- Acapulco — A famous port city and world-renowned resort town located in the Mexican state of Guerrero, along the Pacific Ocean coast. Situated in a spectacular semicircular bay, it is historically celebrated for its vibrant nightlife, tropical beaches, and the legendary cliff diving shows at La Quebrada, while also holding great historical significance as a major Spanish colonial trading hub.
- Albuquerque — The largest city in the state of New Mexico, United States of America, founded in 1706 as a Spanish outpost. It serves as a major economic, cultural, and scientific hub, globally renowned for the International Balloon Fiesta, Sandia National Laboratories, and its traditional pueblo-style architecture deeply influenced by Hispanic and Native American cultures.
- Anahuac — A term of Nahuatl origin historically designating the central region of Mexico (the Valley of Mexico), structurally defined as the territorial and cultural core of the Aztec Empire. Literally meaning 'world between waters' or 'close to water', the name refers to the ancient lake system where the capital Tenochtitlan was founded, being used today both as a Mexican national identity symbol and as a name for various modern settlements in Mexico and the United States (Texas).
- Ancistrocactus megarhizus — An exotic species of miniature cactus native to the arid regions of Tamaulipas, Mexico, remarkable for its huge, tuberous taproot that often exceeds the volume of its aerial stem. The plant uses this massive underground structure as a strategic reservoir for water and nutrients, allowing it to survive in hyper-arid environments, while its outer globular body bears harsh yellow or grayish spines and produces spectacular greenish-yellow flowers.
- Ancistrocactus scheerii — A species of cactus native to the border regions of Texas and northern Mexican states, recognized by its oval or cylindrical deep green stem covered in spirals of prominent tubercles and rigid spines, with the central one ending in a well-defined hook. This rare plant develops elongated, bell-shaped flowers of greenish-yellow or purplish hue, being perfectly adapted to survival in extremely dry limestone soils and valued for its ecological resilience.
- Aporocactus — A genus of epiphytic or lithophytic plants in the family Cactaceae, native to the mountainous regions and forests of Mexico, characterized by long, slender, cylindrical, and creeping or pendulous stems covered with fine spines and large, tubular, brightly colored pink, red, or crimson flowers. In modern horticulture, the most famous species is Aporocactus flagelliformis (rat-tail cactus), widely cultivated in hanging baskets.
- Aporocactus flagelliformis — A species of epiphytic cactus native to Mexico, belonging to the genus Aporocactus (recently also classified as Disocactus flagelliformis), commonly known as the rat-tail cactus. It is characterized by long, cylindrical, pendulous, and flexible stems that can reach up to one meter in length, covered with fine bristles and large tubular, bright pink or magenta flowers, making it one of the most widely cultivated hanging basket plants.
- Aporocactus martianus — A rare species of epiphytic or lithophytic cactus native to Mexico (endemic to Oaxaca state), belonging to the genus Aporocactus (classified by some taxonomists as Disocactus martianus). It is distinguished by thick, deeply ribbed green trailing or pendulous stems (bearing 8-10 pronounced ribs), reddish-brown acicular spines, and large, tubular, bright scarlet-red flowers that remain open both day and night.
- Axolotl — A simplified phonetic variant or local linguistic adaptation for the noun 'axolotl', designating a rare species of neotenic salamander native to the Xochimilco lake complex in Mexico (Ambystoma mexicanum). This structurally remarkable amphibian is characterized by reaching sexual maturity without undergoing metamorphosis, retaining its branched external gills throughout its life and possessing a delicate and amazing capacity for complete regeneration of affected limbs and organs.
