What ocean creature chewed up an Australian teen's feet?

Teenager Sam Kanizay's bloody legs after possibly being bitten by something while bathing at Brighton

The teenager said he went into the water to help his legs recover after a tiring soccer game, but ended up with far greater pain than when he went in.

Jarrod Kanizay took to the waters off the Dendy Street beach with a pool net last night, hoping to figure out what underwater monstrosity nibbled on his son Sam's legs.

Sam Kanizay lays in a bed with his feet bleeding.

"When he got out, he described having sand on his legs, so he went back in the water", his dad Jarrod Kanizay told AAP.

According to Jeff Weir, who is the executive director at Dolphin Research Institute, the injury could be likely caused by the bite of some amphipod, a tiny crustacean.

"What is really clear is these little things really love meat", Mr Kanizay concluded.

The story of Sam Kanizay, the 16-year-old that Hornsby referred to, wasn't foreign for Stevens, who was instrumental in beating the Eagles, picking up 27 disposals and 13 contested possessions. The teenager named Sam Kanizay had his ankles and feet all covered up in blood after being bitten by tiny flesh eating sea bugs. Con of living in Australia: There are sea lice that will apparently eat your skin off.

"As soon as we wiped [his legs] down, they kept bleeding", father Jarrod Kanizay said.

Despite the young boy's injury, Dr. Walker-Smith said that his case is unusual, possibly because he was standing still in the water instead of swimming, allowing the small animals to feed freely.

"We've had a few people just guessing it was sea lice ... but there was no real evidence to say what it was".

"I don't think there has been anything that has changed, there just aren't that many people that stand really still for that long".

"I've still got my feet today", Stevens said at a press conference on Monday.

"But throughout the process, he's been really positive and happy ... he's in good health and we expect a full recovery".

"[I couldn't feel anything] because the cold water basically numbed my legs, I felt what I thought was pins and needles", he said.

Sam was given painkillers and antibiotics and had blood tests.

Thanks to his video, experts were able to confidently identify the creatures as lysianassid amphipods, a type of scavanger shrimp-like crustacean commonly known as "sea fleas".

Besides sea lice, creatures that could be blame for the teen's injuries include amphipods, jellyfish larvae and a stringray.
