2021603 10/02 - 15/02 Many animals can produce weak light, so-called bioluminescence, and this is potentially very important in the deep sea where there is a complete lack of sunlight. The importance is supported by studies finding up to 80% of deep-sea species being bioluminescent and many deep-sea animals also have eyes to detect the emitted light. This project will through behavioral and physiological experiments test our hypothesis on a novel function of bioluminescence based on our recent unique observation that a species of deep sea starfish has bioluminescent eggs, which putatively light up to be eaten and thereby dispersed. Another goal is for the first time to document natural bioluminescence from deep sea benthic living animals in their habitat in combination with observations of the correlated behaviors. The project will add new important knowledge about the functional significance of bioluminescence along with unique insight into life in the deep sea.
