(NECN: St. Augustine, Fla.) - Take a look at this swarm of worms, discovered in Vilano Beach, Florida.
Police in St. Augustine found thousands upon thousands of these bristleworms this week.
In this video, you can see them swimming around, in what marine biologists describe as a mating frenzy. That is typical for this time of year as the salt water has been getting warmer.
However, the number of worms seemed to decrease after a while as some fish were attacking them.
