Oryx

 

The Life of Animals | Oryx | The term "Oryx" comes from the Greek word Ὂρυξ, oryx, a type of antelope. The correct plural is óryges although oryxes established in English. The Arabian Oryx the smallest species, became extinct in the wild in 1972 in the Arabian Peninsula. One of the largest populations of Arabian Oryx is in Sir Bani Yas Island in United Arab Emirates. Additional populations are again in Qatar, Bahrain, Israel, Jordan and Saudi Arabia. In 2011, the IUCN threat category of degraded vulnerable extinct in the wild, the first species to extinction in the wild back to the vulnerable state.


The Scimitar Oryx, also known Scimitar-horned Oryx (Oryx dammah) of North Africa is now listed as possibly extinct in the wild. The East African Oryx (Oryx Beisa) inhabits East Africa, and the closely related Gemsbok (Oryx Gazella) lives in South Africa. The Gemsbok is monotypic, and the East African Oryx has two subspecies, East African Oryx "adequate" (Oryx Beisa Beisa) and Fringe-eared oryx (Oryx Beisa called otis).


All species oryx prefer desert conditions and can survive for long periods without water. They live in herds of 600 animals. Males and females have a permanent horns. The horns are narrow and straight, except for the Scimitar Oryx, which curve backwards like a scimitar.

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.

Lizard Sailfin

 
  
The Life of Animals | Lizard SailFin | Malaysian Sail finned Lizards grow 0.9144m (3 feet) in length. These lizards have a small head with a long snout and nose oval near the tip of the snout. In the head and the muzzle is usually a top of some large scales and small scales. Fingers and toes have lobes of skin. The Sail finned Lizards characteristic is only the tail, which is twice the length of the head and body together.


The flattening of the tail helps the lizard swim. They are stocky lizards that are dark green-brown with black spots. These lizards are found in Indonesia, New Guinea, Philippines. Young people can be found in ditches and around people. The lizard males are combative and competitive against other males when trying to court the females.


Browse fins Lizards feed mostly on plants, but also are known for insects, rodents and millipedes eat, people eat prey is worth 60% and 40% of the plants. Amboinensis lives Hydrosaurus 15 years or more.

Chinese Fire Belly Newt

  
The Life of Animals | Chinese Fire Belly Newt | In AD 1008 years, a Chinese author mentioned that a small black salamander was found in aquatic weeds in pools on the prairie Mou. For animals that survive the transportation, mortality rates are very high given the poor cattle in pet stores or the ultimate owner. If the animals in captivity can not be found, make sure to buy an animal in good condition. Open wounds, missing limbs, fungi and animals too thin to be passed over, or even seemingly healthy individuals if the newts deaths are in the tank. While many people buy sick animals, out of pity or with intent to breastfeed return to health, the purchase of these animals simply encourages poor care on behalf of the owner of the pet. Orientalis Cynops better in a tank not heated to temperatures between 58-68 ° F (14-20 ° C). Temperatures above 74 ° F typically result in high levels of stress or death. The failure of newts to enter the water can be a sign of stress, poor water quality, or other health problems. Typically, five gallons of aquarium animals is ideal, but the smaller tanks may have water quality problems.


Including live plants in the aquarium can help maintain healthy water quality, providing coverage for pregnant newts and more attractive. Animals mixture of other amphibian or fish or other, with C. orientalis is discouraged Other animals can be aggressive, disease-carrying foreign, have different requirements for housing, and may eat or be eaten by the newts. Firebelly toads (Bombina orientalis), newts Paddletail (Pachytriton spp.), Crabs and various fish are often poorly maintained together in pet shops. Moreover, several toxins newts can be fatal to other species. Few species of fish from cold water fish like small white clouds are generally considered acceptable as cohabitants of C. orientalis, but they can still carry diseases, parasites or be eaten by newts hungry.

 

Newts in captivity can eat chips or dried foods, although some animals may refuse it. Foods that are easily taken may include bloodworms are the larvae of chironomids, worms, water fleas, such as Daphnia, Artemia adults Blackworms or mosquito larvae. Newts can also eat tadpoles and small fish, but these foods have a higher risk of transmitting diseases and parasites, are wild caught. Aquatic plants and layers of plastic strips (thin strips of clear plastic garbage bag tied to a rock or other heavy object) works fine, and plastic strips may be preferable to living plants. The eggs are deposited or placed in plastic plants, with some eggs laid each day.

Chaco Horned Frog

 
 
The Life of Animals | Chaco Horned Frog | Cranwell of horned frog (Ceratophrys cranwelli), also known as the Chaco horned frog, a frog is endemic to dry land of the Gran Chaco in Argentina. Like most members of Ceratophrys generally, are often considered Pacman frogs because of their resemblance to the popular video game character of the same name. The backs of these frogs are usually dark green and brown coloration, although albino variants with orange and yellow back even exist. The model allows to camouflage dark color as the animal burrows and waits for its prey.  In the case of extreme temperatures, Cranwell frogs enter a period of aestivation, the development of a thick protective layer of the skin to retain moisture and aid in breathing. When estivation is complete, the frog uses its front legs and rear to help remove the protective layer. In many cases, the frog uses the jaws to pull the skin on the back, often eat the skin in the process.


