{{See also|Eastern Arabia|Arab states of the Persian Gulf}}This inland sea of some {{convert|251000|km²|0|abbr=out}} is connected to the Gulf of Oman in the east by the Strait of Hormuz; and its western end is marked by the major river delta of the Shatt al-Arab, which carries the waters of the Euphrates and the Tigris. In Iran this is called "Arvand Rood", where "Rood" means "river". Its length is {{convert|989|km|0|abbr=off}}, with Iran covering most of the northern coast and Saudi Arabia most of the southern coast. The Persian Gulf is about {{convert|56|km|0|abbr=on}} wide at its narrowest, in the Strait of Hormuz. The waters are overall very shallow, with a maximum depth of {{convert|90|m|0|abbr=off}} and an average depth of {{convert|50|m|0|abbr=off}}.Countries with a coastline on the Persian Gulf are (clockwise, from the north): Iran; Oman's Musandam exclave; the United Arab Emirates; Saudi Arabia Qatar, on a peninsula off the Saudi coast; Bahrain, on an island; Kuwait; and Iraq in the northwest. Various small islands also lie within the Persian Gulf, some of which are the subject of territorial disputes between the states of the region.


The International Hydrographic Organization defines the Persian Gulf's southern limit as "The Northwestern limit of Gulf of Oman". This limit is defined as "A line joining Ràs Limah (25°57'N) on the coast of Arabia and Ràs al Kuh (25°48'N) on the coast of Iran (Persia)".


The gulf is connected to Indian Ocean through Strait of Hormuz. Writing the water balance budget for the Persian Gulf, the inputs are river discharges from Iran and Iraq (estimated to be 2000 cubic meters per second), as well as precipitation over the sea which is around 180mm/year in Qeshm Island. The evaporation of the sea is high, so that after considering river discharge and rain contributions, there is still a deficit of 416 cubic kilometers per year.JOURNAL, Pous, Stéphane, Lazure, Pascal, Carton, Xavier, A model of the general circulation in the Persian Gulf and in the Strait of Hormuz: Intraseasonal to interannual variability,weblink Continental Shelf Research, 94, 55–70, 10.1016/j.csr.2014.12.008, 2015, This difference is supplied by currents at the Strait of Hormuz.

Another study revealed the following numbers for water exchanges for the Gulf: evaporation = -1.84m/year, precipitation = 0.08m/year, inflow from the Strait = 33.66m/year, outflow from the Strait = -32.11m/year, and the balance is 0m/year.JOURNAL, Xue, Pengfei, Eltahir, Elfatih A.

From among the writings of others in the same period, there is the inscription and engraving of Darius the Great, installed at junction of waters of Red Sea and the Nile river and the Rome river (current Mediterranean) which belongs to the 5th century BC where Darius the Great has named the Persian Gulf Water Channel: "Pars Sea" ("Persian Sea").Considering the historical background of the name Persian Gulf, Sir Arnold Wilson mentions in a book published in 1928 that "no water channel has been so significant as Persian Gulf to the geologists, archaeologists, geographers, merchants, politicians, excursionists, and scholars whether in past or in present. This water channel which separates the Iran Plateau from the Arabia Plate, has enjoyed an Iranian Identity since at least 2200 years ago."Before being given its present name, the Persian Gulf was called many different names. The classical Greek writers, like Herodotus, called it "the Red Sea". In Babylonian texts, it was known as "the sea above Akkad".{{citation needed|date=December 2016}}

