The skull of a fish with links to infamous grave robbers Burke and Hare is among a collection of intriguing items with fascinating back stories now on display.
The skeleton of a tiger that once belonged to a 19th century travelling circus is also part of the Science Behind the Object exhibition at the University of Aberdeen's Marischal Museum.
The exhibition offers a unique opportunity to see treasures from the University's museum collections that are not often on public display.
Objects and specimens on show demonstrate innovation and the extraordinary achievements that came out of Aberdeen over the past couple of centuries. They also tell colourful and bizarre stories.
Another example of this that can be seen is the carbolic spray that once belonged to renowned Scottish surgeon Professor Alexander Ogston.
His major achievement was the introduction of antiseptic surgery to Aberdeen Infirmary, which resulted in the discovery of the staphylococcus organism - better known as MRSA. Ogston introduced the use of the carbolic spray to combat it.
Exhibition Curator Carla Dobson said: "The exhibition gives the public an opportunity to see a vast amount of interesting objects that haven't been seen for quite sometime. These specimens explore the wonderful achievements of local Professors and important figures in history."
Science Behind the Object runs until September 30. Marischal Museum is located within Marischal College on Broad Street, Aberdeen. The exhibition is open Monday-Friday 10am-5pm, Sunday 2pm-5pm. Entry to the museum is free.