How Pacman frogs, Cranwell are popular as pets. The foreign body can be anything, but Pacman frogs kept as pets, usually a small stone or piece of gravel used as substrate. In severe cases, the volume of stool in the intestine is so great that the lungs are clogged and respiration of the frog is compromised.

Cane Toad

 
  
The Life of Animals | Cane Toad | A huge cane toad women more than men reach an average length of 10-15 cm (3.9 to 5.9 in). Held "Prinsen", a toad as a pet in Sweden are listed in the Guinness Book of Records as the largest recorded pattern. Individual cane toads can be gray, yellowish, reddish brown or olive brown, with various patterns. Juvenile toads cane is much smaller than adult cane toads 5-10 cm (2.0 to 3.9 inches) long. Tadpoles in the range of 10 to 25 mm (0.39 to 0.98 inches) long. The title "Marine Toad" and the scientific name Bufo marinus suggest an association with marine life, and adult toads cane entirely terrestrial, just dare to breed in fresh water. While the growth rate varies by region, season and sex, and train train find average initial growth rate of 0.647 mm (0.0255 inch) per day, and then averaged 0.373 mm (0.0147 inch) per day. The growth is slowing is usually only toads sexual maturity, the rapid growth of their survival during metamorphosis and sub-adult, losing young toads to their toxicity, which protects them, such as eggs and tadpoles, but not yet fully developed parotoid glands much produce bufotoxin the Because they do not have this key, it is assumed that only 0.5% of the cane toads in adulthood


As in the growth rate varies, the point at which the frogs become sexually mature in different regions. In New Guinea, the sexual maturity of the female toads snoutvent length of 70 to 80 mm (2.8 and 3.1), while the toads reach maturity in Panama, when they are between 90 and 100 mm (3.5 and 3.9 inches in) long. Cane toad has a high resistance to water loss, a study showed that some of them can resist the 52.6% loss of body fluid that they can survive outside the tropical conditions. Adult skin is poisonous cane toads, as well as an enlarged parotoid glands behind the eyes and other glands on their backs. When the toads are endangered, glands, milky-white liquid bufotoxin known. Bufotoxin components are toxic to many animals, there were even human sacrifice in connection with the consumption of cane toads. Bufotenine, a chemical substance secreted by cane toad is classified as a Class 1 drug under Australian law, along with heroin and cannabis. It is assumed that the effect of including similar to a light bufotenine poisoning stimulation, mild hallucinations, takes less than an hour as a cane toad bufotenine allocated in small amounts, and other toxins in relatively large quantities, could lick toad in serious illness or death is run.


In addition to the production of a toxin capable of cane toad inflating its lungs, puffing, lifting his body off the ground it more and more of a potential predator Toxic toads sausages with meat are currently trying in the Kimberley (Western Australia) to, to protect domestic animals from the lethal effects of cane toads tested. Mixing bits of toad cause nausea chemical, bait animals trained to stay away from amphibians. Many species prey on cane toad in their homeland. Predators outside the natural range of the cane toad include Whistling Kite (Haliastur sphenurus) Rakali (Hydromys chrysogaster), black rat (Rattus Rattus) and the Water Resources Act (Varanus Salvator).


There have been occasional reports of Tony Frogmouth (Podargus strigoides) and Papuan Frogmouth (Podargus papuensis) eating cane toads. It is likely that the opossum Didelphis genus of cane toads can eat with impunity. Besides the already mentioned use as biological control of pests, cane toad has used in several commercial and noncommercial applications. Traditionally, the natural habitat of the toads in South America, "milking" the toad, the Embera-Wounaan their toxins which are then used as arrow poison.


The toad has parotoid glands as a source of food hunting in some parts of Peru and eaten after removing the skin. Pregnancy tests were in the middle of the 20th Century by the introduction of the urine performed by women in the male toad lymph sacs, and if the sperm appeared in the urine of the toad, the patient is pregnant. Is considered ideal in experimental animals cane toad, they are plentiful and easy to maintain and operate and inexpensive. Even a dead toad matter. Cane toad skin was stuffed into the skin and novelty items cane toads, supplied and installed, has found a home in the tourist market, as well as attempts to produce fertilizer from their bodies.

African frog

 
 
The Life of Animals | African frog | African frogs are carnivorous and voracious eaters, feeding on insects, small rodents, reptiles, small birds and frogs, amphibians, and positive, and is known to bite when provotsirovali.Afrikanskie frogs kept at Pretoria Zoo in South Africa once ate 17 baby cobras (Hemachatus haemachatus). The African frog (Pyxicephalus adspersus) is a species of frog in the family Ranidae. The natural habitat is dry savanna, moist savanna, subtropical or tropical dry shrub, freshwater lake constantly, constantly fresh marshes, arable land, pastures, and channels.



