Great Hornbill

 
  
The Life of Animals | Great Hornbill | Great Hornbill large bird, 38-47 in 95-120 cm) in length, with 152 cm (60 inches) wingspan and weight of 2.15-4 kg (4.7-8.8 kg). It's heavy, but no longer hornbill, Asian. The most characteristic feature is the hornbill yellow and black helmet on top of its massive bill. Male hornbills are known to enter into an air helmet butting birds attack each other in flight. Females are smaller than males and have blue-white, and red eyes, although the orbital skin pink. Like other hornbills, there is the famous "eyelashes." In the back of the helmet red for women, and in the lower front and back of the helmet black men. The wing beats are heavy and the sound of birds in flight can be heard from afar. This species was previously divided into subspecies cavatus Western Ghats, to appoint a sub-Himalayan forests are sometimes referred to as a subspecies of homrai. Like other members of the hornbill family, they are very pneumatized bones, the hollow cavity of air that extends to the ends of the wing bones. This anatomical feature is observed Richard Owen, who dissected a sample Zoological Society of London, who died in 1833.


Species distribution is fragmented throughout the range in South and Southeast Asia. In Thailand, the habitat of the males were about 3.7 km during the breeding season, and about 14.7 km ² during the breeding season there. Great hornbills, as typically seen in small parties to larger groups, sometimes adding fruit trees. Assembly from 150 to 200 birds were recorded in south-eastern Bhutan In nature, the Great Hornbill diet consists mainly of fruits. Altissima Vitex is observed as another important species. It was noted that the lion-tailed macaques feed along with these hornbills. They feed on the branches, moving jumps, in search of insects, nestlings, small lizards, break the crust and study them. Proteins rarely, Travancore flying squirrel Petinomys fuscocapillus observed in the diet of species, while Scops Owl Otus bakkamoena collar, Jungle Owlet Glaucidium radiatum and the Gray facade of green Pigeon Treron pompadora observed as birds of prey in the Western Ghats


Very few hornbills are in captivity, and to create good. Women in the nest is very easy to capture and captured wild birds are female biased. Rhinos in captivity, they eat fruit and meat, and a healthy diet consists mainly of fruit and some protein source. Some of them have been domesticated in captivity but hornbill behavior in captivity is described as tense. Tribal threaten Great Indian rhinos, with their desire to its various parts. While dancing with hornbill feathers, do not eat vegetables, but is believed to produce the same foot ulcers conservation programs tried to provide tribes with feathers from captive hornbills and ceramic helmets to replace the natural ones.

Brown Pelican

 
 
The Life of Animals | Brown Pelican | The Brown Pelican occurs on both coasts of the Americas. On the Atlantic coast and Gulf coast, which spread from Nova Scotia to Venezuela, and the mouth of the Amazon River. In the Pacific Ocean are found from British Columbia to South Central Chile, including the Galapagos Islands. Some immature birds may depart interior freshwater lakes. After nesting, North American birds move in flocks further north along the coast, returning to warmer waters for winter. 
 

This bird is the American White Pelican by its brown body and its habit of diving for fish in the air like a fishing cooperative to distinguish from the surface in contrast. Groups of Brown Pelicans often travel in single file, flying low over the water surface.


Pesticides also threatened the pelican population in Florida during this period. Along with the American White Pelican, Brown Pelican is protected by the Law of migratory birds contract in 1918. The International Union for Conservation of Nature Red List listed the brown pelican as Least Concern in 1988, the U.S. government to prohibit the use of DDT imposed in 1972. Since then, the Brown Pelican population increased.

Flatfish

 
  
The Life of Animals | Flatfish | Their most striking feature of flatfish asymmetry, both in the eyes of older adult falls on the same side of the fish. In some families, the eyes are always on the right side of the body (flatfish dextral or right eye), while others are always right (or left-handed flatfish left-eyed). Fish on the surface of the sea floor, pigmented, often serves to camouflage the fish, but sometimes bright color patterns. Side of the body without eyes,


overlooking the sea bed, usually colorless or very light. Only eat small fish and spiny turbot, and a well-developed teeth. Fish dishes range in size from oligolepis Tarphops, measuring about 4.5 cm (1.8 inches) long and weighing 2 grams (0.071 ounces), Atlantic halibut, 2.5 meters (8.2 ft) and 316 kilograms (700 pounds). Flatfish eggs that hatch into larvae, as well as a typical, symmetrical, fish.


Migration through the eyes of one of the most senior and the other side of the body, leaving one side of the blind fish. Larva Swim bladder and spines, and goes down and loses his blind side of the main surface. In 2008, 50 million year old fossil, Amphistium, was identified as an early relative of a transitional flatfish fossil and modern fish dish, the head is asymmetric in both eyes on one side of the head.