The shallow basin that now underlies the Gulf was an extensive region of river valley and wetlands during the transition between the end of the Last Glacial Maximum and the start of the Holocene, which, according to University of Birmingham archaeologist Jeffrey Rose, served as an environmental refuge for early humans during periodic hyperarid climate oscillations, laying the foundations for the legend of Dilmun.JOURNAL, New Light on Human Prehistory in the Arabo-Persian Gulf Oasis, Current Anthropology, December 2010, Rose, Jeffrey I., 51, 6, 849–883, 10.1086/657397, 2016-11-19, For most of the early history of the settlements in the Persian Gulf, the southern shores were ruled by a series of nomadic tribes. During the end of the fourth millennium BC, the southern part of the Persian Gulf was dominated by the Dilmun civilization. For a long time the most important settlement on the southern coast of the Persian Gulf was Gerrha. In the 2nd century the Lakhum tribe, who lived in what is now Yemen, migrated north and founded the Lakhmid Kingdom along the southern coast. Occasional ancient battles took place along the Persian Gulf coastlines, between the Sassanid Persian empire and the Lakhmid Kingdom, the most prominent of which was the invasion led by Shapur II against the Lakhmids, leading to Lakhmids' defeat, and advancement into Arabia, along the southern shore lines.BOOK,weblink E.J.

One of the more unusual marine mammals living in the Persian Gulf is the dugong (Dugong dugon). Also called "sea cows", for their grazing habits and mild manner resembling livestock, dugongs have a life expectancy similar to that of humans and they can grow up to {{convert|3|m|abbr=off}} in length. These gentle mammals feed on sea grass and are closer relatives of certain land mammals than are dolphins and whales.WEB,weblink Case Study,, 2009-07-10, yes,weblink" title="">weblink June 24, 2009, Their simple grass diet is negatively affected by new developments along the Persian Gulf coastline, particularly the construction of artificial islands by Arab states and pollution from oil spills caused during the "Persian Gulf war" and various other natural and artificial causes. Uncontrolled hunting has also had a negative impact on the survival of dugongs. After Australian waters, which are estimated to contain some 80,000 dugong inhabitants, the waters off Qatar, Bahrain, UAE, and Saudi Arabia make the Persian Gulf the second most important habitat for the species, hosting some 7,500 remaining dugongs. However, the current number of dugongs is dwindling and it is not clear how many are currently alive or what their reproductive trend is.WEB,weblink Persian Gulf Mermaids Face Environmental Threats, Maurice Picow, 2010-03-04, 2010-11-19, Unfortunately, ambitious and uncalculated construction schemes, political unrest, ever-present international conflict, the most lucrative world supply of oil, and the lack of cooperation between Arab states and Iran, have had a negative impact on the survival of many marine species, including dugongs.


The Persian Gulf is also home to many migratory and local birds. There is great variation in color, size, and type of the bird species that call the gulf home. Concerns regarding the endangerment of the kalbaensis subspecies of the collared kingfishers were raised by conservationists due to real state development by the United Arab Emirates and Oman. Estimates from 2006 showed that only three viable nesting sites were available for this ancient bird, one located {{convert|80|mi|0|abbr=out}} from Dubai, and two smaller sites in Oman. Such real estate expansion could prove devastating to this subspecies. A UN plan to protect the mangroves as a biological reserve was ignored by the emirate of Sharjah, which allowed the dredging of a channel that bisects the wetland and construction of an adjacent concrete walkway. Environmental watchdogs in Arabia are few, and those that do advocate the wildlife are often silenced or ignored by developers of real estate many of whom have governmental connections. Real estate development in the Persian Gulf by the United Arab Emirates and Oman also raised concerns that habitats of species such as the hawksbill turtle, greater flamingo, and booted warbler may be destroyed.WEB,weblink Turtles Rehabilitated After Persian Gulf Oil Spills, Tim Thomas, Ian Robinson, yes, 2001, 2010-11-23, The dolphins that frequent the gulf in northern waters around Iran are also at risk. Recent statistics and observations show that dolphins are at danger of entrapment in purse seine fishing nets and exposure to chemical pollutants; perhaps the most alarming sign is the "mass suicides" committed by dolphins off Iran's Hormozgan province, which are not well understood, but are suspected to be linked with a deteriorating marine environment from water pollution from oil, sewage, and industrial run offs.WEB, Dolphins of Persian Gulf are in danger, Mandana Javidinejad, Payvand News Agency, 2007, December 25, 2010,weblink WEB, Iran: Spill, Dolphin Deaths Spark Alarm At Persian Gulf Pollution, Vahid Sepehri, Radio Free Europe, Radio Liberty, October 3, 2007, December 25, 2010,weblink

