全部看到,都知道,颠倒的倒置藤壶

读者Jonathan W.用这个写入DSN

你们是海洋科学中最易于获得的一些,所以我以为我会造成这种令人难以置信的具体问题’多年来,我们唠叨了:我们都知道Nauplius有一种复合的眼睛,但我’曾经过于提及*成年人*藤壶留下一个可以感知光和黑暗的眼睛或眼睛位置......成熟的晶格结构是否拥有“eye?” If so, where is it?

乔纳森W.成人藤壶有一个眼镜。它是在甲壳类别额头的中间发生的第三只眼睛,并用宇宙能量对齐他们的节肢动物自我。

雄鹿饼是否看到宇宙能量绑定我们所有人?

虽然,成年钻石眼镜比宇宙眼要冷却得多。幼虫爬行,直到它找到一个有利的地方来设置商店。通常旁边的成年人已经挂了左右,因为没有栏杆想要独自一人。在这一点上,幼虫使用由第一天线分泌的水泥将它们的头部连接到岩石或其他硬表面。这触发了一种变态,使它们变成微小的成年人。基本上,一颗栏杆花了整个生命,做了一个小桶站,没有啤酒或圆圈男孩欢呼它。

看看这个栏杆的绘图我花了太多时间工作。

在这种变态期间,复方眼睛丢失,脱落幼虫外骨骼。它被3个叫做ocelli的群体所取代,其中3个大感受器。这些受体只有“开启”或“关”反应,并且可以检测光的存在或不存在。随着实验的尝试:浅水中的藤壶通常会在突然放在阴影时撤回和关闭。

Craig McClain is the Executive Director of the Lousiana University Marine Consortium. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (http://jiaxiangsuji.com/), a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.
