阅读下列短文，然后回答问题：

夏季在海滨游玩，若赶上退潮，在礁石之间的水洼中，往往能见到海葵。海葵呈圆柱形，十分柔软，极易收缩。它吸收水中的氧，将废物排到水中，它的一端是口，口的周围有口盘，口盘周围环状地分布着好几圈触手，用来捕食海水中的小型浮游生物，如原生动物、单细胞藻类等。触手中包含有丰富的刺细胞，当海葵受到刺激收缩时，枪丝常由口或壁孔射出，有防御及进攻的功能。海葵捕捉到食物后，从吸口中分泌出消化液，先把食物消化成液体再送入其消化腔内。海葵的受精卵发育成可游动的浮浪幼虫。数日之后，浮浪幼虫以反口的一端固着，发育成新的海葵。海葵也可以纵分裂或出芽生殖，往往形成群体。

海葵是生物吗？请说明明理由。