Fish and reefs

The Persian Gulf is home to over 700 species of fish, most of which are native.WEB,weblink Fish Species in Persian Gulf, Jen/, 2003-06-30, 2010-11-24, Of these 700 species, more than 80% are reef associated. These reefs are primarily rocky, but there are also a few coral reefs. Compared to the Red Sea, the coral reefs in the Persian Gulf are relatively few and far between.BOOK, Debelius, H., Indian Ocean Tropical Fish Guide, 1993, Aquaprint Verlag GmbH, 5, 3-927991-01-5, JOURNAL, Emery K.O., Sediments and water of the Persian Gulf, 1956, Bull AAPG, 401, 2354–2383, 10.1038/srep04250, 3945051, 24603901, JOURNAL, Pohl; Al-Muqdadi; Ali; Fawzi; Ehrlich; and Merkel, Discovery of a living coral reef in the coastal waters of Iraq, 2014, Sci. Rep., 4, 4250, 10.1038/srep04250, 3945051, 24603901, This is primarily connected to the influx of major rivers, especially the Shatt al-Arab (Euphrates and Tigris), which carry large amounts of sediment (most reef-building corals require strong light) and causes relatively large variations in temperature and salinity (corals in general are poorly suited to large variations). Nevertheless, coral reefs have been found along sections of coast of all countries in the Gulf. Corals are vital ecosystems that support multitude of marine species, and whose health directly reflects the health of the gulf. Recent years have seen a drastic decline in the coral population in the gulf, partially owing to global warming but majorly due to irresponsible dumping by Arab states like the UAE and Bahrain.WEB,weblink Dumping by Construction Crews Killing Bahrain Coral, Maurice Picow, 2010-06-16, 2010-11-19, Construction garbage such as tires, cement, and chemical by products have found their way to the Persian Gulf in recent years. Aside from direct damage to the coral, the construction waste creates "traps" for marine life in which they are trapped and die. The end result has been a dwindling population of the coral, and as a result a decrease in number of species that rely on the corals for their survival.


A great example of this symbiosis are the mangroves in the gulf, which require tidal flow and a combination of fresh and salt water for growth, and act as nurseries for many crabs, small fish, and insects; these fish and insects are the source of food for many of the marine birds that feed on them.WEB,weblink Development in Persian Gulf Threatens Wildlife, 2008-06-30, Jim Krane, July 3, 2006, Discovery Channel, yes,weblink" title="">weblink 2006-09-23, Mangroves are a diverse group of shrubs and trees belonging to the genus Avicennia or Rhizophora that flourish in the salt water shallows of the gulf, and are the most important habitats for small crustaceans that dwell in them. They are as crucial an indicator of biological health on the surface of the water, as the corals are to biological health of the gulf in deeper waters. Mangroves' ability to survive the salt water through intricate molecular mechanisms, their unique reproductive cycle, and their ability to grow in the most oxygen-deprived waters have allowed them extensive growth in hostile areas of the gulf.WEB,weblink Mangals, SunySB, 2010-11-23, JOURNAL, Expression of mangrove allene oxide cyclase enhances salt tolerance in Escherichia coli, yeast, and tobacco cells, Plant and Cell Physiology, Fall 1980, Yamada, Akiyo, Saitoh, Takeo, Mimura, Tetsuro, Ozeki, Yoshihiro, 43, 8, 903–910, 10.1093/pcp/pcf108,weblink However, with the advent of artificial island development, most of their habitat is destroyed, or occupied by man-made structures. This has had a negative impact on the crustaceans that rely on the mangrove, and in turn on the species that feed on them.
