Monilesaurus acanthocephalus, the spiny-headed lizard, is a species of agamid lizard. It is endemic to India. [1]
Lizards are a widespread group of squamate reptiles, with over 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic as it excludes the snakes and Amphisbaenia; 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. 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 5.21 m (17.1 ft) green anaconda and the now-extinct mosasaurs, which reached lengths over 14 m (46 ft).
Calotes is a genus of lizards in the draconine clade of the family Agamidae. The genus contains 25 species. Some species are known as forest lizards, others as "bloodsuckers" due to their red heads, and yet others as garden lizards.
The Lizard is a fictional character appearing in American comic books published by Marvel Comics. Created by Stan Lee and Steve Ditko, he first appeared in The Amazing Spider-Man #6 as an enemy of the superhero Spider-Man. The Lizard is primarily depicted as a villainous alternate personality of Connors, who takes over his mind and evolves after each transformation, slowly becoming the predominant personality. Despite this, the Lizard has also been portrayed as an antihero and ally of Spider-Man in various instances. Connors is sometimes an ally of Spider-Man just as himself, and not necessarily as his alter ego. He is also the husband of Martha Connors, and the father of Billy Connors.
Monitor lizards are large lizards in the genus Varanus. 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 Servarayan hills, with the anglicised name Shevaroy Hills, are a towering mountain range near the city of Salem, in Tamil Nadu state, southern India. It is one of the major hill stations in Tamil Nadu and in the Eastern Ghats.
Iguania is an infraorder of squamate reptiles that includes iguanas, chameleons, agamids, and New World lizards like anoles and phrynosomatids. Using morphological features as a guide to evolutionary relationships, the Iguania are believed to form the sister group to the remainder of the Squamata, and comprise nearly 13,000 named species. However, molecular information has placed Iguania well within the Squamata as sister taxa to the Anguimorpha and closely related to snakes. The order has been under debate and revisions after being classified by Charles Lewis Camp in 1923 due to difficulties finding adequate synapomorphic morphological characteristics. Most Iguanias are arboreal but there are several terrestrial groups. They usually have primitive fleshy, non-prehensile tongues, although the tongue is highly modified in chameleons. The group has a fossil record that extends back to the Early Jurassic. Today they are scattered occurring in Madagascar, the Fiji and Friendly Islands and Western Hemisphere
Acanthocephalus is a genus of the botanical family Asteraceae described as a genus in 1842.
Acanthocephalus is a genus of parasitic worms. One of the species in this genus is Acanthocephalus anguillae, a fish parasite. Acanthocephalans are also found in humans and primates, causing a common zoonotic infection called "human acanthocephaliasis". While pathogens can be transferred among animals and humans, the main source of human acanthocephaliasis is the diet of infected raw fish and insects.
Microauris is a monotypic genus of agamid lizard. Its only species is Microauris aurantolabium, also known as the small-eared dragon or orange-lipped forest lizard, found in the forests of the southern Western Ghats and is currently known from the Kalakkad Mundanthurai Tiger Reserve. The species was formerly included in Pseudocalotes andamanensis of the Andaman Islands, but recognized as distinct in 2008. It was also classified under Calotes until 2018, where it was transferred to its own genus, Microauris, on the basis of its divergence from Calotes.
The Draconinae are a subfamily of reptiles in the family Agamidae found in southern Asia and Oceania. Some taxonomists believe these genera belong to the subfamily Agaminae.
Acanthocephalus may refer to:
Acanthocephalus anguillae is a species of parasitic worm in the phylum Acanthocephala. An intestinal parasite, it is found both in the Baltic Sea and along the coast of California, where it is often found in the fore- and mid-gut of the Brown and Rainbow trouts.
Acanthocephalus echigoensis is a species of parasitic worm in the phylum Acanthocephala. Found both in California and in Thailand, it has been known to parasitize the sockeye salmon, chum salmon, rainbow trout, and barramundi.
Acanthocephalus dirus is a species of parasitic worm in the Echinorhynchidae family. Instead of having its eggs expelled from the host in feces, the gravid female detaches itself from the host's digestive tract and sinks to the bottom, where her body is consumed by the species' intermediate host, Caecidotea intermedius, a species of isopod. Upon hatching, the larvae begin to alter their host's behavior. This will manifest in lighter pigmentation and an increased attraction to predators, such as A. dirus' primary hosts.
