The estuarine amphipod Corophium volutator exhibits an endogenous circatidal rhythm of swimming activity, with maxima occurring just after the expected time of high water, under constant laboratory conditions. Oxygen uptake by Corophium is also subject to modulation across the tidal cycle. The period of highest oxygen uptake occurs during the ebb tide, in phase with the period of maximum swimming activity. A second increase in oxygen uptake during the early flood tide is thought to reflect either in-burrow activity or a previously described rhythm of emergence. This being so, this aspect of the animal's respiratory metabolism may be regulated by an autonomous oscillator independent of that governing the animal's swimming behaviour.
在恒定的实验室条件下，河口双壳纲动物卷壳蜾蠃蜚表现出游泳活动的内源性潮汐节律，其最大值出现在预期的涨潮时间之后。卷壳蜾蠃蜚的氧气摄取也会在潮汐周期中受到调节。氧气摄取量最高的时期出现在落潮期间，与最大游泳活动的时期同步。涨潮初期氧气摄取量的第二次增加被认为反映了穴居活动或先前描述的出洞节律。既然如此，动物呼吸代谢的这一方面可能由一个独立于控制动物游泳行为的自主振荡器调节。
