water vascular system
water vascular system
Noun
pl: water vascular systems
This term is a specialized biological descriptor used almost exclusively in zoology and marine biology. It describes a unique hydraulic mechanism found only in echinoderms, such as starfish and sea urchins, distinguishing them from all other animal phyla.
Because it refers to a specific anatomical structure, the term is used in a descriptive, scientific register. It is rarely used outside of academic or technical contexts and does not have a metaphorical or colloquial application.
