来自Mbari: 这是一个蠕虫?新名叫蠕虫的这张照片显示出它的嘴巴,这通常面向下方,因为动物漂移在海面下方约1,000米(3,300英尺)。 图片:Karen Osborn(C)2006 Mbari

图片是一个新的海洋蠕虫, Chaetopterus pugaporcinus., 这是1000米的停留。 它的拉丁名称转化为“Chaetoptorid蠕虫看起来李的臀部。 它具有像其他多层的段体,但中间段是膨胀的。 后侧和前部段抵靠充气段压缩。 其中一位作者,指出了与其他Chaetopterid蠕虫的幼虫相似,除了5-10x越来越大,因此它可能是成年人。 另一方面,尚未识别的人都有性器官,精子或鸡蛋,因此它可能是幼虫。 顺便说一下,那家族的蠕虫是一个分类管理,所以在作者可以把这种蠕虫放在家庭之前,他们必须构建一个系统发育来解决混乱。 蠕虫通过面向嘴巴向下饲料并展开粘液云,捕捉海洋雪。更多折叠的图片更多。 更多在mbari。

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.
