Pipefish

 

The Life of Animals | Pipefish | Needles to instantly look healthy seahorses with tiny mouths. The body and tail are long, thin, and the serpent. The dorsal fin is always present, and is the primary (in some species, the only) body movement. Gill openings very small, and placed next to the upper rear corner of the gill covers. Some types of needles have tails that intervention, such as in seahorses. The Pipefishes one form or another of the tail fin (as opposed seahorses), which can be used for the moved. See the description of the anatomy of the fish fin.


There are types of needles with more developed caudal fin, as a group known as the needles the marine inhabitants and some freshwater species. Pipefishes in abundance on the shores of tropical and temperate zones. There are about 200 species of pipefish. Pipefishes and family of seahorses, while most parental males. Courtship usually carefully choreographed display of men and women.


Other species are partially or even completely designed bag to carry eggs. Many exhibitions polyandry breeding with a female fit with two or more men. This leads to an increased incidence of internal brooding pipefish species, what types of external brooding. Some young people have a short larval stage and live as plankton for a short time. Other fully developed, miniature versions of their parents, believing that the same behavior as their parents immediately.  needles, which are very strong swimmers.

Sea Horse

 

The Life of Animals | Sea Horse | Sea Horse size from 0.6 to 14, look for their horses named. Each species has a distinct number of rings. Seahorses swim upright, another characteristic that is not shared by their close pipe fish relatives, which swim horizontally. Unusual among fish, seahorses have a flexible, well-defined neck. Seahorses have no tail. The fossils of seahorses is very scarce. The earliest known fossils of seahorses are two pipefish-like species, H. and H. Sarmaticus slovenicus of coprolitic horizon Tunjice Hills, a middle Miocene deposits in Slovenia is about 13 million years ago. Molecular dating is that pipefish and seahorses separated in the late Oligocene.


The male seahorse nest provided with a pocket on his stomach, or for a specific, silk. When mating, the female seahorse deposits up to 1,500 eggs in the pouch of the male. The male carries the eggs for 9 to 45 days out to go to the seahorses fully developed, but very small. Once the seahorses into the water, dismissed the male role and he has done no further care. is a common misconception about seahorses that they mate for life. Many species of seahorses form pair bonds that last through at least the breeding season. Some species show a higher degree of loyalty than other partners. However, many species easily switch mates when the opportunity arises.


Seahorses feed on small crustaceans in the water swimming or crawling on the floor. With great stealth and patience, ambush prey that seahorses floating within striking distance range. Mysid shrimp and other small crustaceans are favorites, but some eat seahorses observed other species of invertebrates and even fish larvae.


Many species of seahorses are inadequate data, and there is not enough information about their risk of extinction, to judge. Since the seahorse populations is unknown, there is a risk of losing more sea horses, because of the lack of information about how many die each year, how many are born, the number of souvenirs etc. deteriorating coral reefs and seagrass beds, reducing viable habitat for seahorses. While many hobbyists keep seahorses as pets, seahorses tend by nature a poor home in aquariums.


Although more expensive captive bred seahorses, they take no toll on wild populations. Seahorses are slow eaters will be as fast, aggressive investors, they leave without food. Seahorses can co-exist with many species of shrimp and other bottom-feeding creatures. Goby, a good tank-mates. Keepers will usually avoid eels, surgeon fish, trigger fish, squid, octopus, sea anemones and advice. To animals as "freshwater seahorses" sold, are usually the closely related pipefish, of which some species live in the lower reaches of rivers. The supposed true "freshwater seahorse" called H. Aimei not true species, but a name was sometimes used by Barbour and Hedgehog seahorse. The latter is a species that are found in brackish water, but can not truly a freshwater fish.

Seahorse population is believed to have been in recent years threatened by overfishing and habitat destruction. The seahorse is used in traditional Chinese herbalism, and shall not be less than 20 million seahorses may be caught and sold for this purpose. Medicinal seahorses are not easily bred in captivity, because they are susceptible to disease and you take on different medicinal properties of seahorse tank must have. Seahorses are also used as medicines by the Indonesians, the Filipinos used Central and many other ethnic groups. Import and export of seahorses is under CITES since the 15th May 2004 regulated.


