Thin, Yellow Worm Could be a Canary Worm
May 22, 2022 5 Comments
"Can you tell me what kind of worm this is?" is all this reader asks in her submission regarding the long, yellow worm-like creature pictured below. Without any context as to the location it was discovered and to the concerns our reader might have with its discovery, it becomes very difficult to identify the organisms unless they are ones we commonly see and can identify solely by sight. Unfortunately, this is not a worm we have seen before (as far as we know), and so we will not be able to give a concrete identification. That said, we can still provide some educated guesses.

Long, Black and Brown Worms Found in Shower Could be Earthworms or Flatworms
May 19, 2022 1 Comment
"I have been finding 3-5 brown and black worms in my shower occasionally (every few days)", states this reader about the long worm-like organism pictured below. "I live in Virginia Beach, Virginia in a home built in the 60s. Sometimes these worms are brown and black combinations, sometimes they are all black. Last week one was alive in the shower while I was showering and it appeared to be attached to the edge of the shower with its mouth like a leach, while its body waved around in the water. They appear to be worms, however. I usually find them dead in the shower before I start the water; apparently they come up out of the drain after I shower and leave the bathroom, and then dry out and die once the water has evaporated. They don’t appear to be earthworms, and they’re too large to be drain fly larvae. I’ve attached a couple pictures of one I found a couple days ago. I will check back to see if anyone can help identify these guys. Thanks!"

We understand how our reader feels, as it is never a pleasant experience to find uninvited guests in one's home, let alone in one's toilet. And to confirm: yes, this is a hammerhead worm.

They are excellent trackers and possess amazing capabilities, such as the ability to regenerate severed body parts and to liquefy th…
