You know... It's something that only is noticed from above. Galapagos island's shape is a blatant sea-horse profile and the own nature in that place is a mystery. A very aggressive environment, volcanic activity everywhere, lack of fresh water, poor vegetation, only one species of terrestrial mammals... some bats, few species of birds, but lots of giant lizards and sea lions. A curious detail is that the gigantic lizards of Galapagos are vegetarians.
I wonder whether ancient aliens carried some genetic experiments in Galapagos, in attempt to see how mammals, reptiles and birds develop and survive in very harsh conditions.
Whoever they were, just put a signature in the place, by shaping the main island like a sea-horse seen from above.
