Study Notes
Bioluminescence Overview
- Bioluminescence is light produced by living organisms, found in various environments: terrestrial, marine, and microorganisms.
Terrestrial Bioluminescent Organisms
- Fireflies: Common soft-bodied beetles, known for light display primarily during twilight for attracting mates.
- Mating Signals: Female fireflies can imitate male flash patterns to lure them as prey.
- Centipedes and Millipedes:
- Belong to the class Diplopoda, characterized by two pairs of jointed legs on most segments.
- They are generally venomous and carnivorous, possessing the ability to emit bright light as a defense against predators.
Marine Bioluminescent Organisms
- Anglerfish: Distinctive bony fish recognized for their predation method using a luminescent fin ray to lure other fish.
- Luminescence Source: The bioluminescence in anglerfish arises from symbiotic bacteria, usually obtained from seawater, residing in or around the fish.
