       Tetrapodophis is an interesting snake to say the least since it was the first snake genus known to still have all four legs to be named.‭ ‬For the most part these legs are on the border of being vestigial,‭ ‬yet still‭ ‬defined and‭ ‬functional enough to serve a gripping purpose.‭ ‬Tetrapodophis is also noted for having short neural spines,‭ ‬which may be an indication of an adaptation for burrowing.‭ ‬Altogether,‭ ‬Tetrapodophis has about one hundred and fifty vertebrae,‭ ‬which also shows that Tetrapodophis had evolved to kill prey animals by constricting.
