There are many luminous creatures in the ocean.
1. The reason these creatures can emit light is because there is a special chemical reaction in their bodies that can convert chemical energy into light energy. This reaction usually involves an enzyme called luciferase and a chemical called luciferin. When luciferin comes into contact with luciferase, a chemical reaction occurs, producing a glowing effect.
2. The reason luminescent organisms in the ocean can emit light is because there is a special organ or structure in their body that can catalyze this chemical reaction. The light organs of these creatures are usually located in their skin, muscles, or organs. When they need to shine, the cells of these organs are activated and produce light.
3. There are many types of organismsuminous organisms in the ocean, including many different groups of organisms, such as bacteria, plankton, fish, squid, etc. These creatures are capable of emitting light through a special chemical reaction in their bodies that converts chemical energy into light energy. This reaction usually involves an enzyme called luciferase and a chemical called luciferin.
Types of marine animals
1. Marine animals can be classified according to their living environment. According to the depth of the water, marine animals can be divided into shallow-sea animals and deep-sea animals. Shallow-water animals live in areas of shallow water, such as coral reefs, beaches, and estuaries, where they are often adapted to relatively bright light and warm water temperatures. Deep-sea animals live in areas of deep water, where light isextremely low, the water temperature is low and the pressure is high.
2. The eating habits of marine animals are also different. Some marine animals are herbivores, such as algae, kelp, and other herbivores. Some are carnivorous, such as sharks, whales and other carnivorous animals. Others are omnivorous and eat both plants and animals, such as dolphins and some fish.
3. Marine animals also have various methods of reproduction. Some marine animals are oviparous. After laying eggs, the young animals emerge from their shells. Some are viviparous, in which the baby is born after developing and forming inside the mother's body. Others reproduce by laying eggs and hatching larvae, like coral polyps in coral reefs.
4. In the marine ecosystem, each species has its specific role and function. Coral reefsns, for example, provide habitat and food sources for many marine species. Coral polyps build coral reefs by secreting a calcium shell, a process that requires large amounts of energy and materials. At the same time, coral reefs also provide scientists with an important window into the study of marine ecosystems and climate change.
Dalian Daheishi Fluorescent Sea Time
There are rays, dragon head fish, light-eyed fish, bald fish, dinoflagellates, luminous jellyfish, squid and some sharks. shine. The light produced by dogfish is an intense green phosphorescence emitted by numerous light-emitting organs scattered throughout the skin. There is some kind of shark, deadIt still glows after a few hours. General term for marine organisms that have their own organs and electrical cellstroluminescent (including luminous symbiotic bacteria) or which have glands capable of secreting luminous objects. There are many types of luminous organisms in the ocean, including plankton, benthic organisms, and swimming animals. The word “bioluminescence” comes from the Greek los (meaning life) and the Latin word Luminare (meaning luminescence). This is a type of chemiluminescence, which is visible light emitted when chemical energy is converted into radiant energy. Because it emits very little heat, it is also called luminescence.
The phenomenon of luminescence in fish is due to the distribution of certain luminous organs on the body. Certain special substances in these organs emit a kind of “cold light” during the slow oxidation process.
The light organ consists of four parts: glands, crystals, reflectors and chromatophores.
Some fishOns glow because they have luminescent bacteria that live in their own tissues, or they secrete a luminescent liquid called luciferin from their skin. The angles use this light to attract small fish and shrimp to feed.
The biological importance of luminescence: species identification, illumination, prey attraction and scaring off enemies.
The fluorescent sea in Dalian Black Rock Reef is best from late April to early May. Choose the time around the 30th day of the lunar calendar and the first lunar day. calendar when there is no interference from moonlight and when there is a north wind of level 2-3. There is no exact time for the fluorescent sea, its observation depends on chance.
“Fluorescent sea” refers to the phenomenon of bioluminescence berries, which refers to the phenomenon that non-plant, non-animate organismsailments and the like such as dinoflagellates that congregate in certain berries emit fluorescent light and illuminate the berry. .
Regarding the magical fluorescent marine phenomenon, Cai Hengjiang, associate professor of the Science and Technology Education and Research Bureau of Dalian Ocean University, explained that it is the light released by microbial dinoflagellates when disturbed by the outside world. . Cai Hengjiang said: “Generally speaking, seawater fluorescence is caused by some luminous organisms in the ocean. There are many jellyfish, shrimp, shells and algae that emit light. »
Experts from Dalian Oceanic University seawater specimens led to a preliminary conclusion that the fluorescence phenomenon in the Daokuishi sea area is caused by some dinoflagellates with their own luminescence capacity,as well as by certain harmless bacteria present in the ocean.
