aplacophora. 是一类由大约320种的软体动物。当它们被移动到Mollusca时,它们被认为是Echinoderms直到1987年。 物种摄取沉积物,同时居住洞穴。 缺乏壳,但表皮分泌了一个角质层,其中嵌入鳞片(上面看)的那一点。 后端(右)含有CTNedia(鳃,可以在照片中看到作为蓬松的材料)和肛门的蓬松材料)和肛门。也可以看到位于前(左)的嘴(右端右侧的平坦区域)。内部结构是肠道和后部是肠道和性腺的组合。 这个个体(亚类Chaetoderma)长约3mm。

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.

  1. 所以它到1987年才注意,Aplacophorans患有射线和科尔蒂菊酯,而不是马德勒氏菌,乌恰触手或富士小管(唯一可能属于这兽可能属于的孤岛典型的孤独中的唯一可能的棘手形式)?!?

    奇怪的…

  2. 它实际上并不奇怪。几个特征性的软体动物器官系统不存在:缺乏明显的头孢菌,没有感觉的眼睛或触手,没有排泄器官或歌剧,有些物种缺乏射频。非常少数人实际上(可能不到5岁)在分类学和过去30年内工作。

  3. 我可以了解软体动物字符(或缺乏)的混乱,但我’不买棘皮药!也许是sipunculun或寄生的东西或其他东西,但不是echinoderm…。但后来,后见证是20/20吧?我有兴趣看到1987年的纸张,是斯凯尔马纸吗?

  4. 是的,Aplacophorans曾被分类为妓女,但在1800年代后期,他们将被认为是多世纪以上的软体动物,’S,不是1987年。这似乎是一个常见的错误,也许来自维基百科的不正确上市。

    Graff(1875)往往是第一个识别属于软体动物的Alacophorans的信誉。许多其他作者在1870年代后期’S正确放置在软体动物内的血糖素。 Pruvot(Comptes Rendus CXI,第689-692页)研究了Aplacophoran的胚胎学,并确认了其发展的相似性对另一个软体动物的往外的往外因的疗法植物。

  5. 谢谢你的澄清汤姆。我真的很担心它可能已经占据了1987年的研究人员注意到软体动物的亲和力。

  6. 这些更正提出了一个问题:如果一个更改发布文本以纠正错误声明,或将其留给评论?
