Aipysurus tenuis has more than 170 ventrals, A. mosaicus has 140–154. Aipysurus duboisii, A. fuscus, A. laevis, and A. pooleorum have more than 17 scale rows around midbody and at least some of the head shields are usually broken up into smaller plates, A. mosaicus has 17 scale rows around body and head shields that are normally symmetrical and not broken up.
