Appearance
Fish-eating anemones have a smooth orange-red column with sturdy white tentacles, sometimes tipped with pink or red. The oral disc is red to pale orange and there are red markings at the base of each tentacle. The tentacles can reach a maximum length of nearly 14 inches. There are ~5 rows of sticky verrucae on the upper column. The disc is 8-10 inches wide and the column is up to 8 inches tall.
Habitat
Rocky bottoms from the low intertidal to depths of 160 feet, usually where there’s a current, often found in kelp forests
Diet
Fishes, shrimps, and other invertebrates
Life History
Fish-eating anemones can reproduce asexually by splitting.
They reproduce sexually by broadcasting spawning eggs or sperm in the water column. The planula larva is planktonic.
They can reach 12 inches tall and they live up to 80 years.
IUCN Status
Not Evaluated
Ecosystem & Cultural Importance
Juvenile painted greenlings will rest or swim among the tentacles of a fish-eating anemone at night. Predators include the leather star.
Though this anemone can’t swim, it is able to move. It will inflate itself, detach its base from the substrate, and allow the current to carry it. If a predator, like the leather star, touches a small or intermediate sized anemone (up to 5 inches), they may try to escape using this method. However, if a leather star tries to attack a larger fish-eating anemone, it might detach but then flip over onto the leather star and start to ingest it.
