Black Panther

Monday, 29 October 2012

Black Panther:  A black panther is typically a melanistic color variant of any of several species of larger cat. In Latin America, wild 'black panthers' may be black jaguars (Panthera onca); in Asia and Africa, black leopards (Panthera pardus); in Asia, possibly the very rare black tigers (Panthera tigris); and in North America they may be black jaguars or possibly black cougars (Puma concolor – although this has not been proven to have a black variant), or smaller cats.Melanism in the jaguar (Panthera onca) is conferred by a dominant allele, and in the leopard (Panthera pardus) by a recessive allele. 

Close examination of the color of these black cats will show that the typical markings are still present, but are hidden by the excess black pigment melanin, giving an effect similar to that of printed silk. This is called "ghost striping". Melanistic and non-melanistic animals can be littermates. It is thought that melanism may confer a selective advantage under certain conditions since it is more common in regions of dense forest, where light levels are lower. Recent, preliminary studies also suggest that melanism might be linked to beneficial mutations in the immune system.

Parrot

Parrot:  Parrots, also known as psittacines are birds of the roughly 372 species in 86 genera that make up the order Psittaciformes, found in most tropical and subtropical regions. The order is subdivided into three superfamilies: the Psittacoidea ('true' parrots), the Cacatuoidea (cockatoos) and the Strigopoidea (New Zealand parrots). Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere as well. 

The greatest diversity of parrots is found in South America and Australasia.Characteristic features of parrots include a strong, curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured. The plumage of cockatoos ranges from mostly white to mostly black, with a mobile crest of feathers on the tops of their heads. Most parrots exhibit little or no sexual dimorphism. They form the most variably sized bird order in terms of length.

Patas Monkey

Patas Monkey:  The patas monkey, also known as the Wadi monkey or Hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa. It is the only species classified in the genus Erythrocebus. Recent phylogenetic evidence indicates that it is the closest relative of the vervet monkey (Chlorocebus aethiops), suggesting nomenclatural revision.The patas monkey grows to 85 cm (33 in) in length, excluding the tail, which measures 75 cm (30 in). Adult males are considerably larger than adult females. Reaching speeds of 55 km/h (34 mph), it is the fastest runner among the primates.

The patas monkey lives in multi-female groups of up to 60 individuals (although much larger aggregations have been reported). The group contains just one adult male for most of the year. During the breeding season, there are multi-male influxes into the group. Once juvenile males reach sexual maturity (around the age of 4 years old) they leave the group, usually joining all-male groups. The adult females in the group initiate movement of the group with the male following their lead.

Peafowl

Monday, 22 October 2012

Peafowl:  Peafowl are three Asiatic species of flying bird in the genus Pavo of the pheasant family, Phasianidae, best known for the male's extravagant eye-spotted tail, which it displays as part of courtship. The male is called a peacock, the female a peahen, and the offspring peachicks. The adult female peafowl is grey and/or brown. Peachicks can be between yellow and a tawny colour with darker brown patches. The term also embraces the Congo Peafowl, which is placed in a separate genus Afropavo.The male (peacock) Indian Peafowl has iridescent blue-green or green colored plumage. 

The peacock tail ("train") is not the tail quill feathers but the highly elongated upper tail covert feathers. The "eyes" are best seen when the peacock fans its tail. Like a cupped hand behind the ear, the erect tail-fan of the male helps direct sound to the ears. Both species have a crest atop the head. The female (peahen) Indian Peafowl has a mixture of dull green, brown, and grey in her plumage. She lacks the long upper tail coverts of the male but has a crest. The female can also display her plumage to ward off female competition or signal danger to her young.

Pelican

Pelican:  Pelicans are a genus of large water birds comprising the family Pelecanidae. They are characterised by a long beak and large throat pouch used in catching prey and draining water from the scooped up contents before swallowing. They have predominantly pale plumage, the exceptions being the Brown and Peruvian Pelicans. The bills, pouches and bare facial skin of all species become brightly coloured before the breeding season. The eight living pelican species have a patchy global distribution, ranging latitudinally from the tropics to the temperate zone, though they are absent from interior South America as well as from polar regions and the open ocean.

 Fossil evidence of pelicans dates back at least 30 million years, to the remains of a beak very similar to that of modern species recovered from Oligocene strata in France.Long thought to be related to frigatebirds, cormorants, tropicbirds, gannets and boobies, pelicans are now known instead to be most closely related to the Shoebill and Hammerkop, and are placed in the order Pelecaniformes. Ibises, spoonbills and herons are more distant relatives, and have been classified in the same order.

Penguin

Penguin:  Penguins (order Sphenisciformes, family Spheniscidae) are a group of aquatic, flightless birds living almost exclusively in the southern hemisphere, especially in Antarctica. Highly adapted for life in the water, penguins have countershaded dark and white plumage, and their wings have evolved into flippers. Most penguins feed on krill, fish, squid, and other forms of sealife caught while swimming underwater. They spend about half of their lives on land and half in the oceans.

Although all penguin species are native to the southern hemisphere, they are not found only in cold climates, such as Antarctica. In fact, only a few species of penguin live so far south. Several species are found in the temperate zone, and one species, the GalƔpagos Penguin, lives near the equator. The largest living species is the Emperor Penguin (Aptenodytes forsteri): on average adults are about 1.1 m (3 ft 7 in) tall and weigh 35 kg (75 lb) or more.

