Query: How tall are zebra?
The Cape mountain zebra differs slightly from the Hartmann's subspecies, being stockier and having longer ears and a larger dewlap. Adults have a shoulder height of 116 to 128  cm, making them the most lightly built subspecies of zebra. There is slight sexual dimorphism with mares having a mass of around 234  kg and stallions weighing around 250–260  kg.
Currently, the world's tallest horse is a Belgian Draft horse named Big Jake, a gelding born in 2000. He stands tall.
"Brontosaurus" was a large, long-necked quadrupedal animal with a long, whip-like tail, and forelimbs that were slightly shorter than its hindlimbs. The largest species, "B. excelsus", weighed up to and measured up to long from head to tail. For comparison, the current largest land animal, the average male African bush elephant is 3.20 m (10.5 ft) tall at the shoulder and has a body mass of 6,000 kg (13,228 lb) or 6.6 short tons.
The black wildebeest or white-tailed gnu ("Connochaetes gnou") is one of the two closely related wildebeest species. It is a member of the genus "Connochaetes" and family Bovidae. It was first described in 1780 by Eberhard August Wilhelm von Zimmermann. The black wildebeest is typically in head-and-body length, and the typical weight is . Males stand about at the shoulder, while the height of the females is . The black wildebeest is characterised by its white, long, horse-like tail. It also has a dark brown to black coat and long, dark-coloured hair between its forelegs and under its belly.
Yellow-footed tortoises are a large species – fifth-largest overall and third-largest mainland species, after the Aldabra giant tortoise ("Aldabrachelys gigantea"), Galapagos giant tortoise ("Chelonoidis nigra"), African spurred tortoise, and Asian forest tortoise. Typical sizes average 40 cm (15.75 in), but much larger specimens are common. The largest know specimen is a female that was 94 cm (37 in) long. They closely resemble the red-footed tortoise, and can sometimes be difficult to tell apart, especially as a preserved specimen, which led to quite a bit of confusion over the names and ranges.
Zeta Muscae, Latinized from ζ Muscae, is a star in the constellation Musca. Its apparent magnitude is 5.74. Located around 326 light-years distant, it is an orange giant of spectral type K0III, a star that has used up its core hydrogen and is cooling and expanding. The star is radiating 64 times the Sun's luminosity.
Medicine Lake has also been confirmed for the presence of zebra mussels. On November 1, 2017, a resident notified the Minnesota DNR regarding a potential zebra muscle on a dock that the resident had pulled from the lake. On November 2, Minnesota DNR staff verified it was a zebra mussel and found two additional zebra mussels on two other docks in the lake. On November 9, 2017, the Minnesota DNR issued a press release publicly confirming that it had found zebra mussels in the lake.
Black wildebeest are sexually dimorphic, with females being smaller in size and more slender than males. The head-and-body length is typically between . Males reach about at the shoulder, while females reach . Males typically weigh and females . A distinguishing feature in both sexes is the tail, which is long and similar to that of a horse. Its bright-white colour gives this animal the vernacular name of "white-tailed gnu", and also distinguishes it from the blue wildebeest, which has a black tail. The length of the tail ranges from .
Zebra mussel and the closely related and ecologically similar quagga mussels are filter-feeding organisms. They remove particles from the water column. The zebra mussels process up to one liter of water per day, per mussel. Some particles are consumed as food, and feces are deposited on the lake floor. Nonfood particles are combined with mucus and other matter and deposited on lake floors as pseudofeces. Since the zebra mussel has become established in Lake Erie, water clarity has increased from 6 inches to up to three feet in some areas. This improved water clarity allows sunlight to penetrate deeper, enabling growth of submerged macrophytes. These plants, when decaying, wash up on shorelines, fouling beaches and cause water quality problems.
