The increase progress of the human civilization produces annually serious damage in the animals environment from all over the world. Some of the rarest animals in the world in 2013 do not overcome 10 specimens. The over-exploitation of the animals, massive deforestation and climate change cause an unbelievable, extinction of 27,000 animal species annually.

Humans must become more responsible to preserve the last exponents of this rarest animal species to avoid unfortunate extinction. Only few months ago, by the end of 2012, a dramatic lost has been produced. The Lonesome George, the only male from the Pinta Island tortoise breed, died. George was regarded internationally as an icon for conservation.
Here is a top of five the rarest animals in the world in 2013. Some of them are the only
exponent of their species.
1. Rabbs’ fringe-limbed treefrog
The little frog is the last known specimen and it lives at the Atlanta Botanical Garden in Georgia. The Rabb’s fringe-limbed tree frog comes from a small area of Panama. In 2006 a fungal pathogen causes the dramatically extinction of the frog’s population.
Until 2012 he had another male companion. Unfortunately, the same devastating infectious disease caused a serious decline in the health and behavior of the male. The member stuff from the Atlanta Botanical Garden decided to euthanized the frog to avoid the dramatic lose of the precious genetic material.

2. Baiji dolphin
The Baiji river dolphin is one of the smallest species of dolphins and is was declared functionally extinct. Today there is only one specimen known to be alive. Experts say that even if there were few more alive, their number would be too small to be genetically viable. A dolphin adult from this breed reaches a lenght of up to 2,3 meters and weights 135 to 230 pounds. They can be found only in China’s Yangtze River.

3. Yangtze giant softshell turtle
Yangtze giant softshell turtle is considered the largest freshwater turtle in the world. There are only four individuals still alive. They can be found in two places: two of them live in separate lakes in Vietnam and the other two in Suzhou Zoo in China. The turtles from China are a female and a male. The male is too old as all the numerous eggs the female lays annually are infertile.

4. Red-crested tree rat
The existence of this specimen became known in 1898 when two specimens were captured in Columbia. Since then their breed was declared extincted. But in 2011 a group of biologists discovered another specimen while they were camping. The life history of this rat, as well as its habitat preference, is completely unknown. Also, it is uncertain whether the rat recently discovered is the only specimen alive.

5. Hula painted frog
Before their habitat twas destroyed by humans, this species lived in the Lake Hula marshes of Israel. Initially, the breed was considered completely extincted, but during a routine patrol in the Hula nature reserve, one specimen was found. This lead to elaborate searches that ended with the discovery of ten more species.
