The Mauritian giant skink (Leiolopisma mauritiana) is a large, extinct species of skink It was found only in Mauritius. It became extinct sometime in the 17th century, likely due to human-introduced predators.
The Réunion giant skink (Leiolopisma ceciliae), another extinct species, was closely related to the Mauritian giant skink. The Round Island ground skink (Leiolopisma telfairii) is a more distantly related surviving species from Mauritius.
Only a semi - complete specimen is known in addition to some odd bones. (Supposedly, a former director of the Mauritian Institute threw away specimens including some bones of this species). The remaining skeleton is missing the feet and digits, thus making it impossible for a SENI biometric analysis per se (Schnirel. 2004). The semi - complete skeleton does have a skull shaped similar to a blue-tongue skink (Tiliqua).
Little is known about this species. It is believed it grew up to around 80 centimeters (31 inches) in length, making it one of the largest skinks in history. [2]
The behavior of this animal is not well known or documented by any travelers to Mauritius when it was extant, however many things such as its diet and other aspects of its behavior can most likely be determined by extant skink species. It is very likely that the Mauritian giant skink shared behavioral traits with many other ground-based skinks such as the blue-tongued skink such as its diet and its overall temperament and speed. It may have been omnivorous, eating a diet of seeds, fruits, invertebrates and small lizards. It was also possibly capable of digging burrows. Its temperament was most likely very similar to that of modern ground skinks and was most likely a very tame animal that had relatively no fear of humans which might have played a part in its extinction.
The restoration undertaken by the (Species in Bronze Project), if accurate, gives a SENI value of .06 which would indicate that this species could have been fossorial or saxicolous in lifestyle. This is further linked by the fact that the closest living relative of this species (as mentioned by the restorers) is the Round Island ground skink (Leiolopisma telfairii). The Round Island ground skink also gives a SENI value of .06. The Round Island skink is a species capable of caudal autotomy. This skink is often seen darting in the underbrush or between rocks.
Pygomeles trivittatus is a skink in the. It appeared to be nested within the monotypic genus Androngo, but this species more recently was found to be more closely related to Pygomeles.
Eugongylus is a genus of skinks in the subfamily Eugongylinae. It was previously recognised as namesake of the Eugonglyus group of genera within Lygosominae, where it occupied a quite basal position. Members of this genus are commonly called mastiff skinks or short-legged giant skinks.
Janetaescincus is a genus of burrowing skinks in the family Scincidae. The genus is endemic to the Seychelles. There are two recognized species.
Leiolopisma is a genus of skinks. Most species occur in the region of New Caledonia-New Zealand, and they are related to other genera from that general area, such as Emoia; these and others form the Eugongylus group. One living and two extinct taxa represent a clade endemic to the Mascarenes.(Austin & Arnold 2006)
Blue-tongued skinks comprise the Australasian genus Tiliqua, which contains some of the largest members of the skink family (Scincidae). They are commonly called blue-tongued lizards or simply blue-tongues or blueys in Australia or panana in Indonesia. As suggested by these common names, a prominent characteristic of the genus is a large blue tongue that can be bared as bluff-warning to potential enemies. The type of predator/threat that is near will determine the intensity of colour present in the tongue. The tongue can also deform itself and produce a thick mucus in order to catch prey. They are relatively shy in comparison with other lizards, and also significantly slower due to their shorter legs.
The broad-billed parrot or raven parrot is a large extinct parrot in the family Psittaculidae. It was endemic to the Mascarene island of Mauritius. The species was first referred to as the "Indian raven" in Dutch ships' journals from 1598 onwards. Only a few brief contemporary descriptions and three depictions are known. It was first scientifically described from a subfossil mandible in 1866, but this was not linked to the old accounts until the rediscovery of a detailed 1601 sketch that matched both the subfossils and the accounts. It is unclear what other species it was most closely related to, but it has been classified as a member of the tribe Psittaculini, along with other Mascarene parrots. It had similarities with the Rodrigues parrot, and may have been closely related.
