Kudu
Beauty Of Animal | Kudu | The kudu is a sub-species of antelope are found inhabiting shrub mixed forest and savanna plains in eastern and southern Africa. Kudu is very dependent on the close, dense thicket where the kudu can escape to and hide when they feel threatened. There are two species of the African kudu kudu Lesser and greater kudu. These two species are closely related and have to
Ringed Seal
The Life of Animals | Ringed Seal | The ringed seal is the smaller and more common in the Arctic, with a small head, short muzzle like a cat and a plump body. The ringed seal taxonomy is discussed and reviewed in the literature. The ringed seal is very near the Caspian seal (P. caspica) and Baikal seal (P. sibirica), they all have the same relative sizes small, the functions of cranial morphology and affinity for ice actions.The closest phylogenetic relatives ringed seal, gray seal (Halichoerus grypus) and species in the genus Phoca (seals and sealing largha) when ringed seals were attributed above. along with the other northern latitude ice seals (seal, bearded seal, seals and hooded seals), these seals of the subfamily Phocinae
Ringed seals occur throughout the Arctic. You can, in the Baltic Sea, the Bering Sea and Hudson Bay. They prefer to rest on ice floe and continued north on thicker ice. In all the seas of the Arctic in the North Pacific, are found in the southern Bering Sea and range found as far south as the Seas of Okhotsk and Japan. In the assortment ringed seals have an affinity for ice-covered waters and ice to fill seasonal and permanent are great.
Distribution in Alaska Ringed seals in the Beaufort, Chukchi and Bering Sea, south of Bristol Bay in years of extensive ice cover. At the end of April to June ringed seals are distributed throughout their range from the south to the north of the ice edge. The preliminary results of recent studies in the Chukchi Sea in May and June were conducted in 1999 and 2000 indicate that ringed seal density is higher in the ice along the coast and fast package, and lower on sea ice. Ringed seals are found in Arctic waters and often with icebergs and ice, ringed maintains a hole in the ice to breathe so use the ice habitat is not connected, the other joints.Ringed seals are an important food source, especially for the polar bears. Early Paleo Eskimo sites in the Canadian Arctic ringed seals signs harvested from about 4000-3500 BP, probably frozen tears and bears trapped in the ice, with an option for adolescents and young adults.
The bycatch in fishing nets, trawls and trade is another threat to ringed seals. Climate change is the greatest potential threat to ringed seal populations because much depends on their habitat Birthing ice caves are often destroyed before the seal is able to feed itself in a poor physical condition was.

California Condor
The Life of Animals | California Condor | The Condor adult California is a black uniform, with the exception of the large triangular patches or bands of white at the bottom of the wings. Has mottled gray instead of white on the underside of the wing feathers. As an adaptation for hygiene, the condor head and neck have few feathers, which the skin to the sterilizing effects of dehydration and ultraviolet light at high altitudes exposes. The skin of the head and neck can wash strong. Birds have no real syringeal sounds. To determine the most measurements are taken from birds in captivity, so if there are significant differences in measurements between wild condors in captivity is difficult. California condor is the largest wingspan of a bird in North America. The Crane American White Pelican and scream even more jobs than the condor. Condor are so great.
The middle of the foot Californian condor is very elongated, and the hind legs slightly developed. The condors live in rocky scrub, pine forests and oak savannas. There are two shrines dedicated to this bird, the Sisquoc Condor Sanctuary in the desert of San Rafael and the Sespe Condor Sanctuary in Los Padres National Forest. These areas were chosen for their first condor nesting habitat. When in flight, the movements of the condor are very beautiful. The California condor has a long lifespan, up to 60 years. If it survives to adulthood, the condor has few natural threats other than humans.
The display voice grunts and wheezes limited. Condors bathe frequently and can spend hours each day cleaning their feathers. Condors lead urohidrosis or defecate on their legs to their body temperature to decrease. There is a well developed social structure within large groups of condors, with whistling competition in a hierarchical order by body language, behavior competitions, and a variety of grunts and determine decided. This social hierarchy is displayed especially when the birds to eat, eat of the judgment for the young birds.
In order to attract a potential mate, the male condor performs a display. The display is red head man and puffs its feathers of the neck. Spread your wings and slowly approaches the female. If the woman lowers her head to accept the male, the condors are friends for life. The egg weighs about 280 grams (10 ounces) and measuring 90 to 120 mm (3.5 to 4.75 inches) long and about 67 mm (2.6 inches) wide. If the chick or egg is lost or removed, were the parents "double clutch" or an egg to the place lost. The eggs hatch after 53-60 days of incubation by both parents.
Ready to focus their energies on a new nest Ravens are the main predators of eggs condor threats, while eagles and bears offspring condor potential predators. Unusually, this bird takes different roles in the history of the different tribes. The Wiyot tribe of California say that the condor recreated mankind after Above Old Man wiped humanity with a flood. Condor then seized Ground Squirrel after he fled, but Ground Squirrel managed to cut off the head with Condor Condor paused to take a sip of blood. After Yokut tribe, the condor sometimes ate the moon, so the moon cycle, and its wings caused eclipses. The Chumash tribe of Southern California believed that the condor was once a white bird, but it was black when he flew too close to the fire.
Condor bones have been found in graves as Indians have condor feather headdresses. Cave paintings of condors are discovered. Some tribes ritually slain robes to condors from their pens. Shamans then danced while wearing them reaching the higher and lower spiritual worlds. Some scientists, such as Noel Snyder believes that this process has helped ceremonial robes help the condor decline

