I suppose it is also possible that mollusk-like creatures live elsewhere in the universe, as well as mammalian-like ETs.
However, I'm not sure how this is disclosure.
It is simply some astrobiology speculation about life elsewhere. I remember seeing a science documentary several years ago science shows where NASA astrobiologists speculated that animals on other planets may shield themselves from radiation by being armadillo-like or turtle-like, carrying their radiation protection with them.
That's not disclosure, either. It's just normal scientific speculation about the possibilities of ET life.
