it's blind due to that it lives most of it's life underground, but it hunts by listening for it' prey, unless they reach solid rock, but the graboid will wait them out until they move
Yea XD
and if they were real
avoid the middle of Nevada and small parts of Mexico
that's where they travel
they will pretty much eat anything that moves
but thanks to it's tasting/grabber tentacles it will spit out if not editable
it seances vibrations in the ground and can go through dirt with ease but not solid rock
