Research advancements in echinoderm sensory functions and related receptors
The sensory system acts as a bridge between an organism's external environment and its internal signal system,responding according to the environmental stimuli and changes.It plays a crucial role in key biological processes such as growth,feeding,and reproduction.Despite having a radially symmetric body and radial nervous system,echinoderms lack a centralized nerve center.They mainly depend on sensory systems distributed throughout their bodies to perceive and react to their external environment.The unique taxonomic position and biological traits of echinoderms offer valuable insights for sensory system research.This review summarizes and discusses the methodologies of sensory system research,behavioral characteristics induced by the sensory system,and the dis-covery of related receptors in echinoderms.We aim to encourage future research regarding regulatory mechanisms of sensory systems in echinoderms'unique physiological behaviors and provide theoretical backing for the efficient and sustainable aquaculture of economically significant echinoderm species.
