Evolution of Bioluminescence of Deep Sea Organisms By: Selisha M. Cherry Bio 425 April 19, 2011
Agenda • Definition of bioluminescence • Research Goals • Adaptations • Attraction/Repulsion • Reproduction • Avoid Predation • Future Research
Definition Bioluminescence - light emission from living organisms based upon a chemiluminescent reaction which is catalysed by a specific enzyme.
Research Goals • Where/When did bioluminescence originate from in marine life? • What adaptations have come from the evolution of bioluminescence? • What does research show about bioluminescence?
Origination of Marine Bioluminescence • Where/When did bioluminescence originate from in marine life?
Adaptations for bioluminescence • Bioluminescence is used to aid organisms with the three essential aspects of life: • Find Food • Reproduction • Avoid Predation
Adaptations for bioluminescence Attract Food • Bioluminescence is used as a lure to attract prey by several deep sea fish
Adaptations for bioluminescence Reproduction
Adaptations for bioluminescence Avoid Predation
Research • Different luciferins for different organisms.
Future Research • The common ancestry of bioluminescent organisms is unknown. Current research in this field hopes to yield the answer to this question, unlocking one of the greatest scientific mysteries of modern time. • New avenues focused on chemistry • Anti-bacteria agents • Cancer fighting agents • Testing for the presence of life on Mars • Detecting pollutants in our waters
