Over millions of years, animals have had certain evolutions to camouflage, hunt, find mates…

They can get larger in size, become more flexible by living in many different environmental conditions, or change in behavior.

However, one of the interesting abilities of living creatures that still attracts the scientific world to this day is the mechanism of self-illumination of part or all of the body to serve the species’ own purposes. .

1. Snails

As one of the species with the ability to glow, the Clusterwink snail often hides in its shell when in danger and emits green light. At that time, the snail will look much bigger, making no enemy want to attack it anymore.

2. 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.

3. Millipedes

8 out of 12,000 millipede species are capable of emitting blue light at night. Their glow is to warn predators that they can secrete deadly cyanide, which is present in every pore of their body.

4. New Zealand glow worm

Glow worms are the common name for different groups of larvae and insects with natural bioluminescent characteristics.

Inside some caves in New Zealand there is a very special insect. They hang overhead, looking like strings of twinkling lights. This is essentially the larva of a winged insect.

While still in the larval stage, the worms cling tightly to the ceiling of the cave, then emit light and extremely thin silk threads that act like a spider web, helping them attract and catch small insects. attracted by light.

5. Firefly squid

The shelter of firefly squid is usually deep in the ocean, but every spring, they come close to the surface to lay eggs.

Each squid has dimly glowing spots on its entire body, including its tentacles.

However, a population of hundreds or thousands of squid can brighten an entire ocean area, allowing them to attract plankton and mates.

6. Crystal jellyfish

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

Crystal jellyfish are not only eye-catching, but they also play a very important role in science. For a long time, researchers have been able to take jellyfish proteins and combine them with genes from other animals to study and monitor.

7. Chameleon

Chameleons are creatures famous for their ability to continuously change color according to the season, weather and surroundings.

However, very few people know that under ultraviolet light, the bones of many chameleon species can also emit fluorescent light.

8. Mushrooms

According to statistics, there are more than 70 species of glowing mushrooms recorded in the world, most of which are concentrated in tropical areas.

The ability to glow in mushrooms serves many different purposes, the most common of which are: repelling enemies and attracting insects, which helps them spread spores.

9. Ankle-finned fish

Anglerfish (also known as anglerfish) are extremely strange and ugly creatures.

During the hunting process, the fish’s “fishing rod”-like part will glow, attracting small fish and plankton around it.

After that, their job is just to open their large mouth and swallow the entire prey into their stomach. This fish is called “the devil at the bottom of the ocean”.

10. Black arowana

This species often glows to attract prey. Victims caught in the trap will be devoured by the sharp teeth of this fierce fish.

In addition, black and female arowanas also have glowing organs scattered around their bodies.