The Life of Animals | Kinkajou | A Kinkajou adult weighs 1.4 to 4.6 kg (3-10 lb). The adult body of 40-60 cm (16-24 inches), along the length of the body, the tail is long 40-60 cm (16-24 inches). The Kinkajou wool coat consists of an outer layer of gold (or brownish-gray) overlapping a gray coat. It has large eyes and small ears. Kinkajous Range from the east and south of the Sierra Madre in Mexico, through Central America to Bolivia east of the Andes and the rainforest in southeastern Brazil. Although ranked Kinkajou Carnivora and has sharp teeth, omnivorous diet consists mainly of fruits. Kinkajous especially enjoy figs. It has been suggested, without direct evidence that occasionally bird eggs and small vertebrates eat.
The Kinkajou thin five inch extrudable tongue helps the animal and plant get the licking nectar from flowers, so that it can act as pollinators.

Blue Marlin
The Life of Animals | Blue Marlin | Tropical Blue Marlin in the world and the ocean waters, occurring both in the Atlantic and Indo-Pacific. The warm currents such as the Gulf Stream in the western Atlantic and the Agulhas Current western Indian Ocean serve as roads ocean of blue marlin and migration have a strong influence on the seasonal distribution. Individuals have a greater tolerance to higher temperature, and blue marlin found the limits of their range tend to be big fish. Some blue marlin is located in the extreme south of the continent, even though parts of Atlantic-Pacific is questionable, especially since a tagged fish in the western Atlantic was re-captured the island of Mauritius in the Indian Ocean.
In Pacific Blue Marlin are seasonally found as far north as southern Japan and south of the Bay of Plenty in the North Island of New Zealand. The blue marlin in the eastern Pacific migrate northward to southern California and south to northern Peru. The southern limit of its range in the Indian Ocean east seem to Albany and Perth, Western Australia, and the western Indian Ocean blue marlin were taken south of Cape Town. In temperate waters, warm currents interact with these structures is essential background to create the environmental conditions for fishing for blue marlin and hot water to another. Temperature breaks created bodies of hot and cold water are pushed against each other as a less tangible which attracts bait and fishing, including blue marlin.
Catch the greatest in the sport fishing record is £ 1805 Pacific Blue Marlin caught by a group of fishermen in Oahu, Hawaii on the charter boat commanded by Captain Cornelius Choy Coreene C (this fish often referred to as "monster Choy '). Commercial fishermen began much larger samples. Largest blue marlin early market of Tsukiji in Tokyo presumably weighed 1.106 kg mass. At least 1,000 pounds (450 kg) of fish, a "great", has historically been considered by fishermen to fish for blue and black marlin truly exceptional. For most Billfish fishing, the fish represents 1,000 pounds of fish life.
Blue marlin feeding eclectic use of a wide range of prey species and sizes. The scientific analysis of stomach contents of blue marlin have organisms as small as miniature filefish. Of greater interest for fishermen is the upper range of prey size blue marlin. The 72-inch white marlin was recorded as being found in the stomach of a blue marlin caught 448 pounds in Walker Cay in the Bahamas, and, more recently, in 2005, White Marlin Open a white marlin on 70 pound class are in the stomach of one of the blue stripes. Spearfish marlin 30 to 40 pounds have been reported as part of Kona Blue Marlin fishing source. Tuna of 100 pounds or more were also found in the stomachs of large blue marlin. Scientists distinguish two species of blue marlin, Atlantic Blue Marlin (Makaira nigricans) and Pacific Blue Marlin (Makaira Mazara).
Exceptionally beautiful blue marlin is the largest of the Atlantic marlins and one of the world's largest fish. Women are much larger than males, can reach 14 feet (4.3 m) long and weigh more than 1,985 pounds (900 kg). Native to tropical and temperate waters of the Atlantic, Pacific and Indian Oceans, Blue Marlin are among the best known of all fish. Cobalt blue is below the top and silvery white, with a distinctive dorsal fin and a long and deadly, spear-shaped upper jaw. They are called blue-water fish spend most of their lives at sea.

