail. And since I’ve no known experts to ask and my curiosity is giving me sleepless nights, I would like to try my luck here. It would be great if you know what this slug is. Thanks.

Hi. I’ve missed to input some details. Santubong NP is a tropical rainforest and the slug is about 5cm long,1 cm width. Thanks.



Dear Tan, C.F.,
This is not a Slug which is a shell-less mollusc.  This is a Planarian or Flatworm.  We located a very similar looking image on Photographers Direct, but alas, it is not identified as to its species.
  A video on Siam Answer does not provide an identification either.  A similar looking image on Project Noah is identified as a Hammerhead Worm, possibly in the genus Bipalium.

Found this worm hanging in an oak tree on July 20 by a silk thread. It is 5-6 inches long and iridescent in the sunlight. Can’t find any info about it, hoping you can help. Thanks.

Blue Worm: Hoax or Real???

Dear Carole,
We have no idea what this is, but it does not look natural and it appears to have been hung by a human.

So sorry to bother you.  I came to the same conclusion you did  this afternoon as I got more curious and decided to get a step ladder out and touch it.  Turns out it is a fishing lure.  I still have no idea how it got into a tree in my back yard.  My yard is fenced with no gate and I have several dogs (they are friendly).  I hung a chandelier on the next branch over not long ago and the worm was not there then.  I live alone and do not fish.  It is now a new mystery.  Thank you so much for your time.  A friend sent me to your site…it is really interesting.  Again sorry for sending you on a wild goose chase.   Carole

Don’t worry Carole.  Your submission prompted a robust dialog in our comment section and led to some nice links of “real” blue worms in various parts of the world.
