Insulasaurus arborens, also known as the Negros sphenomorphus, is a species of lizard of the family of Scincidae. It is endemic to the Philippines. [1] [2]
It is found on the islands of Negros, Panay, Pan de Azúcar and Masbate [2] at elevations below 1,600 m (5,200 ft). [1]
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon.
Squamata is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians, which are collectively known as squamates or scaled reptiles. With over 10,900 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Members of the order are distinguished by their skins, which bear horny scales or shields, and must periodically engage in molting. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamata is the most variably sized order of reptiles, ranging from the 16 mm (0.63 in) dwarf gecko to the 6.5 m (21 ft) Reticulated python and the now-extinct mosasaurs, which reached lengths over 14 m (46 ft).
Teiidae is a family of autarchoglossan lizards native to the Americas. Members of this family are generally known as whiptails or racerunners; however, tegus also belong to this family. Teiidae is sister to the Gymnopthalmidae, and both families comprise the Teiioidea. The Teiidae includes several parthenogenic species – a mode of clonal reproduction. Presently, the Teiidae consists of approximately 150 species in eighteen genera.
Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions.
Monitor lizards are lizards in the genus Varanus, the only extant genus in the family Varanidae. They are native to Africa, Asia, and Oceania, and one species is also found in the Americas as an invasive species. About 80 species are recognized.
The frilled lizard, also known commonly as the frill-necked lizard, is a species of lizard in the family Agamidae. It is endemic to northern Australia and southern New Guinea. This species is the only member of the genus Chlamydosaurus.
Toxicofera is a proposed clade of scaled reptiles (squamates) that includes the Serpentes (snakes), Anguimorpha and Iguania. Toxicofera contains about 4,600 species, of extant Squamata. It encompasses all venomous reptile species, as well as numerous related non-venomous species. There is little morphological evidence to support this grouping, however it has been recovered by all molecular analyses as of 2012.
The Asian water monitor is a large varanid lizard native to South and Southeast Asia. It is one of the most common monitor lizards in Asia, ranging from coastal northeast India, Bangladesh, Sri Lanka, mainland Southeast Asia, and southern China to Indonesian islands where it lives close to water. It is listed as Least Concern on the IUCN Red List. It was described by Laurenti in 1768 and is among the largest squamates in the world.
The Transvaal grass lizard, also known as the coppery grass lizard and Transvaal snake lizard is a species of lizard in the genus Chamaesaura. It is found in southern African grasslands and on slopes. The Transvaal grass lizard is ovoviparous. The scientific name refers to its copper colour.
Pseudorabdion mcnamarae is a species of snake in the family Colubridae. The species is endemic to the Philippines.
Gonocephalus sophiae, the Negros forest dragon is a species of lizards endemic to the Philippines. It is found between 0 and 1200 m above sea level on the islands of Negros, Mindanao and Panay, and possibly on Siargao, Luzon, Samar, Palawan and the Calamian Islands. The species is oviparous, and lays eggs in small holes dug in the banks of forest rivers. It is often confused with G. interruptus and G. semperi and therefore remains poorly characterized. Adults reach a total length of ca. 30 cm and feed mostly on insects.
The Christian scaly-toed gecko, also known commonly as Christian's scaly-toed gecko, is a species of lizard in the family Gekkonidae. The species is endemic to the Philippines.
Sphenomorphinae is a large subfamily of skinks, lizards within the family Scincidae. The genera in this subfamily were previously found to belong to the Sphenomorphus group in the large subfamily Lygosominae.
Eutropis englei, also known commonly as Engel's mabuya and the six-striped mabouya, is a species of skink, a lizard in the family Scincidae. The species is endemic to Mindanao in the Philippines.
Insulasaurus wrighti, also known commonly as Wright's sphenomorphus, is a species of skink, a lizard in the family Scincidae. The species is endemic to Palawan in the Philippines.
Huallasaurus is an extinct genus of saurolophine hadrosaur from the Late Cretaceous Los Alamitos Formation of Patagonia in Argentina. The type and only species is H. australis. Originally named as a species of Kritosaurus in 1984, it was long considered a synonym of Secernosaurus before being recognized as its own distinct genus in a 2022 study, different from other members of Kritosaurini.
Kelumapusaura is a genus of saurolophine hadrosaur from the Late Cretaceous Allen Formation in what is now Patagonia in Argentina. The type and only species is K. machi, known from a bonebed of various individuals.
Iguanodectes adujai is a species of freshwater fish that inhabits the rivers of South America. It largely prefers slow-moving blackwater habitats, though it has a slender body that suggests a further affinity for flowing water. It has a distinct lateral stripe in two horizontal sections, with bright-red at the top and yellow at the bottom.
Iguanodectes geisleri, the red-line lizard tetra, is a species of freshwater fish from South America. It is a small species, largely herbivorous with some omnivorous traits, that prefers to live in schools and is partial to shallow waters, especially in blackwater habitats. Some aspects of its body plan are unique amongst its genus, including the position and length of the anal fin.
Iguanodectes gracilis is a small species of freshwater fish from South America. It is known solely from the Rio Negro river system, which restricts its range only to Brazil. The name "gracilis" is in reference to a slender body shape, alongside the diminutive nature of I. gracilis - it is the smallest member of the genus Iguanodectes.
