This Aulactinia incubans (Warty columned anemone) is partly covered by a piece of barnacle shell. The tide was coming in so I couldn't get a better photo.
This beautiful Epiactis lisbethae (Brooding Anemone) was hanging upside down under a rock during the minus tide.
Anthozoa is a class within the phylum Cnidaria. Unlike other cnidarians, anthozoans do not have a medusa stage in their development. Instead, they release sperm and eggs that form a planula, which attaches to some substrate on which the cnidarian grows. Some anthozoans can also reproduce asexually through budding. More than 6,100 species have been described.
