| Although the two species were not found in sympatry, a population of P. elegans was found only 9 km away from a P. actinia population in Santo Antonio da Patrulha county. |
| One of the most common among the many varieties of sea-anemones is the actinia mesembryanthemum. |
| Genetic materials inserted into the cactus and responsible for luminescence are GFP-like proteins taken from the Pacific actinia known as Anemonia Sulcata. |
| The locomotive power of the anemone, or actinia, is very sluggish. |
| Cut off the tentacles of an actinia, and they are replaced in a short time, and the experiment may be repeated indefinitely. |
| This actinia differs from those described above, in having two of the sides flattened, instead of being perfectly circular. |
