Optical light is one of the wonderful abilities of creatures in nature.

1. Plankton

Plankton appears on most beaches around the world, especially in the Maldives. They emit blue light, and tend to glow more strongly when impacted by waves. When the tide rises, they gather together and create a beautiful scene like something out of a fairy tale.

2. Millipedes

8 out of 12,000 species of millipedes have the ability to emit blue light at night, normally they are brown. Although millipedes are organic detritus eaters and have no need to attract prey, their light actually serves to warn predators that they can secrete deadly cyanide from their pores. their feathers.

3. Fireflies

Fireflies are animals that have the ability to spontaneously emit light for many different reasons. Some fireflies glow to warn predators that they are mildly poisonous, while others glow to attract prey. The most famous place to find these brilliant fireflies is Waitomo Cave, New Zealand.

4. Snails

When Clusterwink snails are in danger, they will hide in their shells and emit green light. At that time, the snail will look so much bigger that no crab will want to attack it anymore.

5. Comb jellyfish

While other creatures emit blue or green light in the dark, this comb jelly emits light as it moves, creating a rainbow effect.

6. Fireflies

These creatures’ organs are located on their underbelly, signaling that they are looking for a mate, but their light also serves to warn off predators. This animal can emit yellow light.

7. Boys

This clam is about 7 inches long and has the ability to emit blue light. This special ability of mussels was discovered when the Roman Pliny saw that his breath emitted light when eating them.

8. Anglerfish

The female anglerfish’s dorsal fin protrudes just above its mouth, looking like a fishing rod. They have the ability to glow and attract prey. When their prey comes close enough, they will immediately attack their prey with their large jaws and sharp teeth.

9. Cockroaches

The two glowing spots on this insect’s back make it look like a poisonous beetle. Unfortunately, these newly discovered creatures became extinct due to a volcanic eruption near their habitat in Ecuador in 2010. They are the only animals that bioluminescent to mimic defense .

10. Mushrooms

In the world, there are more than 70 species of bioluminescent mushrooms, and they can be found everywhere. For some fungal species, light is used to attract pests, help disperse spores and stimulate their reproduction.

11. Squid

Many squid species emit their own light to match the color and intensity of the light above them. This helps them avoid predators, who will attack as soon as they see the squid’s shadow.

12. Coral

Most coral species have the ability to absorb external light and emit a different color of light than the color it absorbed. For example, many corals absorb blue or purple light, but after absorbing it, they emit bright red, orange, or green colors.

13. Octopus

Octopuses can glow continuously or flash and then turn off immediately in small holes below their bodies.

14. Starfish

Technically, they are not starfish, but Ophiochiton ternispinus is a closely related animal to starfish. Like their brothers, they also have 5 slender and very flexible legs. They emit blue light to attract prey in the dark.

15. Sea anemone

These sea anemones spend a lot of time floating around until they find a good place to anchor. Their tentacles stab at predators with sharp “harpoons”.

16. Lanternfish

Lanternfish have a light-emitting organ located under their abdomen, helping them emit light in the dark. However, this fish also has a light-emitting organ in its nose, giving it the ability to glow from the front like a headlight.

17. Bacteria

Insects are frequent victims of these bacteria, which kill their prey by releasing toxins until the animals die and break down their bodies from the inside out.

18. Molluscs

Krill are small crustaceans that live in abundance in the Arctic waters. The light they emit helps them find each other and gather, it also helps them escape other predators.

19. Sea snake

Sea snakes live deep in the sea, where they use their giant mouths to swallow larger prey. They can glow at the tail.

20. Deep sea

Swima bombaviridis is an animal with a very unique defense system. They can emit green light to distract predators, giving them enough time to escape.
