Anatomy of a zoanthid

The pedal disk is the bottom surface which attaches the zoanthid to substrate.
Stolons are the matting tissue connections between the polyps.
The column stretches from the oral disk to the pedal disk.
The Oral disk is the the flattened upper surface with the mouth in the center and tentacles around the margin.
The Mouth is the opening to the gut.
The tentacular crown is the ring of tentacles or skirt.
