Four million delicate objects ranging in size from a tiny beetle to the skeleton of a whale, are being packed up in a "mammoth task" at Cambridge's Museum of Zoology.
The museum is closing for more than two years for an £18m revamp and director Paul Brakefield says it is a huge challenge.
The museum will re-open as an interactive space telling the story behind the museum's collections.
