“…This soft coral settles on a broad variety of habitats, often found associated with fouling communities, coral reefs, mangroves, outside harbors on shipwrecks, or in sheltered crevices in turbid waters rich with organic matter (Sánchez 1994). This species has been mainly recorded in shallow waters, but it can be found at depths of up to 95 m (Bayer 1959;Castro et al 2010). It is a non-photosynthetic coral that feeds on zooplankton and organic particles, which requires moderate amounts of water flow by wave surge, tidal currents, or long-shore currents (Carlton and Eldredge 2009;Lira et al 2009;Barbosa et al 2014;Friedlander et al 2014).…”

One colony of the snowflake coral Carijoa riisei (Alcyonacea: Clavulariidae) was found in June 2016, and three more in January 2017, during dives in the port of Manzanillo, Colima, Mexico (Tropical Eastern Pacific). This species was considered as native to the tropical Western Atlantic and invasive in the Pacific, but recent studies suggest that it is native to the Indo-West Pacific. Colonies were found and collected from artificial substrates in the port. A total of 29 species of invertebrates of five different phyla were associated with the colonies of C. riisei. Moreover, the octocoral was found as an epibiont on the architect crab Pelia tumida. Our observations suggest that the invasion of C. riisei in Manzanillo is in an early stage and that on-going monitoring and implementation of an eradication plan is necessary before its distribution is increased.

“…[11] In contrast, P. dilatata is leaf-like gorgonian with color ranging from white, cream, to pale yellow. [12] However, violet/purple coloration has also been associated with colonies with tissue damage. [12] A similar phenomenon was previously reported for the Caribbean gorgonian Gorgonia spp., in which a circumscribed purple halo resulting from an increase of purple sclerites surrounding the necrotic tissues is thought as due to Aspergillus sydowii infection, physical interaction with macroalgae and with the hydrozoan Millepora alcicornis, and predation by Cyphoma gibbosum.…”

Phyllogorgia dilatata is a Brazilian endemic gorgonian with a natural color ranging from white to pale yellow. An unusual violet pigmentation has been observed in colonies with tissue damage and skeleton anomalies. In order to investigate the chemical composition of these pigments, we have used in situ Raman spectroscopy to characterize the white/cream and violet tissues as well as sclerites, a skeletal component consisting of calcite, from both samples. Violet/purple pigmentation surrounding tissue necrosis is characterized as purpling, in response to fungus infection and allelopathic interactions. The spectroscopic analysis of the white-cream tissues, designated as healthy, has revealed the presence of the carotenoid peridinin, typical of the endosymbiont that harbors this species; however, peridinin was not observed in the colorless sclerites analysis, presenting bands exclusively of calcite. In contrast, the violet coloration of damaged tissue has also been observed in the sclerites. Both showed Raman bands corresponding to unmethylated polyunsaturated aldehyde, besides calcite bands. This is the first report of purpling in a Brazilian octocoral, identified as a derivative of the biochromes named psittacofulvins, which have been reported as exclusive in parrots.

“…There are approximately 3000 species of extant octocorals known worldwide (Daly et al 2007), yet only over 100 species and/or morphotypes have been recorded in Brazil (Castro et al 2010). Most of the records for this country date back to the late 19th to early 20th centuries; thus, few related data are available in journals, but there are abundant records in grey literature such as in MSc and PhD dissertations (Castro et al 2010).…”
