I saw this one a while back on the spanish channel. I wanna say it was "not from this earth 1988 version" but I watched that and it wasnt the one. This manta ray looking alien thing would float above the ground, and kinda swallow people up, but it would dissolve them into steaming guts that fell on the ground. I am pretty sure it was a B movie. ANyone have any ideas? PLus it seemed like an 80's movie based on the quality of effects.
