Who has not heard about the frogs?From childhood we were told tale "Glove", where one of the characters is a frog-wah.But not all of them are small and harmless.In eastern and southern Africa, as well as in the central US states and southern Canada is home to one of the largest species of these frogs - bullfrog.They grow quite large, on the average from 17 to 20 centimeters.Some of them are 25 centimeters.Their average weight is 2-2.5 kg.But there are some individuals whose weight is much higher than this figure.For example, in 1949 in Washington State caught the frog of the species, whose weight was 3.5 kilograms.
giant bullfrog has a huge head, which resembles the head slingshots - rounded shape with a wide mouth.She has a pretty sharp teeth.Juveniles are colored bright green color, which can be seen against the backdrop of contrasting white spots.Many can be seen along the back of a narrow strip of bright or dark spots.They have bumpy skin that helps them disguise themselves well.Young males have a white belly, sometimes with olive bright divorce.Behind their eyes are large cavities that help them in the mating season.With their help, they make deafening sounds that resemble the bellowing.Perhaps for this reason, this kind of got its name.
Females can not boast of such vivid color, they can be distinguished by the muted olive belly.Bullfrog with age changes its color.It becomes a dirty gray or green marsh.With this coat color in shallow water or in the grass it is practically imperceptible.She has strong hind legs.With their help the frog digs deep burrows.Its activity is observed at night.As for daytime, then they wait out his buried in the ground or coastal sitting in shallow water.
bullfrog has one amazing feature.In the hot season, in order to protect themselves from the scorching heat, it emits cutaneous mucus, which is fully covered.After drying of the mucus, a sufficiently airtight cocoon in which it is placed and the ground.On the surface, leaving only the nostrils.In this state, the frog may spend up to 6 months.
bullfrog, photo confirms considered predatory species.It eats everything that moves, and placed in her mouth and catch the food they need on their own.Dinner can be a variety of insects, reptiles, small rodents, chicks.With a shortage of food they can eat young individuals of the same species.It should be noted that they only react to moving objects.It has powerful jaws with which in seconds can catch prey.Release the jaw is almost impossible, so once in her mouth, the chances of saving anymore.
With the onset of the rainy season bullfrog is preparing for the breeding season.They gather in small flocks on small ponds, where the males begin their song to lure females.2 days after mating, the female lays eggs, which consists of 3,000-4,000 eggs.Then she lays two clutches at intervals of 3 weeks.After 2 months, the tadpoles emerge, the amount of which reaches 20 centimeters.They have olive color and large protruding eyes.Tadpoles develop within two years.Due to the fact that normal frogs do not care about their eggs, most eggs die.However, this can not be said about the African frogs.Males of this species carefully guarding their young.Defending their tadpoles, and they can attack on humans.
