A duel isotope (stable and radiocarbon) investigation of anchialine cave systems in the Yucatan Peninsula compares the food web of a coastal and an inland cenote. Isotopic data demonstrates distinct photosynthetic and chemoautotrophic trophic levels, as well as the ability of fauna within the cave to be selective feeders even within these nutrient poor environments.
