Dear Steve,
Looking in Freshwater Snails of Africa and their Medical Importance, Brown
D. 1980 it states that Tiphobia horei lives on muddy substrate from the
waters edge down to 100-125m and is particularly abundant on alluvial
sediment near the mouths of rivers. Elsewhere interestingly it states that
below 150-200m the concentration of hydrogen sulphide is toxic.
