Physogyra lichtensteini is an endangered species that needs our help. There are many threats to the species such as coastal development, pollution and trade. These threats are all caused by human actions. In this article I will discuss the threats to Physogyra lichtensteini and how humans can possibly reverse the threats to the species. The common name of Physogyra lichtensteini is pearl bubble coral. Physogyra lichtensteini is an invertebrate, meaning it has no backbone and is part of the phylum Cnidaria. To fall into the phylum Cnidaria, the species must have stinging organelles, a mouth, and a basic digestive system. Physogyra lichtensteini lives in shallow tropical waters around the world. It is present in at least 83 countries. The Physogyra lichtensteini trade and destructive fishing practices have endangered already vulnerable species. It is legally permitted to harvest 11,000 specimens of pearl bubble coral per year, which has a negative impact on the species' dwindling numbers. In Indonesia alone, 10,500 pieces of live pearl coral were traded. To protect the species from extinction, countries should ban its collection and trade. In addition to the ban on pearl coral trade, countries should make further efforts to catch people who illegally harvest pearl coral and other endangered corals. Destructive fishing practices such as cyanide fishing endanger all corals. Fishermen spray cyanide in the space between the coral and on the fish to stun it. In doing so it creates a cloud of toxic chemicals that are poisonous to the organism around it. Another destructive fishing practice is also dynamite fishing......middle of paper......gyra lichtensteini we must do something to help. The trade in pearl coral must be banned and an effort should be made to catch those who illegally harvest endangered coral. Reckless fishing practices such as dynamite fishing and cyanide fishing should be banned in every country. Efforts should be made to prevent pollution, which is a major cause of the decline of Physogyra lichtensteini. The effects on water quality on marine life should be better studied and more efforts should be made to prevent water pollution from degrading the quality of ocean waters. Coastal development should be carefully monitored and the construction of buildings on or over coral reefs should be prohibited. Physogyra lichtensteini should be preserved for future generations. In conclusion, Physogyra lichtensteini needs our help and we should do everything necessary to ensure the survival of the species
