Australian scientists are hoping to recreate the smell of an oversized sea snail after discovering its scent strikes terror into the hearts of crown-of-thorns starfish.
If researchers can synthesise the smell of the giant triton it could one day be used to help control movements of the starfish, which pose a major threat to the health of the Great Barrier Reef.
Footage of lab studies show crown-of-thorns have a violent reaction when exposed to water the snails have been in. They immediately become agitated and try to scuttle away on their stumpy legs.
Dr Scott Cummins, from the University of the Sunshine Coast, says the scent could be a powerful weapon in fighting starfish infestations.
“It won’t kill the starfish but if we can disperse aggregations, particularly during spawning season where they need to be near each other to breed, that might significantly reduce numbers,” he says.
