An aquatic mammal said to have inspired ancient tales of mermaids has gone extinct in China, researchers have declared.
Only three people surveyed from coastal communities in China reported seeing dugongs in the past five years, the BBC writes.
Known as the gentlest giant of the ocean, the Dugong's slow and placid demeanor likely made it vulnerable to fishing and shipping accidents.
It still exists elsewhere in the world, but is facing similar threats.
Prof. Samuel Turvey, from the Zoological Society of London (ZSL), who co-authored the research study, said: "The potential extinction of the Dugong in China is a devastating loss."

Scientists at ZSL and the Chinese Academy of Sciences reviewed all historical records of where Dugongs were previously found in China.
They found that there had been no sightings verified by scientists since 2000.
In addition, the researchers turned to citizen science to interview 788 community members living in those identified coastal regions to determine when local people had last seen one.
On average, residents reported not seeing a Dugong for 23 years. Only three people had seen one in the last five years.
This has led Chinese researchers to declare the dugong extinct.