Argentine Horned Frog

  
The Life of Animals | Argentine Horned Frog | Females can be up to 16.5 cm (6.5 inches) from snout to vent (SV) and men was 11.5 cm (4.5 inches) VS. Color is usually light green with red spots, but dark blue, parti-color versions of black and albino exist. Frog hunting horns remaining motionless, waiting for prey. In nature, the typical diet will include rodents such as mice, small reptiles and large spiders and insects such as grasshoppers. Horned frog is known for its reputation for courage. They try to eat animals, sometimes even their size. When kept as a pet, usually horned frogs feed primarily on large adult grasshoppers, crickets and black and brown rats, but also enjoy depending on fish size.

 

Sexual reproduction. Argentine Horned Frog Females lay about 2,000 eggs in water and in two weeks to become tadpoles. Known in the pet industry as Pacman frogs, in Argentina diversity of species is usually resistant and easy care. Argentine Horned Frog has some simple requests such as a pet. A We recommend keeping the horned frogs only way to avoid cannibalism. A heating pad can be used to adjust the temperature, however, the pad should be placed on a water surface and below so as not to prevent overheating frogs buried.


Daily misting with distilled water (hard water stain removal on glass) can help achieve optimal levels of humidity. Do not spray directly to your frogs in distilled water or distilled water to soak offer. Water treated with chlorine, or better, spring water must be used for dipping purposes. Juveniles can be fed appropriate vitamin / calcium dusted 3-4 size every two days. Adults can be fed adult crickets, cockroaches, earthworms or three times a week. Frogs have difficulty digesting the tissues in mammals and high fat content of mice can lead to fatty liver disease.

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

Coelacanth

 
 
The Life of Animals | Coelacanth | Coelacanths are part of a clade Sarcopterygii, or lobe FishBase. Externally, there are some features that distinguish lobe-finned coelacanth fish from the other. They have a three-lobed tail fin fin, as trilobed. A secondary tail, which runs along and extends beyond the tail primary separates the upper and lower halves of the coelacanth. Scales Cosmoid act as a thick armor to protect the outside of coelacanth. There are also several internal features that help differentiate them from other fish lobe-finned coelacanth. The coelacanth is filled with fat braincase 98.5%, only 1.5% of the skull containing brain tissue.


The cheeks of the coelacanth is unique because the opercular bone is very small and has a soft-tip opercular great. The coelacanth has a rostral organ in the ethmoid region of the skull. Latimeria chalumnae and L. menadoensis are the only two known living species of coelacanths. Coelacanth The word literally means "hollow column" because of its unique finned hollow column. The coelacanths are big, fat, fish fins lip that grow up to 1.8 meters.

 

Coelacanth fins Tues 8-2 dorsal fins, two pectoral, two ventral fins, an anal fin and tail fin. The eyes of the coelacanth are very large, while the mouth is very small. The vision of the coelacanth has evolved into an ability to color predominantly blue-shifted. Pseudomaxillary wrinkles around the mouth, to replace the upper jaw, a structure that is absent in coelacanths. The rostral organ of coelacanths in the region of the skull including ethmoid. The body of the rostral coelacanths as part of laterosensory 'used. The reception auditory coelacanth "is mediated by its inner ear. Locomotion of the coelacanth is unique among its kind. Move, use the most coelacanths, up or down Wellings current and drift. Coelacanth can be used to get through the rapid generation of its pulse tail fin. Due to the large number of fins, the coelacanth has high maneuverability. Coelacanth may also guide your body in any direction in the water. It is thought that giving your body the rostral electroperception coelacanth, the helpers, in its movement around obstacles help.


Male copulatory organs not coelacanth course, only a sewer. Coelacanth looks very similar to young adult coelacanthThe yolk sac of the young coelacanth is broad and comes down to the pelvic fins. The scales and fins of the coelacanth young are fully matured. The coelacanth is odontodes missing girl, but she gained during ripening. Reviews state that eat the coelacanth has led to "a kind of diarrhea," and state medical reports .

Bluefin tuna

 
  
The Life of Animals | Bluefin tuna | The bluefin tuna is one of the largest, fastest and most beautiful colors of all fish in the world. Their torpedo-shaped bodies are agile built for speed and endurance. Bluefin tuna are warm-blooded, a rare trait among fish, and are in the cold waters of Newfoundland and Iceland, as well as the tropical waters of the Gulf of Mexico and the Mediterranean Sea where they spawn easily go to every year. You can retract their dorsal and pectoral fins into slots to reduce drag. And some scientists think that the series of "finlets" on their tails may even serve to reduce water turbulence.


Bluefin reach their enormous size of gorging themselves almost always in small fish, crustaceans, squid and eel. The largest ever recorded bluefin tuna was from a Nova Scotia to 1496 pounds (679 kg) caught weighed. Bluefin tuna are eaten by humans for centuries.

 

As a result, the stocks of tuna, especially large, old fish were killed, and international conservation efforts have resulted in a restriction of trade leads out. But at least one group of illegal fishing bluefin populations in Europe, it led to the brink of extinction.
