The incident was viral online following a Facebook post in July by Romina Lim, who found the 'exported' Tubipora and Heliopora
corals from the Philippines in a gift shop in Long Beach, Washington.
Heliopora coerulea is the only species in the subclass Octocorallia that has a crystalline aragonite skeleton.
The blue coral Heliopora coerulea (Pallas, 1766) is a "living fossil" species whose morphology differs slightly from that of the lower cretaceous Heliopora japonica (Eguchi, 1948).
The blue coral, Heliopora
coerulea (order Helioporacea), is one of the most dominant reef-building corals in the Bolinao Reef Complex, northern Philippines.
As summer sea surface temperatures have remained about 1.5 degrees Celsius above ambient over the last 10 years, growth of the coral, Diploastrea heliopora
, has declined by 30 per cent and "could cease growing altogether by 2070" or sooner, the researchers report in the journal Science.
The most significant feature of the reef is the presence of a blue coral, Heliopora
The most common corals harvested commercially in the past included Acropora, Antipathes, Fungia, Heliopora
, and Tubipora sp.
Genotype x environment interactions in transplanted clones of the massive corals Favia speciosa and Diploastrea heliopora
Only four species of octocoral were recorded in habitats under 6 m depth (Heliopora
coerulea, Lobophytum sp., and Anthelia sp., Sansibia sp.), whereas 28 species were recorded at a depth of 6 m to 14 m.
Massive Diploastrea heliopora
, which occurs throughout the Indo-Pacific, has relatively slow growth rates with linear extension rates of about 2-6 mm x [y.sup.-1] (Bagnato et al., 2004; Damassa et al., 2006; Cantin et al., 2010).

The blue pigment from the skeleton of the hydrocoral Heliopora
eaerulea has been identified as a calcium-bonded biliverdin, which belongs to the tetrapyrrole group of pigments (Tixier, 1945, cited in Fox and Wilkie, 1970).
