[3] This species is common in coastal mangrove forests, particularly near Avicennia marina trees, in western part of the Indian Ocean - Kenya, Tanzania,[4] Mozambique,[5] South Africa[5] and Madagascar.

There are large differences in the duration of flooding and sea level between the two high tides each day, between seasons and between places nearer to or further from the shoreline.

Then, one or two hours before the incoming tide, they start climbing on tree trunks and gather in groups of up to several dozen specimens, waiting above the water level until the sea recedes again.

In this case, the animal continues to climb as it would in its original surrounding for several more days or until it gets submerged, then the mechanism "resets" and it is again able to predict the oncoming high tide reliably.

[11] Since the cue used by these animals to predict the level of the incoming high tide is still a complete mystery, researchers jest that these snails can foresee the future.
