An amorous octopus has been released into the wild so it can start its search for a mate.
Kali-Marie, a female lesser octopus, has been living at Macduff Marine Aquarium in Banffshire, for the last six months.
The single mollusc was donated by a fisherman and since its arrival has fascinated visitors and staff alike.
The sea creature learned to negotiate mazes, retrieve snacks from jars and deal with puzzles provided to keep it stimulated and happy.
But with a lifespan of only 18 months, and already fully grown on arrival, the team decided to let the octopus go so it can find a partner.
Aquarist Lauren Smith said: "I adored that octopus, absolutely adored her and worked really closely with her.
"But in a way I'm really happy she's gone back to the wild.
"I expect her to do really well because they don't lose their ability to predate naturally on crabs, which is their favourite food source."
Lesser octopuses are relatively common in Scottish waters, but they can be found in places ranging from Norway to the Mediterranean.
In recent years the North Sea populations have increased.
The creatures, also known as curled octopuses, have a broad, ovoid-shaped mantle and can reach a total length - including arms - of up to 50cm.
They normally breed towards the end of their life, which was part of the reason Kali-Marie was released.
