An eight-year-old boy was rushed to hospital after being bitten by an adder snake on a British beach.
Jake Closier was on a day trip to the beach in Norfolk when he was attacked by the venomous snake, which caused his hand to swell up "five times the normal size".
The young boy was with his dad Kenny, 33, and mum Sophie, 32, at the popular beauty spot Hemsby beach in Norfolk, when the snake took aim at him whilst he was playing in the sand dunes.
At first, Sophie thought the bite was from a benign grass snake, but quickly realised it was much more serious when Jake's hand went "completely hard".
Sophie, from Camden Town, London, said: "We were talking a family walk along the beach to look for the seals and were heading towards Winterton.
"My son was running around on the beach in the sand dunes and he fell over and was bit by the venomous snake.
"He was in the wrong place at the wrong time. It was our first time there.
"I wasn't aware that there were any venomous snakes in the UK that were wild. There were no warning signs on the beach or sand dune.
"I noticed that my son had been bitten and managed to take a quick snap of it on my phone.
"I've had domestic snakes before and I have been bitten several times by non-venomous snakes when they were babies. It is nothing worse than a hamster bite.
"My first thought was that he has been bitten by a grass snake, so we walked to a medical centre in case he needed a tetanus jab.
"Within about 30 seconds, I checked his finger and it went completely hard and I could see a puncture wound."
Panicked Sophie said she searched on Google for advice and learnt adders were present in the area.
She added: "I googled what the snakes were in Norfolk and straight away it said there were adders in the area.
"That's when I panicked because it finally clicked what type of snake had bitten Jake.
"We ran away from the sand dunes and knocked on resident's door so we could get an address for the ambulance.
"At this point, I did not know how serious the bite was.
"Luckily, a man drove us to the hospital as we were told we'd be waiting eight hours for an ambulance."
Jake was taken to James Paget University Hospital in Great Yarmouth, following last Tuesday's bite, where doctors inserted an anti-venom drip into his veins.
Sophie said: "We had to be at the hospital within half-an-hour, by this time his hand had swelled to about five times the size of a normal hand.
"His hand was so swelled and hard, we thought it was going to burst.
"The puncture wound was black. He was vomiting and sweating.
"The venom had shrunk his veins so they couldn't get the anti-venom into him properly.
"They somehow managed to get it in him within the hour.
"He was on the anti-venom for an hour and then had to have a flush and was on hourly observations for his heart rate, breathing and circulation.
"He had to have regular ECG scans too. He even had to have X-rays to check there were no snake teeth left in his fingers."
After being observed for 24 hours, Jake was allowed to return home - but is now suffering from "constant nightmares" and refuses to walk on grass.
Sophie said that people should be "aware of the threat" of venomous snakes.
Adders are the only venomous snake in England and it remains rare for them to bite people, according to the Woodland Trust
Sophie added: "Jake could have died from it. It was so scary.
"The following day, the venom had already gone through his body so we had got over the risk of him losing his life.
"There was still a danger he could have lost his fingers, hand or arm because he developed fluid retention in the tissue.
"His was in so much pain after they tried to stop the poison getting to the heart. That took about four days to go.
"We just want to warn people about adders when they are on sand dunes. Just look what can happen."
