Dracaena paraguayensis, the Paraguay caiman lizard, is a species of lizard in the family Teiidae. [2] It is found in Northern Paraguay, Brazil and Bolivia.
Paraguay caiman lizards are closely related to the more well known northern caiman lizard, from which it differs especially in coloration, having light brown scales with dark banding rather than its relatives distinctive bright green and red. These lizards are known as 'caiman lizards' because of their noticeable resemblance to crocodilians, having rows of raised spikes in a croc-like arrangement.
They generally prefer dry climates and can often be found along the banks for rivers. Like all water tegus, they are semi-aquatic.
The family Alligatoridae of crocodylians includes alligators, caimans and their extinct relatives.
Teiidae is a family of Lacertoidean 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.
Dracaena, is a genus of lizards, also commonly called caiman lizards or water tegus, in the family Teiidae, along with tegus and ameivas. Caiman lizards are native to South America, where they are found in Brazil, Colombia, Ecuador, Paraguay, and Peru. These semiaquatic lizards spend a lot of time in the water and inhabit marshes, streams, and flooded forests. Caiman lizards often bask on branches overhanging the water.
Caiman is a genus of caimans within the alligatorid subfamily Caimaninae. They inhabit Central and South America. They are relatively small sized crocodilians, with all species reaching lengths of only a couple of meters and weighing 6 to 40 kg on average.
Draco is the Greco-Latin word for serpent, or dragon.
The yacare caiman, also known commonly as the jacare caiman, Paraguayan caiman, piranha caiman, red caiman, and southern spectacled caiman, is a species of caiman, a crocodilian in the family Alligatoridae. The species is endemic to Argentina, Bolivia, Brazil, and Paraguay. Brown in color and covered with dark blotches, males grow to a total length of 2–3 m and weigh around 40–50 kg (88–110 lb); while females grow to 1.4 m long and about 15–20 kg (33–44 lb). Typical habitats of this caiman include lakes, rivers, and wetlands. Its diet primarily consists of aquatic animals, such as snails, and occasionally land vertebrates. Mating occurs in the rainy season and eggs hatch in March, with young fending for themselves as soon as they hatch. The yacare caiman was hunted heavily for its skin to use for leather in the 1980s, which caused its population to decrease significantly. However, trading restrictions placed since have caused its population to increase. Its population in the Pantanal is about 10 million, and it is listed as least concern on the IUCN Red List.

Dracaena draco, the Canary Islands dragon tree or drago, is a subtropical tree in the genus Dracaena, native to the Canary Islands, Cape Verde, Madeira, western Morocco, and possibly introduced into the Azores.
The broad-snouted caiman is a crocodilian in the family Alligatoridae found in eastern and central South America, including the Pantanal habitat of Bolivia, Southeast Brazil, and Paraguay, as well as northern Argentina and Uruguay. Behind the black caiman, it is the second-largest caiman species; it is the third-largest alligatorid behind the American alligator and the aforementioned black caiman. Primarily, the species inhabits freshwater wetlands, including floodplains, marshes, swamps, and some mangrove forests, as well as various streams, rivers, lakes or ponds, preferring bodies of rather still or slower-moving water. They will often utilize man-made cow ponds, disused stock tanks, and canals and ditches, as well.
Cuvier's dwarf caiman is a small crocodilian in the alligator family from northern and central South America. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, Trinidad and Venezuela. It lives in riverine forests, flooded forests near lakes, and near fast-flowing rivers and streams. It can traverse dry land to reach temporary pools and tolerates colder water than other species of caimans. Other common names for this species include the musky caiman, the dwarf caiman, Cuvier's caiman, and the smooth-fronted caiman. It is sometimes kept in captivity as a pet and may be referred to as the wedge-head caiman by the pet trade community.
The scale-throated hermit is a species in the hummingbird family Trochilidae. It is found in Argentina, Brazil, and Paraguay.
The spectacled caiman, also known as the white caiman, common caiman, and speckled caiman, is a crocodilian in the family Alligatoridae. It is brownish-, greenish-, or yellowish-gray colored and has a spectacle-like ridge between its eyes, which is where its common name come from. It grows to a length of 1.4–2.5 m and a weight of 7–40 kg (15–88 lb), with males being both longer and heavier than females. Its diet varies seasonally, commonly consisting of crabs, fish, small mammals, amphibians and snails. Breeding occurs from May to August and 14–40 eggs are laid in July and August. This crocodilian has a large range and population; it is native to much of Latin America, and has been introduced to the United States, Cuba, and Puerto Rico.
Otuquis National Park and Integrated Management Natural Area,, is a national park in the Pantanal ecoregion of southeastern Bolivia. It is named after the Otuke indigenous people who inhabit the region.
The northern caiman lizard is a species of lizard found in northern South America.
Butia paraguayensis is a species of Butia palm tree found in the cerrado region of South America. Its natural range runs from Mato Grosso do Sul and São Paulo in southern Brazil through Paraguay to northern Argentina and Uruguay. It was given the name dwarf yatay palm in English by 2000, and it is locally known as yata'i in Guaraní in Paraguay, or butiá-do-cerrado in Portuguese in Rio Grande do Sul, Brazil.
Tegu is a common name of a number of species of lizards that belong to the families Teiidae and Gymnophthalmidae. Tegus are native to Central and South America. They occupy a variety of habitats and are known for their large size and predatory habits.
Paradracaena is an extinct genus of lizards from northern South America. Fossils of Paradracaena colombiana have been found in the Honda Group of Colombia, Peru and Brazil. The species was described as a member of the tegus; Tupinambis huilensis by Estes in 1961.
The northern green anaconda is a disputed boa species found in northern South America and the Caribbean island of Trinidad. It is closely related to Eunectes murinus, the (southern) green anaconda, from which it was claimed to be genetically distinct in 2024. It is one of the heaviest and longest snakes in the world, with one specimen reported by a newspaper to have been 6.3 metres (21 ft) long. Like all boas, it is a non-venomous constrictor. E. akayima is estimated to have diverged from its closest relative between 5 and 20 million years ago, originally separated by the Vaupés Arch. Today, specimens of E. akayima are known from the Orinoco basin and surrounding regions, ranging from Ecuador to Trinidad. Its range is still mostly separate from that of E. murinus, although they partially overlap around French Guiana, with no clear geographical barrier. While allegedly separated through mitochondrial DNA markers, the two species are indistinguishable in morphology.
