2. Agenda Definition of bioluminescence Research Goals Adaptations Attraction/Repulsion Reproduction Avoid Predation Future Research

3. Definition Bioluminescence - light emission from living organisms based upon a chemiluminescent reaction which is catalysed by a specific enzyme.

4. 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?

5. Origination of Marine Bioluminescence Where/When did bioluminescence originate from in marine life? 50 A.D.Pliny the Elder 1754Godeheu de Riville First description of phosphorescent ostracods (crustaceans). 1885French physiologist Raphael Dubois 1922E. Newton Harvey

6. Adaptations for bioluminescence Bioluminescence is used to aid organisms with the three essential aspects of life: Find Food Reproduction Avoid Predation

7. Adaptations for bioluminescence Attract Food Bioluminescence is used as a lure to attract prey by several deep sea fish

11. Research study

12. Research Different luciferins for different organisms.

13. Research

14. 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
