The family of a missing boy who jumped into the sea to try to rescue a pet dog is continuing the search for his body, coastguards in Lancashire said.
Alex (l) and Oliver were trying to save a dog
Friends and relatives of Alex Kazimir Yorke have been scouring beaches in Blackpool near to where the 16-year-old disappeared on Saturday afternoon.
The body of his friend Oliver Harvey, also 16, was found on Saturday after he drowned close to the town's promenade.
The two teenagers were swept out to sea while trying to rescue a dog.
Alex, from Charnwood Avenue in the seaside town, plunged into water by the promenade with his friend to rescue Oliver's beloved border collie, Sarah.
Police and coastguards said on Monday they did not expect to find him alive.

A spokesman for the Maritime and Coastguard Agency said coastguards had called off their search for the missing teenager.
The spokesman said: "We are not going to do any more searching because the body could be anywhere by now.
"The Lytham Coastguard team will be on their routine patrol, so they will of course be keeping a look out for signs of anything.
"The coastguards also had a call from Alex's grandfather this morning to say the family themselves and friends will be doing a walk along the beach."
The teenagers had been walking with friends along the lower promenade close to Gynn Square when the tragedy happened. The dog also died.
Liverpool Coastguard co-ordinated a search using a Sea King rescue helicopter and lifeboats after the boys were seen struggling in the water at about 1530 BST on Saturday.
Oliver's parents, Desmond and Beverley, of Carshalton Road, Blackpool, said they were "devastated" by his death.
Alex's parents, Garry and Wanda, said their son "excelled" in school and was hoping to become a vet.
The stretch of water where the boys jumped in is a notorious blackspot, and was the scene of a triple drowning in 1983 when three Lancashire Police officers died trying to save a man who went in after his dog.
