Rhinoceros
2008-08-29 02:09:00
Rhinoceros, often colloquially abbreviated rhino, is the common name used to group five extant species of odd-toed ungulates in the family Rhinocerotidae. Two of these species are native to Africa and three to southern Asia. Three of the five species—the (Javan, Sumatran and Black Rhinoceros)—are critically endangered. The Indian is endangered, with fewer than 2700 individuals remaining in the wild. The White is registered as Vulnerable, with roughly 14,500 remaining in the wild. The rhinoce......
 
Giraffe
2008-06-29 05:00:00
The giraffe (Giraffa camelopardalis) is an African even-toed ungulate mammal, the tallest of all land-living animal species, and the largest ruminant. Males can be 4.8 to 5.5 metres (16 to 18 feet) tall and weigh up to 1,700 kilograms (3,800 pounds). The record-sized bull, shot in Kenya in 1934, was 5.87 m (19.2 ft) tall and weighed approximately 2,000 kg (4,400 lb). Females are generally slightly shorter, and weigh less than the males do. Giraffes can inhabit savannas, grasslands, or open woodl......
 
Bull Shark
2008-06-22 05:00:00
The bull shark, Carcharhinus leucas, also known as the bull whaler, Zambezi shark or informally Zambi in Africa and Nicaragua shark in Nicaragua, is common worldwide in warm, shallow waters along coasts and in rivers. The bull shark is well known for its unpredictable, often aggressive behavior. Many scientists agree that since bull sharks often dwell in shallow waters, they may be more dangerous to humans than any other species of sharks. Unlike most other marine sharks, bull sharks tolerate fr......
 
Box Jellyfish
2008-06-15 05:00:00
Box jellyfish are invertebrates belonging to the class Cubozoa, named for their cube-shaped medusae. The Cubozoans are a categorized separately other types of jellyfish, and are considered more evolved; Scyphozoans. Likewise, the best-known species of box jellyfish, Chironex fleckeri, while sometimes simply called "the Box Jellyfish", is only one species of the category which actually contains about 19 different species. The name sea wasp is also applied to some species of cubozoans, including t......
 
Crocodile
2008-06-08 05:00:00
Crocodiles are among the more biologically complex reptiles despite their prehistoric look. Unlike other reptiles, they have a diaphragm, cerebral cortex and four-chambered heart. Their external morphology on the other hand is a sign of their aquatic and predatory lifestyle. A crocodile’s physical traits allow it to be a successful predator. They have a streamlined body that enables them to swim swiftly. Crocodiles also tuck their feet to their sides while swimming, which makes them faster by ......
 
Black Rhinoceros
2008-06-03 23:01:00
The Black Rhinoceros (Diceros bicornis), also colloquially Black Rhino, is a mammal in the order Perissodactyla, native to the eastern and central areas of Africa including Kenya, Tanzania, Cameroon, South Africa, Namibia and Zimbabwe. Although the Rhino is referred to as black, it is actually more of a grey/brown/white color in appearance. The name of the species was chosen to distinguish it from the White Rhinoceros (Ceratotherium simum). This is misleading, as those two species are not really......
 
Warthog
2008-04-27 16:03:00
Warthogs range in size from 0.9 to 1.5 metres (2.9-4.9 feet) in length and 50 to 150 kg (110-330 pounds) in weight. A warthog is identifiable by the two pairs of tusks protruding from the mouth, which are used as weapons against predators. The upper canine teeth can grow to 9 inches (23 cm), and are of a squashed circle shape in cross section, almost rectangular, being about 1¾ in (4.5 cm) deep and 1 in (2.5 cm) wide. The tusk will curve 90 degrees or more from the root, and the tusk will not l......

The Peregrine Falcon (Falco peregrinus), also known simply as the Peregrine, and historically also as "Duck Hawk" in North America, is a cosmopolitan bird of prey in the family Falconidae. It is a large falcon, about the size of a large crow, with the female being larger than the male, and with a blue-gray back, barred white underside, and a black head and "mustache". About seventeen subspecies are recognized, which vary in appearance and range. It feeds almost exclusively on medium-sized birds,......
 
Polar Bear
2008-04-09 23:37:00
The polar bear (Ursus maritimus) is a bear native to the Arctic. The world's largest land carnivore, an adult male weighs around 300–600 kg (660–1320 lb), while an adult female is about half that size. Although it is closely related to the brown bear, it has evolved to occupy a narrow ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting seals. It feeds almost exclusively on seals, although it is an opport......
 
Komodo Dragon
2008-04-08 23:37:00
In the wild, an adult Komodo dragon usually weighs around 70 kilograms (154 lb), although captive specimens often weigh more. The largest verified wild specimen was 3.13 meters (10 ft 3 in) long and weighed 166 kilograms (365 lb), including undigested food. The Komodo dragon has a tail as long as their body, as well as about 60 frequently-replaced serrated teeth that can measure up to 2.5 centimeters (1 inch) in length. Its saliva is frequently blood-tinged, because its teeth are almost complete......
 
Black Rhino

An adult Black Rhinoceros stands 140–170 cm (57.9–63 inches) high at the shoulder and is 3.3-3.6 m (10.8–11.8 feet) in length.[3] An adult weighs from 800 to 1400 kg (1,760 to 3,080 lb), exceptionally to 1820 kg (4,000 lb), with the females being smaller than the males. Two horns on the skull are made of keratin with the larger front horn typically 50 cm long, exceptionally up to 140 cm. Sometimes, a third smaller horn may develop. These horns are used for defense, intimidation, and diggin......
 
Hippo
2008-04-05 22:25:00
The hippopotamus is recognizable for its barrel-shaped torso, enormous mouth and teeth, hairless body, stubby legs and tremendous size. It is similar in size to the White Rhinoceros; only elephants are consistently larger. Despite its stocky shape and short legs, it can easily outrun a human. Hippos have been clocked at 30 mph (48 km/h) while running short distances, faster than an Olympic sprinter. The hippopotamus is among the most dangerous and aggressive of all animals, and are thought to be......
