棘鱼

The Coelacanth is a fish that was thought to be extinct with the dinosaurs.

腔棘鱼是一种被认为和恐龙一起灭绝了的鱼类。

He instantly identified it as a coelacanth, a species believed extinct for 60 million years.

Smith先生马上鉴别出它是腔棘鱼，一种被认为6000万年前已灭绝的物种。

There are also sub species found of the Coelacanth but the real Coelacanth is found today in South Africa, Kenya, Tanzania and even the South Pacific.

还发现了腔棘鱼的一些亚种存在，不过真正的腔棘鱼现在只在南非、肯尼亚、坦桑尼亚和南太平洋。

Type genus of the Latimeridae: coelacanth.

矛尾鱼科的一个模式属；腔棘鱼。

Other ancient fish besides the arowana include the coelacanth, the starlet, and the knifefish.

除金龙鱼之外的其他古生物鱼还包括腔棘鱼、小星鱼和西刀鱼等。

This brute was brought up by fishermen off east africa and aroused the curiosity of the curator of a provincial museum, who sent a sketch of it to smith. he instantly identified it as a coelacanth, a species believed extinct for 60 million years.

这种鱼被渔民在东部非洲捕上来，随即引起省立博物馆馆长的好奇心，他寄给了smith先生一份腔棘鱼的素描图。smith先生立刻鉴别出它是腔棘鱼，一种被认为6000万年前已灭绝的物种。

When the researchers compared the human ultraconserved element to all the DNA sequences in the public database GenBank, the closest match was to DNA from the coelacanth -- an ancient fish thought to have gone extinct millions of years ago until a live specimen was caught in 1938 off the east coast of South Africa.

该鱼类一度被认为已经绝种，直到1938年在南非的东海岸又重新被发现。腔棘鱼是一种3亿6千万年海洋生物向陆地脊椎动物进化过程中至关重要的鱼类的后裔。虽然人类和腔棘鱼的演化从那时就分道扬镳，然后经过百万年的演化人类和腔棘鱼仍然共享着类似的重要基因片断。

Sarcopterygians are a group of prehistoric fish which are traditionally classed as lobe-finned fishes, which in the real world include the modern day lungfish and the coelacanth, Latimeria.

肉鳍四脚鱼是历前鱼类的一种，传统上把它归入圆鳍鱼纲。真实世界里的圆鳍鱼有肺鱼，腔棘鱼和矛尾鱼。

While purple-toed, keen-eyed hunters are just a made up example, a real animal that demonstrates this is the three-spined stickleback fish of western Canada. These fish moved into glacier-carved lakes thirteen thousand years ago.

当然有着紫色脚趾、视力好的猎禽只是一种杜撰的例子，不过可以证明进化这一点的真正的动物是加拿大西部的一种有三条脊柱的棘鱼。13000年前，这些鱼游进了冰荒湖泊。

Researchers expected that the gene responsible would vary from lake to lake. Instead, they found that each group of stranded sticklebacks had lost its armor by the same mechanism: a rare DNA defect affecting a signaling molecule involved in the development of dermal bones and teeth. That single preexisting variant--rare in the open ocean--allowed the fish to adapt rapidly to a new environment.

研究者希望不同的湖之间相关的基因有所差别，可是，他们发现每一组搁浅的棘鱼都通过同样的机制失去了它们的装甲：一种罕见的DNA缺陷影响了一个涉及皮内骨和牙齿生长的信号分子，这一个先前存在的变数——在开放的海洋中很少存在——使得鱼可以迅速适应新的环境。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
