Rhacodactylus Ciliatus IMG 7638-3s
''Rhacodactylus'' is a genus of medium to large geckos of the family Diplodactylidae. All species in this genus are found on the islands that make up New Caledonia. Genus characteristics include long limbs and toes with well-developed lamellae. Some webbing occurs on the hind limbs and toes. ''Rhacodactylus'' possess prehensile tails which also have lamellae to assist in climbing. These are for the most part arboreal geckos. ''Rhacodactylus'' are nocturnal geckos. The species are egg layers with the exception of ''Rhacodactylus trachyrhynchus'' and ''R. trachycephalus'' which gives live birth, a characteristic only otherwise found in New Zealand geckos. They also feed on lizards, more so than any of the family. ''Rhacodactylus'' geckos are sexually dimorphic, with the males possessing larger preanal pores than the females as well as a distinct hemipenis pocket. Males tend to be stockier than females with the exception of ''R. auriculatus'' in which species the males are muc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhacodactylus Leachianus
''Rhacodactylus leachianus'', commonly known as the New Caledonian giant gecko, Leach's giant gecko, Leachianus Gecko, or simply Leachie, is a large species of gecko in the family Diplodactylidae. The species, which was first described by Georges Cuvier in 1829, is endemic to New Caledonia. Taxonomy The specific name, ''leachianus'', is in honor of English zoologist William Elford Leach. Historically, there have been three recognized subspecies of ''R. leachianus'' (including the nominotypical subspecies): ''R. l. aubrianus'', ''R. l. henkeli'' (first described by Seipp and Obst in 1994), and ''R. l. leachianus''. However, based on recent molecular data, no populations of ''R. leachianus'' are granted subspecies status at the present time. Description ''R. leachianus'' is the largest extant gecko in the world and is considered an example of island gigantism. ''R. l. leachianus'', or the Grande Terre locality, is capable of growing 14-17″ (36-43cm) long, while ''R. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viviparity
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large vitellus, yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients b ...

Geckos Of New Caledonia
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 . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the cornea. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally lick the ...

Correlophus Sarasinorum
''Correlophus sarasinorum'', also called commonly Roux's giant gecko, Sarasins' giant gecko, Sarasin's icgiant 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. Etymology The specific name, ''sarasinorum'' (masculine, genitive, plural), is in honor of Swiss zoologists Karl Friedrich Sarasin and Paul Benedict Sarasin, who were cousins.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Rhacodactylus sarasinorum'', p. 233). Conservation status ''C. sarasinorum'' is currently being evaluated by CITES for protective status and is considered vulnerable to extinction in many herpetological circles. It has been found only in six locales in its native habitat. Description Since there is a considerable variation in snout-to-vent le ...

Rhacodactylus Trachycephalus
''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 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. Description ''R. trachycephalus'' has a body length of around and a snout-to-vent length of no more than , with its tail being roughly the same length as its body. The species' scales create a mosaic pattern, with patches of white, brown, grey, and gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhacodactylus Trachyrhynchus
The rough-snouted giant gecko (''Rhacodactylus trachyrhynchus''), also known as the greater rough-snouted gecko or tough-snouted gecko, is a species of gecko found in New Caledonia. Description The common name of the rough-snouted giant gecko refers to the enlarged scales that cover its snout. Other characteristics of this gecko include broad toes and a prehensile tail. the rough-snouted giant gecko has a mottled color pattern, generally a grayish-green to brown mixed with white. Its body length (BDL) is usually around , making it a large gecko species, with its tail being roughly the same length. Behavior and habitat The rough-snouted giant gecko is a nocturnal species, hunting in the nighttime and taking shelter in the daytime. It lives in forests, mostly in tropical and subtropical climates but also in forests with evergreen trees. It exhibits ovoviviparity, causing it to have a lower reproductive rate than other species in its genus. Like all ''Rhacodactylus'' geckos, th ...

Rhacodactylus Auriculatus
The gargoyle gecko, knob-headed giant gecko, New Caledonia bumpy gecko, or New Caledonian bumpy gecko (''Rhacodactylus auriculatus'') 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. Description This reptile gets its common name from the cranial bumps that give the appearance of horns or ears; in fact, ''auriculatus'' is Latin for "ears" or "eared", depending on the case. Other characteristics of this gecko include a thin prehensile tail which will regenerate if it drops off, as well as small adhesive toe pads. Although these geckos have the abili ...