Pheasant

Friday, 19 October 2012

Pheasant:  Pheasants refer to some members of the Phasianinae (Horsfield, 1821) subfamily of Phasianidae in the order Galliformes. Pheasants are characterised by strong sexual dimorphism, males being highly ornate with bright colours and adornments such as wattles and long tails. Males are usually larger than females and have longer tails. Males play no part in rearing the young. Pheasants typically eat seeds and some insects. The best-known is the Common Pheasant, which is widespread throughout the world in introduced feral populations and in farm operations. Various other pheasant species are popular in aviaries, such as the Golden Pheasant (Chrysolophus pictus).

Pied Tamarin

Pied Tamarin:  The pied tamarin (Saguinus bicolor) is an endangered primate species found in a restricted area in the Brazilian Amazon Rainforest. This New World monkey is found within and just north of the city limits of Manaus, the capital of the Amazonas state of Brazil. The main distribution is in the rio Cuieiras and rio Preto da Eva interfluvium. Pied tamarins are also found in the adjacent rio Preto da Eva and rio Urubu interfluvium, but are comparatively rare. 

There appears to be interspecific competition between the pied tamarin and the red-handed tamarin with the red-handed tamarin gradually displacing the pied tamarin from areas of its historical distribution. There are therefore multiple threats to the long term survival of the pied tamarin that stem from habitat destruction and from interspecific competition.The pied tamarin's body measures 20.8–28.3 cm.; including the tail it measures 33.5–42.0 cm. Males weigh 428 grams (n = 4).[6] Its life expectancy is approximately 10 years in the wild.

Pig

Pig:  A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig, its ancestor the wild boar, and several other wild relatives. Pigs are omnivores and are highly social and intelligent animals. A typical pig has a large head with a long snout which is strengthened by a special prenasal bone and by a disk of cartilage at the tip. The snout is used to dig into the soil to find food and is a very acute sense organ. 

There are four hoofed toes on each trotter (foot), with the two larger central toes bearing most of the weight, but the outer two also being used in soft ground. The dental formula of adult pigs is Upper: 3.1.4.3, lower: 3.1.4.3, giving a total of 44 teeth. The rear teeth are adapted for crushing. In the male the canine teeth form tusks, which grow continuously and are sharpened by constantly being ground against each other.

Pika

Monday, 15 October 2012

Pika:  The pika is a small mammal, with short limbs, rounded ears, and no external tail. The name pika is used for any member of the Ochotonidae, a family within the order of lagomorphs, which also includes the Leporidae (rabbits and hares). One genus, Ochotona, is recognised within the family, and it includes 30 species. It is also known as the "whistling hare" due to its high-pitched alarm call when diving into its burrow. The name "pika" appears to be derived from the Tungus piika.

Pikas are native to cold climates, mostly in Asia, North America and parts of eastern Europe. Most species live on rocky mountain sides, where there are numerous crevices to shelter in, although some also construct crude burrows. A few burrowing species are instead native to open steppe land. In the mountains of Eurasia, pikas often share their burrows with snowfinches, which build their nests there.

Piranha

Piranha:  A piranha or piraƱa  is a member of family Characidae in order Characiformes, an omnivorous freshwater fish that inhabits South American rivers. In Venezuela, they are called caribes. They are known for their sharp teeth and a voracious appetite for meat. Piranhas belong to the subfamily Serrasalminae, which also includes closely related omnivorous fish such as pacus. Traditionally, only the four genera Pristobrycon, Pygocentrus, Pygopristis and Serrasalmus are considered to be true piranhas, due to their specialized teeth. 

However, a recent analysis showed that, if the piranha group is to be monophyletic, it should be restricted to Serrasalmus, Pygocentrus and part of Pristobrycon, or expanded to include these taxa plus Pygopristis, Catoprion, and Pristobrycon striolatus. Pygopristis was found to be more closely related to Catoprion than the other three piranha genera. The total number of piranha species is unknown and contested, and new species continue to be described. Estimates range from fewer than 30 to more than 60.

Platypus

Platypus:  The platypus (Ornithorhynchus anatinus) is a semi-aquatic mammal endemic to eastern Australia, including Tasmania. Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth. It is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species have been found in the fossil record. The unusual appearance of this egg-laying, venomous, duck-billed, beaver-tailed, otter-footed mammal baffled European naturalists when they first encountered it, with some considering it an elaborate fraud. 

It is one of the few venomous mammals, the male platypus having a spur on the hind foot that delivers a venom capable of causing severe pain to humans. The unique features of the platypus make it an important subject in the study of evolutionary biology and a recognisable and iconic symbol of Australia; it has appeared as a mascot at national events and is featured on the reverse of the Australian 20 cent coin. The platypus is the animal emblem of the state of New South Wales.

Polar Bear

Sunday, 14 October 2012

Polar Bear:  The polar bear (Ursus maritimus) is a bear native largely within the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest land carnivore and also the largest bear, together with the omnivorous Kodiak Bear, which is approximately the same size. A boar (adult male) weighs around 350–680 kg (770–1,500 lb), while a sow (adult female) is about half that size.

Although it is closely related to the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet.Although most polar bears are born on land, they spend most of their time at sea. Their scientific name means "maritime bear", and derives from this fact. Polar bears can hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present.
