Neusticomys Mussoi
Musso's fish-eating rat (''Neusticomys mussoi'') is a species of rodent in the family Cricetidae endemic to western Venezuela, where it has been found at altitudes of 1000 to 1200 m. It is semiaquatic In biology, semiaquatic can refer to various types of animals that spend part of their time in water, or plants that naturally grow partially submerged in water.

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Cricetidae
The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, muskrats, and New World rats and mice. At almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia. Characteristics The cricetids are small mammals, ranging from just in length and in weight in the New World pygmy mouse up to and in the muskrat. The length of their tails varies greatly in relation to their bodies, and they may be either furred or sparsely haired. The fur of most species is brownish in colour, often with a white underbelly, but many other patterns exist, especially in the cricetine and arvicoline subfamilies. Like the Old World mice, cricetids are adapted to a wide range of habitats, from the high Arctic to tropical rainforests and hot deserts. Some are arboreal, with long balancing tails and other adaptations for climbing, while others are semiaquatic, with w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venezuela
Venezuela (; ), officially the Bolivarian Republic of Venezuela ( es, link=no, República Bolivariana de Venezuela), is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in the Caribbean Sea. It has a territorial extension of , and its population was estimated at 29 million in 2022. The capital and largest urban agglomeration is the city of Caracas. The continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. The Venezuelan government maintains a claim against Guyana to Guayana Esequiba. Venezuela is a federal presidential republic consisting of 23 states, the Capital District and federal dependencies covering Venezuela's offshore islands. Venezuela is among the most urbanized countries in Latin America; the vast majority of Venezuelans live in the cities of the n ...

Semiaquatic
In biology, semiaquatic can refer to various types of animals that spend part of their time in water, or plants that naturally grow partially submerged in water. Examples are given below. Semiaquatic animals Semiaquatic animals include: * Vertebrates ** Amphibious fish; also several types of normally fully aquatic fish such as the grunion and plainfin midshipman that spawn in the intertidal zone ** Some amphibians such as newts and salamanders, and some frogs such as fire-bellied toads and wood frogs. ** Some reptiles such as crocodilians, turtles, water snakes and marine iguanas. ** Penguins. ** Some rodents such as beavers, muskrats and capybaras. **Some insectivorous mammals such as desmans, water shrews and platypuses. ** Some carnivoran mammals, including seals, polar bears and otters. ** Hippopotamuses. * Semiterrestrial echinoderms of the intertidal zone, such as the "cliff-clinging" sea urchin ''Colobocentrotus atratus'' and the starfish '' Pisaster ochraceus'' ...

Neusticomys
''Neusticomys'' is a genus of semiaquatic, animalivorous South American rodents in the family Cricetidae. The term ''Neusticomys'' derives from the two ancient greek words (), meaning "able to swim", and (), meaning "mouse, rat". ''N. monticolous'' and ''N. vossi'' primarily inhabit montante regions of west Columbia and eastern Ecuador, with the former noted to occur in the Andean Cordillera and the Occidental mountain range at elevations of 1,800-3,750 meters. The rest inhabit tropical lowland forests primarily in the northern and eastern regions of the Amazon rainforest, whereas ''N. peruviensis'' is an endemic species to Peru. This genus contains the following seven species: * Ferreira's fish-eating rat (''Neusticomys ferreirai'') — Percequillo, Carmignotto & Silva, 2005 * Montane fish-eating rat (''N. monticolus'') — Anthony, 1921 * Musso's fish-eating rat (''N. mussoi'') — Ochoa G. & Soriano, 1991 * Oyapock's fish-eating rat (''N. oyapocki'') — (Dubost & Pette ...

Mammals Described In 1991
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together ...
