A whale and dolphin rescue group is trying to recruit more volunteers ahead of the opening of a new seal pup centre in the Highlands.
Grey seals are common around the Scottish coast
British Divers Marine Life Rescue (BDMLR) and Highland Wildlife Hospital are to run the sanctuary in Ullapool.
Ten places are still available on a training course for potential medics at Dores on Loch Ness on 17 June.
A two tonne inflatable mock-up of a pilot whale and life-size replica of a seal will be used during the exercise.
The Loch Ness marine medic course will include lectures on marine mammal biology and first aid at Dores Public Hall.
This will be followed by practical exercises on rescue techniques at the nearby Dores beach.
These include handling injured and stranded animals, first aid, assessing injuries and re-floating of stranded dolphins and whales.
Twenty people have signed up for the course so far.
BDMLR were among the groups that battled in vain to rescue a whale stranded in the River Thames last January.
The female northern bottle-nose, which died, was the first of the species to be found in the river records began in 1913.
