查询词典 gill raker

Generally, the figure of the one in the cave is smaller, the growing speed is very slow and the season growing is not obvious, mainly because of lack of food and the low temperature (around 15℃) in the karst cave water. In the numerable characters, the anal fin, scale of encircle tail and gill raker of the one in the cave are in the tendency of increasing so as to adapt to the narrow water passage in the karst cave, while the length of the cave Cyprinus carpio is lengthening comparing with the one on the surface.

结果表明：从总体看洞穴鲤鱼的体形比地表鲤鱼小，生长速度缓慢，季节生长不明显，主要影响因子是洞穴内食物贫乏和水温较低（15℃左右）；在可数性状中，洞穴鲤鱼的臀鳍条、围尾柄鳞和鳃耙有增多趋势，即增加了感觉细胞的附着基底；为适应洞穴水流域的狭窄通道，洞穴鲤鱼的体长相对地表鲤鱼而言有延长现象。
