Mozambique • Cnidaria

The identifications were only made on the basis of the photographs which is very hazardous for most of the species. As a consequence the Latin names might not be accurate.
The books used for the identification are listed: bibliography.

This group is monophyletic, that's to say, you have a common ancestor and all its descendants. Nevertheless, it's a real nightmare. The use is to consider four classes:
Anthozoa: anemones, corals...
Hydrozoa: Portuguese Man o' War...
Scyphozoa: jellyfish
• Cubozoa: box jellies

Anthozoa are can be split in:
• Hexacorallia (6 way symmetry): Ceriantharia (tube anemones), Zoanthidea (zoanthids), Actiniaria (sea anemones), Corallimorpharia (coral anemones), Scleractinia (stony corals), Antipatharia (black corals), Zoanthidea (zoanthids)...
• Octocorallia (8 way symmetry): Alcyonacea (soft corals), Gorgonacea (sea fans), Helioporacea (blue coral), Pennatulacea (sea pens)...

I found this anemone very busy eating a Strombus gibberulus in shallow water. Any idea which species ?
