Dewclaws
A dewclaw is a digit – vestigial in some animals – on the foot of many mammals, birds, and reptiles (including some extinct orders, like certain theropods). It commonly grows higher on the leg than the rest of the foot, such that in digitigrade or unguligrade species, it does not make contact with the ground when the animal is standing. The name refers to the dewclaw's alleged tendency to brush dew away from grass.Danziger, D., & McCrum, M. (2008). ''The Thingummy: A book about those everyday objects you just can't name''. London: Doubleday. On dogs and cats, the dewclaws are on the inside of the front legs, similarly to a human's thumb, which shares evolutionary homology. Although many animals have dewclaws, other similar species do not, such as horses, giraffes and the African wild dog. Dogs Dogs almost always have dewclaws on the inside of the front legs and occasionally also on the hind legs. Unlike front dewclaws, rear dewclaws tend to have little bone or muscle str ...

Unguligrade
Ungulates ( ) are members of the diverse clade Euungulata ("true ungulates"), which primarily consists of large mammals with Hoof, hooves. Once part of the clade "Ungulata" along with the clade Paenungulata, "Ungulata" has since been determined to be a polyphyletic and thereby invalid clade based on molecular data. As a result, true ungulates had since been reclassified to the newer clade Euungulata in 2001 within the clade Laurasiatheria while Paenungulata has been reclassified to a distant clade Afrotheria. Living ungulates are divided into two orders: Perissodactyla including Equidae, equines, rhinoceroses, and tapirs; and Artiodactyla including Bos, cattle, antelope, Sus (genus), pigs, giraffes, camels, Ovis, sheep, deer, and Hippopotamidae, hippopotamuses, among others. Cetaceans such as Whale, whales, Dolphin, dolphins, and Porpoise, porpoises are also classified as artiodactyls, although they do not have hooves. Most terrestrial ungulates use the hoofed tips of their toes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Beauceron
The Beauceron () is a herding dog breed originating from the plains of Central France. The Beauceron is also known as Berger de Beauce (, sheepdog from Beauce) or Bas Rouge (, red-stockings). Description Appearance This breed stands in height and weighs The Beauceron has a hard outer coat and a woolly undercoat that grows thick in cold weather, especially if the dog sleeps outdoors. Its standard colouring is black and tan (the latter colour referred to in French as ''rouge ecureuil'', squirrel-red) or, less frequently, grey, black and tan called harlequin. Other colours, such as the once prevalent tawny, grey or grey/black, are now banned by the breed standard. The harlequin coats should have more black than gray with no white. In the black and tan dogs the tan markings should appear in two dots above the eyes, on the sides of the muzzle, fading off to the cheeks, but do not reach the underside of the ears. Also on the throat, under the tail and on the legs and the chest. Tan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Paw And Pads
A paw is the soft foot-like part of a mammal, generally a quadruped, that has claws. Common characteristics The paw is characterised by thin, pigmented, keratinised, hairless epidermis covering subcutaneous collagenous and adipose tissue, which make up the pads. These pads act as a cushion for the load-bearing limbs of the animal. The paw consists of the large, heart-shaped metacarpal or palmar pad (forelimb) or metatarsal or plantar pad (rear limb), and generally four load-bearing digital pads, although there can be five or six toes in the case of domestic cats and bears (including giant panda). A carpal pad is also found on the forelimb which is used for additional traction when stopping or descending a slope in digitigrade species. Additional dewclaws can also be present. The paw also includes a horn-like, beak shaped claw on each digit. Though usually hairless, certain animals do have fur on the soles of their paws. An example is the red panda, whose furry soles help i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
African Wild Dog
The African wild dog (''Lycaon pictus''), also called painted dog and Cape hunting dog, is a wild canine native to sub-Saharan Africa. It is the largest wild canine in Africa, and the only extant member of the genus '' Lycaon'', which is distinguished from ''Canis'' by dentition highly specialised for a hypercarnivorous diet and by a lack of dewclaws. It is estimated that there are around 6,600 adults (including 1,400 mature individuals) living in 39 subpopulations, all threatened by habitat fragmentation, human persecution and outbreaks of disease. As the largest subpopulation probably consists of fewer than 250 individuals, the African wild dog has been listed as endangered on the IUCN Red List since 1990. The African wild dog is a specialized hunter of terrestrial ungulates, mostly hunting at dawn and dusk, but also displays diurnal activity. It captures its prey by using stamina and cooperative hunting to exhaust them. Its natural competitors are lions and spotted hyenas ...

Lion
The lion (''Panthera leo'') is a large Felidae, cat of the genus ''Panthera'', native to Sub-Saharan Africa and India. It has a muscular, broad-chested body (biology), body; a short, rounded head; round ears; and a dark, hairy tuft at the tip of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on medium-sized and large ungulates. The lion is an apex predator, apex and keystone predator. The lion inhabits grasslands, savannahs, and shrublands. It is usually more diurnality, diurnal than other wild cats, but when persecuted, it adapts to being active nocturnality, at night and crepuscular, at twilight. During the Neolithic period, the lion ranged throughout Africa and Eurasia, from Southeast Europe to India, but it has been reduced to fr ...

