Ricordea florida is found in the interior of reefs, usually in shallow water, rocky areas, and pools. The colour of Ricordea florida depends on various factors, including the depth at which they live, the temperature, the season, and other environmental factors. The tips of the tentacles and the mouth may be one or more different colours. The fleshy body and tentacles can be found in a variety of colours, including purple, orange, green, blue and yellow. Ricordea florida reaches 7.5 cm in diameter. The stinging ability of this species is lower than in most corals. The sting is used to subdue prey to make it more easily ingested via the mouth, or as a defensive mechanism to evade enemies. These mouths are centered amid short rounded tentacles bearing cnidocytes, whose sting contains paralytic neurotoxins. The apical end is the oral disk which functions as one or more mouths. The basal end resembles a flat disk that functions as a foot. The body of the coral is small and cylindrical.

This may be why they are able to quickly overtake sections of substrate and become the dominant coral species after a disturbance. They have been observed asexually reproducing through marginal budding, a process where sections of the margin of the coral's oral disk, including tentacles and a replicated mouth, elongate and detach from the mother coral. Ricordea yuma are capable of both sexual and asexual reproduction. Stressors like reef degradation and disturbance and raised nutrient load influence Corallimorpharian growth Raised nutrient load may favor the competitive success of Corallimorpharians including Ricordea yuma, when competing with reef-building corals. ![]() Corallimorpharians, including Ricordea yuma, can prevent reef-building corals from settling by competitively excluding them. They live in shallow water, settling on benthic substrate. ![]() In a study of coral reef degradation in the Indian Ocean, it was noted that they are mostly distributed on the reef flat. ![]() Ricordea yuma are a tropical species, found in Indo-Pacific environments. They also acquire nutrients by living in close association with Zooxanthelle, a symbiotic dinoflagellate. ![]() The diet of Ricordea yuma includes echinoderms, crustaceans, small fishes, and zooplankton. It is unknown what causes this, but hypotheses include an unknown pathogen, or moving from natural to artificial lighting. Ricordea yuma can be affected by “melting syndrome”, where the coral loses its shape and tentacles and appears to melt over the course of many days. They also lack skeletons, Corallimorpharia can range in size from a few centimeters up to a meter in diameter Ricordea yuma falls in this range, but may have narrower size constraints. Like most Corallimorpharia, Ricordea yuma are very colorful. The oral disk connects ventrally to a thin body, with a foot disk at its end. Ricordea yuma have a large oral disk, covered in tentacles that spread out from the center in a spiral formation. Phylogenomic analysis has shown that they are not descendants of scleractinian corals that lost their ability to calcify, but are rather a sister clade Throughout their evolution Corallimorpharia never had the ability to calcify, making the label “naked corals” somewhat of a misnomer. Ricordea yuma is a corallimorpharian species, often called “naked” or “false” corals because they lack the distinctive calcification of related scleractinian corals.
