Rhineura floridana, known commonly as the Florida worm lizard,[4] graveyard snake,[5] or thunderworm, is a species of amphisbaenian in the family Rhineuridae.

The species is the only extant member of the genus Rhineura,[6][7] and is found primarily in Florida but has been recorded in Lanier County, Georgia.

The limbs are absent and, as in other Amphisbaenia, the body is covered by scales arranged in rings giving the animal a worm-like appearance.

[10] R. floridana is a burrower, preferring a soil, sand, or leaf mold substrate, and spending most of its time underground where it is safe from predators.

The diet of R. floridana includes insects and earthworms, but it is an opportunistic feeder and will eat almost any invertebrate small enough to catch.
