Bioluminescence – a defence against enemies

A research team from the University of Gothenburg has now demonstrated in an article that the light intensity of bioluminescence is governed by how many enemies there are in the water. Despite the fact that many marine organisms glow, researchers know very little about why the organisms emit light and how the light is controlled.

“Bioluminescent organisms detect their enemies using their sense of smell and turn up the light when there is a great risk of being devoured,” says Jenny Lindström, at the Department of Biological and Environmental Sciences, who is the lead author of the article. “The light protects cells against their enemies.”
