Lesser Knob Coral

Cyphastrea chalcidicum (Forskål 1775)

Cyphastrea chalcidicum (Lesser Knob Coral) is a species of cnidarians in the family Merulinidae. It has a crustose growth form. It is listed in CITES Appendix II. Lesser Knob Coral form marine reefs. It is a photosymbiotroph. It has alternation of generations, asexual reproduction, and sexual reproduction; it is a broadcast spawner and a hermaphrodite. Lesser Knob Coral is a sessile animal.

Definition: Appendix II lists species that are not necessarily now threatened with extinction but that may become so unless trade is closely controlled. It also includes so-called "look-alike species", i.e. species whose specimens in trade look like those of species listed for conservation reasons. International trade in specimens of Appendix-II species may be authorized by the granting of an export permit or re-export certificate. No import permit is necessary for these species under CITES (although a permit is needed in some countries that have taken stricter measures than CITES requires). Permits or certificates should only be granted if the relevant authorities are satisfied that certain conditions are met, above all that trade will not be detrimental to the survival of the species in the wild. (See Article IV of the Convention)

EOL has data for 39 attributes, including:

abundance
- URI: http://purl.obolibrary.org/obo/NCIT_C70589
- Definition: Relative degree of plentifulness.

common
- URI: https://www.wikidata.org/entity/Q5153621
- Definition: Common species and uncommon species are designations used in ecology to describe the population status of a species. Commonness is closely related to abundance. Abundance refers to the frequency with which a species is found in controlled samples; in contrast, species are defined as common or uncommon based on their overall presence in the environment. A species may be locally abundant without being common.

adaptive strategy

stress-tolerant
- URI: http://eol.org/schema/terms/stressTolerant
- Definition: Stress tolerant species live in areas of high intensity stress and low intensity disturbance. Species that have adapted this strategy generally have slow growth rates, high rates of nutrient retention, and low phenotypic plasticity. Stress tolerators respond to environmental stresses through physiological variability. These species are often found in stressful environments.

- Definition: Diameter of the egg life stage of this organism. An egg is an organic vessel in which an embryo first begins to develop. In most birds, reptiles, insects, molluscs, fish, and monotremes, it is the zygote, resulting from fertilization of the ovum, which is expelled from the body and permitted to develop outside the body until the developing embryo can survive on its own.
