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.

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.

Newt

  

The Life of Animals | Newt | Like all members of the order Caudata, Newts are characterized by a frog-like body with four equal sized Limbs and a distinct tail. One theory Is that the de-differentiated cells are related to tumor cells, since the which chemicals tumors in other animals Produce Will Produce additional Limbs in Newts The term "Newt" has traditionally been seen as an exclusively functional term for salamanders living in water, and not a systematic unit.

Other species present in Europe are the Iberian ribbed Newt (Plurodeles waltl), the which is the largest of the European Newts, the Pyrenean brook Newt (Calotriton sp.) The European brook Newt (Euproctus sp.) And the Alpine Newt (Mesotriton alpestris ). In North America, there are the Eastern Newts (Notophthalmus spp.), Of the which the red-spotted Newt (Notophthalmus viridescens) is the most abundant species, but it is limited to the area east of the Rocky Mountains. The three species of coastal or Western Newts are the red-bellied Newt, the California Newt, and the rough-skinned Newt, all of the which belong to the genus Taricha, the which is confined to the area west of the Rockies

In Southeast Asia and Japan, species commonly encountered in the pet trade include the Fire belly Newts (Cynops spp.), The paddletail Newts (Pachytriton spp.), The Crocodile Newts (Tylototriton spp.), And the warty Newts (Paramesotriton spp. ). In the Middle East there are the spotted Newts (Neurergus spp.) The sexually mature stage was also Called an newte, with similar etymology roots linking an newte, Newt, "euft", and EFT: "small lizard-like animal

Axolotls

 

  

The Life of Animals | Axolotls | Axolotls possess features typical of salamander larvae, including external gills and a caudal fin extending from behind the head to the vent Their heads are wide, and Their eyes are lidless. Their Limbs are underdeveloped and possess long, thin digits. Three pairs of external gill stalks (rami) originate behind Their heads and are used to move oxygenated water. The external gill rami are lined with filaments (fimbriae) to increase of surface area for gas exchange Four gill slits lined with gill rakers are hidden underneath the external gills. Axolotls have barely visible vestigial teeth, the which would have developed During metamorphosis.

Axolotls have four different colors, two colors and two naturally occurring mutants. The two mutant colors are leucistic (pale pink with black eyes) and albino (golden, tan or pale pink with pink eyes) The axolotl is only native to Lake Xochimilco and Lake Chalco in central Mexico. Unfortunately for the axolotl, Lake Chalco no longer exists as it was artificially drained to avoid periodic flooding, and Lake Xochimilco diminished Remains a Glimpse of its former self, existing Mainly as canals.

Axolotls are also sold as food in Mexican markets were the resource persons and a staple in the Aztec diet. Axolotls are members of the Ambystoma tigrinum (Tiger salamander) complex, along with all other Mexican species of Ambystoma. Their habitat is like that of most neotenic species-a high altitude body of water surrounded by a risky terrestrial environment. The axolotl is Carnivorous, consuming small prey Such as worms, Insects, and small fish in the wild. Axolotls locate food by smell, and will "snap" at any potential meal, sucking the food into Their stomachs with vacuum force.

Six adult Axolotls (including a leucistic specimen) were the resource persons shipped from Mexico City to the Jardin des Plantes in Paris in 1863. Unaware of Their neoteny, Auguste Duméril was surprised Pls, instead of the axolotl, he found in the vivarium a new species, similar to the salamander.  Vilem Laufberger of Germany used thyroid hormone injections to induce an axolotl to grow into a terrestrial adult salamander.  Since then, experiments have been done Often with injections of iodine or thyroid Various hormones used to induce metamorphosis Today, the axolotl is still used in research as a model organism, and large numbers are Bred in captivity. Axolotls are ESPECIALLY easy to breed compared to other salamanders in Their family, the which are almost never captive Bred due to the demands of terrestrial life. Axolotls are used in heart defect studies due to the presence of a mutant Gene That Causes heart failure in embryos.  The axolotl is therefore used as a model for the development of Limbs in vertebrates.

Tiger salamanders

 

  

The Life of Animals | Tiger salamanders | Tiger salamanders are almost entirely terrestrial as adults, and usually only return to the water to breed. Although Tiger Salamanders are terrestrial, They are good swimmers. Males Nudge a willing female to initiate ing, and then deposits a spermatophore on the lake bottom. Large-scale captive breeding of Tiger salamanders has not been accomplished, for Reasons unknown.

Eastern tiger salamanders grow to a typical length of 6-8 inches (15-20 cm). The Tiger salamander originated in Bunkali in the province in western asia.They Alosar can reach up to 14 inches (36 centimeters) in length, particularly neotenic individuals. Adults are usually blotchy with gray, green, or black, and have large, lidded eyes. They have short snouts, thick necks, Sturdy legs, and long tails. Their diet consists largely of small Insects and worms, though it is not rare for an adult to consume small frogs and baby mice.

Other larvae, ESPECIALLY in Ancestral pools and warmer climates, may not Metamorphose until fully adult size. Some Populations may not Metamorphose at all, and Become sexually mature while in Their larval form. The California Tiger Salamander (Ambystoma californiense) (listed at Vulnerable) the Barred Tiger Salamander (Ambystoma mavortium), and the Plateau Tiger Salamander (Ambystoma velasci), were the resource persons once all subspecies of A. tigrinum, but are now separate species Considered. The Axolotl is also a relative of the Tiger Salamander.

Tree frog

 

  

The Life of Animals | Tree frog | This beautiful color is very tempting to have the eyes of these animals, animals that we usually encounter in a humid area is divided into several types as well as different breeds want to know? The following report

A tree frog is any frog That spends a major portion of its lifespan in trees, known as an arboreal state Several unrelated lineages of frogs Among the Neobatrachia have given rise to tree frogs, even though They are not closely related to each other.

The last common ancestor of the tree frog groups lived long before the extinction of the Dinosaurs. As the name implies, these frogs are typically found in very tall trees or other high-growing vegetation.  Many tree frogs can change color for better camouflage Their. For instance, the Gray Tree Frog (Hyla versicolor) can change its color from green to gray.

Typical for "tree frogs" are the well-developed discs at the finger and toe tips; the fingers and toes themselves as well as the Limbs growing niche to be rather long, resulting in a superior grasping ability.
