An Australian teenager who went for a swim at a Melbourne beach and emerged with his feet covered in blood has stumped marine specialists.

Sam Kanizay’s legs felt sore immediately after he played a game of football on Saturday, so he decided to soak them at the beach.

About 30 minutes later, the 16-year-old walked out of the water with his feet and ankles covered in what looked like hundreds of small pin holes that had been bleeding profusely.

When he returned house, his parents promptly took him to the hospital.

Sam’s father Jarrod Kanizay mentioned hospital employees had no concept what type of creature could have brought on the injuries, so he went back to the beach the following evening with a pool net complete of meat and captured the animals he believes could have been accountable.

Mr Kanizay took a video of dozens of the tiny bug-like creatures chomping on the chunks of meat.

“What is definitely clear is these small issues definitely enjoy meat,” he mentioned.

Jeff Weir, executive director of the Dolphin Analysis Institute, believes the teenager may possibly have been attacked by crustaceans referred to as amphipods, which normally consume decomposing plant and animal scraps.

On the other hand, Thomas Cribb, a parasite specialist from the University of Queensland, mentioned it would be extremely uncommon for amphipods to bring about such in depth bleeding.

“It’s not a parasite I’ve ever come across,” he mentioned.

Meanwhile, marine specialist Michael Brown believes the smaller bugs consuming the meat in the video could be jellyfish larvae.

“I’ve never ever noticed something like this,” he told Channel Seven’s Sunrise programme.
