普通乌贼:会变色,也会用墨鱼骨调浮力

奇妙动物志

普通乌贼 Sepia officinalis 属于头足纲乌贼目。它主要分布在东大西洋、英吉利海峡和地中海,也见于非洲西岸部分海域;常栖息在沙质或泥质海底,活动水深可到约两百米。成年个体的外套膜通常可达约四十五厘米。1
它有八条短腕和两条更长的捕食触腕,身体两侧的宽鳍能帮助悬停和缓慢游动。体内的墨鱼骨布满微小腔室,可以调节浮力;遇到危险时,它还能喷水推进并喷出墨汁。2
普通乌贼的皮肤拥有色素细胞和反光结构,能快速改变颜色、图案与表面质感,用于伪装和交流。它多在夜间活动,以甲壳类和鱼为主食;雌性把卵附在海草、贝壳或其它海底基质上,幼体孵化后很快就能自行捕食。普通乌贼通常只活一到两年。34
