Forget about sharks for a minute. Get them out of your head. Apparently, there are also voracious marine creatures ready to leave our legs covered in blood after a quick soak. A 16-year-old Australian attempted to alleviate some post-football soreness Saturday at Dendy Street beach in Brighton before noticing something was apparently chewing on his legs, the Guardian reported.

 

According to the teen's father, Jarrod Kanizay, the bleeding wasn't noticed until about 30 minutes into the soak. "He went back to his shoes and what he found was blood on his legs," Kanizay told reporters. "They ate through Sam's skin and made it bleed profusely." The teen was taken to a nearby hospital, where the severity of the bleeding proved confounding for the staff. "They've called a number of people, whether it's toxicity experts or marine exerts and other medics around Melbourne at least... [and] yep, no one [knows]," Kanizay, who later performed an experiment of his own using a net full of meat, said.

Though a definitive culprit for the incident hasn’t been determined, a leading theory is that 16-year-old Sam Kanizay was unfortunately in the presence of particularly aggressive sea lice. As with any form of lice, these so-called "sea lice" are not a source of fun for anyone. Typically, the New York Times noted in their report, sea lice—a.k.a. marine isopods—make a habit of serving as parasite to fish, not people. Other theories cited by the Telegraph center on jellyfish larvae and tiny shrimp-like crustaceans.

For his own experiment, Sam's father tossed a chuck of meat into the water and later shared creep-tastic footage of the outcome. However, University of New South Wales associate professor Alistair Poore said, the creatures shown in Jarrod's video were not sea lice. "You can attract a lot of animals in the sea with raw meat," Dr. Poore explained.

At any rate, we should all just stay inside forever.
