Primates is an order of mammals, which is further divided into the strepsirrhines, which include lemurs, galagos, and lorisids; and the haplorhines, which include tarsiers and simians (monkeys and apes). Primates arose 74–63 million years ago first from small terrestrial mammals, which adapted for life in tropical forests: many primate characteristics represent adaptations to the challenging environment among tree tops, including large brain sizes, binocular vision, color vision, vocalizations, shoulder girdles allowing a large degree of movement in the upper limbs, and opposable thumbs (

family of amphibians in the frog order (Anura)

Pilosa is a order of xenarthran placental mammals, native to the Americas. They include anteaters and sloths (which include the extinct ground sloths). The name comes from the Latin word for "hairy".

Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic.

Cingulata, part of the superorder Xenarthra, is an order of armored New World placental mammals. The armadillos, whose species are split between the families Dasypodidae and Chlamyphoridae, are the only surviving members of the order. Two groups of cingulates much larger than extant armadillos (maximum body mass of 45 kg (100 lb) in the case of the giant armadillo) existed until recently: pampatheriids, which reached weights of up to 200 kg (440 lb) and chlamyphorid glyptodonts, which attained masses of 2,000 kg (4,400 lb) or more.

Bauhinia () is a large genus of flowering plants in the subfamily Cercidoideae and tribe Bauhinieae, in the large flowering plant family Fabaceae, with a pantropical distribution. The genus was named after the Bauhin brothers Gaspard and Johann, Swiss-French botanists.

Corydoras is a genus of freshwater ray-finned fish belonging to the family Callichthyidae, commonly referred to as the armoured catfishes, and the subfamily Corydoradinae, the corys. The species usually have more restricted areas of endemism than other callichthyids, but the area of distribution of the entire genus almost equals the area of distribution of the family, except for Panama where Corydoras is not present. Corydoras species are distributed in South America where they can be found from the east of the Andes to the Atlantic coast, from Trinidad to the Río de la Plata drainage in north

Callichthyidae is a family of catfishes (order Siluriformes), called armored catfishes due to the two rows of bony plates (or scutes) along the lengths of their bodies. It contains some of the most popular freshwater aquarium fish, such as many species in the genus Corydoras.

Tarsiiformes are a group of primates that once ranged across Europe, northern Africa, Asia, and North America, but whose extant species are all found in the islands of Southeast Asia. Tarsiers (family Tarsiidae) are the only living members of the infraorder; other members of Tarsiidae include the extinct Tarsius eocaenus from the Eocene, and Tarsius thailandicus from the Miocene. Two extinct genera, Xanthorhysis and Afrotarsius, are considered to be close relatives of the living tarsiers, and are generally classified within Tarsiiformes, with the former grouped within family Tarsiidae, and the

Hydrocynus is a genus of Characin fish in the family Alestidae commonly called "tigerfish," native to Africa. The genus name is derived from Ancient Greek ὕδωρ ("water") + κύων ("dog"). The genus contains five species, all commonly known as "African tigerfish" for their fierce predatory behaviour and other characteristics that make them excellent game fish. Hydrocynus are normally piscivorous, but H. vittatus is proven to prey on birds in flight.

Ostracion is a genus of marine ray-finned fishes belonging to the family Ostraciidae, the boxfishes. These fishes are found in the Indo-Pacific region as far east as the eastern Pacific coasts of the Americas.

Serranus is a genus of fish in the family Serranidae. It is one of five genera known commonly as the "Atlantic dwarf sea basses". These fish are hermaphrodites, each individual possessing functional male and female reproductive tissues. When a pair spawns, one fish acts as a male and the other acts as a female.

Osmerus is a genus of smelt.

genus of amphibians

The moonfish of the genus Mene, the sole extant genus of the family Menidae, are disk-shaped fish which bear a vague resemblance to gourami, thanks to their lateral compression and thread-like pelvic fins. Today, the genus is represented only by Mene maculata of the Indo-Pacific, where it is a popular food fish, especially in the Philippines, where it is known as bilong-bilong, chabita, hiwas or tahas.

Ratites () are a polyphyletic group consisting of all birds within the infraclass Palaeognathae that lack keels and cannot fly. They are mostly large, long-necked, and long-legged, the exception being the kiwi, which is also the only nocturnal extant ratite.

Isistius is a genus of dogfish sharks in the family Dalatiidae. They are commonly known as cookiecutter sharks. Members of the genus are known for their unusual behaviour and dentition.

Macrogomphus is a genus of dragonfly in the family Gomphidae. It contains the following species: Macrogomphus abnormis Selys, 1884 Macrogomphus annulatus (Selys, 1854) Macrogomphus borikhanensis Fraser, 1933 Macrogomphus decemlineatus Selys, 1878 Macrogomphus guilinensis Chao, 1982 Macrogomphus keiseri Lieftinck, 1955 Macrogomphus kerri Fraser, 1932 Macrogomphus lankanensis Fraser, 1933 Macrogomphus matsukii Asahina, 1986 †Macrogomphus menatensis Nel & Jouhalt, 2022 (fossil; Late Paleocene of France, Menat Formation) Macrogomphus montanus Selys, 1869 Macrogomphus parallelogramma (Burmeister,
