We investigated how large populations of several mysid species can coexist in oligo trophic underwater marine caves and their relationships in the marine cave food web using carbon and nitrogen stable isotopes. Isotopic signatures indicate food partitioning among the 5 species of cave-dwelling mysids from the northwest Mediterranean Sea we studied. Hemimysis speluncola feeds mainly on phytoplankton and zooplankton from outside the caves, Siriella gracilipes on sedimentary organic matter and zooplankton from outside, Harmelinella mariannae on small cave-dwelling crustaceans, and Hemimysis margalefi and Hemimysis lamornae mediterranea on sedimentary particulate organic matter. These differences in diet could promote coexistence of such diverse and abundant...
