摘要:

海绵是世界上最原始的低等多细胞动物之一，广泛分布于地球上的各种水体，由潮间带到深海海底，甚至淡水中都可见到。本文概述了海绵的外部形态、内部结构和生活习性等生物学特点，介绍了利用海绵高效泵水功能净化水产养殖水体和生物共生体系预防养殖病害的研究应用前景。

Abstract:

Sponge is one of the most primitive multicellular animals in the world, which distributes widely on earth, from tidal zone to deep sea bed, even can be seen in fresh water. This article outlines the biological characteristics of sponge， including external features, internal structure, life habits and so on. The article also introduces the prospect of using the high efficiency pump function of sponge in purifying aquaculture water and as parts of the symbiotic system to prevent aquaculture disease.
