腕足

arm一词亦指无脊椎动物的附肢或运动器官，如海星的腕、章鱼的触手和腕足纲动物的腕足。

The term may also denote the limb or the locomotive or prehensile organ of an invertebrate ( e.g. , the ray of a starfish or the tentacle of an octopus ) .

其显著特征是，岩石具残余生物碎屑结构，见大量腕足类、海百合茎、珊瑚等钙质生物假象，主要为mm级完整个体，密集堆积。

The prominent characteristic of the siliceous rock is the residual bioclastic structure , with plenty of silicified calcareous organisms , such as brachiopoda , encrinite caudex and coral , which are several millimeters in size .

而另外的第I-IV腕足的断裂强度分别是其体重的2.30、2.05、2.06和1.87倍；

The broken strengths of the other four arms are respectively as 2.30,2.05, 2.06 and 1.87 times as that of its body weight .

根据上述地层中珊瑚和腕足动物化石，推测它们当时是生活在正常浅海的生活环境中，大致相当于底栖组合BA3。

The brachiopods and corals in these formations may have lived in normal shallow marine environment and a Benthic Assemblage 3 assignment is suggested .

本雅明-霍齐纳（BinyaminHochner）和他的同事研究章鱼多年，尤其是关注他们灵活的腕足和身体运动的控制。

Binyamin Hochner and his colleagues had been working with octopuses for many years , focusing especially on their flexible arms and body motor control .

事实上，研究者正在于欧洲委员会STIFF-FLOP项目共享他们的研究成果，该项目致力于研发章鱼腕足形状的手术操作臂。

In fact , the researchers are sharing their findings with European Commission project STIFF-FLOP , aimed to develop a flexible surgical manipulator in the shape of an octopus arm .
