Most people DO believe that frogs are bad, they bring a lot of inconveniences and even warts. They live in marches and do nothing but spoiling our lives. But it is a disbelief, sometimes they can please our eyes.
Here we will talk about tropical frogs, they are colored, bright and draw attention every time you see them. Unfortunately, very often we spoil frogs lives much more often then they do. Some people even chase them. Very often we forget about our ecology, how drastic it is and feel no compassion to these small creatures, who are extremely vulnerable to any event occurring in the nature: climate, environmental conditions, urbanization. Many species became extinct, as they were not able to adopt to new living conditions. A lot of scientists, research establishments try to avoid this process and stop its development.
As an example, let’s take Dendrobatidae or commonly known as Dart-poison frogs, they live in American tropics and suffer from deforestation. Nowadays, there exist not more than 100 species of them, but these frogs are not capable of living under other natural conditions. One can say, they deserve dying! But it is unfair! These frogs are of great help to medicine. Yeah, no doubts, since the time immemorial, they have been producing a very toxic poison, small portion of this poison (not more than 1 or 2 usual salt grains) is enough to kill a person. Also, this poison was used by Indians to make poisonous arrows and to kill enemies. But, as scientist started studying them, they found out invaluable information about ingredients of their poison and about membrane functioning, because poison of some frogs strikes directly the membrane of a person and provokes apoplexy. Poison of some species can kill 800 people.
Bodies of these frogs are covered with special liquid poison – it kills small insects and animals. But, 136 micro grams of this poison can kill a person. All poisonous frogs have bright colored appearances! WHY? Because in such a way they warn predators – don’t touch us, it can end awfully. So, it is a kind of protective-warning coloring.
Interesting fact! These frogs are not poisonous in captivity (zoos, research areas). Scientist can explain it as they don’t eat special insects, which provoke the producing of poison. The most dangerous frog in this family is a Golden Poison Dart Frog.
sometimes bigger than housecats, they are attractive rodents. Actually, every marmot is associated with the only one US holiday, named after an animal. Yeah! It is exactly, Groundhog Day. In North America there are a lot of zoos and recreational parks, very their enormous visitors can observe marmots in their natural life-conditions.
So, now it is time to speak about Marmot’s day!
d, what is even more awful, without their lives!
Chinchillas are very popular nowadays, they live both in Zoos, stores and even at homes! But there are some strangers, they still don’t know, how do chinchillas look! It is a tricky question, I can give a lot of descriptions, but than you will be puzzled, so, one, but all-absorbing: chinchillas are cute creatures familiar to big squirrels with huge ears (like Cheburashkas).
