The sea urchin is a cousin of the starfish . it moves with the help of its spines and its tube feet , which are arranged in 5 columns up and down its body . the tube feet end in minute suction pads , which are able to grip any firm surface with which it comes into contact 海膽屬于海星的近親,利用身上的短針及五行由上而下排列的管足移動身體,每條管足尾部長有一細小的肉趾吸管,遇到堅硬的地方,便會緊緊抓著。

With the rapid development of electronic technology , vlsi ( very large scale itegrate circuits ) is widely applied in the electronic equipments . the structure of vlsi is complex , and the density of tube feet is intensive , logic is complicated 隨著電子技術的飛速發展,電子設備中大量使用大規模集成電路芯片,其結構緊湊,而且電路的管腳密集、邏輯復雜。

Many different types but commonly with 5 arms , each with rows of tube feet with suckers , measures up to 15 cm across the arms 種類繁多,但一般長有五只星臂,每臂有一排管足,足上有很多吸管。

Sea stars move very slowly along the sea bed , using hundreds of tiny tube feet 海星借助于成百上千的管狀小腳,沿著海底爬行速度非常緩慢。
