Coral Anemones, False Corals, Mushrooms: Order Corallimorpharia; part 1

To: part 2, part 3

By Bob Fenner

Two Amplexidiscus in captivity

Coral anemones, mushroom anemones or false corals are perhaps the most celebratedly hardy "corals"; often reproducing readily in well-kept systems. They have much to their merit besides, being relatively inexpensive and available in reds, blues, greens, purples and variegated patterns. Corallimorpharians require little specialized care as you will see.

Classification: Taxonomy, Problems, Relation With Other Groups

Coral anemones are closely related to the stony or true corals, indeed they are sometimes grouped as part of the same Order (Scleractinia) as a sub-order. One arrangement:

Phylum Cnidaria: Phylum Cnidaria: Stinging-celled animals. Anemones, corals, sea fans, jellyfishes, sea pens... Polyps and/or medusae stages

Class Anthozoa: Class Anthozoa: Polyp stage only, stomach divided in numerous compartments.

Sub-Class Zoantharia (Hexacorallia): More than eight and multiples of six tentacles.

Order Corallimorpharia: Coral anemones. Solitary or colonial, flattened mushroom-like anemones. Short, stubby tentacles radially arranged. Look like true corals, but lack skeletons. About ten families. Most common genera Actinodiscus, Ricordea, Corynactis, Rhodactis, Amplexidiscus. (the last two can eat unwary fishes... commonly clowns) Individual polyps 1 inch to 1 foot across.

Stippled, smooth, to fuzzy and striped, the most common Corallimorphs comprise the genus Discosoma/"Actinodiscus"
