The Java tiger disappeared in 1994​

In the case of these impressive cats, which were seen on their last legs in the mountainous areas of the island, an increase of farmland destroyed their habitat. Human action therefore indirectly caused its population to shrink until the Java tiger disappeared in 1994.

Golden toad: a warning against global warming​

According to biologists, the golden toad, an animal in the pools of the Monteverde cloud forest of Costa Rica, was a victim of climate change. It was seen for the last time in 1989.

The Golden toad's home dried up​

Global warming caused the disappearance of the humidity that this species of amphibian needed to live and procreate. The ponds that made up the golden toad's ecosystem dried up, which also caused the mists that provided necessary moisture to disappear.

Mexican grizzly bear: beyond Canadian lands​

Today, grizzly bears are a symbol of Canada, but in the past, we could see this imposing animal in other areas of the American continent as well. An example was Mexico.

The Mexican Grizzley went extinct in 1964​

The Mexican grizzly bear was considered officially extinct in 1964, and by the beginning of that decade there had only been 30 bears left. The reason for their disappearance was hunting by farmers in the area where they lived. The farmers responded to the grizzly attacking their livestock and killed them until there were none left.

Alabama mussel: victim of contamination​

In the sea and rivers there are many types of animals that oftentimes we do not take into account. This was the case of the Alabama mussel which could be found in the Mobile River and which performed the important function of filtering polluted water from the riverbed.

The Alabama mussel disappeared in 2006​

The mussel disappeared from Alabama around 2006 due to dangerous products being dumped in the area, which also hurt the people who lived in that area.

Gastric brooding frog: the truncated dream of a cure to ulcers​

The gastric brooding frog disappeared, according to experts, in 1981. Originally from Australia, this amphibian, apart from having a rather peculiar reproductive process, was also the subject of studies to achieve a cure against ulcers.

A frog that gave birth via its mouth​

To reproduce, the frog would swallow the fertilized eggs to incubate them inside. Its stomach would then swell until the moment of "giving birth," in which its ready-made and upright young would come out of its mouth.

Blue macaw: sad ending despite warnings​

Anyone who has seen the animated film 'Rio' (2011) will be familiar with this animal. The characters Blu and Perla were two blue macaws. It is important to cite this movie because it already warned (unsuccessfully) of the danger that this species would disappear.

The Blue macaw was declared extinct in the wild in 2019​

The blue macaw has since become one of the latest species to be declared extinct. Endemic to Brazil, the blue macaw has perished from deforestation and from hunting for sale as exotic birds.

Caribbean monk seal: ravaged by human greed​

It wasn't long ago that seals could be seen in the Caribbean. They were native to the area, extending their territory between the north coast of South America, the east coast of Central America, and the Gulf of Mexico.

Last seen in 1952​

Little by little, the seals' population was reduced until it existed only on the Serranilla Bank between Jamaica and Nicaragua. There, the last Caribbean monk seal was seen in 1952.
Man is behind the main causes of its extinction: hunting - for the oil that could be extracted from their body fat - and overfishing.

Miss Waldron's Red Colobus: collateral effect of deforestation​

This species of monkey lived on the African continent, between the borders of the Ivory Coast and Ghana, but it has been considered extinct since the beginning of the 21st century.

 

[jw5]

Deforestation led to inbreeding​

The red colobus used to move at great heights between the trees, but its groups were reduced due to the deforestation of their habitat, which exposed them to predators. The practice of inbreeding finally weakened their species. The sum of these problems led to the Red Colobus' extinction.

Black emu: a unique species that lived on King Island​

We can still find different types of emus on our planet, but we will never be able to see a black emu again. This species lived only on King Island, Australia.

Humans finished off the black emu​

Humans finished them off long ago - back in the 19th century - when the island was colonized and the species was reduced by the action of men until it disappeared forever.
