Can you give any positive evidence or than your baseless claims for any of the supposed animals you keep claiming are true?
Mokele Mbembe, Bigfoot, Loch Ness Monster, any of them? You keep making vague claims, lets see some links that support your claims, I can sit here and type baseless claims all night, I can give links to claims of perpetual motion, I am quite sure that they would be soundly thrashed but it would at least be supporting the claims as best you can.
I was trying to get you to look at the evidence for the seahorse of lake titicaca for a reason, the reason is why even science can be fooled and often non scientific claims are made to appear as though they are made by scientists and sometimes even picked up by scientists and professional science like museums can be fooled.
To find out if something is supported by evidence you have to look past what you want to see and hear to what is actually real.

You would be amazed at how many sources still cite the lake titicaca seahorse as real and still make claims the lake is full of marine species of fish when in fact it is not. Just too many red wagons are attached to the idea the lake contains marine species of fish and too many cart are overturned when the reality of the claims are known....
Mokele mbembe is fairly easy to see through, no actual scientist has accepted any of the proposed evidence as viable and everything from ecology to paleontology would appear to indicate there is no way a population of sauropod dinosaurs could have survived for 65 million years.
The Loch Ness Monster has no supporting evidence and the lake itself is too small to support a population of large aquatic creatures and too cold for them to be reptiles and too empty of food for population of such large creatures to feed.
Bigfoot is interesting in many ways due to it apparently actually having a creature it could actually be that was alive a reasonable amount of time ago but when you look closely you will find that the large ape it is based on looked much more like a gorilla and did not walk upright like a man and to say that native american legends support bigfoot would also have to lend credence to such creatures as thunderbirds and wengingos to name but a couple.
This is not to say that cryptozoologists have never found unknown large animals, they have:

native legends are not a good source of information about actual fauna of an area any more than the bible is a good source for unicorns or dinosaurs..
