'''Cosmoledo Atoll''' is an [atoll](/source/atoll) of the [Aldabra Group](/source/Aldabra_Group) and belongs to the [Outer Islands](/source/Outer_Islands_(Seychelles)) of the [Seychelles](/source/Seychelles), and is located {{convert|1029|km|abbr=on}} southwest of the capital, [Victoria](/source/Victoria%2C_Seychelles), on [Mahé](/source/Mah%C3%A9%2C_Seychelles) Island.
==History==
The name ''Cosmoledo'' honours António (or Antão) Gonçalves Cosme Ledo who sailed to India in 1537 as pilot of the vessel ''Flor de la Mar'', becoming patron chief before returning to [Portugal](/source/Portugal) in 1545 aboard the ''São Joao''. [{{cite book |last1=Skerrett |first1=A. |title=Outer Islands of Seychelles |publisher=Camerapix |year=2018 |isbn=9781904722649}}]
Menai and Wizard Islands were named after ships that explored the atoll on the Moresby Expedition in 1822.
In 1878, Sergeant Rivers visited the atoll and reported that judging by the turtle remains on the beach, the atoll was frequently visited by fishermen and whalers. He found a recently destroyed hut and ‘turtle park’ on Menai; a hut on the southern point of Wizard built from the wreckage of the ''Merry Monarch'' (wrecked in April 1874), which had been burnt. He reported that Menai was virtually covered with tall mangroves. Cosmoledo was settled shortly after this and a visitor in 1895 noted 200-300 coconut trees, maize and goats. By 1901, there were just two men on Menai, one on Wizard and four on North-east Island. Exploitation of [guano](/source/guano) on North-east Island was taking place in 1901, when 120 tons had been removed. A few years later, mangrove bark had become an important product; it was dried and exported for tannin. The atoll was inhabited as a fishing and turtling station until 1992 when it was abandoned.
==Geography==
thumb|left|Cosmoledo Atoll and Astove Island
Cosmoledo Atoll is a [raised coral atoll](/source/raised_coral_atoll) that is 17 km long east–west, and 12.5 km north–south. The islands land area is 5.2 km2, and the [lagoon](/source/lagoon) and the reef flats have an area of 145 km2. The closest island is [Astove Island](/source/Astove_Island), 35 km farther south. The lagoon is up to 8.2 metres deep. Geologically, it is the twin of [Astove Island](/source/Astove_Island), standing on the same volcanic basement measuring 85 km from north to south and 52 km from east to west and rising from a depth of over 4 km. The two islands are sometimes known together as the Cosmoledo Group. The two peaks join at a depth of around 1 km. Unlike the steep wall of Astove, the sea floor falls gradually to about 50 metres over a distance of up to a kilometer then more steeply reaching 500 metres in about 1.5 km. Two main passes lead from the ocean to the shallow lagoon, one northwest of South Island and one (Grande Passe) between Pagoda Island and Wizard Island. On the western coast, elevated reef rock forms undercut headlands mirroring the waves of the sea and separated by sandy beaches. There are sand dunes in the north and south, rising to about 10 meters.
===List of islands===
The Constitution of Seychelles names 20 islands although there are also a number of unnamed islets in the atoll.

==Flora and fauna==
Cosmoledo is an [Important Bird Area](/source/Important_Bird_Area) and holds Seychelles' largest colonies of all three species of [booby](/source/booby) that breed in Seychelles.[[http://www.nation.sc/article.html?id=239893 News]] The atoll holds one of only two Seychelles populations of [brown booby](/source/brown_booby), breeding mainly on South Island, with a few on West-North Island. It also has the Indian Ocean's largest population of [red-footed booby](/source/red-footed_booby) censused by the [Island Conservation Society](/source/Island_Conservation_Society) as about 15,000 pairs.[Rocamora, G. Feare C.J., Skerrett, A., Athanase, M. and Greig, E. 2003. The breeding avifauna of Cosmoledo Atoll (Seychelles) with special reference to seabirds: conservation status and international importance. Bird Conservation International 13: 151-174.] Exploitation has wiped out the [lesser frigatebird](/source/lesser_frigatebird) and has almost done the same to the [great frigatebird](/source/great_frigatebird), which is down to just 15 pairs compared to hundreds of pairs in the 1970s. Despite this, hundreds of non-breeding frigatebirds of both species are to be seen, these being probably from [Aldabra](/source/Aldabra). The [lesser frigatebird](/source/lesser_frigatebird) also once bred but now may be extinct. Cosmoledo also has Seychelles' largest colony of [sooty tern](/source/sooty_tern) breeding on the northern end of Wizard Island. Second only to Aldabra are the numbers of breeding [red-tailed tropicbird](/source/red-tailed_tropicbird), [black-naped tern](/source/black-naped_tern) and [crested tern](/source/crested_tern). In May 2023, [Island Conservation Society](/source/Island_Conservation_Society) discovered [Caspian tern](/source/Caspian_tern) breeding on Menai, the second known oceanic breeding site in the world after [Aldabra](/source/Aldabra).
The lagoon is an important feeding ground for migratory waders, with [crab plover](/source/crab_plover) and [ruddy turnstone](/source/ruddy_turnstone) most common. There are three endemic races of land bird: the Madagascar white-eye (race ''menaiensis''), the [souimanga sunbird](/source/souimanga_sunbird) (race ''buchenorum'') and a particular form of [Madagascar turtle dove](/source/Madagascar_turtle_dove). The [Madagascar cisticola](/source/Madagascar_cisticola) is also common and there are a few [pied crow](/source/pied_crow) present.
The flora is similar to that of [Aldabra](/source/Aldabra), with fewer species but including several plants endemic to the group. As on Aldabra there are areas of tall mangrove, especially on the lagoon side of Menai Island. Coconuts are common only on Menai, where many were planted.
Lizards include Bouton's [snake-eyed skink](/source/snake-eyed_skink) and [Madagascar banded lizard](/source/Madagascar_banded_lizard), the latter found nowhere else in Seychelles. [Green turtle](/source/Green_turtle) nest in reasonably large numbers, despite decades of exploitation in the past and poaching in the present. The reefs are spectacular and offer some of the best diving in Seychelles.
The [Island Conservation Society](/source/Island_Conservation_Society) employs staff during the fishing season, conducting conservation and rehabilitation work on the atoll. Rats have been eradicated from all islands except Menai.[[http://www.seychellesnewsagency.com/articles/883/Seychelles+far+flung+atoll+of+Cosmoledo+to+get+airstrip IDC plans airport]][[http://www.nation.sc/article.html?id=247038 Arrest of poachers 2015]]
==Tourism==
There are fly-fishing cruises to the atoll on a regular basis.[[http://www.aardvarkmcleod.com/destination/cosmoledo-atoll Fly-fishing 1]]
The IDC have proposed a plan for an eco-resort with about 20 rooms to be built at Menai in 2019.[{{Cite web |url=http://seychellesinvest.com/uploads/presentations/Mr.ChristianLionnet-MluhRealEstateDevelopment.pdf |title=Future development |access-date=2016-04-09 |archive-url=https://web.archive.org/web/20160415220242/http://seychellesinvest.com/uploads/presentations/Mr.ChristianLionnet-MluhRealEstateDevelopment.pdf |archive-date=2016-04-15 |url-status=dead }}]
