A large preserved bump-head sunfish specimen mounted on a scaffold frame undergoing conservation.

Don’t miss this rare opportunity to name this extraordinary Bump-head Sunfish and see conservation in action!

Collected at Manly Beach in 1882, this Bump-head Sunfish (Mola alexandrini) specimen has been part of the Australian Museum collection for over 140 years. One of the heaviest bony fish on Earth, it can weigh more than 2,000 kilograms. Like many other specimens in the Ichthyology Collection, this specimen AM I.2742 is used by researchers and decision makers globally to help us better understand our planets fish biodiversity.

Now, our conservator Kerry Etherington from the Collection, Care & Conservation team is carefully restoring this remarkable fish specimen. Because of its immense size, the work can’t be carried out in the lab - so it’s being conserved in the Australian Museum for visitors to see.
