The Hawaiian gold coral has a history of exploitation from the deep slopes and seamounts of the Hawaiian Islands as one of the precious corals commercialised in the jewellery industry. Due to its peculiar characteristic of building a scleroproteic skeleton, this zoanthid has been referred as Gerardia sp.

It hasPalau is world famous for its relatively pristine and highly diverse coral reefs, yet for many coral reef invertebrate taxa, few data exist on their diversity in this Micronesian country. One such taxon is the Zoantharia, an order of benthic cnidarians within the Class Anthozoa (Subclass Hexacorallia) that are commonly found in shallow subtropical and tropical waters. Here, we examine the ...The polyp is the basic living unit of Anthozoa (further subdivided into subclass Hexacorallia, which includes stony corals, and subclass Octocorallia, which includes soft corals). Polyps can occur either singularly, as in the case of anemones and some stony corals, or can form colonies, as they do in most stony and all soft corals.Within Anthozoa, the monophyly of Hexacorallia has low support due to the phylogenetic instability of Ceriantharia (Fig 4, S1 and S2 Figs), our most poorly sampled taxon within Anthozoa (16.6% gene sampling). Each analysis provides mixed support for the placement of Ceriantharia as either sister to the rest of the Hexacorallia, ...Jan 9, 2013 · The phylum Cnidaria encompasses five classes: Anthozoa, Cubozoa, Hydrozoa, Scyphozoa, and Staurozoa.

This includes skeletal structures composed of different calcium carbonate polymorphs (aragonite and calcite). This represents a unique feature among anthozoans, as scleractinian corals (subclass Hexacorallia), main reef builders and focus of biomineralization ...Abstract. Sea anemones (order Actiniaria) are among the most diverse and successful members of the anthozoan subclass Hexacorallia, being found at all depths and latitudes and in all marine habitats. Members of this group exhibit the greatest variation in anatomy, biology, and life history in Hexacorallia, and lack any morphological synapomorphy.Anthozoa is a class that consists of two subclasses, Hexacorallia (stony corals and sea anemones) and Octocorallia (soft corals and red corals). Medusozoa is a subphylum that consists of four classes, Hydrozoa (Hydra), Scyphozoa (true jellyfish), Cubozoa (box jellyfish), and Staurozoa (stalked jellyfish) (Technau and Steel, 2011)..
