This is the 'bone chilling' moment a colony of newborn African spiders turn to hunt their own mothers.
The footage was captured for David Attenborough's new series Parenthood.
In the never before seen behaviour, a pack of African social spiders are shown hunting in packs and responding to the vibrations of their prey as they struggle in the webs.
The spiders move in unison, starting and stopping at the same time, freezing together in a sinister game of musical statues.
Even more disturbing, after displaying their hunting skills on their usual prey of insects, the 1,000 strong colony then turns on their own mothers and eat them alive.
