深海新發現：烏賊蠕蟲( Squidworm )

深海新發現：烏賊蠕蟲( Squidworm )





 

 科學家今天公開1種在印尼    與菲律賓    之間深海海域發現的輕飄飄詭異生物。


烏賊蠕蟲（squidworm）可長達9.4公分，外型比它的名字優雅許多。

它靠著擺動身體兩側細細、像骨牌排列的槳狀突出物，能垂直向上游動。

10根和身體同長，甚至比身體還長的觸鬚從它的頭部伸出，另外還有6對突出彎曲的頸背器官，負責烏賊蠕蟲的味覺與嗅覺。

美國    加州斯克里普斯海洋研究所（ScrippsInstitution of Oceanography）學者奧斯本（KarenOsborn）為首的3位海洋生物學家，利用遙控潛水器材在西里伯斯海（Celebes Sea）海面下2.8公里處，發現了這種前所未見的新生物。

科學家表示，烏賊蠕蟲棲息在海床上方約100-200 公尺的水域，那裡有許多尚未發現的動植物。

截至目前為止，該區域有很大一部分未經探索，因為採集工具有的只能順著海床刮取樣本，要不然就是採到的樣本都混在一起，拉到海面上後根本不能用，或是無法辨識。
============================================================
Compilation of 5 individual observations including 4 collection events (three with the suction sampler and one collection in the detritus sampler). Ventral view of animal followed by movement of the vehicle to the right around the animal giving a lateral, then dorsal view. The animal is slowly swimming initially and eventually becomes still. The second collection event (that with the detritus sampler) shows the animal at the time when it was disturbed to the point where it lost the aggregated marine snow it was attached to when it was first observed. The aggregated marine snow breaks apart and swirls around the animal and sampler as the animal comes in contact with the sampler canister.

This research was published in the journal Royal Society Biology Letters: The remarkable Squidworm is an example of discoveries that await in deep, pelagic habitats,by Dr. Greg Rouse, Dr Karen Joyce Osborn, and Dr Laurence P Madin.
