The blue coral (Heliopora coerulea), the only extant species in the family Helioporidae, is most common in shallow water of the tropical Pacific [6] and Indo-Pacific reefs. [7] It has no spicules , and is the only octocoral known to produce a massive skeleton formed of fibrocrystalline aragonite fused into lamellae , similar to that of the ...
Blue coral (Heliopora coerulea) is a species of colonial coral. It is the only octocoral known to produce a massive skeleton. [3] This skeleton is formed of aragonite, similar to that of scleractinia. Individual polyps live in tubes within the skeleton and are connected by a thin layer of tissue over the outside of the skeleton.
Pacific sea nettles, Chrysaora fuscescens. Cnidaria (/ n ɪ ˈ d ɛər i ə, n aɪ-/ nih-DAIR-ee-ə, NY-) [4] is a phylum under kingdom Animalia containing over 11,000 species [5] of aquatic invertebrates found both in fresh water and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites.
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 ...
