Its rapidly beating cilia ( hair-like structures ) bring water-containing food to the rotifer . Technique : differential interference contrast microscopy .

它快速的鞭毛（头发状的结构）将水中的浮游生物带到轮虫中。

Professor terry snell in georgia tech 's school of biology , along with his students and collaborators at woods hole oceanographic institution , studied the partially-sequenced genome of the rotifer and located a receptor for a progesterone-like molecule .

乔治亚理工学院生物系的terrysnell教授同他的学生和伍兹霍尔海洋研究所的合作者研究了轮虫的部分测序的基因组，找出了一个类似黄体酮分子的受体。

But the females of certain rotifer species can do something quite unusual : they can reproduce asexually by creating clones of themselves , or they can initiate a process that allows sexual reproduction by producing male rotifers .

不过雌性的轮虫却能做不寻常的事：它们可以通过自我克隆来进行无性繁殖，当然它们也能通过有性繁殖来制造雄性轮虫。

But when unfavorable environmental conditions threaten -- such as the loss of algae food -- about a third of the rotifer population switches to sexual reproduction , which is the only way the creatures can produce eggs able to survive through a long winter .

但当环境条件对它们不利的时候（如藻类食物的消失），大约三分之一的轮虫就会转向有性繁殖，以卵来熬过冬天，这个时候这是该生物生存下来的唯一方式
