Protozoa, tiny body, red, transparent, spherical, with a single flagellum. Float in the ocean, can put phosphorescence, appear to make a lot of water into the red. With a split, sprouting, etc. breeding.

Noctiluca (noctiluca) is a type of protozoa living in seawater, under the flagella taxonomic classes, head back flagella. Fluctuations in the night because they stimulate the shiny water, hence the name. Noctiluca body is spherical, a diameter of about 1 hairs, the color red, cytoplasmic dense part of the sphere, the inner nuclear, cytoplasmic diffuse into other parts of the coarse mesh, the mesh are full of liquid. Has two flagella, a large, referred to as tentacles, the other smaller. It is the breeding method for the splitting and sprouting of two, which give birth to many small surface of the body of individuals, from the mother after the development into a new individual. For example, the diameter of flashing luminous insect body is 0.5 to 2 mm, the naked eye to see is one bright little ball, a transparent membrane, mesh scattered cytoplasm, dense nucleus, a small protruding flagellum and protoplasm the formation of thick movable tentacles. To be fat because the body contains many particles, so light when subjected to mechanical stimulation. Live in the sea worms and other luminous dinoflagellates (eg Gymnodinium waist whipworm, etc.) can cause red tide blooms, resulting in massive deaths of fish. In recent years, the beach water fish, shrimp continues to develop, in the breeding process to cast a large number of high-nutrition diet, who do not finish the residual material dissolved in water or sink in the sea, over time more and more, plus The extensive use of antibiotics destroy the balance of plankton in the water, a large number of industrial and agricultural and marine sewage continue to platoon, for these reasons that the sea constantly improve the nutrient content, such as the formation of red tide blooms protozoa provide a material basis. If you continue to drought, rising sea temperatures, making conditions such as temperature, dissolved oxygen, ph value, which qualify, the waist of the protozoan flagellum insects to reproduce rapidly, forming a red tide.
