Ways of deducing information on physicochemical characteristics of anchialine caves from measurements of sedentary biota are investigated. First, photographs of Ficopomatus enigmaticus from two different anchialine caves are used to draw qualitative conclusions on water circulation patterns and organic loads of the two caves. Next, the ability of bioenergetic models to quantify average conditions in anchialine caves from information on abundance, distribution, morphological characteristcs, and individual growth rates of F. enigmaticus is discussed, and a development of a bioenergetic model is suggested.
