Rescuers are combing beaches and islands in the search for 14 people, most of them Chinese tourists, still missing after their boat sunk off the Phuket coast on Thursday.
Somnuek Prempramote, the Third Region Navy commander, said on Sunday the operation to locate the missing persons, most of them Chinese tourists, is being simultaneously conducted on land and at sea. The search areas are between Koh Yao and Koh Phi Phi in the Andaman Sea, he added.
"Security authorities will check all beaches and islands," VAdm Somnuek said.
The covered areas are in Phuket, Phangnga and Krabi.
The victims were among the 105 passengers and crew members on board the Phoenix dive boat that capsized in rough seas and a violent storm off Phuket on Thursday. So far, 49 people have been rescued while 42 bodies have been recovered.
The Marine Department will try to salvage the sunken boat, VAdm Somnuek added.
Phuket governor Norapat Plodthong said the latest body was found inside the wreckage of Phoenix and retrieved by divers.
Divers from China on Sunday joined the search for the missing, including conducting deep-sea diving, after receiving the green light from Thailand, the China Daily reported.

Chinese ambassador to Thailand Lyo Jian told a press briefing in Phuket that the search mission will not end until every missing person is found. He reiterated China's commitment to cooperation with Thailand on the operation.
Prime Minister Prayut Chan-o-cha will visit Phuket on Monday to follow up on the search operation before flying to Tham Luang cave in Chiang Rai.
Tourists from China top foreign visitors to Thailand. Last year 9.8 million tourists from China came to the kingdom and they are on course to break the 10-million mark this year.
