Paper nautilus is a rare and enigmatic species of cephalopod which rarely graces the pages of Reef Builders, but when it does, it’s usually only一次一个标本。关于纸nautilus,其生活史或繁殖方式知之甚少,但是YouTuber大坝Nguyen的新视频可能对此有所了解。
The paper nautilus, also known as the Argonaut, is known from most of the oceans of the world, and unlike nearly all other cephalopods the Argonaut is a pelagic species, only found in the open ocean. The paper nautilus gets its name from the paper like covering that it secretes, not as a true shell, but is actually an eggcase in which the mother lives, mostly as a kind of pouch in which the young are brooded, and it also serves buoyancy duties.
最近共享的视频显示,在海峡群岛的加利福尼亚沿海沿岸的难以捉摸的纸质鹦鹉螺分组。您可以看到20件事兴奋地分组,分裂和重组,偶尔会脱离纠结对,我们合理地认为这是交配行为。
据我们所知,这是在视频中首次记录了这种纸nautilus,并以如此的晶体清晰起来 - 感谢现代水下拍摄设备的美好。与Nautilus,墨鱼和章鱼不同,由于它们的上层性质,就像鱿鱼一样,因此很少在水瓶座中保存纸nautilus。
但是,这是我们可以从远处和野外欣赏的一种物种,我们不介意坚持住宿的头足类动物来研究水族馆。未描述红色毛茸茸的章鱼不过是另一回事,希望我们将来能够更多地了解这种不可抗拒的物种。
