I love these! I would not be surprised to find out this is true about the dolphins. There are some extremely intelligent creatures in the ocean, one of which is definitely the dolphin.
I think there is more going on with these than what means the eye. The people who created them know some stuff.
I think you will appreciate this site. It gives a little history behind some of these sculpures. Some look quite ancient, especially those heads.
Despite the description of the sculpture that looks like waves or a snail, I cannot help but to notice what is a slight resemblance to The Eye of Horus.
Very interesting stuff, and great captures Akiroq!
