Bunodosoma californicum is a species of sea anemone.It was first described to science by Oskar Carlgren in 1951. [1] The type specimen that Carlgren used to describe the species was collected by Ed Ricketts in Puerto Escondido during his trip to the Gulf of California with John Steinbeck recounted in The Log From the Sea of Cortez.
Sea anemones do not fossilize well, having no hard parts, and this one was mistakenly identified as a sea cucumber. Most Actiniaria do not form hard parts that can be recognized as fossils, but a few fossils of sea anemones do exist; Mackenzia , from the Middle Cambrian Burgess Shale of Canada, is the oldest fossil identified as a sea anemone.
Corynactis californica is a brightly colored colonial anthozoan corallimorph.Unlike the Atlantic true sea anemone, Actinia fragacea, that bears the same common name, strawberry anemone, this species is a member of the order Corallimorpharia, and is the only member found on the west coast of North America.

A cnidocyte (also known as a cnidoblast) is an explosive cell containing one large secretory organelle called a cnidocyst (also known as a cnida (pl.: cnidae)) that can deliver a sting to other organisms. The presence of this cell defines the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.). Cnidae are used to capture prey and as ...
Bennett had stumbled on a rare and “highly venomous” species of sea anemone: Dofleinia armata, also known as the armed anemone or striped anemone, she wrote in a Feb. 11 Facebook post.
Some amphipods live inside the coelenteron of the sea anemone. [31] Despite their venomous cells, sea anemones are eaten by fish, starfish, worms, sea spiders and molluscs. The sea slug Aeolidia papillosa feeds on the aggregating anemone (Anthopleura elegantissima), accumulating the nematocysts for its own protection. [31]
A study released in June 2021 found that these large anemones consume land-dwelling insects and ostracods. [7] Large anemones have few predators but smaller specimens are eaten by the sea stars, Pisaster spp., and by various nudibranchs. The starfish, Dermasterias imbricata, has been observed feeding on larger anemones in Puget Sound. [6] [8]
Invertebrate sea life includes the following groups, some of which are phyla: The 49th plate from Ernst Haeckel's Kunstformen der Natur, 1904, showing various sea anemones classified as Actiniae, in the Cnidaria phylum "A variety of marine worms": plate from Das Meer by M.J. Schleiden (1804–1881) Acoela, among the most primitive bilateral ...
