The Galliwasp is a kind of lizard that lives under rocks, branches etc. I’ve seen Galliwasps of different sizes while gardening; they hide from me and me screaming, run away from them.
Once, when we found a Galliwasp hiding inside our house, we doused it with insect spray until it died.
Galliwasps are scary looking, shiny and brown. They are known to eat worms and insects. They slither as they move about, so many times you would mistakenly think they are snakes.
