Field-caught larvae of the estuarine crab Rhithropanopeus harrisii have a tidal rhythm of vertical migration when maintained in constant conditions. Laboratory-reared larvae do not show this rhythm. Endogenous tidal vertical migrations aid the retention of these planktonic larvae in estuaries near the parent populations.
在恒定条件下饲养的河口蟹 Rhithropanopeus harrisii 的野外捕获幼虫具有潮汐垂直迁移的节律。而实验室饲养的幼虫则没有表现出这种节律。内源性的潮汐垂直迁移有助于这些浮游幼虫在靠近亲代种群的河口处的滞留。
