这些是我最喜欢的几种:食肉海绵

大多数海绵是洗碗清洁剂和脏器吸收剂的灵感来源,它们通过将水过滤通过许多孔和通道来喂食。它们的学名Porifera,字面意思是孔隙载体。通道内衬有特殊的细胞,单核细胞,每个细胞都含有不断跳动的鞭毛。鞭毛的这种旋转作用从周围的水中过滤掉了养分和食物的细小颗粒。随着粒子的靠近,细胞像包裹在毯子中的小狗一样,通过将其部分膜包裹在周围而迅速吞噬。但是,在这种比喻中,小狗被狗大小的细胞消化。

隐喻地说,鞭毛和幼犬摄食是 sponges.  However, in the dark depths of oceans and in the black caverns of the marine caves, lurks Earth’s strangest creatures—the 食肉海绵s.

这个特写镜头几乎可以通过您花园中的花朵,但似乎是海绵– probably a “carnivorous sponge”头孢霉属。 Little Hercules相机在约1000米深度处捕获的图像。图片ID:expl5560,向太空航行–与NOAA一起探索海洋收集照片日期:2010年7月5日 图片提供:NOAA Okeanos Explorer程序,INDEX-SATAL 2010

大多数海绵是由针状的,少量的二氧化硅碎片组成的,可以提供结构。在食肉海绵中,海绵状科动物的某些针状形状像钩子。在海绵附近毫无防备的微小甲壳类动物或其他动物经常被钩在钩状海绵表面上的钩子上,很多 施穆茨 在魔术贴。在某些Cladorhizids中,co足类可能被粘着的表面捕获。一旦捕获了甲壳类动物,周围的细胞就会动员,覆盖并在甲壳类动物周围形成一个临时空腔。在该腔中,甲壳类被消化。这相当于蚊子被手臂毛束住,然后皮肤细胞在其上形成一层皮肤,最后您将蚊子消化到皮肤表面以下。

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 最 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.
