Although the lifeform looked like it may have been a group of worms massing on something - it may have been just one.
Some speculated it was Lineus longissimus, AKA the Bootlace Worm, a highly toxic worm that can stretch to up to 180ft long. When handled it secrets a thick pungent mucus that smells like sewage as a defense mechanism, which can kill cockroaches and crabs.
Others speculated the whole thing was a PR stunt by Sony as a (very) viral promotion for the (hopefully) upcoming Venom sequel, once again starring Tom Hardy as the anti-hero.
As of now, the film is still scheduled for its October 2 release, with fans clinging to hope Halloween will not also get swept along in the coronavirus push back of cinema release dates
