“I found this bright red worm in my bathroom sink (washbasin)”, writes this reader in her submission regarding the striped worm-like creature pictured below. “1) Should I be worried? Are they dangerous? 2) Did it come from the tap, therefore possibly from the house’s water tank? Or did it come up from the drain? 3) What steps should I take?” To start with, we want to compliment our reader on the fantastic photo, as well as the great questions she asked. They are all fantastic questions to ask when finding a worm, or any kind of unknown organism. In our opinion, this looks like it could be a California blackworm.
