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.

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.
