A new video has been released of the 12 boys and their football coach trapped in a Thai cave, in which they say they are in good health
Smiling and at times laughing, they each introduce themselves one by one.
They were found on Monday after nine days trapped by rising water inside the cave, and have since received food and medical treatment.
But their rescue might take months, as they must either be taught to dive or wait for the water to recede.
The concern is that the rainy season has only just begun, so water levels in the Tham Luang cave will almost certainly continue to rise.
The video posted on the Thai Navy SEAL Facebook page shows the team draped in foil blankets to keep them warm.
Lit by torches and with divers sitting alongside, they each give their name and the traditional “wai” greeting, putting their palms together.
Rescuers are now considering how best to bring the group to safety, with officials saying no risks will be taken.
Rescuers are providing health checks and treatment and keeping the boys entertained, and officials have said none of those trapped is in a serious condition.
Emergency teams are trying to install a phone line so the boys can talk to their families, but attempts to do so failed on Tuesday.
Seven divers, including a doctor and a nurse, have joined the group inside the caves.
How did they get there?
The boys, aged between 11 and 16, and their 25-year-old coach went missing on 23 June. It is believed they entered the cave in northern Chiang Rai province when it was dry and that sudden heavy rains blocked the exit.
It is thought the boys could move through parts of the cave in dry conditions but rushing waters clogged the narrow passages with mud and debris, blocking visibility and access.
How were they found?
They were finally reached by two British rescue divers late on Monday, nine days after they entered the caves.
They were huddled on a rock shelf about 4km (2.5 miles) from the mouth of the cave.
The video of that first contact was also posted on Facebook by Thai navy special forces.
The boys are seen by torchlight sitting on a ledge above water, responding to the divers that all 13 were there and that they were very hungry.
How can they get out?
The Tham Luang cave complex is regularly flooded during the rainy season which lasts until September or October.
More heavy rain could see water levels rise and threaten the air pocket where the group has taken refuge.
Experts have cautioned that taking inexperienced divers through the dangerous corridors of muddy, zero-visibility waters would be very risky.
Other teams are still scouring the mountainside in the hope of finding another way into the cave.
