A group of
Diadumene lineata in the mud at low tide in San Francisco Bay. These anemones are attached to rocks or debris below the mud surface. When the tide comes in, they poke up through the mud and extend their tentacles to feed.

Diadumene lineata (Verrill, 1870)
ORANGE-STRIPED GREEN ANEMONE
Diadumene lineata is a small anemone, growing to a maximum height of 3 cm. It has a smooth, cylindrical column that is usually olive-green or greenish-brown, but can also be gray-green or bright green. Often there are single or double orange, yellow, white or gray vertical stripes on the column, though some specimens are stripeless. The interior of the column is partitioned into spaces by thin walls of tissue, and the outer edges of these partitions where they attach to the column sometimes show through on the outside as thin vertical lines.
