A world without professors or specialists or house–keepers with the profiles of policemen, a world which one could slice with one's thought as a fish slices the water with his fin, grazing the stems of the water–lilies, hanging suspended over nests of white sea eggs...How peaceful it is drown here, rooted in the centre of the world and gazing up through the grey waters, with their sudden gleams of light, and their reflections—if it were not for Whitaker's Almanack—if it were not for the Table of Precedency!

这个世界里没有教授，没有专家，没有警察面孔的管家，在这里人们可以像鱼儿用鳍翅划开水面一般，用自己的思想划开世界，轻轻地掠过荷花的梗条，在装满白色海鸟卵的鸟窠上空盘旋……在世界的中心扎下根，透过灰黯的海水和水里瞬间的闪光以及倒影向上看去，这里是多么宁静啊——假如没有惠特克年鉴——假如没有尊卑序列表！

I was keep going towards more details, particularly on fins, gill cover, anal fin, soft dorsal fin and caudal fin area within 2nd and 3rd level of subdivision.

我继续深入下去，尤其是在二级和三级细分下对鳍，鳃盖，臀鳍，背鳍软和尾鳍。

Without cephalic lateralis canals; vertebral count 10+16=26 (vs. 27); anal fin has 7-9 branched fin-rays (vs. 6-7); head had an irregular spot pattern which were joined together vs.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
