“This worm moves from both ends”, writes this reader about the black, worm-like creature pictured below. “It has suckers/feet that it moves along with. Hope you can tell me what it is and if it is dangerous.” To start with, we want to thank our reader for the excellent photos she sent in, the best one of which is the one we included. Since it is such good quality, we find it odd that we cannot see the “suckers/feet” that our reader refers to. To us, this worm looks completely void of any feet-like appendages.

“Can you identify this creepy thing? Thanks!!!” is all this reader writes in his submission to us. The “creepy thing” he is referring to is the long, black worm pictured below, with bulbous bulges protruding from the length of its body.

A concerned reader wrote to us recently about a long, black worm he found in his house. He is worried that his dog has “a terrible worm of some kind.” We are of course highly sensitive to his concerns, but the reader makes no explicit connection between his dog and the long, black worm he found. He merely mentions that he came home (and presumably found the worm) and is worried about his dog. He didn’t mention any behavior of the dog that implies it has a worm infection, nor did he say he saw the worm come from the dog’s body. We are therefore slightly puzzled why he immediately linked the worm he found to his dog. In any case, he only asked us to identify the long, black worm, so hopefully in helping with this we can provide some guidance.
