Behavioral variation according to feeding organ diversification in glossiphoniid leeches (Phylum: Annelida)

Abstract Adaptive radiation is a phenomenon in which various organs are diversified morphologically or functionally as animals adapt to environmental inputs. Leeches exhibit a variety of ingestion behaviors and morphologically diverse ingestion organs. In this study, we investigated the correlation...
