您应该绝对了解河豚骨架

一切都始于此推文。

那么,除了真正的甜蜜进化,您还能看到什么?

您正在看的是由纳米晶羟基磷灰石,蛋白质(胶原蛋白)和水组成的河豚刺,与鳞片的材料相同。的确,这些刺仅仅是被修改的标度。与其他鳞片一样,这些棘在发育过程中起源于真皮或皮肤的中胚层。

俄勒冈州立大学鱼类副教授兼鱼类策展人Brian Sidlauskas博士指出,河豚是从一组鱼类(豪猪,软体动物,引金鱼和斑鱼)进化而来的,这些鱼类都具有类鳞茎鳞片,在其外缘上有小齿表示。“Filefishes实际上感到模糊。所以不是’想象那些规模不断扩大并变得越来越棘手也许太令人惊讶了。”

如您所料,这些棘突演变为反掠食者防御,类似于河豚的膨胀能力。然而,看起来通货膨胀可能在尖峰之前就已经发展了。

进化是惊人的。

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 上 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 上 National Public Radio, Discovery Channel, Fox News, 国家地理 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 上 the Web.

  1. 好极了!!!并有可能解决一个谜团,该谜团是在俄勒冈西北部的Keasey地层(始新世晚期)发现了一些奇怪的三角异物之后使我们中的一些人陷入困境的。这些化石几乎完全符合脊柱的形态。

    其他想法是这些可能来自食肉海绵。这些没有’会与酸发生反应,所以它们不会’t calcite. They didn’看起来完全像是海绵状的玻璃质材料。

    在始新世晚期,太平洋西北地区有河豚!!!

  2. Or……也许他们没有“evolve”。他们有100%的机会最初是由想到它们然后创建它们的那个人那样制作的。
