Fatal frogs across south america one can find a variety of frog unlike found in europe. apart being different colours, such as yellow and blue, these frogs are poisonous. some of them are poisonous that even touching can be fatal. the embera choco people of colombia have using toxins from frogs for many years in to hunt. however, since the arrival of other types of weapons in the rainforest, the art of making dart guns started to disappear. however, it is still possible to find craftsmen making dart guns the trunks of palm trees. the actual dart is covered from the frog’s skin. the poison will remain strong to kill animals for more a year. about 55 of the 135 species of south american frogs are toxic. the frogs are brightly coloured to warn predators not to touch them. some species of frogs produce toxins may be useful for mankind as painkillers. a number of species are by researchers in the states to investigate the possibility of using toxins for benefit. by licking the frog’s skin scientists judge the level of toxins. there is no danger of being poisoned, though, as frogs in captivity gradually become poisonous.

he fact that wild animals are still kept in limited conditions for the amusement of the human race is a problem that is widely discussed in eco – advocacy circles. Let's try to figure out if this is really as bad as we are told about it.

Positive

Simplify research. Although there are many different lotions that allow scientists to monitor wild animals in their habitats, but their installation requires a lot of financial and physical costs. In addition, if the camera installed in the jungle breaks down, it will need to be replaced – which means even more costs... in other words, placing the animal in the zoo allows you to "not go far" and conduct research on the spot, while not causing the animals discomfort. This moves biology forward, and sometimes helps to preserve individual representatives of the animal world.

Caring for endangered species. Not every animal brought to the zoo was poached – most often it happens just the opposite. This is especially true for those species of animals whose population in nature is declining for one reason or another. Placing them in a zoo allows scientists to monitor the state of the species, its population, and take the necessary measures to preserve it.

Safety. In addition to the one hundred percent chance to continue their kind due to the conditions created for this, animals kept in zoos have another decent advantage: they are protected from natural selection. The zoo staff does not care, for example, if one lion cub from the litter turns out to be weaker than another and could not get food for itself in the wild - all the lion cubs will be taken care of. The same thing will happen if, for example, an animal gets sick – they will definitely come out and save it, which will not happen in the wild. Finally, the herbivores living in zoos can not be afraid of a predator attack, as they will be separated by several enclosures.

Visibility. Although the opportunity to stare at the locked animals may sometimes seem like a privilege of an impudent person who has nothing sacred in relation to nature, very often a visit to the zoo can be equated with an educational excursion. This is especially important for schoolchildren, when they can see firsthand the animals that have just looked at them from the pages of biology textbooks.

Cons

Space restriction. Of course, after the wild nature, a cramped enclosure will seem like a prison, not to mention the conditions of detention. There is a difference between the endless jungle and fields where you can walk forever in search of delicious grass or flocks of unsuspecting antelopes, and a small room in which you put the right food without having to look for it. In addition, the difference in climate can affect: an animal of the far north, for example, a polar bear, will feel disgusting even in a temperate zoo.

Constant human attention. Unfortunately, few visitors to zoos are familiar with the culture of communicating with animals, and warning signs help only in rare cases. For example, many people think that ducks can be fed bread slices, although this is not true – in fact, these pieces are too large, which makes it difficult for even an adult to digest them. The lack of attention of the zoo staff leads to serious health problems.

Ill-treatment. This seems to be the least of the evils, because everyone is accustomed to believe that only those who love nature and therefore will not allow themselves to mistreat animals go to work in the zoo. Alas, the love of animals is a stretchable concept, and no one has been able to heal the elementary human cruelty, short-sightedness, and negligence so far. Animals that lack attention and care can die, which would not happen in the wild.

"Domestication" of animals. An animal born and raised in captivity can never become a full-fledged inhabitant of the wild. This is a God-knows-what drawback, because cases in which an animal needs to be taken out are very rare. However, in a situation of extinction of a species, when one representative is wild, and the second is from the zoo, mating may not occur due to the unattractiveness of one of the partners and the inability to survive in the wild.

Conclusion

Not all zoos are as bad as they seem. If the animals are watched by people who really know what they are doing, these organizations do much more good than harm. But if it is obvious that the management of the zoo is not coping with its duties, and the animals are suffering, it is necessary to sound the alarm and take action. To do this, of course, you need to be very careful.

Outward appearance

In the books, Hermione is described as having "bushy brown hair"and brown eyes. Her front buck teeth, already very large, grow uncontrollably in Goblet of Fire after she is affected by a spell cast by Draco Malfoy. Madam Pomfrey attends to her in the hospital wing and, at her request, shrinks the teeth down to a normal size that matches her mouth. In the films, her hair is less bushy and she always has regular teeth.

There is controversy over whether Hermione's skin color was ever categorically established in the books. Some take as proof a line from Prisoner of Azkaban: "Hermione's white face was sticking out from behind a tree." They interpret this to be a direct description of her skin color. Others interpret it as a description relative to her usual complexion, arising due to fright and anxiety as she watches Harry Potter's attempt to save the hippogriff Buckbeak from execution. J.K. Rowling herself states that Hermione "turned white" in that she "lost colour from her face after a shock."

Conversely, another description from early in Prisoner of Azkaban can also be cited: "They were there, both of them, sitting outside Florean Fortescue's Ice-Cream Parlour, Ron looking incredibly freckly, Hermione very brown, both waving frantically at him."Some claim that this is a direct description of her skin color, while others claim that it's a relative description of the results of a tan acquired over the summer break.

Personality

Hermione's most prominent features include her prodigious intellect and cleverness. She is levelheaded, book-smart, and always very logical. Throughout the series, Hermione uses the skills of a librarian and teacher to gather the information necessary to defeat Voldemort, the "Dark Lord". When in doubt, it is to the school library that Hermione always turns to. She is often bossy yet unfailingly dutiful and loyal to her friends—a person who can always be counted on. J.K. Rowling stated that Hermione is a person that, "never strays off the path; she always keeps her attention focused on the job that must be done." Despite Hermione's intelligence and bossy attitude, Rowling says that Hermione has "quite a lot of vulnerability in her personality," as well as a "sense of insecurity underneath," feels, "utterly inadequate... and to compensate, she tries and strives to be the best at everything at school, projecting a confidence that irritates people." During her Defence Against the Dark Arts exam at the end of Harry Potter and the Prisoner of Azkaban, Hermione reveals that her biggest fear is failure after a Boggart takes the form of Professor McGonagall and tells her that she has failed all her exams.

Hermione is extremely compassionate and is very quick to help others, especially those who are defenceless, such as Neville Longbottom, first-years, House-Elves, fellow Muggle-borns, half-giants like Hagrid, and werewolves like Lupin. It was revealed by J.K. Rowling after the publication of the final book that Hermione's career in the Ministry was to fight for the rights of the oppressed and disenfranchised (such as House-elves or Muggle-borns). Hermione is also very protective of her friends and values them so much that Rowling has suggested that, if Hermione had looked in the Mirror of Erised, she would have seen Harry, Ron, and herself "alive and unscathed, and Voldemort finished." Hermione has also learned to ignore what bullies such as Draco Malfoy say to her, often preventing Harry and Ron from retaliating and thinking of some way to outsmart him. She accepts her status as a Muggle-born witch, and states in Deathly Hallows that she is "a Mudblood and proud of it"
