Ricordea florida
''Ricordea florida'' is a species of coral of the family Ricordeidae and the order Corallimorpharia, whose members are also called false corals. Due to their bright pigmentation, ''Ricordea florida'' is very popular in hobby saltwater aquariums.
==Morphology==
''Ricordea florida'' is a coral without a skeleton, having the same internal anatomical structure as corals of the order Scleractinia.
The body of the coral is small and cylindrical. The basal end resembles a flat disk that functions as a foot. The apical end is the oral disk which functions as one or more mouths. These mouths are centered amid short rounded tentacles bearing cnidoctios, whose sting contains paralytic neurotoxins. The sting is used to ingest prey more easily via the gastrovascular cavity, or as a defensive mechanism to evade enemies. The stinging ability of this species is lower than in most corals.
''Ricordea florida'' reaches 7.5 cm in diameter. The fleshy body and tentacles can be found in a variety of colours, including purple, orange, green, blue and yellow. The tips of the tentacles and the mouth may be one or more different colours. The colour of ''Ricordea florida'' depends on various factors, including the depth at which their live, temperature, season, and other environmental factors.
