The Pedetidae are a family of rodents. The two living species, the springhares, are distributed throughout much of Southern Africa and also around Kenya, Tanzania, and Uganda. Fossils have been found as far north as Turkey. Together with the anomalures and zenkerella, Pedetidae forms the suborder Anomaluromorpha. The fossil genus Parapedetes is also related.

Galeus is a genus of deepwater catshark, belonging to the family Pentanchidae, commonly known as sawtail catsharks in reference to a distinctive saw-toothed crest of enlarged dermal denticles, found along the upper edges of their caudal fins. They are found in the Atlantic, the western and central Pacific, and the Gulf of California, inhabiting deep waters at or close to the sea floor. Members of this genus are rather small, slim sharks with firm bodies and thick, rough skin. Their heads are usually fairly long and pointed, and have large mouths with well-developed furrows at the corners. They

Rhinoclemmys is a genus of turtles in the family Geoemydidae (formerly Bataguridae), the only genus in the subfamily Rhinoclemmydinae. Member species of the genus are commonly known as the Neotropical wood turtles and are the only geoemydids known from the Americas. As such, they have adapted to a wide range of habitats, which is reflected in the species' common names.

Deania is a genus of long-snouted, deepwater dogfish sharks in the family Centrophoridae.

The genus Eligmodontia consists of five or six species of South American sigmodontine mice restricted to Bolivia, Chile, and Argentina. Species of Eligmodontia occur along the eastern side of the Andes Mountains, in Patagonia, and in the Chaco thorn forest of South America. They can be found in arid and semiarid habitats and in both high and low elevation areas. These rodents are commonly known as gerbil mice or by their local name lauchas. Sometimes they are also called silky desert mice, highland desert mice or silky-footed mice. The closest living relatives are probably the chaco mice (Anda

The genus is found in the Eastern Atlantic Ocean from southwestern Europe to South Africa and into the southwestern Indian Ocean.

Alepes is a genus containing five extant species of tropical marine fishes in the jack family, Carangidae. They are commonly known as scads, a term applied to many genera of carangid fishes. Their body form, however, differs from these other scads by being much more ovate in shape, more similar to the larger jacks taken as game fish, although scads are generally much smaller. They are found in coastal waters throughout the Indo-West Pacific region.

Prosopium is a genus of freshwater whitefishes found in North America and parts of eastern Russia. It contains three fairly widespread species: the round whitefish, the pygmy whitefish, and the mountain whitefish. The remaining species, the Bonneville cisco, the Bonneville whitefish, and the Bear Lake whitefish are endemic to Bear Lake.

Philoria is a genus of frogs native to eastern and southern Australia. These frogs are all confined to mountain areas, with 7 species occurring in the mountains of northern New South Wales and southern Queensland. One species occurs in Victoria. All species are listed as endangered, except the Baw Baw frog, which is listed as critically endangered. They are small to medium-sized frogs that live in water saturated sites, such as sphagnum bogs and seepages on rocky slopes. The eggs are laid in foam nests hidden from light. The tadpoles remain within the nest and live entirely on the yolk.

Balaena is a genus of cetacean (whale) in the family Balaenidae. Balaena is considered a monotypic genus, as it has only a single extant species, the bowhead whale (B. mysticetus). It was named in 1758 by Linnaeus, who at the time considered all of the right whales (and the bowhead) as a single species. Historically, both the family Balaenidae and genus Balaena were known by the common name, "right whales", however Balaena are now known as bowhead whales. upright|thumb|left|Holotype of Balaena montalionis Throughout history, the family Balaenidae has been the subject of great taxonomic debate

Jasus is a genus of spiny lobsters which live in the oceans of the Southern Hemisphere. They have two distinct "horns" projecting from the front of the carapace, but lack the stridulating organs present in almost all other genera of spiny lobsters. Like all spiny lobsters, they lack claws, and have long stout antennae which are quite flexible.

Citharichthys is a genus of flatfish in the large-tooth flounder family, Paralichthyidae. They have both eyes on the left sides of their heads. They are native to the oceans around the Americas, with a single species, C. stampflii off the West African coast. Most are found in relatively shallow depths, but the genus also includes species found in deep water (down to at least ) and species that enter fresh water.

Zapodidae, the jumping mice, is a family of mouse-like rodents in North America and China.

Ailuropodinae is a subfamily of Ursidae that contains only one extant species, the giant panda (Ailuropoda melanoleuca) of China. The fossil record of this group has shown that various species of pandas were more widespread across the Holarctic, with species found in places such as Europe, much of Asia, North America and even Africa. The earliest pandas were not unlike other modern bear species in that they had an omnivorous diet but by around 2.4 million years ago, pandas had evolved to be more herbivorous. The giant panda (Ailuropoda) belongs to the order of Carnivora, this means that the m

Symbolophorus is a genus of lanternfishes. It feeds on various small forms of sea life, in particular fish. Some species in this genus are known to exhibit the Stylophthalmine trait in their larval form. Symbolophorus grows slowly, and shows clear seasonal growth patterns that can be seen in its ear bones which records temperature change in the ocean’s environment.

Euleptorhamphus is a genus of halfbeaks (family Hemiramphidae) in the order Beloniformes.

Bovoidea is a superfamily of pecoran ruminants containing the Bovidae and Moschidae. The Bovoidea today is defined in part by very specific dental and anatomical traits, and genetic research indicates that the Moschidae is the sister taxon to the Bovidae.

Nicoletiidae is a family of primitive insects belonging to the order Zygentoma. These insects live primarily underground, under detritus, or in caves. A few species are recorded as commensals inside nests of social insects, such as the species Allotrichotriura saevissima which lives inside fire ant nests. Nicoletiids lack eyes and they lack pigmentation. They have long antennae and terminal abdominal filaments. Coletinia, a genus of this family, range in size between 10 and 15mm, and may have yellowish pigmentation but most species are transparent.

Physiculus is a genus of morid cods.

Maurolicus is an oceanic ray-finned fish genus which belongs in the marine hatchetfish family Sternoptychidae. They are commonly known as pearlsides, but the brilliant pearlside is the related Argyripnus iridescens. Occasionally, "bristle-mouth fishes" is used as a common name, but that usually refers to the genus Argyripnus or the family Gonostomatidae.

Bolinus is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails.

Ateleopus is a genus of ray-finned fish in the jellynose family Ateleopodidae. It is the type genus of its family, and the order Ateleopodiformes. For some time, it was known as Podateles, because Ateleopus had been used to replace the frog genus name Atelopus, which was deemed to be a spelling error. This was mistaken, however, and the fish and frog genera reverted to their original names.
