The gafftopsail catfish is a species of marine catfish found in the waters of the western central Atlantic Ocean, as well as the Gulf of Mexico and the Caribbean Sea. It has long, venomous spines which can cause painful wounds. It feeds on crustaceans and other fish. The male of the species fertilizes the eggs of the female, and broods them in his mouth until they hatch. The gafftopsail feeds throughout the water column. This fish is a common catch in the Southeastern US, although it may be found as far north as New York. They are considered strong fighters by anglers. They are taken from piers, jetties, reefs, and the surf, as well as bottom fishing or flats fishing. They are caught with hard lures as well as soft plastics, cut bait, and live or dead shrimp. Some fishermen use traps for catfish, a method regulated by some states.
The Pacific sharpnose shark often migrates along the Pacific coast of Mexico. They are most commonly caught in the artisanal fishery of Mazatlán. When a large sample of Pacific sharpnose sharks were observed scientists concluded that this type of shark was a "viviparous shark of small size which is born at an average length of 31 cm." Their gestation period is between ten and eleven months.
The bigeye trevally, also known as the bigeye jack, great trevally, six-banded trevally and dusky jack, is a species of widespread large marine fish classified in the jack family Carangidae. The bigeye trevally is distributed throughout the tropical waters of the Indian and Pacific Oceans, ranging from South Africa in the west to California and Ecuador in the east, including Australia to the south and Japan in the north. The bigeye trevally is best distinguished by its colouration, having a dark second dorsal fin with a white tip on the lobe, and also possessing a small dark spot on the operculum. Other more detailed anatomical features also set the species apart from other members of Caranx. The species is known to grow to a length of 120 cm and 18 kg.
The uniform crake is a species of bird in the subfamily Rallinae of the rail, crake, and coot family Rallidae. It is found in Mexico, most of Central America, and in nine South American countries.
The blue seedeater, or Cabanis's seedeater, is a species of bird in the cardinal family Cardinalidae that is found in southern Mexico and Central America. The Ecuadorian seedeater was formerly considered as a subspecies.
The golden cownose ray or Pacific cownose ray is a species of ray. It is found in the East Pacific along the coast of Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, and Peru. Its natural habitats are open seas, shallow seas, subtidal aquatic beds, estuarine waters, intertidal marshes, and coastal saline lagoons. They are often in schools, and sometimes associated with the spotted eagle ray.
The red grouper is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the western Atlantic Ocean.
The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed.
The Cerro del Pueblo Formation is a geological formation in Coahuila, Mexico, whose strata date back to the latest Campanian of the Late Cretaceous, just before the Campanian-Maastrichtian boundary. Dinosaur remains are among the fossils that have been recovered from the formation. The formation is believed to correlate with the Baculites reesidesi and Baculites jenseni ammonite zones, which dates it to 73.63-72.74 Ma.
Cavisomidae are a family of parasitic worms from the order Echinorhynchida.
Diplosentidae is a family of parasitic worms from the order Echinorhynchida.
Neoechinorhynchidae is a family of parasitic worms from the order Neoechinorhynchida.
Rhadinorhynchidae is a family of parasitic worms from the order Echinorhynchida.
Anopheles albimanus is a species of mosquito in the order Diptera. It is found in coastal Central and South America, the Caribbean, and Mexico. It is a generalist species and capable of wide dispersion. A. albimanus is a common malaria vector.
Opuntia matudae, or xoconostle, is a cactus native to Mexico. It is sometimes treated as a synonym of Opuntia hyptiacantha. In 2019, a genetic study supported keeping the taxa distinct.
The blue sea catfish, also known as the widehead sea catfish, is a species of sea catfish in the family Ariidae. It was described by Albert Günther in 1864, originally under the genus Arius. It is found in tropical marine, brackish and freshwater along the Pacific coast in Central America, ranging from Mexico to Panama as well as Nicaragua. It dwells at a depth range of 0 to 20 m. It reaches a maximum total length of 37 cm (15 in).
Aetobatus laticeps, the Pacific white-spotted eagle ray, is a species of cartilaginous fish in the eagle ray family Myliobatidae. It is found in the tropical East Pacific Ocean, ranging from Baja California to northern Peru, including the Galápagos. There has been recent evidence to suggest A.laticeps is in the Mexican tropical Pacific, more specifically in Chacahua Lagoon. However this evidence is insufficient and so the research being done on the spotted eagle rays in Chacahua Lagoon is working under the name A. narinari. Until 2014, it was included in the similar spotted eagle ray, but the two differ in genetics. Studies have been conducted to attempt to identify spot patterns at the individual level. A. laticeps and A. narinari both have white spots on the dorsal side of their dark body, making them difficult to differentiate. Following the split, A. narinari is restricted to the Atlantic, while the Indo-Pacific is inhabited by the closely related A. ocellatus.
The Spanish conquest of Nicaragua was the campaign undertaken by the Spanish conquistadores and their Tlaxcaltec allies against the natives of the territory now incorporated into the modern Central American republic of Nicaragua during the colonisation of the Americas. Before European contact in the early 16th century, Nicaragua was inhabited by a number of indigenous peoples. The west was inhabited by Mesoamerican groups such as the Nicarao, the Chorotega, and the Subtiaba. The Nicarao are a Nahua people closely related to the Mexica of Mexico. The Chorotega and the Subtiaba are closely related to the Zapotecs and Mixtecs of Oaxaca, Mexico due to their shared Otomanguean ethnicity. Other groups included the Matagalpa and the Tacacho, both of which mainly inhabited central Nicaragua.
