水蛭养殖的感官包括光感细胞和感觉性细胞群。

　　Leech farming senses including light cells and feeling of cells.

　　光感细胞集中在头端背部的数对眼点上，这些眼的结构比高等动物的简单得多，仅由一些特化了的表皮细胞、感光细胞、视细胞、色素细胞核视神经构成，视觉能力较弱，主要色素感受光线方向和强度。一般来说，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.

　　蛭的触觉感受器对外界的水流、波动、震荡、温度非常敏感。吸血水蛭能根据水波相当准确地确定波动的中心位置并迅速游去，所以人在插秧时，双脚动得越厉害，游来的水蛭越多，有一句俗话说“蚂蟥听水响”，这是有理的。

　　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.

　　在有水蚂蟥的场所，只要用一根木棒在水中划动几下，就可以招引医蛭游来。但是石蛭科的种类对震动的反应是身体迅速缩短，与上述的吸血种类探索反应有所不同。

　　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.