Nudibranch
The Life of Animals | Nudibranch | The body forms of nudibranchs vary widely, but because they are opisthobranch, unlike most other shells are bilaterally symmetrical, both externally and internally, because they suffered secondary detorsion. The adult form is without a shell or capsule (the capsule shell is a bone plate or horny that can cover the opening of the shell when the body is removed). In contrast to the rear of the keyboard aeolids Cladobranchia in bright colors are sets of protruding organs called cerata. Nudibranchs have cephalic (head) tentacles, which are sensitive to taste, touch and smell. Club-shaped rhinophores detect the odors.
Nudibranchs typically deposit their eggs in a gelatinous spiral. All known nudibranchs are carnivorous. Other groups of tunicates feed (eg Tambja, Nembrotha, Polycera, Thecacera), other nudibranchs (Roboastra, descending-feeding tunicate species), barnacles (eg Onchidoris) and anemones (eg Cladobranchia Aeolidiidae and others). The surface dwelling nudibranch Glaucus atlanticus is a specialist predator siphonophores like the Portuguese Man O War "This predatory mollusk sucks air into the stomach to hold the liquid and leg muscle that clings to the film surface.
During evolution, sea slugs have lost their shell because they have developed other defense mechanisms. Some species have developed external anatomy with textures and colors that mimicked the plants around to avoid predators (see camouflage). Nudibranchs that feed on hydroids can store the nematocysts hydroids "(stinging cells) in the dorsal body wall, the cerata. Estes, called nematocysts kleptocnidae stolen, stroll through the digestive tract without harming the nudibranch. Nudibranchs can protect hydroids and their nematocysts., it is unclear how, but special cells with large vacuoles probably play an important role.
Some nudibranchs sponge-food concentrate their toxins replacement sponge in the body, making it toxic to predators. The evidence suggests that no toxins used by nudibranchs Dorid actually come from fungi diet lies in the similarities between the primary and secondary metabolites of prey and nudibranchs, respectively. Additionally nudibranchs contain a mixture of chemicals when the mushrooms in the presence of various power supplies and protection chemistry changes with a simultaneous change in diet. However, that is not the only way to develop nudibranchs chemical defense.
Evidence of different production methods will chemical composition is uniform across the drastically different environments and geographical locations are around species production compared with the vast array of new chemical composition of diet and environment dependent medium complexing species. Another method is to protect an acid release from skin. When the sample is physically irritated or touched by other creature, shall be released automatically mucus.

African Wild Dog
The Life of Animals | African Wild Dog | It 'the only canid species lack dewclaws on the front legs. This is the largest canid Africa, just behind the gray wolf, is the world's second largest wild canid exists. Animals in southern Africa are generally larger than the east or west. Has a dental formula consists of 42 teeth. Premolars are relatively large compared with those of other canids, so that a large quantity of bone, much like hyenas consume. The African wild dog has a bite force measured ratio (BFQ, bite force on the mass of the animal) at 142, the highest existing mammalian order Carnivora, although exceeded by the Tasmanian devil, a marsupial carnivore. Can kill at the age of 8-11 months small prey, but depend on the pack kills most of their food. Wild dogs reach sexual maturity at the age of 12-18 months.
The females of the pack of birth until 14-30 months old disperse and join other packs that lack sexually mature females. Among the wild dogs compete women access to males that. The practice may leave adults behind the guard puppies hunting efficiency in smaller packages to reduce The packages are divided into male and female hierarchies. Previously it was thought that if a division of alpha-chip package, but this was rejected (albeit on a small scale) by Mutual of Omaha Wild Kingdom, in which 6 dogs that had been raised in captivity (reached only 5 the island, a died of anesthesia) lost their two alpha, which purports to be fixed crocodiles, but the 3-pack and a new alpha male and the female were. In the group of women, the oldest will have alpha status over the others, so keep a mother her alpha status over her daughters and sisters. Among men, the father's brother and many others are dominant dominant without a father or a brother, the other to be the new dominant breeders.
If two to this lonely separate sexes meet, they may form a pack, if not correlated. Independent wild dogs are sometimes in groups, but this is usually temporary. In contrast, the wild dogs occasionally hostile independent experiments buy packages. In the Serengeti, the average dog density (prior to local extinction of the species) a dog for every 208 square kilometers (80 square miles), while in the Selous Game Reserve, the average density was 1 dog every 25 square kilometers (9, 7 square MI). In the Serengeti, the average range at 1,500 square kilometers (580 square miles) is estimated, although individual ranges overlap extensively. It once approximately 500,000 African Wild Dogs in 39 countries, and packs of 100 or more were were not uncommon. Smaller populations, but surely, apparently several hundred people in Zimbabwe (Hwange National Park), South Africa (Kruger National Park), and the complex Ruaha / Rungwa / Kisigo Tanzania. Isolated populations persist in Zambia, Kenya and Mozambique.
The African wild dog is to fight by human overpopulation, habitat loss and killing endangered predators. Used very large areas (they can only exist in large protected areas), and is strongly influenced by competition with larger carnivores that rely on the same prey base, particularly the lion and hyena. While adult wild dogs run faster pace than larger predators, lions often kill as many wild dogs and puppies to chew on the site, but can not eat. One by one the hyena is much more powerful than the wild dog, but a large group of wild dogs hunt successfully, a small number of hyenas because of their teamwork. Most of the national parks in Africa are too small for a pack of wild dogs, and tend to be expansion packs for protected areas, ranch or farm land. Breeders and farmers to protect their domestic animals by killing the wild dogs. Like other carnivores, the African wild dog is sometimes affected by outbreaks of viral diseases such as rabies, distemper and parvovirus. Although these diseases are no longer pathogenic or virulent for wild dogs, the small size of most wild dog populations to the risk of local extinction due to illness or other problems.
