在深水山上发现的章鱼苗圃

水下山脉的山峰位于太平洋海面以下,深达四分之三英里。戴维森海山(Davidson 海山)离深渊平原上升1.4英里,长约26英里,宽8英里,是美国水域中最大的已知海山之一。戴维森拥有丰富的生活,包括大片泡泡糖珊瑚丛生的树林和玻璃海绵礁。海山上的生活如此丰富, 我们提出了将近十年 戴维森海山及其密集的无脊椎动物聚集可能是附近峡谷和加州沿海岩石露头的许多物种的来源。戴维森可能是许多物种的理想栖息地,从而使其种群得以爆炸。然后,这个戴维森海山(Davidson 海山)的摇篮可作为将个体迁移到附近其他不太理想的栖息地的来源。这个想法 戴维森作为生物多样性来源发挥了重要作用 在获得戴维森 2009年加入蒙特利湾国家海洋保护区(MBNMS).

诺阿,MBNMS和Nautilus最近进行的一次探险返回戴维森海山。戴维森(Davidson)的典型作品是生动地展示了生活。   八千多人的小章鱼 健壮的章鱼 被视频捕获 将岩石抱在沉思的位置。目前尚不清楚为什么这些章鱼将海山用作苗圃。海山周围的高电流可能带来更多的含氧水。其他动物的密集聚集可以提供丰富的猎物。这个老火山的裂隙,裂缝和岩石瓦砾可能为掠食者提供庇护。

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 太平洋地区 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.
