Unusual cow and where does the Internet?

We are beginning to get used to trust information that we find on the Internet, but is it always reliable?


Lyrics.

Tired of walking through the woods, I decided to rest lying on the couch, cut in a zomboyaschik for the background, knowing that he did not melt my brains. On the first channel was the transfer of "Who wants to be a millionaire?" There was a question, literally, I don’t remember, unfortunately, but the emphasis was laid on the fact that this animal does not now live on our planet. In the list of four was the animal "Sea Cow" and it turned out to be extinct. I was very surprised, because visiting 2 years ago, Egypt went to look at these same cows, but the truth is they called them Dugongo. I decided to check, because when visiting sea cows, some of the tourists, before the dive, said: “they are all extinct”.

Yes, and in the news chronicles you can find that she is still dying.

Yandex has nothing to do with it - he completed his task, found the material.

But the question remains what to believe?

Or

Is it always possible to find reliable information using the Internet?

I wonder if anyone can prove through the Internet whether she died or not?
