Bioluminescence light appearance varies greatly, depending on habitat and the organism where it is found.
In marine bioluminescence there are 2 types of visible light spectrum namely blue or green, they cannot process yellow, red or purple ... because most are more sensitive to blue and green.
Most terrestrial organisms also show blue-green bioluminescence. However, there are many yellow light spectrum organisms, including fireflies and Quantula striata soil snail, which originates from the tropics of Southeast Asia.
There are several organisms that can glow in more than one color. Train worms. The worm's head glowed red, while its body glowed green. due to different Lusiferase causes bioluminescence to be expressed differently.
Luciferase is an enzyme. The interaction of oxidized luciferase with luciferin (as a producer of light) (added oxygen) creates a by-product, called oxyluciferin. More importantly, chemical reactions create light. That light is what is meant by bioluminescence.
Some organisms emit light continuously. Some fungal species present in decaying wood, for example, emit fairly consistent light, called foxfire.
However, most organisms use their light organs to blink in less than one second to about 10 seconds. This flicker can appear at certain points, such as a drop in salinity, can force bioluminescent algae to glow, for instance. These living lanterns can be seen as spots of pink or green in the dark ocean.
Adaptation
Bioluminescence is used by living things to hunt prey, defend against predators, find partners, and carry out other vital activities.
Defensive Adaptation
Some luminous species confuse the attackers. Many species of squid, for example, shock predators, such as fish. With surprised fish trapped, the squid tried to escape quickly.
Vampire squid shows this variation in defensive behavior. Vampire squid emit sticky bioluminescent mucus, which can surprise, confuse, and delay predators, allowing squid to escape.
When some animals release parts of the body, they release it in other animals. When threatened, some species of sea cucumbers can break down the luminescent parts of their bodies into nearby fish. Predators will follow the light on fish, while sea cucumbers creep away.
Offensive Adaptation
Bioluminescence can be used to attract prey or prey.
The most famous predator for using bioluminescence is probably anglerfish, which uses bioluminescence to lure prey. Anglerfish have large heads, sharp teeth, and long, thin, fleshy growths (called filaments) at the top of their heads. At the end of the filament there is a ball (called an esca) that can ignite anglerfish. Small fish, curious about the point of light, swim to take a closer look. When the prey sees the large, dark jaw of the anglerfish behind a bright esca, it may be too late.
