Sam Kanizay, a 16-year-old teenager, living in the area of Melbourne, Australia, whose active family participate in triathlons at the ocean, went for a half-hour swim after his football practice on Saturday and ended up bitten while listening to the music of his iPhone.
But Walker-Smith told the ABC's RN Breakfast program the amphipods posed no risk to the public and that it was safe to go back into the water. The results of Jarrod's experiment may provide the answer to why Sam's legs were bleeding from tiny holes.
Upon returning home, the injuries left his parents puzzled that they chose to take him to the hospital.
Sam, who was rushed to hospital, said doctors could not explain what had caused the injury. Nobody could figure out exactly what attacked him. The exact cause is a bit of a mystery, but tiny sea crustaceans may be to blame.
The incident has sparked a number of different opinions across the marine industry as to what could have caused the bites - with one expert believing the small bugs could be jellyfish larvae.
The culprit was most likely some sort of tiny sea creature.
Associate Professor Reina said sea fleas were common in waters but had a theory about why they may have been hanging around Brighton on the weekend. At first, Kanizay's physicians thought his injuries were an unusual case of starved sea lice bites. But when he stepped out a half-hour later, he noticed blood on his legs.

"They're mostly less than a centimetre long, and so the bites they make are pretty small, and so that's more consistent with pinprick size marks".
The teenager "had to have really really cold, and it is for that that he has not felt", said Mr. Weir, who had already had scratches similar on the front after a diving in the night 40 years ago. Those aren't necessarily what attacked Kanizay at the beach. "They're used to eating dead things still on the bottom [the ocean floor]".
"I didn't feel anything untoward when I was in the water", he told the Herald Sun.
Sam remained in the hospital Monday recovering from the wounding.
Australians tend to roll their eyes when the world obsesses about this country's risky animal kingdom, including its deadly snakes (the deadliest in the world), its tiny and toxic redback spiders, and of course the jellyfish that cause heart attacks.
Sea lice are parasitic creatures, called copepods, which feast on various fish species in the southern Pacific and in the Caribbean.
"If we didn't have them, we would have a sea filled with dead and decaying fish", she said. Let us know in the comments.
