Crabs exposed at low tide are at a greater risk of predation by definitive shorebird hosts than are hidden conspecifics.
This scenario agrees well with survival data suggesting a functional longevity corresponding to the duration of the low tide period.
The final hosts are oystercatchers that feed on the cockles during low tide.
The depth at low tide was 8 m at this cage.
At low tide, the vast intertidal zone is a major resting and feeding ground for large populations of endogenous and migratory birds.
Today some remains may still be seen at low tide.
Much of the foreshore along the coast comprises a shallow reef platform which is exposed at low tide and limits maritime access to the coast.
