[4] At greater depths, the substrate is too soft for the oysters to settle and the pressure from predators like crabs and fish is too extreme.
They consume a great range of organisms belonging to the following groups: Cyanobacteria, Xanthophyta, Bacillariophyta, Dinophyta, Euglenophyta, Chlorophyta, Protozoa, Rotifera, Annelida, Arthropoda, and Mollusca.
C. rhizophorae have also been shown to consume fragments of Phytoplankton, Zooplankton, and Phanerogamae and grains of sediment.
57% of the individuals were categorized as being in the full stage, which suggests the existence of good availability of food for C. rhizophorae in the environment that they are in.
[6] C. rhizophorae have primary bisexual gonads that form associations of cells in the connective tissue anterior to the heart by the time they reach 0.7 cm or 45 days after setting.
During this stage, the gametogenesis starts a new maturation that leads to the complete cytolysis of the gamete and obliteration of the follicles.
[4] Due to the constant high water temperature, gametogenesis happens twice during the year, March and October.
These peaks happen when drastic changes in salinity, rainy periods, but intense rains like 150 mm per week depress spawning.
C. rhizophorae tend to grow to 4 to 7 cm in length, and it can take up to 18 months for most members of the species to reach their full size.
C. rhizophorae grow best during the rainy season due to a higher influx of nutrients into estuarine areas.
[7] These platforms are typically made of branches of mangrove trees suspended from racks in the inter- and sub-tidal regions.
These allow for farmers to maintain populations of C. rhizophorae that meet consumer demands while preventing overfishing.
The artificial reefs of C. rhizophorae have also acted as nursery environments for many marine and estuarine species in the Caribbean.
