acanthestrea+brevis

1.acanthestrea brevis 2.kingdom: animalia phylum: cnidaria class: anthazoa order: scleractinia family: mussidae genus: acanthastrea 3.Endangered.This species is widespread and uncommon throughout its range. It is particularly susceptible to Crown of thorns starfish predation, and extensive reduction of coral reef habitat due to a combination of threats. Specific population trends are unknown but population reduction can be inferred from declines in habitat quality based on the combined estimates of both destroyed reefs and reefs at the critical stage of degradation within its range. Its threat susceptibility increases the likelihood of being lost within one generation in the future from reefs at a critical stage. Estimated habitat degradation and loss of 36% over three generation lengths 30 years is the best inference of population reduction and meets the threshold for Vulnerable under Criterion A4ce. It is important to reassess this species in 10 years time because of predicted threats from climate change and ocean acidification. 4.This species is found in all reef habitats at depths of 1-20 m. 5.In the Indo-West Pacific, this species is found in the Red Sea and Gulf of Aden, SW Indian Ocean, Northern Indian Ocean, Central Indo-Pacific, Oceanic West Pacific. It is also found in the Great Barrier Reef and American Samoa and Fiji 6.marine fishing areas- indian Ocean – western; Indian Ocean – eastern; Pacific – eastern central; Pacific – northwest; Pacific – western central 7.Most Tempature range is 75.2f to 82.4f. Average to high salinity, poor to average visibility due to high sedimentation levels.

8. Migration.Found to be locally abundant, Migartion of new propagules from neighbouring atolls 9.Population.There is no species specific population information available for this species.There is eveidence that overall coral reef habitat has declined and this is used as a proxy for population decline for this species. 10.Survival.Reef losses throughout the species range have been estimated over three generations,two in the past and one inthe future. 11.Appearence.Size varies,colors are red,blue,cream,green,orange and yellow. 12.Reproduction.Relying on indeterminate growth,asexual reoduction can take many forms.Budding transversal and longitudinal fission are some typical methods.Fertility is in the form of colonies or polyps. 13.Anatomy. Coral is a polyp.The polyps are sac like with radial symmertry. On the bottom side they have anchoring or basal disk which is used anchor the polyp, Coral only have one orifice serving as mouth and anus.There soft bodies live inside a tube or create a erect stucture,rigid,semi rigid or soft which anchor there polyps. 14.Food.Coral feed on plankton and microscopic algae. 15.Threats and Pollution. Are Crown of Throns starfish are vorscious predators of reef building corals the major threat is global climate change leading to bleaching and increased susceptibilty to disaese. Fisheries,dynamite fishing and chenical fishing are all threats.Dirty water is not a problem for some coral and deadly for others. Our life styles,industry,settlement,tourism and transpotation are some causes for pollution too. 16.Conservation. All corals are listed on CITES appendix II. Parts of the species range fall within Marine Protected areas.Recommended measures for conserving include research taxonomy,population,abundance and trends,ecology and habitat status threats and resilience to threats are some.Artifical propagation and tehniques such as cryo preservation of gametes may become important for conserving coral biodiversity. 17. Solutions.Have more restrictions on fishing industry,create more fish pods and fish farming to protect the corals from the elemntes that go in to open waters for fisherman. Industries should give a portion of there profits to keep the sea enviorment clean. Tourism and transport tation should be limited from certainn areas were reefs and coral thrive.
