The Jaguar

endangered-jaguar.jpg

Name : Jaguar

 Class : Mammal                                                                                                                       

Diet : Carnivore                                                                                                                                                                       

Family : Big cat                                                                                                                                                                                                   

 Size : 1,10 – 2 m

 Weight : 136 -185 kg 

Life :24 – 25years

 Habitat : Southern United States  to Argentina ; in the forest or savanna

 Population Global : 2000 individuals

 

        The jaguar’s numbers have fallen primarily as a result of commercial fur hunting, habitat loss, and culling actions attempting to diminish their threat to livestock and humans.

         The jaguar is an endangered species in the U.S., but this species has never been common in the northern part. The jaguar population seems to be decreasing in areas where it is still fairly common. The species as a whole is considered near threatened, and more must be done to keep the jaguar from having its status downgraded to endangered throughout its range.

We must save the jaguar!

    The polar bear

The Polar bear (Ursus maritimus) lives only in the northern Arctic where it spends most of its time on ice caps. It’s the largest land meat-eater in the world and the largest of the bear family. It has evolved to occupy a narrow ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet.

 

                                          

Some characteristics:

  Weight and size :

- Adult male between 350 and 680 kg for 2,6 metres,

- Adult female around 250 kg for 2 meters.

Color: Off-white fur with black nose, eyes and mouth.

They are great swimmers and they can swim at an average of 6 miles per hour. 

They may live 25 to 30 years.

 Polar bears eat mostly seals. They find a seal air hole and sit there until a seal comes up to breathe and then they scoop him right out of the hole.

They will occasionally eat other mammals, eggs or vegetation.

Why is the polar bear endangered?

 

Industrialization has a profound impact on species all over the world.

Hunting is prohibited; polar bears are particularly at risk because their habitat is increasingly threatened by global warming.

When pack ice forms, it melts more quickly, and tends to be thinner as well. In 2004, several polar bear deaths by drowning were recorded.

 

Polar bears have adapted to a high fat diet from ocean-going animals, and their main prey, seals, are contaminated with Persistent Organic Pollutants.

When the seals are eaten, the POPs are absorbed by the bears, and their reproductive ability is being affected as a result.

Mustang Horse :

 

 

endangered-mustang.jpg 

 

1- Introduction.

The Mustang is a Horse Wild which lives in the lowlands of the North West of America. They are herbivore. Two hundred years ago, they are two millions in the United States but now they’re only fourteen thousand. This important decline worries and mobilizes many veterinarians.


2- Why is the Mustang Horse endangered?

They’re killed by the farmers because they eat the grasses which they need for the agriculture, and they are killed too by the hunters. The farmers try to tame them and this lack of freedom sometimes costs their life … They’re disappearing too because their

territory is devastated, throwing place in the industrialization, so there is less area, water and food. Sometimes, a standard, wanting to dominate the herd, fights against the male dominating up to the death.
