The arapaima, pirarucu, or paiche is any large species of bonytongue in the genus Arapaima native to the Amazon and Essequibo basins of South America. Arapaima is the type genus of the subfamily Arapaiminae within the family Osteoglossidae. They are among the world's largest freshwater fish, reaching as much as 3 m (9.8 ft) in length. They are an important food fish. They have declined in the native range due to overfishing and habitat loss. In contrast, arapaima have been introduced to several tropical regions outside the native range, where they are sometimes considered invasive species. In Kerala, India, arapaima escaped from aquaculture ponds after floods in 2018. Its Portuguese name, pirarucu, derives from the Tupi language words pira and urucum, meaning "red fish".

The desert tortoise, is a species of tortoise in the family Testudinidae. The species is native to the Mojave and Sonoran Deserts of the southwestern United States and northwestern Mexico, and to the Sinaloan thornscrub of northwestern Mexico. G. agassizii is distributed in western Arizona, southeastern California, southern Nevada, and southwestern Utah. The specific name agassizii is in honor of Swiss-American zoologist Jean Louis Rodolphe Agassiz. The desert tortoise is the official state reptile in California and Nevada.
Gopherus is a genus of fossorial tortoises commonly referred to as gopher tortoises. The gopher tortoise is grouped with land tortoises that originated 60 million years ago, in North America. A genetic study has shown that their closest relatives are in the Asian genus Manouria. The gopher tortoises live in the southern United States from California's Mojave Desert across to Florida, and in parts of northern Mexico. Gopher tortoises are so named because of some species' habit of digging large, deep burrows. Most notably, Gopherus polyphemus digs burrows which can be up to 40 feet (12 m) in length and 10 feet (3.0 m) in depth. These burrows are used by a variety of other species, including mammals, other reptiles, amphibians, and birds. Gopher tortoises are 20–50 cm (7.9–19.7 in) in length, depending on the species. All six species are found in xeric habitats. Numerous extinct species are known, the oldest dating to the Priabonian stage of the Late Eocene of the United States.
Agassiz's perchlet, also known as Agassiz's glass fish and the olive perchlet, is a species of ray-finned fish in the family Ambassidae. It is semi-transparent with dark scale edges forming a pattern over most of the body. It grows to a maximum of 7.5 cm. It is a macrophyte spawner with adhesive eggs. It is endemic to Australia. It was named for the zoologist Louis Agassiz.
Ambassis is a genus of fish in the family Ambassidae, the Asiatic glassfishes. They are found widely in the Indo-Pacific region, with species in fresh, brackish and coastal marine waters.
Apistogramma agassizii, commonly known as Agassiz's dwarf cichlid, is a species of cichlid found in the Marañón and Ucayali River in Peru, some tributaries of the Amazon River, as well as downstream to the estuary in the Atlantic. It is named after the Swiss-American zoologist and geologist Louis Agassiz (1807-1873).
Leptochilichthys is a genus of marine smelts containing four species. Leptochilichthys is the only genus in the former family Leptochilichthyidae but is now included within the broader family Alepocephalidae.

The Rio skate is a shallow water skate native to the Atlantic coast of South America from Brazil to southern Argentina. It is the only member of the monotypic genus Rioraja.
Liparis is a large genus of snailfish from the northern hemisphere. They are very common in temperate and cold waters. Chernova (2008) has proposed that the genus should be subdivided into five subgenera: Liparis, Neoliparis, Lycocara, Careliparis, and Lyoliparis.
Actinopyga agassizii, commonly known as five-toothed sea cucumber or West Indian sea cucumber, is a species of sea cucumber in the family Holothuriidae. It was first described by German zoologist Emil Selenka in 1867. It is native to the Western Atlantic region, including the Gulf of Mexico and the Caribbean Sea, and is harvested for food.
Corydoras agassizii is a species of catfish found in the Amazon basin. It can be found in the border area of Peru and Brazil. It lives in tropical waters with a water temperature of 22 - 26 °C, a pH of 6.0 - 8.0 and a hardness of 2 - 25 dH.
Agassiz' smooth-head is a species of fish in the family Alepocephalidae. It is named for the scientist and engineer Alexander Agassiz (1835–1910), who commanded the 1899 survey aboard the USS Albatross on which the fish was discovered.
