Cubs Ceud and Rowan were recently returned to the wild
An otter rescue centre on Skye is marking its 20th anniversary.
Run by Paul and Grace Yoxon, the wildlife hospital at Broadford is also the base for the couple's International Otter Survival Fund (IOSF).
The centre's first casualty was a male animal that was hit by a car on 12 December 1988. Called Billy, he was later released back into the wild.
In September this year, a female cub found in Perthshire was the 100th otter to be treated at the fund's sanctuary.
Ceud, Gaelic for 100, was released near a mainland freshwater loch along with a male called Rowan.
Rowan, also a cub, was partially paralysed after being hit by a car but recovered well enough to be returned to the wild.
IOSF is also involved in promoting the protection of rare species abroad, such as Asia's hairy-nosed otters.
