Two survivors of the tragedy face an uncertain future in the jungle now
Last week, Thailand suffered one of its biggest ever single elephant tragedies, when 11 animals in one family died in a swollen river.
At first only six elephants were thought to have died - days later another five were spotted downstream.
The initial theory from park rangers in Khao Yai National Park was that they died in a rescue mission. As they crossed the treacherous 150m-tall Haew Narok - or Hell's Falls - a baby slipped and the others fell trying to save it.
Though the loss of 11 elephants isn't catastrophic to the species, there is something about them that draws us in, and this apparent self-sacrifice struck a chord around the world - millions of you read our story alone.
But emotions aside, how plausible is it that elephants would have both the empathy and skill to risk their lives for a baby? And perhaps more importantly now, what does this mean for the survivors?
The elephants had fallen at least 80m down 'Hell's Falls'
Dr Joshua Plotnik, assistant professor of psychology at Hunter College City University of New York, has been studying elephants in Thailand for more than a decade.
He told the BBC that with no witnesses, we can't assume what happened. But he says it's "certainly reasonable to suspect that when an elephant in a family group is in danger the other elephants might do everything they can to go help".
There is well documented evidence of elephants recognising danger and co-ordinating their actions to stage a rescue.
But Dr Plotnik says it seems unlikely that they would "actively all go over a waterfall in a dangerous situation like that".
It was more likely a terrible accident.
The elephants were spotted lying below the falls in the rushing water
Dr Rachel Dale, an elephant behaviour specialist at the University of Veterinary Medicine in Vienna, agrees that elephants will unquestionably help an elephant in danger, "even if it's at a cost to themselves".
But they're also "smart animals, really smart", she says, so probably have the ability to carry out a kind of perfunctory risk assessment before rushing in.
Notoriously dangerous
Bhichet Noonto leads the Thailand Human-Elephant Coexistence Project at the office of Thailand Science Research and Innovation, studying patterns of elephant behaviour.
He said conditions in the park were miserable at the time of the accident, and Haew Narok was already a known hazard to elephants in the monsoon season.
In 1992, eight elephants died after tumbling over the same falls - park officials have said they witnessed a mother on that occasion jump in after a baby. A calf is also suspected of having fallen off a cliff there in 1987.
Concrete fencing has been put up to try to keep elephants away from dangers
Park staff try to keep them clear of hazards, but can't be successful all the time
To prevent further accidents, park officials constructed miles of concrete pillars to steer them away from hazardous places.
But they couldn't cover everywhere, and the rangers have seen footsteps indicating this group had followed one fence all the way up the falls until they found a way through, right at the top.
