Gem anemone. Light micrograph of a transverse section through the body of a gem anemone (Bunodactis verrucosa). This section has passed through the pharynx (stomodaeum) region,showing the outer and inner epidermal walls,which are joined by septae (mesenteries,lines radiating inwards) which divide the anemone's body into compartments. Attached to the mesenteries are longitudinal bands of muscle (feathery areas). These retractor muscles contract to shorten the body and invert the tentacles (polyps) forcing water in and out of the body cavities. Magnification: x14 when printed at 10 centimetres high | |