A native of western Russia, the zebra mussel most likely made its way to North America through the release of ballast water from cargo ships traveling from the Black Sea to the Great Lakes. After its introduction there, it was carried through the lakes and connected waterways via recreational and commercial traffic. A large part of the zebra mussel's ability to disperse has to do with its travel flexibility. In the larval stage, zebra mussels can float along passively. In the adult stage, zebra mussels can attach themselves to boats very well. Overland dispersal can be achieved, too, because these mussels can survive dry conditions for several days. This was most likely the way that they were introduced to California: agricultural inspection stations have reported finding mussels on the hulls or motor compartments of at least 19 trailered boats arriving into the state. In addition to being able to travel long distances during both immature and mature stages of life, zebra mussels can produce up to several hundred thousand eggs in a single season.
The African bush elephant is the largest and heaviest land animal on Earth, being up to tall at the shoulder and in weight (a male shot in 1974, near Mucusso, southern Angola). On average, males are about tall at the shoulder and in weight, while females are much smaller at about tall at the shoulder and in weight. Elephants attain their maximum stature when they complete the fusion of long-bone epiphyses, occurring in males around the age of 40 and females around the age of 25. Their large size means that they must consume around 50 gallons of water every day in order to stay hydrated.
In English-speaking countries, the height of horses is often stated in units of hands and inches: one hand is equal to . The height is expressed as the number of full hands, followed by a point, then the number of additional inches, and ending with the abbreviation "h" or "hh" (for "hands high"). Thus, a horse described as "15.2 h" is 15 hands plus 2 inches, for a total of in height.
The size of horses varies by breed, but also is influenced by nutrition. Light riding horses usually range in height from and can weigh from . Larger riding horses usually start at about and often are as tall as , weighing from . Heavy or draft horses are usually at least high and can be as tall as high. They can weigh from about .
A male African forest elephant rarely exceeds 2.5 m (8.2 ft) in height, considerably smaller than the bush species which is usually over 3 m (9.8 ft) and sometimes almost 4 m (13.1 ft) tall. "L. cyclotis" reportedly weighs around , with the largest specimens attaining . Pygmy elephants of the Congo Basin, presumed to be a subgroup of "L. cyclotis", have reportedly weighed as little as as adults.
The largest Indian elephant was high at the shoulder. In 1985, two large elephant bulls were spotted for the first time in Bardia National Park, and named "Raja Gaj" and "Kanchha". They roamed the park area together and occasionally visited female herds. "Raja Gaj" stood tall at the shoulder and had a massive body weight. His forehead and domes were more prominent than in other Asian bull elephants. His appearance has been compared to that of a Stegodon and mammoth due to his high bi-domed shaped head.
The European jackal is the largest of the golden jackals, with animals of both sexes measuring 120–125 cm (47–49 in) in total length and 10–13 kg (20–29 lb) in body weight. One adult male in North-Eastern Italy is recorded to have reached 14.9 kg (33 lb). The fur is coarse, and is generally brightly coloured with blackish tones on the back. The thighs, upper legs, ears and forehead are bright reddish chestnut. Jackals in Northern Dalmatia have broader than average skulls, which is thought to result from human induced isolation from other populations, thus resulting in a new morphotype.
With a mass of approximately and a length of 5 centimetres (2.0 in), the bee hummingbird ("Mellisuga helenae") is the world's smallest bird species and the smallest warm-blooded vertebrate. Called the "zunzún" in its native habitat on Cuba, it is lighter than a Canadian or U.S. penny. It is said that it is "more apt to be mistaken for a bee than a bird". The bee hummingbird eats half its total body mass and drinks eight times its total body mass each day. Its nest is 3 cm across.
There has been some research on the freshwater drum's impact on the invasive Zebra mussel in northern lakes and rivers. Zebra mussels are consumed by freshwater drum once they reach a length of , but drum under in length only eat small mussels and reject the larger ones. The fish larger than exhibit less selectivity and consume mussels relative to their availability in lakes. These larger fish are not restricted by their ability to crush the zebra mussels, but they are restricted by the size of the clumps that they can remove. Though the drum do eat zebra mussels, they are not having an impact on the spread of this invasive species. Though they do not control the population of zebra mussels, they do contribute to a high mortality in the zebra mussels.