Felidae
Felidae ( ) is the Family (biology), family of mammals in the Order (biology), order Carnivora colloquially referred to as cats. A member of this family is also called a felid ( ). The 41 extant taxon, extant Felidae species exhibit the greatest diversity in fur patterns of all terrestrial carnivores. Cats have retractile claws, slender muscular bodies and strong flexible forelimbs. Their teeth and facial muscles allow for a powerful bite. They are all obligate carnivores, and most are solitary predators ambushing or stalking their prey. Wild cats occur in Africa, Europe, Asia and the Americas. Some wild cat species are adapted to forest and savanna habitats, some to arid environments, and a few also to wetlands and mountainous terrain. Their activity patterns range from nocturnal and crepuscular to Diurnality, diurnal, depending on their preferred prey species. Reginald Innes Pocock divided the extant Felidae into three subfamilies: the Pantherinae, the Felinae and the Acin ...

Portuguese Water Dog
The Portuguese Water Dog originated from the Algarve, Algarve region of Portugal. From there the breed expanded to all around Portugal's coast, where they were taught to herd fish into fishermen's nets, retrieve lost tackle or broken nets, and act as couriers from ship to ship, or ship to shore. Portuguese Water Dogs rode in fishing trawlers as they worked their way from the Atlantic waters of Portugal to the waters off the coast of Iceland fishing for cod. In Portuguese language, Portuguese, the breed is called (; literally 'dog of water'). In Portugal, the dog is also known as the Algarvian Water Dog (), or Portuguese Fishing Dog (). is the name given to the wavy-haired variety, and is the name for the curly-coated variety. The Portuguese Water Dog is a fairly rare breed; only 36 Portuguese Water Dogs were entered for Britain's Crufts competition in 2013. Though some breeders claim they are a hypoallergenic dog breed, there is no scientific evidence to support the claim ...

Veterinarian
A veterinarian (vet) or veterinary surgeon is a medical professional who practices veterinary medicine. They manage a wide range of health conditions and injuries in non-human animals. Along with this, veterinarians also play a role in animal reproduction, health management, Animal Conservation, conservation, husbandry and breeding and preventive medicine like animal nutrition, nutrition, vaccination and parasitic control as well as biosecurity and zoonotic disease surveillance and prevention. Description In many countries, the local nomenclature for a veterinarian is a regulated and protected term, meaning that members of the public without the prerequisite qualifications and/or license are not able to use the title. This title is selective in order to produce the most knowledgeable veterinarians that pass these qualifications. In many cases, the activities that may be undertaken by a veterinarian (such as treatment of illness or surgery in animals) are restricted only to thos ...

Bitterant
A bitterant (or bittering agent) is a chemical that is added to a product to make it olfaction, smell or taste Taste#Bitterness, bitter. Bitterants are commonly used as aversive agents to discourage the inhalation or ingestion of toxic substances. Examples of use *The addition of a bitterant to ethanol Denatured alcohol, denatures the product. *Bitterants are used in antifreeze to prevent pet and child poisonings. It is required by law in some places (France, Oregon, etc.). *Gas dusters often use a bitterant to discourage inhalant abuse, although this can cause problems for legitimate users. The bitterant not only leaves a bitter flavor in the air, but also leaves a bitter residue on objects, like screens and keyboards, that may transfer to hands and cause problems (such as when eating). *Nintendo game card#Nintendo Switch, Game cartridges for the Nintendo Switch are coated with denatonium as a safety feature to deter small children from Pica (disorder), ingesting them. *Some but ...

Elizabethan Collar
An Elizabethan collar, E collar, buster collar, pet ruff or pet cone (sometimes humorously called a treat funnel, lamp-shade, radar dish, dog-saver, collar cone, or cone of shame) is a protective medical device worn by an animal, usually a cat or dog. Shaped like a truncated cone, its purpose is to prevent the animal from biting or Wound licking, licking at its body or scratching at its head or neck while wounds or injuries Wound healing, heal. The collars are named from the Ruff (clothing), ruffs worn in the Elizabethan era. The device is generally attached to the pet's usual Collar (animal), collar with strings or tabs passed through holes punched in the sides of the plastic. The neck of the collar should be short enough to let the animal eat and drink. Although most pets adjust to them quite well, others will not eat or drink with the collar in place and the collar is temporarily removed for meals. While purpose-made collars can be purchased from veterinarians or Pet store, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Phalanx Bones
The phalanges (: phalanx ) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones. Structure The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and big toe, which possess only two. The middle and far phalanges of the fifth toes are often fused together (symphalangism). The phalanges of the hand are commonly known as the finger bones. The phalanges of the foot differ from the hand in that they are often shorter and more compressed, especially in the proximal phalanges, those closest to the torso. A phalanx is named according to whether it is proximal, middle, or distal and its associated finger or toe. The proximal phalang ...

LMBR1
Limb region 1 protein homolog is a protein that in humans is encoded by the ''LMBR1'' gene. This gene encodes a member of the LMBR1-like membrane protein family. Another member of this protein family has been shown to be a lipocalin transmembrane receptor. A highly conserved, cis-acting regulatory module for the sonic hedgehog (protein) gene is located within an intron of this gene. Consequently, disruption of this genic region can alter sonic hedgehog expression and affect limb patterning, but if this gene functions directly in limb development is unknown. Mutations and chromosomal deletions and rearrangements in this genic region are associated with acheiropody and preaxial polydactyly Polydactyly is a birth defect that results in extra fingers or toes. The hands are more commonly involved than the feet. Extra fingers may be painful, affect self-esteem, or result in clumsiness. It is associated with at least 39 genetic mut ..., which likely result from altered sonic hed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