Declining availability of the large, pale and smooth seahorses has been the shift towards prepackaged medicines it possible for TCM merchants to sell previously unused juvenile, spiny and dark-colored animals, make resolves. Today, nearly a third of the seahorses sold in China are prepackaged, in addition to the pressure of the species. Pygmy seahorses are less than 15 millimeters (0.59 inches) long and 17 millimeters (0.67 inches) wide members of the genus. Molecular analysis (ribosomal RNA) from 32 species revealed that H. hippocampus bargibanti belongs in a clade separate from other members of the genus, so that the species differs from other species in the "old" past. Most are well camouflaged and pygmy seahorses live in close collaboration with other organisms, including colonial hydrozoans (Lytocarpus and Antennellopsis), calcareous algae (Halimeda), gorgonians (Muricella, Annella, Acanthogorgia).

Curly Horse

 

The Life of Animals | Curly Horse | The Curlies are known for their calm personality, smart and friendly. Most people found that Curlies enjoy the company of people. The Curlies are generally non-volatile. The single gene that gives Curlies their curly hair (which is most evident in the winter) can be expressed as a (horse exhibits curly hair inside the ears, balls, and a tangled mane and tail) at the minimum, maximum horse shows clusters throughout the body, dreadlocked mane, and has curly eyelashes and guard), and "Extreme" (very tight, extreme curls, but when they poured out for the summer can shed entirely bald) or variations. Curlies have split manes and are not twisted or cut when shown.  Care for curly hair is simple.


All proceeds go to research efforts Icho Curly. Curlies are acclaimed as the only hypoallergenic bloodstock, most people who are allergic to horses can go Curly Horses without suffering an allergic reaction. Survey shows lack of a protein in the hair of Curlies which may be the cause of allergic reactions to horses in allergy suffers, but the study was never published officially. Members of the Curly Community are working on funding for more research on thisthe Curly has a characteristic step length and bold move. Most Curlies stand between 14 and 16 hands, but can range from miniature horses to Draft horses (Only allowed on two records). The origin of the Curly horse is much debated in the Curly community, but research is mostly still in full swing.


ABCR members prefer "Bashkir Curly," as members of the CSI and Icho tend to "North American Curly." It is said that the Curly horses were documented in Asian artwork as early as 161 AD. Charles Darwin documented key horses in South America in the early 19th century and early Sioux Indians regarded horses keys as sacred mounts for chiefs and healers. Native American art shows Curlies Warriors at the Battle of Little Bighorn. Note that foals horses raised through the curly hair.


The Curly Horse was first documented in Eureka, Nevada in the early 20th century by John Farmer Damele and their children. While Mustangs were a normal phenomenon, Curly Coated horses were unusual. After a harsh winter in 1951/52, the Dameles began in earnest the creation of these horses. Curlies are characteristically quiet, sober horses an excellent first horse for novice riders followed. Curlies led horse-allergic state for beginner riders increasingly advanced stages of equestrian sports. They are also used for combined driving, western riding, horse farm, horse track and comrades from other horses. Some Curlies were crossed with gaited horses.  Curlies are not used for racing or trotting shows high

Poison Dart Frog

 

The Life of Animals | Poison Dart Frog | Most dart frog species of venomous are small, sometimes less than 1.5 cm (0.59 inches) in length for adults, although some grow to 6 cm (2.4 inches) in length. Weigh approximately 2 grams, depending on the size of the frog. Most poison dart frogs are color images, aposematic display to warn potential predators. The frogs such as Dendrobates species have high levels of alkaloids, while Colostethus species are cryptically colored and non-toxic. Poison frogs are an example of an aposematic organism. Their bright coloration advertises appetite potential predators. Adult frogs lay their eggs in moist places, such as leaves, plants, among exposed roots, and elsewhere. The poison arrow frog is an amphibian.


