Metabolomic analysis of coelomic fluids reveals the physiological mechanisms underlying evisceration behavior in the sea cucumber Apostichopus japonicus

Evisceration is a peculiar behavior that happens frequently in the processes of aquaculture and transportation of sea cucumbers. This behavior involves a complex physiological process and results in the expulsion of the digestive tract and other viscera. However, studies on evisceration are insufficient, and the identification of the internal regulatory metabolites and potential pathways of evisceration in the sea cucumber are therefore likely...
