Butterfly Goodeid
The butterfly splitfin or butterfly goodeid (''Ameca splendens'') is a bony fish from the monotypic genus ''Ameca'' of the splitfin family (Goodeidae). It was formerly found throughout the Ameca River drainage in Mexico; the type locality is Rio Teuchitlán in the vicinity of Teuchitlán, Jalisco, near the town of Ameca. The species was historically only found in an area about 10 miles (15 km) in diameter but in the early 21st century, searches have found it in a few other locations in the region, up to 100 km away at Cuyacapán. Today, the species is rated as critically endangered by the IUCN. A remnant population was found to persist in El Rincón waterpark, where the Rio Teuchitlán's springs have been dammed for bathing, between Teuchitlán town and he prehistoric site of Guachimontones, but it is unclear if this population still survives. Possibly, it also exists in a feral state in the United States; individuals apparently derived from escaped or introduced captive s ...

Andropodium
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish (Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish (Chondrichthyes) and jawless fish (Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are predominantly a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jalisco
Jalisco, officially the Free and Sovereign State of Jalisco, is one of the 31 states which, along with Mexico City, comprise the 32 Political divisions of Mexico, Federal Entities of Mexico. It is located in western Mexico and is bordered by six states, Nayarit, Zacatecas, Aguascalientes, Guanajuato, Michoacán, and Colima. Jalisco is divided into Municipalities of Jalisco, 125 municipalities, and its capital and largest city is Guadalajara. Jalisco is one of the most economically and culturally important states in Mexico, owing to its natural resources as well as its long history and culture. Many of the characteristic traits of Mexican culture are originally from Jalisco, such as mariachi, tequila, ranchera, ranchera music, birria, jaripeo, etc., hence the state's motto: ('Jalisco is Mexico'). Economically, it is ranked third in the country, with industries centered in the Guadalajara metropolitan area, the third largest metropolitan area in Mexico. The state is home to two ...

Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Aquarist
An aquarist is a person who manages aquariums, either professionally or as a hobby. They typically care for aquatic animals, including fish and marine invertebrates. Some may care for aquatic mammals. Aquarists often work at public aquariums. They may also work at nature reserves, zoos, and amusement parks. Some aquarists conduct field research outdoors. In business, aquarists may work at pet stores, as commercial fish breeders, or as manufacturers. Some aquarists are hobbyists, also known as "home aquarists," who may vary in skills and experience. History People have cared for aquatic animals since ancient times. The Sumerians kept fish in ponds as early as 2500 BCE. Pliny the Elder wrote of people who kept fish as oracles, and ancient Agrigent was believed to have fish ponds. The Roman poet Rutilus Namatianus wrote of a Etrurian Jew who kept fish in opaque tanks. By the 10th century, goldfish were popular pets in China. In 1369, Emperor Hung Wu established a porcelain fact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevada
Nevada ( ; ) is a landlocked state in the Western United States. It borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the seventh-most extensive, the 32nd-most populous, and the ninth-least densely populated U.S. state.

Feral
A feral (; ) animal or plant is one that lives in the wild but is descended from domesticated individuals. As with an introduced species, the introduction of feral animals or plants to non-native regions may disrupt ecosystems and has, in some cases, contributed to extinction of indigenous species. The removal of feral species is a major focus of island restoration. Animals A feral animal is one that has escaped from a domestic or captive status and is living more or less as a wild animal, or one that is descended from such animals. Other definitions include animals that have changed from being domesticated to being wild, natural, or untamed. Some common examples of animals with feral populations are horses, dogs, goats, cats, rabbits, camels, and pigs. Zoologists generally exclude from the feral category animals that were genuinely wild before they escaped from captivity: neither lions escaped from a zoo nor the white-tailed eagles re-introduced to the UK are regarded ...

Waterpark
A water park (also waterpark, water world, or aquapark) is an amusement park that features water play areas such as swimming pools, water slides, splash pads, water playgrounds, and lazy rivers, as well as areas for floating, bathing, swimming, and other barefoot environments. Modern water parks may also be equipped with some type of artificial surfing or bodyboarding environment, such as a wave pool or flowrider. History Water parks have grown in popularity since their roots of public swimming pools in the late 1940s and early 1950s. The United States has the largest and most concentrated water park market, with over 1,000 water parks and dozens of new parks opening each year. Major organizations are the IAAPA (International Association of Amusement Parks and Attractions) and WWA ( World Waterpark Association), which is the industry trade association. Water parks which emerge from spas tend to more closely resemble mountain resorts, as they become year-round destinatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education.

Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...
