Relating to or characteristic of amphisbaenas, especially their unusual two-directional movement and body structure.
From 'amphisbaena' + the suffix '-ian' meaning 'relating to or belonging to', a descriptive term in herpetology.
Amphisbaenian locomotion is totally different from regular snakes—they use their heads and tails to move in a unique side-to-side wriggling motion that looks alien compared to how other reptiles crawl.
