The search is continuing for the body of a teenager who jumped into rough seas to try and rescue a dog.
The teenagers went missing off Blackpool promenade
Police and coastguards set off at first light to hunt for the boy, who went missing off Blackpool promenade on Saturday afternoon.
The body of a 16-year-old, who also tried to rescue the animal, was pulled from the water on Saturday.
The alarm was raised by passers-by at 1530 BST after the pair, believed to be friends, got into difficulty.
Liverpool Coastguard co-ordinated a search using a Sea King rescue helicopter and lifeboats after the boys were seen struggling in the water near to Gynn Square.
The helicopter winched the body of the 16-year-old from the sea at about 1615 BST , near to the central promenade, a spokesman for the Maritime and Coastguard Agency said.
He was taken to the Royal Victoria Hospital in Blackpool where he was pronounced dead. The dog was also found dead at about 1745 BST.
The spokesman said on Sunday there was no hope of finding the other boy alive.
"We've got two coastguard rescue teams - 20 people in total - searching up and down the beaches on foot in the area where he disappeared.
"Unfortunately we're just looking for a body now," he said.
Search called off
A man, believed to be the father of the missing boy, arrived at the scene during the search.
He told a coastguard that the dog did not belong to his son, but said he was an animal lover, the spokesman said.
It is not yet known whether the teenager who died was the dog's owner.
The families of both boys were helping with the search on Sunday, which was called off temporarily at about 1200 BST because of the rising tide.
A spokesman for Lancashire Police added: "The deceased has been identified as a 16-year-old male from the Blackpool area.
"I can't release any further details regarding his identity as yet, as his family members have not been informed.
"The further male remains outstanding. He too is thought to be a teenager, again from the Blackpool area."
