Annika Lindqvist cc-by-nc-4.0

Acropora palmata (Elkhorn Coral) is a species of cnidarians in the family staghorn corals. They are listed as critically endangered by IUCN and in cites appendix ii. They are found in marine habitat. Elkhorn Coral form marine reefs. Dead Elkhorn Coral form shallow marine sediments. They have alternation of generations, asexual reproduction, and sexual reproduction; they are broadcast spawners and hermaphrodites. They are sessile animals.

URI: http://eol.org/schema/terms/criticallyEndangered
Definition: A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria A to E for Critically Endangered, and it is therefore considered to be facing an extremely high risk of extinction in the wild

URI: http://eol.org/schema/terms/CITES_II
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)

Definition: An aquatic biome that comprises systems of open-ocean and unprotected coastal habitats, characterized by exposure to wave action, tidal fluctuation, and ocean currents as well as systems that largely resemble these. Water in the marine biome is generally within the salinity range of seawater: 30 to 38 ppt.

- URI: http://eol.org/schema/terms/competitive
- Definition: Competitors are species that thrive in areas of low intensity stress and disturbance and excel in biological competition. These species are able to outcompete others by most efficiently tapping into available resources. Competitors do this through a combination of favorable characteristics, including rapid growth rate, high productivity and high capacity for phenotypic plasticity.
