Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Sorex
The genus ''Sorex'' includes many of the common shrews of Eurasia and North America, and contains at least 142 known species and subspecies. Members of this genus, known as long-tailed shrews, are the only members of the tribe Soricini of the subfamily ''Soricinae'' (red-toothed shrews). They have 32 teeth. These animals have long, pointed snouts, small ears, which are often not visible, and scent glands located on the sides of their bodies. As their eyesight is generally poor, they rely on hearing and smell to locate their prey, mainly insects. Some species also use echolocation. Distinguishing between species without examining the dental pattern is often difficult. In some species, a female shrew and her dependent young form "caravans", in which each shrew grasps the rear of the shrew in front, when changing location. Species * Genus ''Sorex'' – most basal of the genera ** Kashmir pygmy shrew (''S. planiceps'') – India and Pakistan ** Tibetan shrew (''S. thibetanus'') â ...

Poliocitellus
Franklin's ground squirrel (''Poliocitellus franklinii'') is a species of squirrel native to North America, and the only member of the genus ''Poliocitellus''. Due to the destruction of prairie, the populations of Franklin's ground squirrel have dwindled, approaching levels of concern. Its decline in the eastern portion of its range is mostly attributed to habitat fragmentation. Taxonomy Franklin's ground squirrel was first described by Joseph Sabine in 1822, who named it in honor of the British Arctic explorer Sir John Franklin. It was formerly placed in the large ground squirrel genus ''Spermophilus'', in its own subgenus, ''Poliocitellus'', but since DNA sequencing of the cytochrome ''b'' gene has shown ''Spermophilus'' to be paraphyletic it is now placed in its own genus. Franklin's ground squirrel is suggested to be sister to a clade containing not only the Mohave, round-tailed, spotted, and Perote ground squirrels (genus ''Xerospermophilus''), but the prairie dogs as ...

Peromyscus
''Peromyscus'' is a genus of rodents. They are commonly referred to as deer mice or deermice, not to be confused with the chevrotain or "mouse deer". They are New World mice only distantly related to the common house and laboratory mouse, ''Mus musculus''. From this relative, ''Peromyscus'' species are distinguished by relatively larger eyes, and also often two-tone coloring, with darker colors over the dorsum (back), and white abdominal and limb hair-coloring. In reference to the coloring, the word ''Peromyscus'' comes from Greek words meaning "booted mouse". They are also accomplished jumpers and runners by comparison to house mice, and their common name of "deer mouse" (coined in 1833) is in reference to this agility. The most common species of deer mice in the continental United States are two closely related species, '' P. maniculatus'' and '' P. leucopus''. In the United States, ''Peromyscus'' is the most populous mammalian genus overall, and has become notorious in the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parascalops
The hairy-tailed mole (''Parascalops breweri''), also known as Brewer's mole, is a medium-sized North American mole. It is the only member of the genus ''Parascalops''. The species epithet ''breweri'' refers to Thomas Mayo Brewer, an American naturalist. Taxonomy Despite inhabiting North America, studies indicate that it is not closely related to the two other North American scalopine moles (''Scalopus'' and ''Scapanus''), but rather to the two Chinese scalopine moles ('' Scapanulus'' and '' Alpiscaptulus''). This indicates that the two Chinese moles likely descend from a migration from North America back into Eurasia, where the scalopine moles originated. Some studies have suggested placing ''Parascalops'', ''Scapanulus'', and ''Alpiscaptulus'' into a single subtribe Parascalopina. Appearance This animal has dark grey fur with lighter underparts, a pointed nose and a short, hairy tail. It is about in length, including a tail, and weighs about . Its front paws are broad ...

Onychomys
Grasshopper mice are rodents of the genus ''Onychomys'', occurring in North America. They feed on insects and other arthropods. Biology The three species in this genus of New World mice are only distantly related to the common house mouse, ''Mus musculus''. They are endemic to the United States and Mexico. The southern grasshopper mouse has around a long body and a tail that is generally long. Its behavior is distinct from other mice. It is a carnivorous rodent, dining on insects (such as grasshoppers), worms, spiders, centipedes, scorpions, snakes, and even other mice. It also stalks its prey in the manner of a cat, sneaking up quietly, and defends its territory by "howling" like a small wolf. The grasshopper mouse is known to be immune to various venoms released by its prey (scorpions, snakes, etc.). Grasshopper mice are nocturnal and avoid exposure to bright light. Ecology Diet Grasshopper mice prey on highly venomous arthropods. One example is centipedes that normally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ondatra
The muskrat (''Ondatra zibethicus'') is a medium-sized semiaquatic rodent native to North America and an introduced species in parts of Europe, Asia, and South America. The muskrat is found in wetlands over a wide range of climates and habitats. It has important effects on the ecology of wetlands, and is a resource of food and fur for humans. Adult muskrats weigh , with a body length of . They are covered with short, thick fur of medium to dark brown color. Their long tails, covered with scales rather than hair, are their main means of propulsion. Muskrats spend most of their time in the water and can swim under water for 12 to 17 minutes. They live in families, consisting of a male and female pair and their young. To protect themselves from the cold and from predators, they build nests that are often burrowed into the bank with an underwater entrance. Muskrats feed mostly on cattail and other aquatic vegetation but also eat small animals. ''Ondatra zibethicus'' is the only s ...
