水蛭養(yǎng)殖的感官包括光感細(xì)胞和感覺性細(xì)胞群。

　　Leech farming senses including light cells and feeling of cells.

　　光感細(xì)胞集中在頭端背部的數(shù)對眼點(diǎn)上，這些眼的結(jié)構(gòu)比高等動物的簡單得多，僅由一些特化了的表皮細(xì)胞、感光細(xì)胞、視細(xì)胞、色素細(xì)胞核視神經(jīng)構(gòu)成，視覺能力較弱，主要色素感受光線方向和強(qiáng)度。一般來說，水蛭是光的。

　　Light-sensitive cells on the back of the head end of the number of eyespots, these eye structure is much simpler than higher animals, only by some specialized epidermal cells, the photoreceptor cells, pigment cells, optic nerve, nucleus visual ability is weak, the main pigments direction and intensity of the light. In general, leech is light.

　　Awareness of cells distributed in leeches surface, also known as receptors, composed of specialized epidermal cells, its bottom end contact with sensory nerve endings, and at the head end and every segment of the central distribution. According to the different functions can be divided into physical receptors (receptors) and chemical sensors.

　　蛭的觸覺感受器對外界的水流、波動、震蕩、溫度非常敏感。吸血水蛭能根據(jù)水波相當(dāng)準(zhǔn)確地確定波動的中心位置并迅速游去，所以人在插秧時，雙腳動得越厲害，游來的水蛭越多，有一句俗話說“螞蟥聽水響”，這是有理的。

　　Tactile sensor of vermiculite, the rest of the world water fluctuation, shock, temperature is very sensitive. Leeches can according to the water wave fairly accurately determine the center of the volatility and swam quickly, so people at the time of planting, move your feet to the more powerful, to the more leech, there's a saying says "leeches water ring", this is right.

　　在有水螞蟥的場所，只要用一根木棒在水中劃動幾下，就可以招引醫(yī)蛭游來。但是石蛭科的種類對震動的反應(yīng)是身體迅速縮短，與上述的吸血種類探索反應(yīng)有所不同。

　　In the places where water leeches, as long as with a wooden stick in the water after a few times, can attract the medical &co. But stone monolayer of species response to vibration is the body quickly shortened, and the kinds of vampire reaction is different.
