Future Research
DefinitionBioluminescence - light emission from living organisms based upon a chemiluminescent reaction which is catalysed by a specific enzyme.
Research GoalsWhere/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?
50 A.D.
Pliny the Elder
1754 Godeheu de RivilleFirst description of phosphorescent ostracods (crustaceans).
1885 French physiologist Raphael Dubois
1922 E. Newton Harvey
Adaptations for bioluminescenceBioluminescence is used to aid organisms
with the three essential aspects of life:Find FoodReproductionAvoid Predation
Adaptations for bioluminescenceAttract Food
Bioluminescence is used as a lure to attract prey by several deep sea fish
Adaptations for bioluminescenceReproduction
Adaptations for bioluminescenceAvoid Predation

Future ResearchThe 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.
