This species of snail is called Clusterwink, they are often found in clusters of snails stuck on rocky shores on Australian beaches. This snail is considered the strangest snail in the world because they can emit light on their own. Unlike land snails that secrete luminescent mucus, Clusterwink snails are bioluminescent based on a chemical reaction inside their bodies. When any creature touches it, it emits a green flashing light Until now, the ability of the Clusterwink snail to glow is still a mystery to scientists. They hypothesized that this could be a tool to help them raise alarms, communicate with their fellow humans, or frighten enemies Fireflies or glow bugs are small beetles collectively known as the family Fireflies that are luminescent. Fireflies are typical of temperate regions, although most species live in tropical and subtropical regions Fireflies are divided into two groups: flying fireflies and fireflies crawling on the ground. Both of these groups can emit the same special cold light, which does not radiate heat like artificial light The light of fireflies is emitted from the last few segments of the abdomen. During the day, these nodes are only gray-white in color, at night they emit subtle light through the transparent skin, with reflective cells that have the function of reflecting light out. Plankton occurs in most of the world’s beaches, especially in the Maldives. They emit a blue light, and tend to glow more strongly in the presence of waves This luminescent light acts as a signal to scare away enemies with color, an implicit warning to the enemy. On the other hand, it also distracts the enemy, distracting the enemy, the plankton uses that opportunity to escape. In addition, according to scientists, bioluminescent plankton is a signal to attract and support larger organisms to hunt copepods – enemies of plankton. Atolla jellyfish live in the depths of the ocean. They have 22 tentacles, one of which is larger than the others and is used to catch prey, this jellyfish is known as the “moving lamp” of the sea. Unlike many other jellyfish, the Atolla jellyfish when attacked will immediately glow brightly. The light it emits can illuminate as far as 91.44m At that time, larger species will be attracted to this light and rush to it. Then the hunter becomes the prey again and the jellyfish will take this opportunity to escape Atolla jellyfish often use tentacles to catch prey. When the prey has been captured by the tentacles, they swing back and forth until the prey has no resistance and then enjoy. The anglerfish, also known as anglerfish – literally “fishing rod fish”, this fish has a fleshy nodule that grows from the head to become a luminous organ that functions as a bait During hunting, this part of the fin will glow, making the fish around it attracted. After that, their job is just to open their large mouth and take the whole prey into their stomach It is known that Anglerfish are considered the “demon” of the ocean floor because they have extremely ugly but extremely sharp teeth, this fish often lives in the deep sea, without light. In the forests of some Asian countries, including Vietnam, people still often encounter glowing mushrooms. This mushroom has the scientific name Omphalotus nidiformis but is often referred to as the “ghost mushroom”. Ghost mushroom is considered a poisonous mushroom that contains illudin compound – a luminescent substance or phosphorous substance that causes poisoning to humans when ingested. Mushroom poisonings often occur in the winter and spring, when fungi grow and develop. Therefore, people absolutely should not go to the forest to pick wild mushrooms to eat Geckos are a famous creature, known to many people because they have the ability to change color continuously according to the season and weather. However, very few people know that, under ultraviolet light, the bones of many chameleon species are also capable of emitting fluorescent light. This strange millipede is a millipede, scientifically known as Motyxia sequoia. Scientists think this millipede evolved a way to glow in the dark to cope with the stress of life when living in a hot, dry environment. In addition to stress relief, the blue light emitted by the Motyxia sequoiae mat also warns predators that they may spew out cyanide. When the light this millipede emits is not enough to ward off danger, they also ooze toxic cyanide and foul odors from their small feet. This millipede is blind, so they cannot attract each other with light, nor do they use light to attract prey. The ability to glow is just an odd defense mechanism of this creature
