Oral Disk of the Giant Green Anemone Anthopleura xanthogrammica

An intimate view of the monochromatic oral disk surface of A. xanthogrammica. The flat topography of the disk is interrupted by a large opening through which food passes and undigested material is expelled. Grains of sand dotting the disk surface are the remnants from a recent meal, or they’ve been deposited by the surf. The short conical tentacles surrounding the disk are characteristic of A. xanthogrammica.

In response to The Daily Post’s weekly photo challenge: “Monochromatic.”
