What can be mouse-eared, long-eared or whiskered?
"a lot of research to be carried out to resolve the phylogenetic relationships in the genus ""Plecotus"". Ethiopian big-eared bat The Ethiopian big-eared bat or Ethiopian long-eared bat (""Plecotus balensis"") is a recently described species of long-eared bat in the family Vespertilionidae. The Ethiopian big-eared bat is a typical medium-size representative of the genus ""Plecotus"" ""sensu stricto"" which differs from the widespread Palearctic species grey long-eared bat by its smaller overall size, having a small head, short snout, dark-brownish fur and an absence of any yellow tinges to the fur.

"include the catfish, carp, goatfish, hagfish, sturgeon, zebrafish and some species of shark. The Pimelodidae are a family of catfishes (order Siluriformes) commonly known as the long-whiskered catfishes. Anurognathid pterosaurs have a rugose (wrinkled) jaw texture that has been interpreted as the attachment sites for vibrissae, though actual vibrissae have not been recorded. Whiskers Whiskers or vibrissae (; singular: vibrissa; ) are a type of mammalian hair that are typically characterised, anatomically, by their long length, large and well-innervated hair follicle, and by having an identifiable representation in the somatosensory cortex of the brain. They are specialised for tactile sensing"
"these whiskers is not random: they form an ordered grid of arcs (columns) and rows, with shorter whiskers at the front and longer whiskers at the rear (see images). In the mouse, gerbil, hamster, rat, guinea pig, rabbit, and cat, each individual follicle is innervated by 100–200 primary afferent nerve cells. These cells serve an even larger number of mechanoreceptors of at least eight distinct types. Accordingly, even small deflections of the vibrissal hair can evoke a sensory response in the animal. Rats and mice typically have approximately 30 macrovibrissae on each side of the face, with whisker lengths up"
"Long-eared flying mouse The long-eared flying mouse (""Idiurus macrotis""), or long-eared scaly-tailed flying squirrel, is a species of flying mouse from western and central Africa. It is not actually a :squirrel, nor a :mouse, though it is a rodent. Not much is known about them because they are very hard to keep alive in captivity. To achieve gliding flight, it uses two membranes (patagia) which fold up when not in use. When the limbs are stretched wide in a star-shape, the membranes become taut and allow the rodent to glide from tree to tree. Being arboreal, ""Idiurus"" spends all of"

Whiskered auklets sent through a maze of tunnels with their feathers taped back bumped their heads more than twice as often as they did when their feathers were free, indicating they use their feathers in a similar way to cats. Other birds that have obvious ""whiskers"" are flycatchers, swallows, nightjars, whip-poor-wills, the kakapo and the long-whiskered owlet (""Xenoglaux loweryi""). Some fish have slender, pendulous tactile organs near the mouth. These are often referred to as ""whiskers"", although they are more correctly termed barbels. Fish that have barbels"
"Whiskers Whiskers or vibrissae (; singular: vibrissa; ) are a type of mammalian hair that are typically characterised, anatomically, by their long length, large and well-innervated hair follicle, and by having an identifiable representation in the somatosensory cortex of the brain. They are specialised for tactile sensing (other types of hair operate as more crude tactile sensors). Vibrissae grow in various places on most mammals, including all primates except humans. In medicine, the term vibrissae also refers to the thick hairs found inside human nostrils. Vibrissae (derived from the Latin ""vibrio"" meaning to vibrate) typically grow in groups in different"

Most are short-haired, but some are long-haired. The brow should be heavy and the eyes should have a triangular shape. Eyes are blue when kittens, then change to green or gold when several months old. Tails can be non-existent (rumpy), or 2-4 inches (5–10 cm) (desired – TICA required), or long tails (StoneIsland Pixie was a long-tail). The head is pear shaped. The head is considered to be the most important"
"Long-eared jerboa The long-eared jerboa (""Euchoreutes naso"") is a nocturnal mouse-like rodent with a long tail, long hind legs for jumping, and exceptionally large ears. It is distinct enough that authorities consider it to be the only member of both its genus, Euchoreutes, and subfamily, Euchoreutinae. Long-eared jerboas are found in the Palearctic ecozone. The specific palearctic ecozone areas they are found in are southernmost Mongolia to the Takla-Makan Desert, Mengxin, Aerijin Mountain, and Qing-Zang Plateau regions of north western China. Long-eared jerboas in most cases are nocturnal, The long-eared jerboa's fur according to the book ""100 animals to see"
"Whiskered screech owl The whiskered screech owl (""Megascops trichopsis"") is a small screech owl found in North and Central America. Adults occur in 2 color morphs, in either brown or dark grey plumage. They have a round head with ear tufts, yellow eyes and a yellowish bill. The bird looks very similar to a western screech owl, but has heavier barring on the breast, and is slightly smaller in size. The whiskered screech owl's range extends from southeasternmost Arizona (the Madrean sky islands region) in the United States, southwards through Mexico, Guatemala, El Salvador, Honduras, to north central Nicaragua.

"Long-whiskered owlet The long-whiskered owlet (""Xenoglaux loweryi"") is a tiny owl that is endemic to a small area in the Andean mountains in Amazonas and San Martín in northern Peru. It is restricted to cloud forests with dense undergrowth and epiphytes at about above sea level. The long-whiskered owlet is mainly brown with a whitish belly and eyebrow. The large eyes are orange-brown. Although it has no ear tufts, this small owl's facial feathers extend out past its head, making it appear to have long tufts. The name of its monotypic genus Xenoglaux means ""strange owl"" and—among others—refers to these"

"The frequency of foveal whisking is high, ranging between 15 and 25 Hz, and rats can readily switch between foveal and exploratory whisking. Many land and marine mammals possess facial vibrissae (derived from the Latin ""vibrio"" meaning to vibrate). For example, rats and hamsters, have an arrangement of cranial (of the skull) vibrissae that includes the supraorbital (above the eyes), genal (of the cheeks), and mystacial (where a moustache would be) vibrissae, as well as mandibular (of the jaw) vibrissae under the snout. Mystacial vibrissae are generally described as being further divided into two sub-groups: the large macrovibrissae that protrude"

These mice also have a large infraorbital foramen.

The upper part of the body is brown, sometimes with a yellow or red tinge; the under-parts range from white to cream coloured. It has a prehensile tail which is usually bicoloured and furless at the tip. The mouse's rather broad feet are adapted specifically for climbing, with a somewhat opposable, large outermost toe, allowing it to grip stems with each hindfoot and its tail, thus freeing the"

The songs are similar to that of the northern mockingbird but notes do not end as abruptly; its voice is regarded as more pleasant. The curve-billed can utter songs consecutively two or three times, the length spanning from 2 to 15 seconds. Some phrases are nasal and buzzy; its large vocabulary enables it to conjure successive songs that are usually different from one another. As a mimid it is capable of mimicking several species, including scissor-tailed flycatcher, northern cardinal, pyrrhuloxia and, in"

""Phyllotis xanthopygus"" is a predominantly greyish brown/sand-colored New World mouse that reaches around 55g in its adulthood (relatively large for its genus).
