DESCRIPTION
Metridium is a common Sea anemone also referred as Sea flower. They are large, solitary, sessile, marine animals found along the coastal regions of Pacific and Atlantic oceans. The body is divided into an oral and basal disc. A large mouth is present in the centre of the oral disc and surrounded by a whorl of tentacles. The main body can be differentiated into a dorsal capitulum below the oral disc and a ventral or lower, thick-walled scapus or column. Both these portions are separated by a narrow collar. Basal disc is highly muscular and flattened, which remains attached to the substratum. They are unisexual, example, the sexes are separate and gonads develop on the mesenteries.
