Sea Anemone Classification
Sea Anemones are classified as follows:
- Phylum Cnidaria (which means stinging nettle) also known as Phylum Coelenterata (which means hollow gut)
- Class Anthozoa (which means flower animal)
- Order Actiniaria (which means with rays)
In general, sea anemones are classified according to appearance and habitat although some experts also consider such features as the size and distribution of nematocysts, and arrangement of tentacles in relation to their internal anatomy to be important.
Sea anemones don't have any hard body parts that will easily fossilize but a few fossils do exist. The oldest identified fossil sea anemone is reported to date back to the Middle Cambrian, over 500 million years ago.