Electric eel

 
  
The Life of Animals | Electric eel | Electric eel has three abdominal pairs of organs that produce electricity: the main body, the body hunter, and the authority of Sah. The agencies make up four fifths of his body, and that electric eels can create two types of electrical discharges Authority (ECTS): low voltage and high voltage. When the eels to prey sends, signal the brain via the nervous system to the electric cells. The electric eel generates characteristic electrical pulse in a manner similar to batteries, to produce a stack of plates electrical charge. In the electric eel, some 5000 to 6000 Percent electroplaques able to produce a blow at speeds of up to 500 volts and 1 ampere of current (500 watts).


Electrical current death associated with the current level of current that can be fatal to people, depending on the path electric current takes through the human body, human heart fibrillation (which is reversible with cardiac defibrillator) is can be carried out by currents 70-700 mA and higher.


Juveniles produce smaller voltages (100 volts). Electric eels are a variety of intense electric discharge, using lower discharges for "hunting" and higher intensity for stunning prey or defend themselves. Electric eel also possesses high-frequency sensitive tuberous receptors are unevenly distributed throughout the body that seem useful for hunting other Gymnotiformes. Electric Eels are widely used as a model for studying bioelectrogenesis Electric eels live in fresh waters of the Amazon and Orinoco basins in South America, in floodplains, wetlands, coastal plains and streams. Male electric eels are also much smaller than the electric eel woman. Requires the electric eel in an aquarium for a minimum of 200 liters. Young electric eels often fight if placed in the same aquarium. Electric eels can not be any fish

King crab

 

The Life of Animals | King crab | Golden king crab, Lithodes aequispinus, is captured on the coast of Alaska in the Aleutian chain. Gold king crab is significantly smaller than the king crab red and blue, about 5-8 pounds (2.3 to 3.6 kg). It tastes like the red and blue king crabs, though perhaps sweeter. Note to occur in waters deeper than red king crab, often in the depths of 300 miles (1,800 feet, 550 m). Crabs king's golden youth are intricate and confidence in the structure-forming sessile invertebrates growing on the seabed like corals, sponges, sea whips provide Habitat. Habitat is the main factor that separates the range of red and blue king crabs in the Bering Sea.

 
 

Red king crab, Paralithodes camtschaticus, is a large species, reaching a thickness of 11 heavy shells (28 cm) and a leg extension 6 feet (1.8 m). Its natural range is the Bering Sea, the Aleutian Islands and St. Lawrence Island. You can now also in the Barents Sea and Arctic Europe, where it is drawn, and now it has become a plague of blue king crab, Paralithodes platypus, lives near St. Matthew Island, Pribilof Islands, and the Diomede Islands, Alaska and they are the people of Japan and the Russian king crab from Pribilof Islands are the largest of all king crab, sometimes more than 18 LB (8 kg) weight.

Hermit Crab

 
 
The Life of Animals | Hermit Crab | Most species have long, spirally curved abdomens, which is soft, unlike the hard, calcified abdomens appear in crustaceans. Protected from predators by a salvaged empty seashell Hermit Crab wounded abdomen, where the whole body back. The top of the abdomen is adapted to clasp strongly onto the columella of Cancer hermit snail shell. HERMIT CRAB, as its size increases, it becomes the shell find a large, and not before. The habit of living, but the shell gives the popular name "hermit of Cancer", by analogy with the hermit, who lived a few Hermit Crab species, and land and sea, as "vacancy chain" of the new BUZZ When new, the clay is, hermit crabs collected and formed of all the surrounding him from the modes of the greatest to the least. Cancer Cancer is brought to the maximum with the shell, the maximum time it was published before the new shell is the shell of Cancer,


Hermit Crab species range in size and shape, a species with a few heavy shells religious brevimanus mm long, can live 30-70 years and were approaching the size of a pain. Shell-less hermit Cancer Birger robber (Coconut Crab) This is a terrestrial invertebrates. Hermit Crab zoea larvae hatch, especially in the third stage. Many marine species of hermit crabs is common in the marine aquarium trade. Nearly 15 species of terrestrial world, the following are commonly kept as a concern: Caribbean Hermit Crab (religious and shielded), the Australian land hermit Crab (religious variable) and the Ecuadorian Hermit Crab (religious compressed).

Yeti Crab

 
  
The Life of Animals | Yeti Crab | K. hirsuta was discovered in March 2005, a group organized by Robert Vrijenhoek of the Monterey Bay Aquarium Research Institute in Monterey, Calif. And Michel Segonzac of the Ifremer and the Census of Marine Life scientist's use of the submarine DSV Alvin, operating from RV Atlantis. The discovery was announced March 7, 2006. Hairy pincers contain filamentous bacteria, which the creature can be used to neutralize toxic minerals from the water emitted by the hydrothermal vents, where he lives.


The term "furry lobster" is usually used for family Synaxidae. McPherson et al. Named the genus Kiwa after "goddess of shellfish in Polynesian mythology," but it is the sea in Maori mythology Kiwa Guardian Hirsuta means "hairy" in Latin.
