Parts of David Attenborough's latest series were filmed in a fish tank rather than in the wild, the BBC has admitted.
The beloved British broadcaster used tanks during key scenes that featured boxer crabs, skeleton shrimps and Banggai cardinalfish across the five episodes of Parenthood.
Airing its first episode on Sunday, August 1, the series promised viewers 'astonishing, never-before-seen animal behaviours in stunning ultra high definition, from the remote jungles of Bhutan to the grasslands of Botswana'.
The near hour-long programme by Sir David, aged 99, focuses on animal parents that are 'having to adapt to a world that is changing rapidly', with the creatures facing 'a unique set of challenges' that they must overcome.
It is the first BBC natural history series to focus on parenting, with the team using new technology to capture the weird and wonderful in the wild.
