Heloderma Exasperatum
The Rio Fuerte beaded lizard (''Heloderma exasperatum'') is a venomous species of beaded lizard in the family Helodermatidae. It is found in the tropical forests and shrublands of western Mexico, specifically around the Rio Fuerte and Rio Mayo basins. It is often found in or near abandoned mammal burrows and sources of water. Geographic range ''H. exasperatum'' is found in southwestern Chihuahua and southern Sonora, Mexico, up to an altitude of .

Chihuahua (state)
Chihuahua (), officially the Free and Sovereign State of Chihuahua ( es, Estado Libre y Soberano de Chihuahua), is one of the 31 states which, along with Mexico City, comprise the 32 federal entities of Mexico. It is located in northwestern Mexico, and is bordered by the states of Sonora to the west, Sinaloa to the southwest, Durango to the south, and Coahuila to the east. To the north and northeast, it shares an extensive border with the U.S. adjacent to the U.S. states of New Mexico and Texas. Its capital city is Chihuahua City; the largest city is Ciudad Juárez. Although Chihuahua is primarily identified with its namesake, the Chihuahuan Desert, it has more forests than any other state in Mexico, aside from Durango. Due to its variant climate, the state has a large variety of fauna and flora. The state is mostly characterized by rugged mountainous terrain and wide river valleys. The Sierra Madre Occidental mountain range, part of the continental spine that also inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venomous Lizards
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. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals as bi ...

Sonoran–Sinaloan Transition Subtropical Dry Forest
The Sonoran–Sinaloan transition subtropical dry forest is a Tropical and subtropical dry broadleaf forests, tropical dry broadleaf forest ecoregion in northwestern Mexico. Geography This ecoregion forms a transition belt between the Sonoran Desert to the north and the Sinaloan dry forests to the south, running south from the foothills of the Sierra Madre Occidental highlands of the state of Sonora to the Pacific Ocean coasts of Sonora and Sinaloa. This region is also part of the transition zone between the Nearctic realm, Nearctic and Neotropical realms and as such habitats of the region range from sparse semi-desert in the north to dry forest in the south. It covers an area of from sea level to . Climate The climate is subtropical and semi-arid. Annual rainfall is , and comes mostly in the summer months. Flora The characteristic vegetation is deciduous thorn forest and woodland ("selva espinosa"), with areas of thorn scrub. Characteristic trees include the boat-thorn acacia ...

Endemic Reptiles Of Mexico
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oviparity
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mexican Beaded Lizard
The Mexican beaded lizard (''Heloderma horridum'') is a species of lizard in the family Helodermatidae The Helodermatidae or beaded lizards are a small family of lizards endemic to North America today, but formerly more widespread in the ancient past. Traditionally, the Gila monster and the Mexican beaded lizard were the only species recognized, ..., one of the two species of venomous beaded lizards found principally in Mexico and southern Guatemala. It and congener (biology), the other member of the same genus, the Gila monster (''Heloderma suspectum''), are the only lizards known to have evolved an overt venom delivery system. The Mexican beaded lizard is larger than the Gila monster, with duller coloration, black with yellowish bands. As it is a specialized predator that feeds primarily upon eggs, the primary use of its venom is still a source of debate among scientists. This venom has been found to contain several enzymes useful for manufacturing drugs in the treatment of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Helodermatidae
The Helodermatidae or beaded lizards are a small family of lizards endemic to North America today, but formerly more widespread in the ancient past. Traditionally, the Gila monster and the Mexican beaded lizard were the only species recognized, although the latter has recently been split into several species. While the fossil record of this family may date back to as far as the Cretaceous with genera such as '' Primaderma'' and '' Paraderma'' of North America, the oldest definitive members of the Helodermatidae date to the Early Oligocene, with ''Lowesaurus matthewi'' from North America (Nebraska) and ''Euheloderma gallicum'' from Europe Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions.
