hydra is a coelentrate marine organism. it has a unique digestive system which is both extracellular & intracellular. first the ingested food is digested extracellularly & then intracellularly. extracellular digestion takes place in the body cavity of hydra which is called coelentron by the digestive enzymes secreted by gland cells of endodermal layer which is called gastrodermis. then the partially digested food is engulfed by the cells of gastrodermal layer in the form of food vacuoles. further digestion takes place in these food vacuoles.
