Australian schoolgirl survives deadly box jellyfish stings

Doctors in Australia have described their amazement at the recovery of a girl who was left unconscious after swimming into the tentacles of a box jellyfish.

Rachael Shardlow, 10, suffered horrific injuries to her legs and body when she came into contact with the jellyfish while swimming in an estuary in Queensland, Australia, in December.

The girl, who was pulled from the river with the stinging tentacles still clinging to her limbs, lost her vision and then stopped breathing and fell unconscious in the arms of her brother.

Jamie Seymour, who has studied jellyfish for 20 years at Queensland’s James Cook University told reporters the extent of the sting was “horrific”.

“When I first saw the pictures of the injuries I just went, ‘you know to be honest, this kid should not be alive’. Usually when you see people who have been stung by box jellyfish with that number of the tentacle contacts on their body, it’s in a morgue.”

Box jellyfish are the most dangerous and venomous jellyfish in the world. Adults can grow to 30cm wide with up to 60 tentacles that stretch up to 2 metres long. They are transparent in the water, making them exceptionally difficult to see. At least 63 people are known to have died from being stung by box jellyfish.

Each box jellyfish tentacle contains millions of stinging cells called nematocysts, which release venom on contact. Trying to remove the tentacles can cause more venom to be discharged. Death can occur within five minutes of being stung. “These animals kill humans faster than any other venomous animal we know,” Dr Seymour said.

Geoff Shardlow, the girl’s father, said his daughter still has scars and some memory loss. “The greatest fear was actual brain damage [but] her cognitive skills and memory tests were all fine,” he said. Doctors continue to monitor the girl’s recovery.

Scientists do not fully understand why box jellyfish are so lethal. The venom usually causes death by causing respiratory or heart failure, though it also contains chemicals that destroy skin cells, causing large and deep patches of scar tissue.

The Australian Venom Research Unit at Melbourne University recommends strict supervision of children who are swimming in areas known to be at risk of box jellyfish, as small children are more vulnerable to the jellyfish stings.

Freak jellyfish mishap:

SYDNEY - A SAILOR had an unlucky encounter with a deadly irukandji jellyfish in Australia’s northern waters after the tiny marine animal somehow hit him as he fished off a bulk carrier, officials said on Monday.

The Central Queensland Helicopter Rescue Service said it was not known whether the man reeled in the jellyfish, which is the size of a small fingernail, or whether it was splashed on to him by a freak wave.

‘He was splashed in the face but I don’t know that it was in that water,’ a spokesman for the rescue service told AFP. ‘It could have been something he reeled in.’

The man, who was an hour’s flight away from the Queensland coast when he was stung, was fishing from the deck of the carrier about 25 metres above the water level when he was stung by the extremely venomous creature.

‘Realistically, what are the chances of being stung by a jellyfish when you are safely on board a bulk carrier 25 metres above the water. It’s really incredible,’ said Geoff Abrahams, an air crewman on the rescue.

The man was taken to a Queensland hospital but survived his encounter with with one of Australia’s most deadly marine stingers. There’s no anti-venom for the irukandji’s sting and the pain may not be immediately felt, by which time symptoms have set in, including shooting muscle pain, vomiting, a rapid rise in blood pressure and occasionally heart failure.
