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!

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.

    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.


                                     endangered polar family

 

 

           

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.

KOALA

 

      endangered-koala.jpg

Name

Koala

County or continent

Australia

Habitat

Eucalyptus forest

Diet

Herbivore

Type

Mammal

It measures from 60 to 85 centimeters and its weight in adult age can vary from 6 to 12 kilograms

Why is it endangered ?:

it is valued for its soft fur.

if a disease is spread among them, they have no resistance against it because of them having the same genetic pool. Therefore they are not immune to disease and if one Koala gets a virus, the whole community is infected by it as well. Often these diseases bring disastrous results and hundreds or thousands or maybe even millions can be wiped out because of a single virus.

their habitat is being destroyed. Besides having no living place, it has lost its source of   food.

As the Koala is a very fussy eater and almost only eats eucalyptus leaves, it has a limited supply of food choice.

ISLAND FOX

 

endangered-fox.jpg    

 

CLASS : Mammal

ORDER :Carnivore  

The Island fox is restricted to six of the California Channel Island.

The Island fox lives in the forest where it is used to eating snakes.

 

Four of the six island fox subspecies have recently suffered marked population declines caused by disease and predation by golden eagles. These four subspecies were federally listed as endangered on 05 March 2004.

The California Department of Fish and Game has classified all island fox as threatened since 1971.

S.O.S Dolphin

 endangered-dolphin.jpg

 

TYPE : mammal

DIET : fish and squid

LIFE SPAN : 40-45ans

Dolphin Social Life : Many researchers agree that dolphins extremely social creatures and actually seem to depend on this interaction while hunting, mating and defending themselves and their pods. Typically, dolphins live and travel in groups ranging from 2-40 dolphins. Research has also shown dolphin pods as large as several hundred members.

Endangered dolphins are a huge concern in our actual society. Why is it a problem? Well, first of all, if such specie like the dolphin is endangered, it means that if this situation is not dealt with properly, soon we might see their specie disappear from our oceans.

 

 

Why are dolphins endangered?

 

There are three main reasons why dolphins are endangered and all of them are related to humans.

1. the first reason is because of tuna fishing .Since both tuna and dolphins follow the same routes, dolphins get caught in the fishermen's nets which are meant to catch tuna. In this case, they get fatally hurt or they drown as a result of it.



2.The second reason is fishing for use in human's cuisine. Nowadays, dolphins are protected by laws but nonetheless between 200,000 and 500,000 dolphins were victimized by fishermen during the 1960-1972 years. Also, even if some laws protect dolphins, it allows a certain amount of dolphins to be accidentally caught which still has a negative impact on the dolphins' species.



3.The last but not least is pollution. Since humans are polluting rivers, seas and oceans, it affects dolphins. Also, since the dolphin is at the top of the food chain, the chemicals that pollute its habitat create the highest level of concentration of these pollutants in its body. As a result, diseases, difficulty to reproduce or even death take their toll on these species.

the leatherback turtle

endangered.jpg 

 

 

             

 

Name: Leatherback Turtle

Type: Oviparous

Diet: Herbivore

Habitat: warm oceans

Size: 6,56 ft (2 m)

Weight: 1 102,31 pounds (500 kilograms)

Lifespan: 50 years

Reasons why it’s endangered:

  The Leatherback turtle is mainly endangered because of water pollution and  plastic bags. Indeed, the water is becoming more and more polluted and the turtles mistake the plastic bags for jelly fish. When they swallow a plastic bag, they can't breathe anymore and die.

                       KOMODO DRAGON

 

endnagered-komodo.jpg    

Lenght : 3.6m

Weight : 136kg

Habitat : Indonesia                                                   

 

Natural History of Komodo Dragons

Komodo dragons are carnivores (meat eaters) and will devour any animal they are capable of . Although they are for the most part scavengers, they sometimes capture live prey, including deer, pigs, birds, even young dragons.

 

Causes of Endangerment of the Komodo Dragon

The current population of Komodo dragons seems relatively stable at about 5,000 animals. Little is known about the species. The dragon's limited distribution makes them highly susceptible to natural or human-caused events, such as storms, fire, or disease.

The primary threats to the dragon's survival include illegal hunting and loss of habitat to human settlement. As was the case with most large, spectacular animals the world over, Komodo dragons were sought as trophies by big-game hunters. They also are killed for skins and feet to make novelties. Early in this century, many Komodo dragons were trapped for sale to zoos and private collectors.

                                                              

Commercial trade in specimen is illegal under the Convention on International Trade in Endangered Species.