The tadpoles remain until metamorphosis, fed unfertilized eggs at regular intervals established by the motherPoison frogs are endemic to the humid tropics of Central America and Latin America (South America). These frogs are usually found in tropical forests in Bolivia, Costa Rica, Brazil, Colombia, Ecuador, Venezuela, Suriname, Guyana, Peru, Panama, Guyana, Nicaragua and Hawaii (introduced). Natural habitats include subtropical or tropical moist forests of the lowlands, tall bushes subtropical or tropical moist, subtropical or tropical Montanes and rivers, freshwater marshes, intermittent freshwater marshes, lakes and swamps.


Many species of poison dart frogs are dedicated parents. Tadpoles feed on invertebrates in tree nursery, and his mother also supplement their diet by depositing their eggs in water. Other poisonous frogs lay their eggs on the forest floor, hidden under layers of leaves. Poison frogs fertilize the eggs externally, ie, the female lays a clutch of eggs the male fertilizes them later in the same way that fish (external fertilization). Poison frogs can often be seen hugging, like most frogs copulating. The operational sex ratio in the poison dart frog family is largely avoided women.


Females select mates based on color (mostly dorsal) position calling perch, and the territory Some species of poison dart frogs include a number of color forms species that have emerged recently as 6,000 years ago. A previous study on the evolution of skin coloration and toxicity of the family Dendrobatidae indicated that the development of skin toxicity was significantly correlated with the evolution of bright coloration. In support of this research, another study went on to explain that the color was visible also significantly correlated with dietary specialization of a poison frog, their body mass and chemical defense. This study has found that polymorphic poison dart frogs, which are less visible are more toxic than the brightest and most visible species, sequestration of alkaloids in frogs has been less visible considered strong convulsion proposed as an explanation for this result. Many species of poison dart frogs have recently experienced the loss of habitat (due to logging and agriculture) and chitridi diseases.

Bald Eagle

  
The Life of Animals | Bald Eagle | The plumage of an adult Bald Eagle is evenly brown with a white head and tail. The tail is moderately long, slightly wedge-shaped. Males and females are identical in plumage color, but the sexual dimorphism is evident in species in which women are 25 percent larger than males. The mouthpiece is large and hook-shaped, with cerebral yellow. Immature eagles are distinct from the Golden Eagle in that the former has a more excellent head with a large beak, sharp straight wings held flat (not slightly raised) and a hit hardest, and the wing feathers that do not completely cover the legs. The Bald Eagle is sometimes considered the largest bird of prey is the case in North America (except California Condor possibly unrelated), although the species overlap in size with the races of the American Golden Eagle.

 

Females
are about 25 percent larger than males, with an average of 5.8 kg (13 lb) and against the male of average weight of 4.1 kg (9.0 lb). The eagles are larger than Alaska, where large females can weigh up to 7.5 kg (17 lb) and length 2.44 m (8.0 ft) across the wings. The call consists of weak chirping whistles, louder and more shrill from young birds than adults. The Bald Eagle prefers habitats near seacoasts, rivers, lakes, oceans and other large bodies of open water with abundant fish. The Bald Eagle requires old-growth stands and mature pine and hardwood trees for perching, roosting and nesting.


The Bald Eagle is extremely sensitive to human activity, and is most commonly found in areas free of human disturbance. It chooses sites more than 1.2 kilometers (0.75 miles) of the low density human disturbance and more than 1.8 kilometers (1.1 miles) of medium to high density human disturbance. Sometimes eagles will in large estuaries or woodlands isolated in large cities like hardtack Island in the Willamette River in Portland, Oregon or John Heinz National Wildlife Refuge at Tinicum in Philadelphia, Pennsylvania. Despite this sensitivity, a family of bald eagles moved to Harlem in New York in 2010 The Bald Eagle Natural Area covers most of North America, including the largest, Canada's all continental United States and northern Mexico. It is the only sea eagle endemic in North America.


Bald Eagles also in certain places in the winter. From November to February, two thousand birds winter in Squamish, British Columbia, halfway between Vancouver and Whistler. The birds primarily gather along the Squamish and Cheakamus Rivers, attracted by spawning salmon in the area. The bald eagle is a powerful insect, and increases the thermal convection currents. It reaches speeds of 56-70 mph (35-43 mph) when gliding and flapping, and about 48 kilometers per hour (30 mph) that fish. It is partly migratory species, depending on the location. The Bald Eagle selects migration routes which use thermal updrafts, and food sources. The bald eagle diet is opportunistic and varied, but in some areas they feed mainly on fish. Locally, eagles depend largely on carrion, especially in winter.


