The hispid hocicudo (Oxymycterus hispidus) is a rodent species from South America. It is found in Argentina and Brazil, in the Atlantic Forest. [1]
The rodent subfamily Sigmodontinae includes New World rats and mice, with at least 376 species. Many authorities include the Neotominae and Tylomyinae as part of a larger definition of Sigmodontinae. When those genera are included, the species count numbers at least 508. Their distribution includes much of the New World, but the genera are predominantly South American, such as brucies. They invaded South America from Central America as part of the Great American Interchange near the end of the Miocene, about 5 million years ago. Sigmodontines proceeded to diversify explosively in the formerly isolated continent. They inhabit many of the same ecological niches that the Murinae occupy in the Old World.
Oxymycterus is a genus of rat-like rodents commonly known as hocicudos. They are endemic to South America. As of April 2019, the genus contains the following 16 species:
Ferreira's spiny tree-rat is a spiny rat species found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname and Venezuela. The etymology of the species name corresponds to the Latin word hispidus meaning bristly.
The Caparaó hocicudo is a rodent species from South America. It is endemic to Brazil where it is found in the Pico da Bandeira mountain range.
The long-nosed hocicudo is a South American rodent species found in southeastern Brazil and Uruguay.
Robert's hocicudo is a rodent species from South America. It is found in Brazil and Paraguay.
The red hocicudo is a rodent species from South America. It is found in Argentina, Brazil and Uruguay.
The bristly catshark is a cat shark of the family Scyliorhinidae, found from southeastern India and the Andaman Islands, between latitudes 15° N and 5° N, at depths between 200 and 300 m. Its length usually ranges from around 20–26 cm, and it is regarded as the smallest catshark of Bythaelurus.
Vesper mice are rodents belonging to the genus Calomys. They are widely distributed in South America. Some species are notable as the vectors of Argentinian hemorrhagic fever and Bolivian hemorrhagic fever.
The hispid pocket mouse is a large pocket mouse native to the Great Plains region of North America. It is a member of the genus Chaetodipus.
The Argentine hocicudo is a species of rodent in the family Cricetidae. It is found only in northern Argentina in yungas habitat. The exact population is unknown as only three specimens have been collected and threats may be deforestation and overgrazing although the exact effects are unknown. Some authorities consider it to be conspecific with Oxymycterus paramensis, while others consider it distinct.
The spy hocicudo is a species of rodent in the family Cricetidae. It is found only in Paraguay.
Oxymycterus hucucha, also known as the Quechuan hocicudo, is a species of rodent in the genus Oxymycterus of family Cricetidae from South America. It is found only in a small region of the Andes in central Bolivia, where it lives in cloud forest at altitudes from 2600 to 3000 m.
The Incan hocicudo is a species of rodent in the family Cricetidae. It is found in Bolivia and Peru.
The Paramo hocicudo is a species of rodent in the family Cricetidae. It is found in Argentina, Bolivia, and Peru. The Argentine hocicudo is sometimes considered conspecific.
The Angel Island chuckwalla, also known as the spiny chuckwalla, is a species of chuckwalla lizard belonging to the family Iguanidae endemic to Isla Ángel de la Guarda in the Gulf of California. The species was transported to other islands by a tribe of the Seri as a potential food source.
Ontocetus is an extinct genus of walrus, an aquatic carnivoran of the family Odobenidae, endemic to coastal regions of the southern North Sea and the southeastern coastal regions of the U.S. during the Miocene-Pleistocene. It lived from 13.6 mya—300,000 years ago, existing for approximately 13.3 million years.
Cook's hocicudo is a species of rodent in the family Cricetidae. It is found only in southern Uruguay, where it lives in wetlands, moist grasslands and scrub. The specifies is named after American zoologist Joseph "José" A. Cook.
The quaestor hocicudo is a species of rodent in the family Cricetidae. It is found in southeastern Brazil and northeastern Argentina, where it lives in forest and moist and dry scrub.
Albicetus is a genus of stem-sperm whales that lived during the Miocene Epoch, around 15 million years ago, and was discovered in Santa Barbara, California in 1909. It was categorized for decades as belonging to a group of extinct walruses erroneously thought to be sperm whales. It was named Albicetus, meaning "white whale", is a reference to the leviathan in Herman Melville's classic 1851 novel Moby-Dick.
