The sponge, Mycale laevis, when encrusting the lower surfaces of flattened reef corals, induces marked peripheral folding of the host colonies. This relationship, though facultative, has advantages for both associates. The sponge has a continually enlarging substrate that is free from competitive sessile forms. The coral may benefit from an increased feeding efficiency as a result of water currents produced by the sponge and it is protected from invasion by boring forms, notably clionid sponges.
当海绵 Mycale laevis 附着在扁平珊瑚礁的下表面时，会引起宿主群体的明显边缘折叠。这种关系虽然是兼性的，但对两个共生体都有好处。海绵有一个不断扩大的基质，没有竞争的固着形式。珊瑚可能会受益于水流动效率的提高，因为这些水流是由海绵产生的，它也受到保护，免受穿孔海绵等钻孔生物的侵害。
