Gulf Of California
The Gulf of California ( es, Golfo de California), also known as the Sea of Cortés (''Mar de Cortés'') or Sea of Cortez, or less commonly as the Vermilion Sea (''Mar Bermejo''), is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately . Rivers that flow into the Gulf of California include the Colorado, Fuerte, Mayo, Sinaloa, Sonora, and the Yaqui. The surface of the gulf is about . Maximum depths exceed because of the complex geology, linked to plate tectonics. The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. Parts of the Gulf of California are a UNESCO World Heritage Site.

Mexican State
The states of Mexico are first-level administrative territorial entities of the country of Mexico, which is officially named United Mexican States. There are 32 federal entities in Mexico (31 states and the capital, Mexico City, as a separate entity that is not formally a state). States are further divided into municipalities. Mexico City is divided in boroughs, officially designated as or , similar to other state's municipalities but with different administrative powers.

Baja California
Baja California (; 'Lower California'), officially the Free and Sovereign State of Baja California ( es, Estado Libre y Soberano de Baja California), is a state in Mexico. It is the northernmost and westernmost of the 32 federal entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of Baja California (). It has an area of (3.57% of the land mass of Mexico) and comprises the northern half of the Baja California Peninsula, north of the 28th parallel, plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean; on the east by Sonora, the U.S. state of Arizona, and the Gulf of California; on the north by the U.S. state of California; and on the south by Baja California Sur. The state has an estimated population of 3,769,020 as of 2020, significantly higher than the sparsely populated Baja California Sur to the south, and similar to San Diego County, California, to its north. Over 75% of t ...

Island
An island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. ...

Mexicali Municipality, Baja California
Mexicali Municipality is a municipality ( es, link=no, municipio) in the Mexican state of Baja California. Its municipal seat ( es, link=no, cabecera municipal) is located in the city of Mexicali. As of 2020, the municipality had a total population of 1,049,792. The municipality has an area of . This includes many smaller outlying communities as well as the city of Mexicali.

Reptile
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians ( tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...

Hypsiglena Ochrorhyncha
''Hypsiglena'' is a genus of small, rear-fanged, colubrid snakes commonly referred to as night snakes. The genus consists of nine species, and subspecies have been maintained pending further investigation.Mulcahy DG, Martínez-Gómez JE, Aguirre-León G, Cervantes-Pasqualli JA, Zug GR (2014).

Lichanura Trivirgata
The desert rosy boa (''Lichanura trivirgata'') is a species of snake in the family Boidae. The desert rosy boa is native to the American Southwest and Baja California and Sonora in Mexico. The desert rosy boa is one of four species in the boa family native to the continental United States, the other three being the coastal rosy boa ('' Lichanura orcutti'') and the two species of rubber boas ('' Charina''). Taxonomy Edward Drinker Cope described the species in 1861. The specific epithet ''trivirgata'' refers to the distinct three stripes characteristic of the species. Some researchers have placed the species in the genus ''Charina'' with the rubber boa (see synonymy). Newer phylogenetic research supports the original arrangement, but herpetologists are still not unified on rosy boa taxonomy. The subspecific designations are just as uncertain, with many sources not accepting ''L. t. arizonae'' or ''L. t. saslowi'', and others not recognizing any subspecies as being valid. S ...

Phyllodactylus Nocticolus
The peninsula leaf-toed gecko (''Phyllodactylus nocticolus'') is a medium-sized gecko. It is found in southern California (USA) and Baja California (Mexico), including many islands in Gulf of California as well as Islas Magdalena and Santa Margarita off the west coast of Baja California. Habitat The peninsula leaf-toed gecko occurs in areas of desert shrubs and large open rocks. When looking at their range we can see that they live only in a small part of California. They have been found in abundance starting at the border, continuing through Anza-Borrego Desert State park and stopping just north of Palm Springs Palm Springs (Cahuilla: ''Séc-he'') is a desert resort city in Riverside County, California, United States, within the Colorado Desert's Coachella Valley.

Sauromalus Hispidus
The Angel Island chuckwalla (''Sauromalus hispidus''), also known as the spiny chuckwalla, is a species of chuckwalla lizard belonging to the family Iguanidae endemic to Isla Ángel de la Guarda (Guardian Angel Island) in the Gulf of California. The species was transported to other islands by a tribe of the Seri as a potential food source. Taxonomy and etymology The generic name, ''Sauromalus'', is said to be a combination of two ancient Greek words: ''sauros'' meaning "lizard" and ''omalus'' meaning "flat". The proper ancient Greek word for "flat" is however ''homalos'' (ὁμαλός) or ''homalēs'' (ὁμαλής). Its specific name ''hispidus'' is Latin for "coarse" or "thorny" in reference to the spines on the chuckwalla's tail. The common name chuckwalla derives from the Shoshone word ''tcaxxwal'' or Cahuilla ''caxwal'', transcribed by Spaniards as ''chacahuala''. Description The Angel Island chuckwalla is the second-largest species of chuckwalla, reaching in body lengt ...
