In Hawai‘i, the Carijoa species was identified as C. riisei by a leading octocoral taxonomist. However, recent molecular sequencing work in progress is now casting doubt on the Caribbean/Atlantic origin for the Hawai‘ian population (Samuel Kahng., pers. comm., 2005).

C. riisei is a voracious feeder and can consume large quantities of zooplankton (ecological impacts of this feeding habit are yet to be studied) (Kahng, Undated(b)). C. riisei exhibits high fecundity compared to other corals (clonal benthic marine invertebrates like corals in general exhibit much lower fecundity than aclonal benthic marine invertebrates like mussels). No significant predators have of C. riisei have been found in Hawai‘i with the possible exception of a recently discovered introduced nudibranch, Phyllodesmium poindimiei. Predators of Carijoa in other parts of the globe have been reported (Samuel Kahng., pers. comm., 2005).
\r\nBiological: Kahng (Undated(a)) has found that, \"A potential agent of C. riisei bio-control (introduced aeolid nudibranch soft coral predator) has recently been identified but must undergo further research before it can be considered as an actual management technique.\"
