Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates throughout the world. They range from 1.6 to 60 centimetres.
The geography of New Caledonia (Nouvelle-Calédonie), an overseas collectivity of France located in the subregion of Melanesia, makes the continental island group unique in the southwest Pacific. Among other things, the island chain has played a role in preserving unique biological lineages from the Mesozoic. It served as a waystation in the expansion of the predecessors of the Polynesians, the Lapita culture. Under the Free French it was a vital naval base for Allied Forces during the War in the Pacific.
The gargoyle gecko, knob-headed giant gecko, New Caledonia bumpy gecko, or New Caledonian bumpy gecko is a species of gecko found only on the southern end of the island of New Caledonia. Its habitat is threatened by deforestation on the island. This species of gecko is the smallest of the six recognized species in its genus where they often reach about 125 mm in size. This gecko, along with several other Rhacodactylus species are being considered for protective measures by CITES, which would put restrictions on their exportation. This gecko was first described by Bavay in 1869.
The crested gecko, also known commonly as the eyelash gecko, is a species of lizard in the family Diplodactylidae. The species is native to southern New Caledonia. In 1866, the crested gecko was originally described by French zoologist Alphonse Guichenot. The species was thought to be extinct until it was rediscovered in 1994 during an expedition led by German herpetologist Robert Seipp. Along with several other New Caledonian gecko species, it is being considered for protected status by the Convention on the International Trade in Endangered Species of Wild Flora and Fauna.
Mniarogekko chahoua, commonly known as the mossy New Caledonian gecko, short-snouted New Caledonian gecko, Bavay's giant gecko, or mossy prehensile-tailed gecko, is an arboreal gecko found natively on the southern portion of the island of New Caledonia and on the outlying islands of Île des Pins.
Correlophus sarasinorum, also called commonly Roux's giant gecko, Sarasins' giant gecko, Sarasin's [sic] giant gecko (incorrectly), and the suras gecko, is a species of lizard in the family Diplodactylidae. The species is native to the southern portions of the outlying New Caledonian island of Grande Terre.
The rough-snouted giant gecko, also known as the greater rough-snouted gecko or tough-snouted gecko, is a species of gecko found in New Caledonia.
The leopard gecko or common leopard gecko is a ground-dwelling gecko native to the rocky dry grassland and desert regions of Afghanistan, Iran, Pakistan, India, and Nepal. The leopard gecko is a popular pet, and due to extensive captive breeding it is sometimes referred to as the first domesticated species of lizard.
The biodiversity of New Caledonia is of exceptional biological and paleoecological interest. It is frequently referred to as a biodiversity hotspot. The country is a large South Pacific archipelago with a total land area of more than 18,000 square kilometres (6,900 sq mi). The terrain includes a variety of reefs, atolls, small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. The region's climate is oceanic and tropical.
The Isle of Pines is an island in the Pacific Ocean, in the archipelago of New Caledonia, an overseas collectivity of France. The island is part of the commune (municipality) of L'Île-des-Pins, in the South Province of New Caledonia. The Isle of Pines is nicknamed l'île la plus proche du paradis.
The tokay gecko is a nocturnal arboreal gecko in the genus Gekko, the true geckos. It is native to Asia and some Pacific Islands.
Paicî is the most widely spoken of the two dozen languages on the main island of New Caledonia. It is spoken in a band across the center of the island, in the communes of Poindimié, Ponérihouen, Koné and Poya.
Island gigantism, or insular gigantism, is a biological phenomenon in which the size of an animal species isolated on an island increases dramatically in comparison to its mainland relatives. Island gigantism is one aspect of the more general "island effect" or "Foster's rule", which posits that when mainland animals colonize islands, small species tend to evolve larger bodies, and large species tend to evolve smaller bodies. This is itself one aspect of the more general phenomenon of island syndrome which describes the differences in morphology, ecology, physiology and behaviour of insular species compared to their continental counterparts. Following the arrival of humans and associated introduced predators, many giant as well as other island endemics have become extinct. A similar size increase, as well as increased woodiness, has been observed in some insular plants such as the Mapou tree in Mauritius which is also known as the "Mauritian baobab" although it is member of the grape family (Vitaceae).
Gigarcanum delcourti, formerly Hoplodactylus delcourti, is an extinct species of gecko in the family Diplodactylidae. It is the largest known of all geckos, with a snout-to-vent length (SVL) of 37 cm (14.6 in) and an overall length of at least 60 cm (23.6 in). It is only known from a single taxidermied specimen collected in the 19th century that was rediscovered unlabelled in a museum in France. The origin of the specimen was undocumented. While originally suggested to have been from New Zealand and the kawekaweau of Māori oral tradition, DNA evidence from the specimen suggests that it originates from New Caledonia.
Sorubim is a small genus of long-whiskered catfish native to tropical South America. A number of characteristics allows the differentiation of each species in the genus. Sorubim species are important food fish in South America and are highly significant to fisheries of some areas; however, harvests of these fish are not identified as much as other, more popular food fishes such as Colossoma, Arapaima, and Brachyplatystoma. Some species of this family are popular aquarium fish.
The terror skink, also called commonly Bocourt's terrific skink, Bocourt's eyelid skink and Bocourt's skink, is a species of lizard in the family Scincidae. The species is endemic to the Île des Pins, a small islet off the coast of New Caledonia. First described in 1876, the species was presumed to be extinct, but was rediscovered in 1993, and since then several individuals have been seen. Because of its small area of occupation and small population size, the International Union for Conservation of Nature has assessed its conservation status as being "critically endangered".
The flagtail swellshark is a little-known species of catshark, belonging to the family Scyliorhinidae, found at a depth of 480–700 m (1,570–2,300 ft) off northeastern Queensland, and possibly also nearby islands. This stout-bodied shark has a short, broad, and flattened head with a capacious mouth. Adults have a variegated brown coloration with 9–10 darker dorsal saddles and V-shaped blotch at the tip of the upper caudal fin lobe. Juveniles are yellow with narrow brown bars instead of saddles, and a distinctive marking between the spiracles shaped like two loops connected by a line. Like other swellsharks, this species can inflate its body when threatened.
The Diplodactylidae are a family in the suborder Gekkota (geckos), with over 150 species in 25 genera. These geckos occur in Australia, New Zealand, and New Caledonia. Diplodactylids are the most ecologically diverse and widespread family of geckos in both Australia and New Caledonia, and are the only family of geckos found in New Zealand. Three diplodactylid genera have recently been split into multiple new genera.
Pachydactylus rangei, the Namib sand gecko or Namib web-footed gecko, is a species of small lizard in the family Gekkonidae. It inhabits the arid areas of Angola, Namibia, and South Africa, and was first described in 1908 by Swedish zoologist Lars Gabriel Andersson, who named it after its finder, German geologist Dr. Paul Range.
Rhacodactylus trachycephalus, commonly known as the lesser rough-snouted giant gecko, dwarf rough-snouted giant gecko, or tough-snouted giant gecko, is a species of gecko endemic to two small areas of islands in New Caledonia. Its body grows to around 10 centimetres (3.9 in) and has a mosaic pattern with a variety of colors. Rhacodactylus trachyrhynchus is a closely related species, but R. trachycephalus is smaller and has a number of other noticeable differences. R. trachycephalus is viviparous, giving birth to only one or two young a year. Its restricted humid forest habitat is vulnerable due to multiple threats. As a result of habitat reduction, low reproduction rate and small population, it is one of the rarest geckos in the world.
