Barchester Healthcare staff braved pythons, tarantulas and giant millipedes last month as part of a fundraising event to coincide with Australia Day.
Employees at Barchester's Inverness office expected to raise up to £700 for the charity's Healthcare Foundation, which aims to improve the quality of life for older people and adults with a physical or mental disability.
The animals, including geckos, beetles and hissing cockroaches, are more used to living in the Australian bush or the South American rainforests.
But, according to reports in the local Press and Journal newspaper, a Chile rose tarantula acclimatised fairly quickly to the shoulder of Barchester's accounts coordinator Kay Bone.
The Barchester Healthcare Foundation provides grants to individuals and organisations with health and social care needs which cannot be met by the individuals or by the public sector.
Australia Day takes place on January 26th every year and marks the date in 1788 when the First Fleet landed on Sydney Cove.
