I've just read first time about "skyfish" here http://www.membrana.ru/ Sorry, it's in russian, but you can see pictures of these creatures. Does they really exist? [and from another] I found an English site: http://paranormal.about.com/
We have mentioned that mankind only is aware of approximately 1/1000 of the subatomic particles that we, the Zetas, are aware of. Many atoms form crystals, a fact mankind is aware of because he has discovered diamonds and other crystals formed in nature. These are crystaline structures that have, from mankind's standpoint, a permanent structure. They last. Crystals that are ephemeral are not so well known. What mankind is discovering in rods and skyfish are these ephemeral crystals.
