General features and special adaptations
The average burden of the family cat-o’-nine-tails varies from 2.7 to 4.5 kg ( 6 to 10 pounds ), although, among nonpedigreed cats, weights up to 12.7 kg ( 28 pounds ) are not uncommon. average lengths are 71.1 cm ( 28 inches ) for males and 50.8 centimeter ( 20 inches ) for females. In keeping with a carnivorous habit, the caterpillar has a bare gut ; the small intestine is lone about three times the length of the body .black cat A black guy ( Felis catus ) arching its back .AdstockRF
The skin of the cat-o’-nine-tails, composed of dermis and epidermis, regenerates and fights off infection promptly. Tiny erector muscles, attached to hair follicles, enable the big cat to bristle all over. frankincense, although the vomit is a relatively humble animal, it can frighten enemies by arching its back, bristle, and hiss.
Coordination and musculature
Cats are among the most highly specialized of the flesh-eating mammals. Their brains are big and well developed. Cats are digitigrade ; that is, they walk on their toes. Unlike the andiron and sawhorse, the computerized tomography walks or runs by moving first the front and back legs on one side, then the front and back legs on the other english ; lone the camel and the giraffe affect in a similar way. The cat ’ randomness body has bang-up elasticity. Because the vertebra of the spinal anesthesia column are held together by muscles rather than by ligaments, as in humans, the big cat can elongate or contract its back, wind it up, or oscillate it along the vertebral line. The construction of the shoulder joints permits the computerized tomography to turn its foreleg in about any direction. Cats are powerfully built animals and are therefore well coordinated that they about constantly land on their feet if they fall or are dropped.
The cat-o’-nine-tails ’ s teeth are adapted to three functions : stab ( canines ), anchoring ( canines ), and cutting ( molars ). Cats have no flat-crowned suppression teeth and consequently can not chew their food ; rather, they cut it up. Except for the canines and molars, the guy ’ randomness teeth are more or less nonfunctional ; most of the impudence teeth do not even meet when the mouth is closed. The dental formula in all cats, for either side of both amphetamine and lower jaw, is incisors 3/3, canines 1/1, premolars 3/2, and molars 1/1. The entire number of teeth is 16 in the upper berth jaw and 14 in the lower. primary, or milk, tooth act 24 ; these are replaced by the permanent tooth at about five months. Each one-half of the chew the fat is hinged to the skull by a cross roller that fits tightly into a trough on the bottom of the skull, making grinding movements impossible even if the cat had teeth suitable for grinding.
There is a noteworthy mechanism for retracting the big cat ’ sulfur claw when they are not in manipulation. The hook is retracted or extended by pivoting the end bone of the toe, which bears the claw, over the peak of the next bone. The action that unsheathes the claw besides spreads the toes wide, making the animal foot more than twice a broad as it normally is and converting it into a truly formidable weapon. This claw-sheathing mechanism is present in all species of the cat family except the cheetah. Although there are no boldness endings in the pinpoint itself, lineage capillaries are show in the inner share.
Cats are broadly nocturnal in habit. The retina of the cat-o’-nine-tails ’ mho eye is made supernumerary sensitive to lightly by a level of guanine, which causes the eye to shine at night in a impregnable light. The eye themselves, big with pupils that expand or compress to mere slits according to the concentration of light, do not distinguish colours clearly. Cats have a third eyelid, or nictitating membrane, normally called the haw. Its appearance is used frequently as an indicator of the big cat ’ s general submit of health .tapetum lucidum The tapetum lucidum, a reflective level behind the retina, increases the amount of fall for night vision in many nocturnal vertebrates. It reflects light outward and thereby allows a second luck for ocular pigments to absorb very low-intensity light .© MegaV0lt—iStock/Getty Images The cat-o’-nine-tails ’ s smell of smell, peculiarly well developed in the adult, is crucial to its evaluation of food, so that a cat whose nasal passages become clogged as a result of illness may appear to lose its appetite completely. Cats can distinguish the smell of nitrogenous substances ( for example, fish ) particularly keenly. The sense of touch is acuate in cats. The eyebrows, whiskers, hairs of the cheek, and fine tufts of hair on the ears are all highly sensitive to vibratory foreplay. The functions of the whiskers ( whisker ) are alone partially understand ; however, it is known that, if they are cut off, the kat is temporarily incapacitated. The toes and paws, ampere well as the gratuity of the nose, are besides very sensitive to touch. Cats besides have an acute accent feel of hearing. Their ears contain about 30 muscles ( compared with 6 in humans ) ; as a consequence, they can turn them many times more quickly in the direction of a sound than can a dog. The ears of cats are receptive to supersonic frequencies up to 85,000 vibrations per second, greatly exceeding the earshot capabilities of dogs, which register 35,000 vibrations per second gear.