Mammalian prey includes rabbits, hares, raccoons, muskrats, beavers, deer and fawn. Birds occasionally be attacked in flight with prey, such as Canada geese captured and slain, while in the air. Long live prey are slightly smaller than the eagle, but predation was recorded for the animals to the size of adult swans, raccoons and young adult ungulates, which are heavier than the bald eagles. In the Chesapeake Bay, bald eagles are important enemies of raccoons. To hunt fish, easily their most important live prey, the eagle swoops down over the water and grab the fish out of water with its claws. Eagles have structures called spicules on their toes that allow them to seize the fish.  Eagles have powerful talons and are included to fly with a fawn deer Mule £ 15.


Eagles can fly fish at least equal to its weight, but if the fish is too heavy to lift, the eagle can be dragged into the water. You can swim to safety, but some eagles drown or succumb to hypothermia. By competing for food, eagles usually dominate other fish-eaters and scavengers, aggressively displacing mammals such as coyotes and foxes and birds such as crows, gulls, vultures and other raptors. Bald Eagles can be moved by you or golden eagles.  Occasionally, eagles steal fish and other prey away from smaller raptors such as ospreys, a practice known as kleptoparasitism. Healthy adults are not plagued eagles in nature and therefore are considered predators. In one case, an adult eagle investigating a nest prey Peregrine suffered a concussion of a pilgrim father swooping and eventually died a few days afterwards. Bald Eagles are sexually mature at four or five years old.


It is believed that eagles pairs for life. Eagle undergoes extensive courtship calls and flight displays. Nest is the largest of all birds in North America, which is used repeatedly over many years and new material added each year, eventually as large as four meters (13 feet) deep, 2 5 meters (8.2 meters) in diameter and weigh tons (1.1 short tons) of a nest in Florida was 6.1 meters (20 feet) deep 2.9 meters (9.5 feet) in diameter, and weighs 3 tons (2.7 T). This nest is on record as the largest nest tree has ever known. The nest is made of branches, usually in large trees near water. By producing, where there are no trees, the Bald Eagle will nest on the ground. Both male and female in turn incubating the eggs. Like the size, the average length of an eagle population appears to be influenced by the location, the bald eagle is the national bird of the United States. On 20 June 1782, the Continental Congress adopted the design is still present for the Great Seal of the United States, including an American eagle holding 13 arrows and a branch of olive leaves 13 with its claws. Contrary to popular legend, there is no evidence that Benjamin Franklin has always Wild Turkey, instead of the bald eagle as a symbol of the United States supported.

Pallas Fish Eagle

  
The Life of Animals | Pallas Fish Eagle | It has a light brown tint with a white face. The wings are dark brown back and brown, darker below. The tail is black with a broad white fat. Juveniles are darker overall, with no band on the tail. Women at 2.1-3.7 kg (4.6 to 8.2 lbs), are slightly larger than the males, from 2 to 3.3 kg (4.4 to 7.3 lbs). Since all species is slightly heavier than the eagle, is one of the greatest performance ever measured weightlifting for a flying bird.


This species is most difficult to place the eagle. The cytochrome b mitochondrial DNA sequence data is not able to suggest a reliable phylogenetic space for the bottom of the sea-eagles. However, some data are derived from molecular data, and especially the morphology and biogeography: This species retains the ancestral eye dark, bill and claws of the first sea eagles, shared with the ancient tropical origin. It


Distribution indicates that this species has evolved quite independently of other lines of sea eagle, but molecular data suggest that caution is perhaps closest to the Holarctic species. Apparently, this species reached the current, mainly landlocked particular distribution among sea eagles as a result of the collision of the Indian plate with Eurasia.


Conservation of Pallas's eagle is vulnerable, with a population of about 2,500 to 10,000 remain. In India, the eagle as threatened by the spread of water hyacinth (Eichhornia spp.), Who spread through the lakes and find prey difficult.
