Fireworms, or bristle worms as they’re sometimes known, carry venom-filled bristles that cause intense pain on contact. Their unique and painful sting has made them a top concern for anyone planning a beach day.

Under the Microscope

Described by the National Park Services as having “tiny, needle-like spikes, each one filled with venom,” these worms pose a real threat.

The Sting That Burns

A brush with a fireworm can leave you in hours of pain.

Their bristles release neurotoxins as a defense mechanism, which unfortunately also means agonizing pain for unsuspecting humans who touch them.

After the Sting

“The sting site can feel sensitive for weeks,” notes the Harte Research Institute on Facebook.

This highlights just how much of a nuisance these stings can be, long after the initial pain fades.

Unusual Findings

Interestingly, these worms have been spotted on logs covered in gooseneck barnacles.

This could indicate that fireworms use these logs not just for transport but as a food source, providing a glimpse into their role in the marine ecosystem.
