巨型管虫(Riftia pachyptila) 对硫化氢耐性强,可生活在火山附近。成体没有嘴也没有内脏,只靠居住在它体内的共生细菌提供能量。红色的呼吸器官可以吸收海水中的二氧化碳、氧气以及火山释放的硫化氢,把它们输送给体内的共生细菌,通过化合作用产生能量。环节动物门,多毛纲,管触目...
之【半冰半火】【巨型管状蠕虫(Riftia pachyptila)】我知道,它配轰焦冻是有点不好看(捂脸)。管状蠕虫是海底热液喷口的特有动物。海底热液喷口,分布在800-3500米海底深处,从喷口里不断流出含有甲烷、硫化氢和金属元素的热流,喷口温度可高达350℃,而海水温度近乎0 k...
深海巨型管虫(Riftia pachyptila)生活在海底热泉口,其体内没有消化系统,却能长到2米长。它们获取能量的主要方式是? 标签: 生物 常识 A、与共生的化能合成细菌交换营养物质 B、用红色羽鳃过滤海水中的浮游生物 C、直接分解海底硫化物进行化学反应 D、通过体表渗透吸收热泉中的溶解有机物 ...
Organization of the tentacular region in the giant vestimentiferan tubeworm Riftia pachyptila from hydrothermal vents has been reinvestigated. Protective cuticular structures consisting of a rod and a series of saucers have been found on the anterior surface of obturacula in juvenile individuals. This...

Riftia pachyptila Jones, 1981, lives in association with a chemoautotrophic, sulfide-oxidizing γ-Proteobacterium that occurs in a specialized organ, the trophosome. Ultrastructurally different bacterial subpopulations occur in different regions of the trophosome lobules (central rods, median small cocci,...
The deep-sea tubeworm Riftia pachyptila lacks a digestive system but completely relies on bacterial endosymbionts for nutrition. Although the symbiont has been studied in detail on the molecular level, such analyses were unavailable for the animal host, because sequence information was lacking. To id...
