The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a large reptile of the monitor lizard family Varanidae that is endemic to the Indonesian islands of Komodo, Rinca, Flores, Gili Dasami, and Gili Motang. The largest extant population lives within the Komodo National Park in Eastern Indonesia. It is the largest extant species of lizard, with the males growing to a maximum length of 3 m (10 ft) and weighing up to 150 kg (330 lb). As a result of their size, which is exceptional among reptiles, Komodo dragons are apex predators, dominating the ecosystems in which they live. Komodo dragons hunt and ambush prey; juveniles take small prey like invertebrates or birds, and…

Currently there are about 40 extant families of Lacertilia. These vary considerably, e.g. in shades, colours, and sizes. For example, the largest representative among Geckos, the New Caledonian giant gecko (Rhacodactylus leachianus), has a length of up to 36 cm (14 in), while the largest species in the family Varanidae, Komodo dragon (Varanus komodoensis), has a length up to 3 metres (10 ft), and a body mass of 70 kg (154 lbs).

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 southern United States as an invasive species. About 94 species are recognized. Monitor lizards have long necks, powerful tails and claws, and well-developed limbs. The adult length of extant species ranges from 20 cm (7.9 in) in some species such as Varanus sparnus, to over 3 m (10 ft) in the case of the Komodo dragon, though the extinct megalania (Varanus priscus) may have reached lengths of more than 7 m (23 ft). Most monitor species are terrestrial, but many are also arboreal or semiaquatic. While most monitor…

The Musculoskeletal Anatomy of the Komodo Dragon's Hindlimb (<i>Varanus komodoensis</i>, Varanidae).. The Komodo dragon ( Varanus komodoensis ) is the largest extant lizard and is classified as an endangered species. Despite its rarity, anatomical studies on this species remain limited, hindering a comprehensive understanding of its biology and evolutionary traits. This research presents a detailed anatomical and histological examination of the pelvic limb of a female Komodo dragon, providing valuable insights into the musculoskeletal system of this species. A series of measurements and observations were made on the bones of the pelvic limb, including the femur, tibia, fibula, and pes, all…

Sex chromosome dosage compensation in a sex reversing skink is not influenced by sexual phenotype.. Background Lizards have sex determination systems that can differ between even closely related species. These include XY and ZW systems, and thermolabile systems where genes and temperature interact to determine sex. The eastern three-lined skink (Bassiana duperreyi) has a differentiated XY sex determination system, in which low temperature incubation during development can cause female to male sex reversal, producing XX males. This provides a unique opportunity to investigate how genotype and sexual phenotype affect dosage compensation. Results Here, we present a draft genome assembly of the…

Histological and histochemical characterisation of the salivary glands of the palatine fold and the mandibular venom gland of the Komodo dragon (Varanus komodoensis).. The Komodo dragon (Varanus komodoensis) is the largest living lizard whose hunting strategy allows it to attack large animals. It inflicts serious damage to its prey with specially developed teeth, called ziphodonts. Although the mandibular venom gland system was previously detected in the Komodo dragon, there is still a lack of its histochemical analysis. Thus, the objective of the current study was a detailed description of the mandibular venom gland of this species. In addition, a histological examination of the salivary g…

New beautiful, dragon-like species of lizard discovered in the Tropical Andes. Tweet The Huallaga River in the Andes of central Peru extends for 1,138 km, making it the largest tributary of the Marañón River, the spinal cord of the Amazon River. This basin harbours a great variety of ecosystems, including the Peruvian Yunga ecoregion, which is considered a shelter of endemic birds, mammals, reptiles and amphibians.

Komodo National Park (Indonesian: Taman Nasional Komodo) is a national park in Indonesia within the Lesser Sunda Islands in the border region between the provinces of East Nusa Tenggara and West Nusa Tenggara. The park includes the three larger islands—Komodo, Padar and Rinca—and 26 smaller ones, with a total area of 1,733 km2 (669 sq mi), with 603 km2 (233 sq mi) of it land. The park was founded in 1980 to protect the Komodo dragon, the world's largest lizard. Later it was dedicated to protecting other species, including marine species. In 1991 the park was declared a UNESCO World Heritage Site and a Man and Biosphere Reserve. It is considered one of the world's 25 biodiversity hotspots. K…

Megalania (Varanus priscus) is an extinct species of giant monitor lizard, part of the megafaunal assemblage that inhabited Australia during the Pleistocene. It is the largest terrestrial lizard known to have existed, but the fragmentary nature of known remains make estimates highly uncertain. Studies suggest that most known specimens would have reached around 2–2.4 m (6 ft 7 in – 7 ft 10 in) in body length excluding the tail, while some individuals would have been significantly larger, reaching sizes around 4.5 m (15 ft), 5.5 m (18 ft) or perhaps even 7 m (23 ft) in total length. Megalania is thought to have had a similar ecology to the living Komodo dragon (Varanus komodoensis) which may…

The largest extant animal, as well as the largest animal to ever exist, is the blue whale. The maximum recorded weight was 190 tonnes for a specimen measuring 27.6 metres (91 ft), whereas longer ones, up to 33.6 metres (110 ft), have been recorded but not weighed. It is estimated that this individual could have a mass of 250 tonnes or more. The longest non-colonial animal is the lion's mane jellyfish (120 ft, 36.6 m). While controversial, estimates for the weight of the sauropod Bruhathkayosaurus suggest it was around 110–170 tons, with the highest estimate being 240 tons, if scaled with Patagotitan, although actual fossil remains no longer exist, and that estimation is based on described d…

Isolated dwarfism and sexual dimorphism in a mainland population of the greater short-horned lizard (Phrynosoma hernandesi) and the Great Plains toad (Anaxyrus cognatus).. Body size is an important biological concept as it impacts nearly all aspects of an organism. In mainland systems, body size tends to show clinal variation; however, drastic body size shifts are typically limited to insular systems in correspondence with abrupt changes in climate patterns and resource availability, often in coordination with reduced genetic diversity. We investigate a rare occurrence of dwarfism and its influence on sexual size dimorphism (SSD) among two mainland species inhabiting the San Luis Valley (Va…

Status of the largest extant population of the critically endangered Aeolian lizard Podarcis raffonei (Capo Grosso, Vulcano island). The Aeolian wall lizard Podarcis raffonei is an island endemic that survives only on three tiny islets, and on the Capo Grosso peninsula of the Vulcano island, thus is among the European vertebrates with the smallest range and one of the most threatened by extinction. This species is declining due to competition and hybridization with the non-native lizard Podarcis siculus , but a regular monitoring program is lacking. Here we assessed the size and status of the Capo Grosso population of P . raffonei on Vulcano. In September 2015 we captured 30 individuals sho…
