屁股munchers.

误报有些动物发泄他们的肛门。而且,不,我没有提到围绕后面挥动一只手的行为,以扩散辣椒蛋白的气体残余物。一些海星,海参,小豆荚,蠕虫和甲壳类动物都将巨大的水泵出来进出肛门。

你为什么要在确保一个干净的derriere之外做到这一点?

像生物坐浴盆一样穿过肛门的大量水,可能有助于排泄,但它也可用于呼吸。想想所有表面积可用于将氧气从水中漫射到身体中!或者肛门甚至可以用于喂食......

等等,什么?

用新出版的研究的话语(诚实对上帝这是纸的第一行),

“预计不会通过其肛门摄取食物。”

在成人海中黄瓜中克罗卡(已经为泄露和生殖器产品释放的缺乏进行双重责任)节奏地泵出大量的水进出。已经知道,这种泵送在高度分支的呼吸道树上带来富氧水。因此,Cloaca现在正在拉出功能三件。但Quadfecta怎么样?

威廉jaeckle和richard strathmann放置 Parastichopus加利福尼斯是海参的野兽,借入其共同称之为巨型加州海参,在水族馆中,用碳的放射性同位素标记为含有单细胞藻类。在几个时间间隔,JaeChle和Strathmann看着海参内,看看放射性碳的位置。他们还用一些较大的铁标记分子重复。

在呼吸道树的组织中可以看到铁染色分子的蓝色斑点

经过一段时间,呼吸器树仅通过肛门接受外部水,是熨斗和放射性碳的绝佳。换句话说,食物通过肛门,被呼吸呼吸道。最高浓度在一个叫做他重温的机构中发现,以急剧树和肠道作为助力的运动。

所以,是的,海参可以通过他们的肛门吃。作者将更科学地称为“双相喂养”。作者确实如此,通过肛门采取的食物量可能很小,鉴于...... Ahem ...交换 水只有一个小时只是大约4杯水。

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.
