运动可以分为尺蠖式运动、蠕动和游泳三种方式。
Movement can be divided into inchworm type three ways, creep, and swimming.
尺蠖式运动和蠕动通常为水蚂蟥离开水体时及旱蚂蟥所采用,都是前后吸盘交替使用。
Inchworm type movement and peristalsis is usually used by the leech leeches water leaving the water and drought, suction cups before and after are used interchangeably.
不过尺蠖式运动先用前吸盘固定,后吸盘松公开,身体向背方弓起,后吸盘移到紧靠前吸盘处吸着,前吸盘松开向前伸展,如此交替前进,行进速度较快。水蛭种苗http://www.jntcyz.com/
But inchworm type movement with suction cups before, first after chuck loose open, among body arched, chuck moved to close to the first smoking a sucker, sucker to loosen stretch forward before, so leapfrog, speed faster.
蠕动是使身体平铺于物体上,当前吸盘固定 蛭物动方式较慢,但可穿行于土壤中,或从人的衣袜与皮肤 特之间的空隙穿进去吸血。水蛭养殖在陆地上常交替使用尺蠖,式运动和蠕动。
Peristalsis is to make the body flat out on the object, the current chuck fixed vermiculite objects move way slower, but can be through the soil, or from a person's clothing socks wear the gap between the skin and in blood. Leech farming on land are often used interchangeably inchworm, movement and peristalsis.
水蛭在水中常采用游的方式,即背腹肌收缩、环肌舒张,身体平铺如一片柳叶,波浪式向前运动(图2-7)。
Leech often adopt the way of swimming in the water, namely abdominal muscle contraction, ring back muscle relaxation, body flat out like a willow, wave (FIG. 2-7) to move forward.