Round Island is an uninhabited islet 22.5 kilometres north of Mauritius. It has an area of 1.69 square kilometres and a maximum elevation of 280 metres. The island has been a nature reserve since 1957 and is administered jointly by the National Parks and Conservation Service and the Mauritian Wildlife Foundation. The island has been designated an Important Bird Area (IBA) by BirdLife International.
The hoopoe starling, also known as the Réunion starling or Bourbon crested starling, is a species of starling that lived on the Mascarene island of Réunion and became extinct in the 1850s. Its closest relatives were the also-extinct Rodrigues starling and Mauritius starling from nearby islands, and the three apparently originated in south-east Asia. The bird was first mentioned during the 17th century and was long thought to be related to the hoopoe, from which its name is derived. Some affinities have been proposed, but it was confirmed as a starling in a DNA study.
The red rail is an extinct species of rail that was endemic to the Mascarene island of Mauritius, east of Madagascar in the Indian Ocean. It had a close relative on Rodrigues island, the likewise extinct Rodrigues rail, with which it is sometimes considered congeneric, but their relationship with other rails is unclear. Rails often evolve flightlessness when adapting to isolated islands, free of mammalian predators, and that was also the case for this species. The red rail was a little larger than a chicken and had reddish, hairlike plumage, with dark legs and a long, curved beak. The wings were small, and its legs were slender for a bird of its size. It was similar to the Rodrigues rail, but was larger, and had proportionally shorter wings. It has been compared to a kiwi or a limpkin in appearance and behaviour.
The Mauritius sheldgoose, also known as the Mauritius shelduck, is an extinct species of sheldgoose that was endemic to the island of Mauritius. While geese were mentioned by visitors to Mauritius in the 17th century, few details were provided by these accounts. In 1893, a carpometacarpus wing-bone and a pelvis from the Mare aux Songes swamp were used to name a new species of comb duck, Sarcidiornis mauritianus. These bones were connected to the contemporary accounts of geese and later determined to belong to a species related to the Egyptian goose and placed in the sheldgoose genus Alopochen. The Mauritius and Réunion sheldgoose may have descended from Egyptian geese that colonised the Mascarene islands.
Leiolopisma telfairii, also known commonly as the Round Island ground skink, the Round Island skink, and Telfair's skink, is a species of lizard in the family Scincidae. The species is endemic to Round Island, one of the islands of Mauritius.
Gardiner's burrowing skink is a species of lizard in the family Scincidae. P. gardineri is the only species in the (monotypic) skink genus Pamelaescincus. The species is endemic to the Seychelles.
The saddle-backed Mauritius giant tortoise is an extinct species of giant tortoise in the family Testudinidae. It was endemic to Mauritius. The last records of this tortoise date to the early 18th century.
The domed Mauritius giant tortoise is an extinct species of giant tortoise. It was endemic to Mauritius.
The wildlife of Réunion is composed of its flora, fauna and funga. Being a small island, it only has nine native species of mammals, but ninety-one species of birds.
A circulus is a rarely occurring reptilian social group where there is interaction and personal exchange between individuals. Members will often protect and defend young, even if not of direct genetic linkage. Circulus is a Latin based term; one definition of the word is "a social gathering or circle company". Most reptiles are indifferent socially to each other as adults or to offspring.
Lygosominae is the largest subfamily of skinks in the family Scincidae. The subfamily can be divided into a number of genus groups. If the rarely used taxonomic rank of infrafamily is employed, the genus groups would be designated as such, but such a move would require a formal description according to the ICZN standards.
The Cape Verde giant skink, also called Bibron's skink, Cocteau's skink, and lagarto in Cape Verdean Portuguese, is a recently extinct species of large lizard (skink) that was endemic to some of the Barlavento Islands of Cape Verde before disappearing in the 20th century.
Ile aux Aigrettes is an islet off the south-east coast of Mauritius. It functions as a nature reserve and a scientific research station. It is also a popular visitors attraction — both for tourists and for Mauritians.