The Halden is similar to the American Foxhound in appearance although it is smaller. Haldens stand between 17 and 21.5 inches at the shoulder, and weigh approximately 40-55 lbs. They have smooth, very dense coats, hanging ears, and are white with black patches as well as brown shading on the head and legs. They are strong dogs with rectangular bodies and straight, solid backs. The tail is fairly thick, carried low, and hangs down toward the hocks. The skull is slightly domed with a pronounced stop and a straight nosebridge. The cheeks are flat. The ears are pendulous and curled, and the eyes are dark brown and kind. The nose is black. Breeders of Haldens aim for a particular foot shape, with high, tight, long toes and dense fur, for greater stability and warmth as the terrain they hunt through is often snowy and difficult to navigate.
While comparing between various classes of animals, a different unit is used, body length per second for organisms. The fastest organism on earth, relative to body length, is the South Californian mite "Paratarsotomus macropalpis", which has a speed of 322 body lengths per second. The equivalent speed for a human running as fast as this mite would be . This is far in excess of the previous record holder, the Australian tiger beetle, "Cicindela eburneola", the fastest insect in the world relative to body size, which has been recorded at or 171 body lengths per second. The cheetah, the fastest land mammal, scores at only 16 body lengths per second while Anna's hummingbird has the highest known length-specific velocity attained by any vertebrate
In general, Asian elephants are smaller than African elephants and have the highest body point on the head. The tip of their trunk has one finger-like process. Their back is convex or level. Indian elephants reach a shoulder height of between , weigh between , and have 19 pairs of ribs. Their skin color is lighter than of "maximus" with smaller patches of depigmentation, but darker than of "sumatranus". Females are usually smaller than males, and have short or no tusks.
"S. kinghorni" has been known to attain a total length (including tail) up to approximately 7 meters (about 24 feet), with some field measurements claiming to be even longer, making this snake one of Australia's largest and longest snakes, if not, the largest and longest of Australia. This snake is commonly considered arboreal or tree-dwelling, making it one of the world's largest and longest arboreal species of snakes. This snake has an ornate back pattern consisting of browns and tans, with many different natural variations. Its belly is usually white, sometimes with some yellows.
The Grévy's zebra ("Equus grevyi"), also known as the imperial zebra, is the largest living wild equid and the largest and most threatened of the three species of zebra, the other two being the plains zebra and the mountain zebra. Named after Jules Grévy, it is the sole extant member of the subgenus "Dolichohippus". Grévy's zebra is found in Kenya and Ethiopia. Compared with other zebras, it is tall, has large ears, and its stripes are narrower.
Amoria zebra, common name the zebra volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.The length of the shell varies between 25 mm and 55 mm. These shells are solid, glazed, with a short spire. Whorls are usually smooth and glossy. 
Columella is white and shows four strong plaits. The outer lip is thickened and smooth. The pattern of these shells is quite variable, in colour and in the density of the axial lines. The background colour varies from white to fawn or mid-brown, usually with axial brown lines.
The vast majority of the organisms that are natural enemies in Europe are not present in North America. Ecologically similar species do exist, but these species are unlikely to be able to eliminate those mussels already established and will have a limited role in their control.
Crayfish could have a significant impact on the densities of 1- to 5-mm-long zebra mussels. An adult crayfish consumes around 105 zebra mussels every day, or about 6000 mussels in a season. Predation rates are significantly reduced at lower water temperatures.
Fish do not seem to limit the densities of zebra mussels in European lakes. Smallmouth bass are a predator in the zebra mussels' adopted North American Great Lakes habitat.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is N6-(L-1,3-dicarboxypropyl)-L-lysine:NAD+ oxidoreductase (L-lysine-forming). Other names in common use include lysine-2-oxoglutarate reductase, dehydrogenase, saccharopine (nicotinamide adenine dinucleotide, lysine forming), epsilon-N-(L-glutaryl-2)-L-lysine:NAD oxidoreductase (L-lysine, forming), N6-(glutar-2-yl)-L-lysine:NAD oxidoreductase (L-lysine-forming), 6-N-(L-1,3-dicarboxypropyl)-L-lysine:NAD+ oxidoreductase, and (L-lysine-forming). This enzyme participates in lysine biosynthesis and lysine degradation.
