Every now and then, those of us who work at Melbourne Museum receive a polite but slightly troubling email:
"The Preparation Department needs to undertake work today that may generate some odours."
I can’t think of another workplace where stench warnings are a regular occurrence. They’re intriguing, too, because I always wonder what they’re doing down there in the basement.
Our skilled preparators do much as their name would suggest: they prepare things, from animal specimens for research collections to intricate models for display. Their job combines elements of biology, taxidermy, sculpture and painting and their work area is a den of creativity and practicality that is stocked with tools and equipment and art supplies.
In mid-December, a Gray’s Beaked Whale (Mesoplodon grayi) unfortunately was stranded at Portland and died. Given the rarity of this species, and MV’s strength in the study of whales, its skeleton is a valuable addition to our research collection. The preparators perform the somewhat gruesome but necessary task of cleaning the skeleton, and that’s where the odour comes in.

Preparator Steven Sparrey explained the facilities in which large specimens are prepared. The specimens are placed in a sequence of water baths in the ominously named ‘maceration tank’ which allows the animal’s soft tissues to loosen away naturally from the bones without damaging them. It’s not pretty and it doesn’t smell good. After this, the bones are given a soapy wash and dried thoroughly.

Some astonishingly large vertebrae from the backbone of a whale were on the drying racks. These were prepared for the Melbourne Aquarium from another stranded animal. The bones were quite yellow and Steven explained that the stains are from the whale’s oils, and they would be bleached by the sun once they were properly dry.

Shortly after that, he firmly suggested that we leave the area because the smell tends to cling to clothing. Needless to say, he doesn’t wear his work clothes home on the train. So there you have it – perhaps not one of the most glamourous jobs at the museum, but an essential task to maintain Victoria’s collection of our state's fauna.
